Abstract:

AbstractMeloidogyne graminicola, the rice root-knot nematode, has become a constraint on Asian rice production due to rice cropping intensification and increasing scarcity of water. This work relates to the assessment of crop rotation, fallow and nematicide treatments in naturally infested fields to manage M. graminicola populations and prevent yield losses. One or two consecutive crops of cowpea or seasons of fallow before a rice crop lowered nematode populations and improved rice yield by 30-80%. Methyl bromide was used to determine yield potential and almost eradicated the nematode, trebling rice yield. Carbofuran improved yield of the first rice crop but did not affect the second rice crop. Due to its short life cycle, M. graminicola populations were similar after only a single rice crop and after three consecutive crops. It is recommended that, to ensure higher rice yields, M. graminicola populations should be maintained at low density by non-host crop rotations or fallows, ideally for two seasons before planting rice.

Abstract:

Application of crop simulation models at larger spatial scales is very essential to develop best management practices in order to maximize yields and reduce environmental pollution. In the present study, spatial analysis of long- term simulations were carried out with DSSAT spatial analysis tool linked with GIS to estimate irrigation requirements and nitrate leaching under alternate rice establishment methods in the Wargal watershed, Andhra Pradesh, India. Rice yields were compared among three management scenarios: rainfed, aerobic and flooded systems. Grain yield, seasonal water balance components, nitrate leaching and water use efficiency were calculated, visualized and mapped with GIS. The rice productivity increased by 22% and 27% under aerobic and flooded management compared to rainfed rice. The adoption of new water efficient aerobic rice cultivation in the watershed resulted in 36% water saving with a relatively small yield reduction of 4%, thus increasing the water productivity to 0.77 g kg-1 in aerobic compared to 0.56 g kg-1 in flooded rice. The aerobic rice method reduced the overall water pumping hours to 88 h ha-1 during rice crop season compared to 299 h ha-1 with flooded rice cultivation, resulting in 71% energy savings.

Abstract:

A field experiment was conducted at Rice Research Station, Kayamkulam, Alappuzha in Kerala to assess the impact of integrated nutrient management (INM) on four rice (Oryza sativa L.)-based cropping systems, compris- ing rice during the rainy (kharifj and winter (rabi) seasons; and four different crops during the summer season, in terms of their productivity, effect on the organic carbon of soil and nitrogen balance. Inclusion of legumes in the cropping system and integrated nutrient management improved the organic carbon status of the soil. The crop sequences rice-rice-cowpea [Vigna unguiculata (L.) Walp.] and rice-rice-groundnut (Arachis hypogaea L.) showed a positive nitrogen balance in the soil, the maximum being after rice-rice-groundnut crop sequence. The crop sequences rice-rice-sesame (Sesamum indicum L.) and rice-rice-okra (Abelmoschus esculentus L.) re- duced the available nitrogen status of the soil. Integration of nutrient sources made the predominant rice-rice- sesame cropping sequence more productive in the sandy-loam soil. Inclusion of groundnut and cowpea in rice- based crop sequences increased the yield of the succeeding crop of rice.

Abstract:

Efficient use of nitrogen (N) fertilizer is critically important for China’s food security and sustainable development. Crop models have been widely used to analyze yield variability, assist in N prescriptions, and determine optimum N rates. The objectives of this study were to use the CERES-Rice model to simulate the N response of different high-latitude, adapted flooded rice varieties to different types of weather seasons, and to explore different optimum rice N management strategies with the combinations of rice varieties and types of weather seasons. Field experiments conducted for five N rates and three varieties in Northeast China during 2011–2016 were used to calibrate and evaluate the CERES-Rice model. Historical weather data (1960–2014) were classified into three weather types (cool/normal/warm) based on cumulative growing degree days during the normal growing season for rice. After calibrating the CERES-Rice model for three varieties and five N rates, the model gave good simulations for evaluation seasons for top weight (R2 ≥ 0.96), leaf area index (R2 ≥ 0.64), yield (R2 ≥ 0.71), and plant N uptake (R2 ≥ 0.83). The simulated optimum N rates for the combinations of varieties and weather types ranged from 91 to 119 kg N ha−1 over 55 seasons of weather data and were in agreement with the reported values of the region. Five different N management strategies were evaluated based on farmer practice, regional optimum N rates, and optimum N rates simulated for different combinations of varieties and weather season types over 20 seasons of weather data. The simulated optimum N rate, marginal net return, and N partial factor productivity were sensitive to both variety and type of weather year. Based on the simulations, climate warming would favor the selection of the 12-leaf variety, Longjing 21, which would produce higher yield and marginal returns than the 11-leaf varieties under all the management strategies evaluated. The 12-leaf variety with a longer growing season and higher yield potential would require higher N rates than the 11-leaf varieties. In summary, under warm weather conditions, all the rice varieties would produce higher yield, and thus require higher rates of N fertilizers. Based on simulation results using the past 20 years of weather data, variety-specific N management was a practical strategy to improve N management and N partial factor productivity compared with farmer practice and regional optimum N management in the study region. The CERES-Rice crop growth model can be a useful tool to help farmers select suitable precision N management strategies to improve N-use efficiency and economic returns.

