Full textAbstract:
Farmers and consultants face an unmanageable amount of diverse knowledge and information for crop management decisions. To determine optimal actions, decision makers require knowledge-based support. In this way, decisions can be improved and heuristics can be replaced over time. The study presents a digital knowledge base with an integrated decision support system (DSS), using the example of nutrient supply, specifically nitrogen (N), fertilization. Therefore, the requirements of farmers and crop consultants for DSS to inform fertilization decisions for winter wheat (Triticum aestivum L.) were elaborated using surveys, expert interviews, and a prototype test. Semantic knowledge was enriched by expert knowledge and combined in a web application, the Crop Portal. To map regional and personal decision making patterns and experiences, the tacit knowledge on the complex advisory problem of N fertilization is made digitally usable. For this purpose, 16 fuzzy variables were specified and formalized. Individual decision trees and their interactions with an integrative knowledge base were used to multiply the consulting reach of experts. Using three consultants and nine model farms from different soil–climate areas in Germany, the Crop Portal was tested under practical conditions and the perceived pragmatic and hedonic quality of the system was evaluated using a standardized questionnaire. The field test showed that the variation in fertilizer recommendations from the ‘digital advisor twin’ ranged from 5 kg N ha−1 to 16 kg N ha−1 when compared with the decisions of the experts in the field. The study presents the participatory development and evaluation of a rule-based DSS prototype in agricultural practice.

Full textAbstract:
Climate change will intensify water scarcity, and therefore irrigation must be adapted to save water. Operational tools that provide watering recommendations to end-users are needed. This work presents a new tool, Irrigation-Advisor (IA), which is based on weather forecasts and is able to separately determine soil evaporation and crop transpiration, and thus is adaptable to a broad range of agricultural situations. By calculating several statistical indicators, IA was tested against the FAO-56 crop evapotranspiration (ETcFAO) methodology using local crop coefficients. Additionally, IA recommendations were compared with current standard practices by experienced farmers (F). Six field experiments with four widely cultivated species (endive, lettuce, muskmelon and potato) were performed in Southeast Spain. Irrigation water applied, crop yield, aboveground biomass and water productivity were determined. Crop water needs underestimations (5%–20%) were detected when comparing IA against ETcFAO, although the index of agreement proved reasonable adjustments. The IA recommendations led to water savings up to 13% when compared to F, except for lettuce, with a 31% surplus in irrigation when using IA. Crop yield was not compromised and water productivity was increased by IA. Therefore, IA mimicked the farmers′ irrigation strategies fairly well without deploying sensors on-site. Nevertheless, improvements are needed for increasing the accuracy of IA estimations.

Full textAbstract:
The agricultural conservation practice of prairie strips is new and novel. Prairie strips planted in row crop fields warrants greater adoption because the application decreases erosion; protects water quality; and supports habitat for wildlife and biodiversity, including pollinators. Prairie strips are a vegetative practice composed of diverse, native, and mostly perennial species that, as a community, follow principles of ecological succession; however, they must be managed for success. Farm advisor comprehension of practice characteristics is key for adoption by producers and landowners. This article reports on a developmental evaluation of workshops intended to change farm advisor knowledge, skills, and confidence related to prairie strips management for use in consulting with farmers and landowners. The study used pre-post instruments of knowledge and skill focused on prairie species identification and age of prairie strips planing; pre-then post-end of session questions were asked in a survey to report change in knowledge, skill, and confidence, as well as farm advisor situation. Advisors reported increased confidence, but acquisition of prairie knowledge and skills resulted in flat to lower scores. The paper explores the discrepancy of lower cognitive scores (knowledge and skills) compared to higher confidence. Explanations explore the phenomena of satisficing and perceived self-efficacy to explain the differential.

Full textAbstract:
An inter-organizational certificate course i.e. Certified Farm Advisor (CFA) in Organic Farming was jointly organized by National Institute of Agricultural Extension Management (MANAGE), Hyderabad and ICAR-Indian Institute of Farming Systems Research, Modipuram, Meerut during 2019. The objective of this certificate course was to create a cadre of “Certified Farm Advisors†in appropriate technologies of organic farming and enable them to deliver effective “Technical Advisory Services†and thereby solving the field level problems faced by the organic farmers/entrepreneurs/startups or other related stakeholders. A 15 days CFA module II was organized at ICAR- Indian Institute of Farming Systems Research, Modipuram, Meerut in two batches with 50 trainees from 15 different states and union territories. In the present study, the learning, knowledge and skill levels of the participants were analyzed. Multiple regression analysis showed that, gender, service experience and serving region significantly affected the learning ability of trainees. There was significant improvement in the knowledge and skill of trainees in various aspects of organic farming, viz. organic standards, certification and marketing network (study area A); technology package (study area B) and general knowledge (study area C). Based on the training effectiveness scores (TES), maximum improvement was observed with general knowledge of organic farming with 103.73% improvement. However, study area A and B exhibited 45.41% and 34.88% improvement, respectively. Further, the success of this inter-organizational training programme could serve as a model for streamlining HRD programmes on organic farming in the country.

Full textAbstract:
WeedSOFT® is a decision support system that was developed to help farmers and consultants in Nebraska with the selection of optimal weed management strategies. WeedSOFT® evolved from HERB, a bioeconomic model for soybean that was developed in North Carolina. The program is composed of four independent modules, namely, ADVISOR, EnviroFX, MapVIEW, and WeedVIEW. ADVISOR helps the user select a treatment based on maximum yield or maximum net gain. EnviroFX and MapVIEW provide environmentally relevant herbicide information and county soil maps that indicate vulnerability to groundwater contamination. WeedVIEW is a visual library of color images and line drawings of 46 common weed species. Over 500 farmers and consultants in Nebraska and adjacent states use WeedSOFT®. As a result of the current regionalization effort, the user base is expected to increase rapidly during the next 2 or 3 yr. This article explains the algorithms implemented in the current version of WeedSOFT®.

Full textAbstract:
A study was conducted in April 2020 to assess the impact and usefulness of agrometeorological Advisory Services in increasing the production of wheat crops under DAMU KVK, Kushinagar. The two villages were selected for this study, and two groups of farmers were selected, namely, a group adopting the agrometeorological Advisories (50 farmers), regularly in their operations (AAS Farmers), and another group of farmers not aware of the agrometeorological Advisories (Non AAS Farmers) during the rabi season. The data were recorded from both the farmer groups, particularly on crop expenditure incurred by the farmers from land preparation to harvest at every stage, and crop growth and yields were observed regularly. The impact assessment was based on feedback that indicated a significant impact in terms of the use of the agrometeorological Advisory Service by farmers. The assessment study indicated that the farmers who adopted agrometeorological advisory services on a real time basis obtained a 28% higher net return in wheat crops compared to Non-AAS farmers who benefited from timely agricultural operations, timely rainfall forecasting, recommended doses of fertilisers, efficient irrigation management, and standard plant protection majors in a required base manner during the crop growing period, as advised in biweekly bulletins. AAS farmers benefited from the timely application of fertilizers, timely and accurate weather forecasting, and timely agricultural operations to obtain a better yield in wheat crop as compared to Non-AAS farmers. Agrometeorological Advisory Services (AAS) might be used to be helpful to the farmers in managing changing weather, resulting in decreased input costs in agriculture and profitable agricultural production by adopting of weather based agrometeorological Advisory.

Full textAbstract:
The United States' National Plant Germplasm System (NPGS) is responsible for the acquisition, preservation, evaluation and distribution of plant genetic resources in the form of seed and clonal germplasm. In order to operate more effectively, the NPGS established a network of 40 Crop Advisory Committees (CACs) to provide analysis, data, and advice about germplasm within a crop or group of related crops of current or future economic importance. CACs are composed of Federal, State and industry scientists representing a variety of agricultural disciplines and geographic areas of importance to the crop. The committees are involved in a variety of activities including: 1) Developing crop descriptors for the collection of standardized characteristic and evaluation data, 2) Determining priorities for germplasm acquisition, evaluation and enhancement, 3) Advising curators on maintenance techniques, and 4) Developing special reports on the status of genetic resources for their crop(s). Twenty-four of the CACs are concerned with horticultural crops.

Full textAbstract:
The Hungarian Chamber of Agriculture (HCA) was established in the spring of 2013 as a public body. The main tasks of the HCA are strengthening and advocacy of domestic agricultural and food sector, supporting the competitiveness of Hungarian food, furthermore the consultancy and delivering fast, accurate and reliable information to farmers. After the integration of village consultants’ network in 2014 the HCA established a unified support system for farmers. This system based on five pillars: information, consulting, training, project management and European Innovation Partnership. In Heves County 27 village consultants and 4 village consultant administrators perform advisory tasks coordinated by the chief village consultants. The scope of official duties performed by the network: crop estimation, data collection and reporting tasks associated with state rating, assessment of damages in agriculture etc. The advisors validate about 9500 farmers’ cards year by year. In our research we examined the main features of the village consultants and farmers receiving services (such as age, gender, level of education, professional experience, current scope of activities and contacts between the two groups). We hypothesized that the age and vocational qualifications of the farmers are determining the number of services used. To answer our research questions we were performed primary data collection in Heves County. We compiled two questionnaires, one for the farmers (N=150) and one for the village consultants (N=18). To answer the remaining outstanding issues we conducted interview-based survey involving 4 experts. In the course of the survey research for the village consultants we examined theirs most important activities and ranked by the number of mention. The five most common cases were the Unified Application Administration, the validation of farmers’ cards, information services in connection with former Agricultural and Rural Development Agency, monitoring data service and Chamber membership fee acknowledgment. The farmers we’ve asked were all familiar with the local village consultant and 88% of them known the office client’s time. The 69% of the respondents more than three times visited the advisor. Based on our research the village consultants completed more than 50% of administrative tasks of farmers in the 70% of cases. Overall, the village consultant network plays an important role in the life of the farmers regardless of age or level of education.

Full textAbstract:
The face of extension and advisory services for agriculture in South Africa has changed significantly in recent years. The focus of government extension services has shifted to emerging farmers, impacting the quality of extension available to commercial farmers. This paper explores the effect of this shift on the sustainability of commercial crop farming in the Eastern Highveld. Three areas of advice and the impact on sustainability were researched, namely soil management, plant nutrition, and crop protection. Crop farmers regard all three as crucial for sustainability and prefer advisors to be knowledgeable in the following order of preference: plant nutrition, soil management, and crop protection. Most farmers are aware of their advisors’ qualifications and accreditations and discount advice by non-accredited and inexperienced advisors. Sustainable advice followed by responsible application is more effective in crop protection than soil management and plant nutrition. Over the past decade, the contribution of qualified advisors through improved decision-making increased yields by upwards of 40%. To maintain a high level of scientific and ethical advice, supply companies should employ qualified agronomists and promote the importance of qualified advice among stakeholders. Advisors should promote an ethical and professional relationship and regularly offer mentorship to qualified but inexperienced advisors.

Full textAbstract:
This paper has taken a 25-horsepower tractor as the object and developed a distributed drive electric tractor (DDET), which may be applied to farms in paddy and upland fields. First, we designed the structure of the chassis drive system in the DDET, then analyzed the dynamic performances, built an evaluation index of dynamic performance for the DDET, and researched the influencing factors of dynamic performances. Moreover, we built the simulation model and studied the dynamic performance based on Advisor software in different working conditions. Finally, we developed the testing tractor of the DDET for test verification. Results show that the traction of DDET is about 5400 N, and the time from being static to being accelerated to a maximum speed of 28.15 km/h is about 5.5279 s. The theoretical analysis results, simulation results, and testing tractor verification results of the DDET designed in this paper are basically consistent, and the overall dynamic performance of the DDET is good.

Full textAbstract:
Conflicts of interests have been hypothesized when agricultural advisory services are connected to agri-input businesses. However, these have not been examined using large sets of advisory service and grower data. We provide quantitative insights into dependencies between service, crop production, sustainability and the level of agri-input business-linkage of extension workers. We analyzed 34,000+ prescription forms (recommendations) issued to growers in China, as well as grower interview data. Results revealed some conflicts of interest, but to a small extent and not always as expected. Both forms of advisory service (with and without business-linkages) heavily emphasize chemical pest management. However, grower interviews revealed that business-linked advisors recommend pesticides even 18% more often than non-business-linked advisors do (96% vs. 78% of advice). This advice was also often implemented (94% and 90% uptake). There is a slightly higher chance that dangerous pesticides are being recommended by business-linked advisors (0.4% vs. 0.14%), but these advisors recommended antibiotics less frequently (1.6% vs. 2.5%). No effects of the source of advice on yields or grower profits were found. Thus, there is no apparent economic disadvantage of growers taking advice from business-linked advisors. However, if pesticide use is a concern for human health and the environment, then the increased use of such products may further exacerbate existing problems. Depending on national priorities, countries may re-consider moving away from governmental extension services, and more closely analyze the advantages of promoting agri-business-linked advisory services (no public funds, better outreach) versus the disadvantages (slightly higher pesticide risks).

Full textAbstract:
Due to the edaphoclimatic conditions in southeast Spain, which are expected to worsen due to climate change, more efficient ways of using water must be found to maintain sustainable agriculture. Due to the current high price of irrigation control systems in southern Europe, 60–80% of soilless crops are still irrigated, based on the experience of the grower or advisor. The hypothesis of this work is that the development of a low-cost, high-performance control system will allow small farmers to improve the efficiency of water use by obtaining better control of soilless crops. The objective of the present study was to design and develop a cost-effective control system for the optimization of soilless crop irrigation after evaluating the three most commonly used irrigation control systems to determine the most efficient. Based on the agronomic results comparing these methods, a prototype of a commercial smart gravimetric tray was developed. The device records the irrigation and drainage volumes and drainage pH and EC. It also offers the possibility of determining the temperature, EC, and humidity of the substrate. This new design is scalable thanks to the use of an implemented data acquisition system called SDB and the development of software in the Codesys programming environment based on function blocks and variable structures. The reduced wiring achieved by the Modbus-RTU communication protocols means the system is cost-effective even with multiple control zones. It is also compatible with any type of fertigation controller through external activation. Its design and features solve the problems in similar systems available on the market at an affordable cost. The idea is to allow farmers to increase their productivity without having to make a large outlay. The impact of this work will make it possible for small-scale farmers to have access to affordable, state-of-the-art technology for soilless irrigation management leading to a considerable improvement in productivity.

The survey was conducted from June 2022 to January 2023 to study the impact of Agro meteorology Advisory Services and to know the increases of production of cotton crops concerning the effect of weather parameters in selected villages under the DAMU project in NTR district, Andhra Pradesh. District Agromet Units (DAMU) which was established in Krishi Vigyan Kendra’s by Andhra Pradesh cooperative program of India Meteorology Department and Indian Council of Agricultural Research. The Main theme of DAMU is to provide timely location specific Agro-met advisories to the farmers at the sub divisional and district level. The agro meteorology advisory services were provided weekly twice among the sub divisions (Tuesday and Friday) and disseminated to farmers by including cotton growers using Whats App, emails and other print media. The impact assessment was based on feedback to come at significant illation in terms of using of Agro meteorology Advisory Service (AAS) by farmers. The assessment study revealed that the farmers who adopted agro advisory services on real-time basis obtained 18 % higher net return in cotton compared to Non-AAS farmers which were benefited by forecasting of rainfall for timely agricultural operations, the recommended dose of fertilizers, and efficient use of pesticides majors in a required support manner during different crop growth stages were advised in bi-weekly bulletins. AAS farmers benefited by timely application of insecticides and fertilizers, timely accurate weather forecasting and timely agricultural operations to gain more yield in cotton crop as compared to Non-AAS farmers. AAS might be used to be helpful to the farmers in managing and changing weather, finally decreased input cost in agriculture and acquiring cost-effective agricultural production by adopting of weather-based Agromet Advisory.

Full textAbstract:
Wide range of inter-annual climatic variability and frequent occurrence of extreme climatic events in Indian context is a great concern. There is a need to assess the impact of these events on agriculture production as well suggest the agri-management options for sustenance. The appropriate region specific agro-advisory needs to be established for the farmers and other stake holders. Crop simulation models are effective tools for assessing the crops’ response to these climate related events and for suggesting suitable adaptation procedures for ensuring higher agricultural production. Remote sensing and GIS are effective tools in this regard to prepare the regional based agro-advisories, by linking with the crop simulation models and relational database layers of bio-physical and socio-economic aspects. For effective agro-advisory services, there is a need to link the other biotic and abiotic stresses for accurate estimates and generating window of suitable agri-management options. Crop simulation models can effectively integrate these stresses for crop and soil processes understanding and ultimate yield formation. In this review article, we have discussed about the inter-annual/ seasonal climatic variability and occurrence of extreme climatic events in India and demonstrated the potential of crop models viz., INFOCROP, WTGROWS, DSSAT to assess the impact of these events (also including climate change) on growth and yield of crops and cropping systems and thereby suggesting appropriate adaptation strategies for sustenance. The potential of remote sensing for crop condition assessment and regional/national yield forecast has been demonstrated. Crop simulation tools coupled with remote sensing inputs through GIS can play an important role in evolving this unique operational platform of designing weather based agro-advisory services for India.

Full textAbstract:
More than 70% of farms in Scarcity Zone of Maharashtra are small and marginal and are thus vulnerable to climate variability. Some factors, such as increased temperatures and longer droughts periods, are likely to depress production. Managing climate risks is a major challenge of today and for the future. To extend the period of forecast for 3-7 days i.e., medium range weather forecast for the benefit of farming, community the India Meteorological Department has been issuing district level medium range forecast to the 127 agrometeorological field units in the country. Under this project apart from weather forecasts, agro-advisories based on weather are also being issued for the benefit of farming community by the AMFU’s. Advisories are farmers bulletin, which take into account the prevailing weather, soil and crop condition, weather forecasts and, suggest measures to minimize the losses (crop or livestock) and effective utilization of inputs (irrigation, fertilizers pesticides etc.,) and also suggest contingent crop planning.The following points are to be kept in mind for preparing effective agro-advisory bulletins:Identification of weather sensitive field operations, Accurate weather forecast taking into cognizance local weather. Real time information on crops (major crops, varieties, sowing time, phonological stage, status of pests and diseases etc.). Reliable source of information .Crop weather calendars, easily understandable language.The feedback is collected from the contact progressive farmers, on usefulness of the advisories as well as suggestions for its improvements. Systemtic study conducted by this unit on economic impact of the project in six villages in Solapur District revealed that there is a benefit of 12- 23% due to adoption of agromet advisories. The contingency plans are needed if following conditions prevail :Failure of south-West Monsoon, Delayed onset or early withdrawal of monsoon, Deficit or erratic rainfall, Damage to crops due to cyclones floods etc. Crop loss due to droughts, Insufficient supply of irrigation water or late release of canal water, Long dry spells, Heat or cold waves, Severe pest or disease outbreaks due to favorable weather conditions.Medium range weather forecast is useful in issuing location specific weather based Agro-advisors to tailor the agricultural operations. By closely monitoring seasonal conditions and using medium range weather forecast an effective contingency cropping strategy is possible. Timely dissemination of these advisories/ contingency crop plans/measures will help the farmers to maximize the yield by optimum use of inputs and enhance the economic returns of the farmers.

Full textAbstract:
Decisions on irrigation water management are usually made at different levels, including farms, water user associations (WUAs), and regional water planning agencies. The latter generally have good access to information and decision tools regarding water resources management. However, these remain out of reach to the final water users, namely the farmers. The study, conducted in the irrigated district of Cherfech, north Tunisia, had the main objective of investigating farmer’s perceptions of, and acceptance for, the use of an irrigation advisory service (IAS) to be implemented by their WUA. The suggested IAS provides the following information: (1) reference evapotranspiration (ETo) and rainfall; (2) crop water requirement (CWR) of the most cultivated crops; (3) irrigation water requirement (IWR) of the farmer’s crop; and (4) crop monitoring and real-time estimation of IWR of crops settled, using soil moisture sensors. Such services and information would be available at the WUA level and provided in a timely manner to farmers for more effective decision making at the plot level. Prior to the acceptance study, we launched a technical study to determine the required tools and equipment required for the implementation of the IAS, followed by a farmer survey to assess their respective perceptions and acceptance towards this IAS. Results showed that only 54% of the farmers are satisfied by WUAs work, but that 77% of them accepted using the suggested IAS. Farmers are also willing to pay for most of the IAS packages suggested. The financial profitability of investing in the IAS at the WUA level shows the venture is financially viable, with a benefit cost ratio (BCR) of 1.018. The project will be even more profitable if we add the social benefits, which may result in water savings at the WUA level.

Full textAbstract:
The production and productivity of different crops are impacted by the weather. Farmers will be better able to prevent crop failure and obtain high yields with greater financial returns if they are aware of real-time weather factors such temperature, relative humidity, wind speed, wind direction, and rainfall. Farmers may better plan agricultural activities, from crop selection to post-harvest handling, by having the proper weather information at the right time. This helps them reduce crop losses. To study the awareness of weather based agro-advisory services, a random sample survey was conducted from 60 farmers from blocks of Andanallur and Musiri block of Tiruchirappalli district and for this study descriptive research design is used. The findings showed that targeting illiterate farmers is far more crucial, and that it is preferable to disseminate weather forecasts in audio or video format to encourage them to adapt their agricultural methods to the weather. The survey revealed that 72.00 per cent of farmers had medium level of awareness, about 95.00 per cent of the farmers check the weather forecast before going for irrigation and pesticide spray, 60.00 per cent farmers are receiving SMS through District Agro-Met Units. Apart from crops, weather forecasts also help with taking care of livestock, which includes animals reared on farms. Just like plants, animals also need the right weather to stay healthy and give good results. This is why accurateweather forecasts matter a lot for both farming and looking after livestocks. Wise use of weather and climate information can help to make better-informed policy, institutional and community decisions that reduce related risks and enhance opportunities, improve the efficient use of limited resources and increase crop, livestock and fisheries production [1]. Our study revealed that the farmers had medium level of awareness. Additionally, awareness needs to be raised so that people understand that in order to increase production and income, weather forecasts must be followed from the time a crop is chosen until harvest.

Full textAbstract:
Aflatoxin in maize and peanuts remains a critical problem in much of Africa and Asia. Many countries in these regions lack a systematic preharvest approach for providing government agencies with warnings of a potential threat to human and animal health resulting from excessive levels of aflatoxin in crops at harvest. This paper sets out an approach to such a system. It is based on the establishment of a surveillance system in each community to monitor aflatoxin contamination resulting from drought stress before harvest and advise on remedial actions. The system should be under the control of a central government coordinator. If severe drought stress occurs, the coordinator would arrange for samples of the affected crop to be provided to a central aflatoxin laboratory established and controlled by the relevant government department. Assays from the central laboratory would be sent via the central coordinator to a government scientific advisory body, which would recommend appropriate remedial action to be taken at government level.

SummaryOrganic farming represents an integral part of agriculture in Austria. The share of organic holdings and the share of area being organically farmed are already high relative to other countries within the European Union. So far, analyses of the organic sector have mainly focused on the economic output and the utilised area; less is known about absolute crop yields per hectare and the gap between organic and conventional crop yields. Given their relevance for profitability calculations and production strategies, such data is of major interest for farmers, advisors, and decision-makers. To address this lack of knowledge, we combine the Austrian farm accountancy data and Integrated Administration and Control System data for Austria. This paper presents a statistical analysis of organic crop yield data for the national Austrian territory as well as for regional categories and covers the period from 2003–2016. The results show a significant difference in crop yields: i) between organic and conventional farming systems; ii) between regional categories in Austria. Organic cereals achieve 35% lower average crop yields than conventional systems, yields for organic root and tuber crops were 27–49% lower. Yield gaps of oilseed and protein crops vary widely between respective crop species.

Good crop yield entirely depends on good management practice and quality management of crops allied with authentic weather forecasting can reduce risk, crop damage, cost of production and increase the yield as well. Bangladesh Rice Research Institute (BRRI) had aimed this study for quantifying the financial benefit of forecasting and validating micro climatological factors and their impacts on paddy production through experimentation and arranging for weather based agro meteorological advisory service delivery to the farmers applying the tools of ICT. A next-generation meso-scale numerical weather prediction system, WRF (Weather Research and Forecasting) model was used for generating atmospheric simulations based on real data (observations, analyses or idealized conditions). Field experiment was conducted in the areas of five different agro microclimatological conditions for Boro rice production, namely; Gazipur, Habiganj, Rajshahi, Barishal and Satkhira. Then the experimental fields were managed according to the weekly management advisory based on weather forecasts. Results obtained suggest that the application of weather predictability accrued a comparative rice yield benefit of 9-12% and a 3–5% reduction in the cost of cultivation. Countrywide application of agro-meteorological advisory service may pave the way for averting adverse climatic effects on agriculture.

<p><strong>Abstract.</strong> The rise in global population has increased food and water demand thereby causing excessive pressure on existing resources. In developing countries with fragmented land holdings there exists constant pressure on available water and land resources. Obtaining field scale crop specific information is challenging task. Advent of open freely available multi-temporal remote sensing observations with improved radiometric resolution the possibilities for near real / real time applications has increased. In this study and an attempt has been made to establish operational model for field level crop growth monitoring using integrated approach of crowd sourcing and time series of remote sensing observations. The time series of Sentinel 2 (A and B) satellite has been used to estimate crop growth related components such as vegetation indices and crop growth stage and crop phenology. In initial stage high valued cereal crop Wheat has been selected. The field level information (i.e. 108 Wheat fields) collected using mobile based agro-advisory platform mKRISHI&amp;reg; has been used to extract time series of Sentinel 2 observations (44 scenes for year 2016 and 2018). The moving average has been used for filling gaps in the time series of vegetation indices. The BFAST and GreenBrown package in R were used for detecting breaks in vegetation index time series and estimating crop growth stages. Analysis shows that the estimated crop phenology parameters were in better agreement with the field observations. In future more crops from different agro-climatic conditions will be considered for providing field level crop management advisory.</p>

Full textAbstract:
Many pests damage pea crops, which potentially leads to reduced quality and yield losses. Since pests occur at different phenological growth stages of pea crops, the prediction of growth stages, for example as BBCH stages, is beneficial. In this study, three models have been developed to simulate growth stages of grain and green pea crops, for the latter with early and late sowing dates. All data, such as BBCH stages and air temperature, were collected in Germany in a three-year study under practical farming conditions at 415 sample sites. For the development of each model, a Gompertz regression model based on the observed data was performed. The model validation suggests that each model precisely and reliably predicts pea crop growth stages for spring-sown peas. Amongst others, the RMSEIndex for grain peas was 3.4; for green peas, early and late sowing dates, respectively, they were 3.4 and 4.5. SIMONTO-Pea (SIMulation of ONTOgenesis) is the first model that predicts detailed pea crop growth stages based on the BBCH scale. This innovation is especially beneficial for users such as advisors and farmers dealing with spring-sown pea crops as a decision support system in monitoring and pest management according to pea crop growth stages.

Full textAbstract:
Giant ragweed has been increasing as a major weed of row crops in the last 30 yr, but quantitative data regarding its pattern and mechanisms of spread in crop fields are lacking. To address this gap, we conducted a Web-based survey of certified crop advisors in the U.S. Corn Belt and Ontario, Canada. Participants were asked questions regarding giant ragweed and crop production practices for the county of their choice. Responses were mapped and correlation analyses were conducted among the responses to determine factors associated with giant ragweed populations. Respondents rated giant ragweed as the most or one of the most difficult weeds to manage in 45% of 421 U.S. counties responding, and 57% of responding counties reported giant ragweed populations with herbicide resistance to acetolactate synthase inhibitors, glyphosate, or both herbicides. Results suggest that giant ragweed is increasing in crop fields outward from the east-central U.S. Corn Belt in most directions. Crop production practices associated with giant ragweed populations included minimum tillage, continuous soybean, and multiple-application herbicide programs; ecological factors included giant ragweed presence in noncrop edge habitats, early and prolonged emergence, and presence of the seed-burying common earthworm in crop fields. Managing giant ragweed in noncrop areas could reduce giant ragweed migration from noncrop habitats into crop fields and slow its spread. Where giant ragweed is already established in crop fields, including a more diverse combination of crop species, tillage practices, and herbicide sites of action will be critical to reduce populations, disrupt emergence patterns, and select against herbicide-resistant giant ragweed genotypes. Incorporation of a cereal grain into the crop rotation may help suppress early giant ragweed emergence and provide chemical or mechanical control options for late-emerging giant ragweed.

Ethiopia’s government has created a number of policies and programs to address the urgent issue of rising food prices. Extension and regulation initiatives aiming at influencing the production and marketing are frequently used in conjunction with them. However, lack of indices on relative importance of individual crops results poor policy outcomes. Analyzing household decision dynamics and how household decisions respond to policies is crucial to reduce persistent complaints from recipients and avoid negative policy outcomes. For this study, data from 392 randomly chosen households of Kewot woreda was used. Sorghum found with higher calorie index per profit while mung bean was found higher profit index. Crop diversification found inefficient that arise from profitability differences and return to scale. Additionally multiple objectives could be met using tradeoffs among different crop benefits. This study also summarizes major findings from previous crop-related policies and linked them to specific crop characteristics. It is advised that policies be adjusted to reflect the value, character, and utility of crops.

In the contemporary agricultural landscape, agriculture faces four pressing demands: competitiveness, ensuring food security for a growing population, environmental sustainability, and providing farmers with acceptable living conditions. To meet this global challenge, digital technologies represent a major avenue for innovation and development towards modernized digital agriculture. In this context, irrigation advisory platforms have proven to be transformational tools for both farmers and policymakers, offering insights into the appropriate crop water requirements. This article presents a benchmarking analysis of around 20 professional irrigation advisory platforms. The methodology involves selecting 20 platforms based on accessibility ensuring geographical characteristic diversity. Our findings highlight key criteria shaping the ecosystem of such platforms, including the services offered and their objectives, the types of covered crops, the target users, the form, as well as the source, the availability of the platform, and the variety of data utilized. Lastly, we discuss the main conclusions drawn from our analysis and provide insights into the challenges and future perspectives of irrigation advisory platforms in enhancing agricultural practices and sustainability.

Expert systems (ES) technology has many existing and potential uses as input into the agricultural production process. ES are simply computer programs that attempt to emulate human expertise for problem solving purposes. This technology is well suited to agricultural problem solving because of its ability to encode existing knowledge within specific application areas and then apply this knowledge within the problem solving process. ES effectively leverage management's input into agricultural production systems by allowing for the assimilation of all available knowledge pertinent to the task at hand. There are many types of agricultural ES and these can generally be categorized into: Crop Management Advisors, Livestock Management Advisors, Planning Systems, Pest Management Sytems, Diagnostic Systems, Conser-vation/Engineering Systems, Process Control Systems and Marketing Advisory Systems. The cost of ES development can be high. Potential projects, therefore, should be subjected to a benefit/cost analysis to ensure that development efforts are well targeted. ES development and agricultural research are complementary processes and should become more coordinated within an integrated knowledge production and implementation cycle. Key words: Expert systems, knowledge, management, agriculture, research

Abstract: In developing nations like India, where more than 33% of the population is in need, ensuring food profitability is a major problem. Estimates of crop yields for a given season are indisputably regarded as making a substantial contribution to investigating food accounting data and yield deficits. There is no structure in place to advise farmers on the best crops to cultivate, which would help with cost estimation. So, in this paper, we make an effort to forecast crop prices that a farmer can get from his field by looking at trends in historical data. For our analysis, we are taking a few crops like wheat, ragi, bajra, and barley. We are using a variety of information, including rainfall, previous crop yields, etc. We have implemented supervised machine learning algorithms (Decision Tree) to analyze and predict data.

Full textAbstract:
Global warming by 2 °C or above will frequently see weather beyond the critical tolerance threshold for agricultural extreme high temperatures. If so, people will have to more accurately evaluate the opportunities and risks posed by future climate change while adjusting the structure of agricultural production. However, accurate assessment results of the impacts of climate change on crop yield are absent in the current studies on the impact of climate change on the agricultural economy. To address this gap, this paper sets forth a comprehensive evaluation method using a crop model coupled with a computable general equilibrium model. According to research findings, future climate change may continue with the trend of the continued decline of grain planting areas and the continued growth of cash crop planting areas in ecologically vulnerable regions. This will make grain security more difficult. On one hand, perennial crop planting broadens the eco-space for future economic and social development in ecologically vulnerable regions. Therefore, attention should be paid to grain security. The cash crop planting area should not be excessively expanded. On the other hand, it is advised to plant perennial crops in those areas which are unsuitable for planting cash crops.

Full textAbstract:
To meet the sustainable development goals in rocky desertified regions like Guizhou Province in China, we should maximize the crop yield with minimal environmental costs. In this study, we first calculated the yield gap for 6 main crop species in Guizhou Province and evaluated the quantitative relationships between crop yield and influencing variables utilizing ensembled artificial neural networks. We also tested the influence of adjusting the quantity of local fertilization and irrigation on crop production in Guizhou Province. Results showed that the total yield of the selected crops had, on average, reached over 72.5% of the theoretical maximum yield. Increasing irrigation tended to be more consistently effective at increasing crop yield than additional fertilization. Conversely, appropriate reduction of fertilization may even benefit crop yield in some regions, simultaneously resulting in significantly higher fertilization efficiency with lower residuals in the environment. The total positive impact of continuous intensification of irrigation and fertilization on most crop species was limited. Therefore, local stakeholders are advised to consider other agricultural management measures to improve crop yield in this region.

This paper presents a review of the plant parasitic nematodes that are of concern in New Brunswick, Nova Scotia, and Prince-Edward-Island, and the approaches used to manage them. The root lesion nematode (Pratylenchus penetrans) is the only nematode species in the region that regularly reduces crop yields. The northern root-knot nematode (Meloidogyne hapla) occasionally causes damage to carrots (Daucus carota), but population levels of this nematode species usually are very low. The clover cyst nematode (Heterodera trifolii) is widespread, but has not caused any damage to crops in the region. Management procedures used to reduce the impact of plant parasitic nematodes in the Maritime provinces, e.g. crop rotations, nematicide treatments, enforcement of quarantine regulations, and tillage practices are discussed. A nematode advisory service is also considered.

The groundwater irrigation, catering to more than 60 per cent of total irrigation in India, has significantly contributed to food grains production. Participatory irrigation management programme has been implemented transferring irrigation management to WUAs. Present study was undertaken during 2019 to explore cropping scenario in groundwater irrigation command under jurisdiction of WUAs in Burdwan district of West Bengal covering a random sample of 120 farmers. It is revealed that paddy was the major crop in both kharif and summer season. During rabi season, potato was grown in larger areas followed by mustard. While all 120 farmers had grown paddy as single crop in kharif season, 100 and 82 farmers have cultivated potato and mustard in rabi season and 75 farmers have grown boro rice during summer season. Cultivated land utilization index value was more than 50 per cent. Crop diversity index (CDI) value of 36 per cent showed lack of crop diversification in groundwater irrigation command areas that warrants need of bringing more areas under different crops. Multiple cropping index of 176 per cent showed a higher cropping intensity in groundwater irrigation command. Thus, Extension advisory services need to promote crop diversification in groundwater irrigation command areas through proper crop planning and capacity building of WUAs.

Study was conducted to explore the role of extension advisory services in relation to smart agriculture to mitigate the effect of climate. Agriculture is a very prominent sector of the Indian economy accounts for (49%) of the employment and one-sixth of the GDP. The agricultural industry is supported by 500 million small holder farms. Agriculture is extremely vulnerable for climate change and water as well. Climate change affects agriculture in the Asia and Pacific region particularly in those areas that are vulnerable to natural disasters. Higher temperature reduce yield of desirable crops while encouraging weeds and pests proliferation. Changes in precipitation pattern and floods affect agriculture causing crop failures. In India, significant negative impacts occurred due to climate change reasoned to reducing the yields. In addition to advisory services advanced information on likelihood of weather help to carry out to proper management of resources for agricultural operations to minimize the risk and facilitate growth and realizes the optimum crop yield. Further, decentralization of extension services tracing the different state or district-level funding is needing exercise not always known at national level in various states or provinces spending on extension service. It plays a prominent role by creating awareness regarding adaptation of best practices regarding climate change, deforestation and planting of trees also potential to transform the vision of India’s famers about food security, poverty alleviation and sudden climatic threats. Thus, the advisory services help taking the advantage of benevolent weather and minimize adverse impact of malevolent weather.

Aim of study: Root-knot nematodes are considered a common limiting factor to reaching premium quality and economically viable yields in horticultural crops. Soil disinfestation with agrochemical fumigants has been the main nematode control method until their recent ban due to environmental and social concerns. This paper explores farmers and agricultural advisors’ opinion and preferences on the sustainable use of available nematode control methods, considering sustainability as an integration of nematicidal effectiveness, reduction of environmental harmful effects and preservation of human health.
 Area of study: This study has been carried out between farm advisors of intensive horticultural crop areas in Southern Spain.
 Material and methods: Farm advisors’ opinion and preferences on the use of nematicides was evaluated following an opinion survey and the Analytic Hierarchy Process (AHP) method. The analysis done was exploratory.
 Main results: Providing that current available control methods give enough nematicidal effectiveness to get a profitable yield, the group of farm advisors showed a great consciousness on the use of sustainable alternatives for nematode control in intensive horticultural crops, prioritizing biosolarization as the first option, followed by biopesticides and fumigant nematicides in third place. The use of ozone and non-fumigant nematicides with high toxicity profiles were considered the last options, but new generation nematicides with lower ecotoxicity profiles are also considered as an important tool in sustainable nematode management.
 Research highlights: These results provide a prediction of farmers' responses to the sustainable use of nematicides promoted by the European Union when agrochemical fumigants are banned.

India Meteorological Department (IMD), Ministry of Earth Sciences (MoES) in collaboration with Indian Council of Agriculture Research (ICAR), State Agriculture Universities (SAUs) , Indian Institute of Technology (IITs) and other organizations is rendering weather forecast based District level Agrometeorological Advisory Service (AAS) for benefits of farmers in the country under the centrally sponsored scheme ‘Atmosphere & Climate Research-Modelling Observing Systems & Services (ACROSS) ’ of MOES. AAS, popularly known as Gramin Krishi Mausam Sewa (GKMS) provides advance weather information along, with crop specific agromet advisories to the farming community by using state of the art instruments and technology through efficient delivering mechanism of the information which ultimately enables farmers to take appropriate actions at farm level. The various components of GKMS viz. observing weather, its monitoring and forecast; crop specific advisory bulletin generation and dissemination; outreach and feedback have been/are being digitized to support integrating all the components of information generation and action suggested linked to these information. An Information and Communication Technology (ICT) based Agromet Decision Support System is developed for automation of the services provided under GKMS. This includes a dynamic framework to link the information of weather forecast, real time weather observation, crop-weather calendar etc. to translate weather forecast into actionable farm advisories for efficient farm level decision making in India. Apart from this, effort is being made to develop recent technology driven tools to estimate future yield of crops and prepare an irrigation schedule without a need of multiple parameters.

Full textAbstract:
Various regression equations based on weed density alone, or relative time of weed and crop emergence or crop density in addition to weed density have been developed in western Canada to estimate the effects of wild oat (Avena fatua L.) and volunteer cereals on yield loss of field crops, and to advise farmers on the economics of weed control with herbicides. In 1997, 1998, and 1999, several of these equations were evaluated in 9 barley (Hordeum vulgare L.), 9 wheat (Triticum aestivum L.) and 11 canola (Brassica napus L.) fields in Alberta. Wild oat was the dominant weed in the barley and wheat fields, and wild oat or volunteer cereals in the canola fields. In barley and wheat, more complex equations based on both weed density and either crop density or relative time of weed and crop emergence were more reliable in estimating yield losses due to wild oat than those based on weed density alone. In canola, an equation based on volunteer barley and canola density provided the most reliable estimates. Under the assumed crop prices and herbicide costs, these equations also resulted in the best estimates of whether or not a herbicide application resulted in a net profit or loss. Herbicide application was rarely economical in barley, but usually economical in wheat and canola reflecting the different market value of the crops. The implementation of the weed economic threshold concept is likely to be more feasible in low-value crops such as feed barley than in higher-value crops such as canola. Key words: Barley (Hordeum vulgare L.), canola (Brassica napus L.), volunteer cereals, weed economic threshold, wheat (Triticum aestivum L.), wild oat (Avena fatua L.)

Full textAbstract:
The number and status of germplasm collections associated with plant breeding and applied genetics programs at U.S. public sector institutions [i.e., at both state (SAES) and federal (USDA ARS) agricultural experiment stations] was assessed from a resource conservation perspective via a questionnaire sent to over 1300 people who have been involved with the use or conservation of crop genetic resources in research, preservation, administration, or advisory capacities. The latter so-called working collections typically emphasize use rather than conservation of germplasm, while in turn preservation is one of the primary functions of genebank collections such as those managed by USDA's National Plant Germplasm System. A major objective of the project was to assess the vulnerability of germplasm in working collections to being discarded or left in limbo when breeding programs are discontinued. An evaluation was made of “who is breeding or conserving what crops and where” in order to determine patterns of investment in genetic improvement of major vs. minor crops, as well as in federal- vs. state-based activities. Such differences may be relevant when devising plans to improve germplasm conservation and use. Specific examples of breeding and conservation activity relating to vegetable crops will be compared to that of other types of crop commodities.