Abstract:

Wheat is an important economic crop and major staple food all over the world including Pakistan. Among rice pests, the rice pink stem borer (Sesamia inferens Walker) has been reported on wheat crop for the last many years resulting in whiteheads in the wheat crop. This study was planned to determine the effect of rice straw management on the incidence of S. inferens on wheat crop in the rice-wheat cropping pattern of Multan, Punjab. There were five treatments including wheat sowing on non-rice field, zero tillage after burning rice stubbles, zero tillage without burning rice stubbles, rotavator after burning rice stubbles, and rotavator without burning rice stubbles. The results revealed that the maximum number of tillers/m2 (708) was produced in zero tillage after burning rice stubbles. The maximum incidence (1.75%) of S. inferens was observed in zero tillage without burning rice stubbles. In conclusion, the appropriate management of rice stubbles has an important role in the management of S. inferens in the wheat crop. The results proved that using a rotavator as a tillage tool before the sowing of the wheat crop has remarkably reduced the incidence of S. inferens. The burning of stubbles was statistically at par with zero tillage with the highest infestation and environmentally hazardous. Therefore, the destruction of rice stubbles through rotavator is the most effective tool against S. inferens.

Abstract:

Rice, a key staple food crop in the world and India, offers food and nutrition security to millions of the global population. Abiotic (water, soil, atmospheric) stresses affect yield and quality of rice. This necessitates stress-resilient rice production technologies sufficiently fortified by novel stress mitigation and adaptation strategies. Recent crop improvement strategy has partially managed to resolve the challenges presented by abiotic stresses such as high temperature, drought, salinity, alkalinity, waterlogging and mineral deficiency. The complication and multiplicity of abiotic stresses necessitate the use of extensive, integrative and multi-disciplinary techniques to achieve resilience. Crop improvement, along with the agronomic interventions, is essential to stabilise the productivity and profitability of rice production. This article gives an overview of the potential impacts of abiotic stress on rice and suggests the adaptation and mitigation strategies.

Abstract:

Two experiments were conducted at Chalan Beel (Experiment-1: Sirajgonj) and at Monglar Beel (Experiment-2: Faridpur) to improve the rice-based cropping system in the lowlands during 2021 - 2022. Treatments of Experiment 1 were four cropping patterns, T1 = Mustard-Boro rice, T2 = Mustard-Jute, T3 = Potato-Boro rice, and T4 = Fallow-Boro rice. Treatments of Experiment 2 were four cropping patterns viz. T1 = Onion-Jute, T2 = Onion-Broadcast aman (B. aman) rice, T3 = Lathyrus- B. aman rice and T4 = Fallow-Boro rice. Experiments were conducted in an RCB design with five dispersed replications. Crops in the patterns were sown/planted/transplanted timely in the growing season. Cultural management was done as and when necessary as per the recommendation of each crop. All relevant data was collected and analyzed systematically. The results of Experiment 1 revealed that Mustard-Jute and Potato-Boro rice cropping patterns were found to be superior in respect of productivity and economic returns as compared to existing cropping patterns (ie. Fallow-Boro rice cropping pattern). The findings of Experiment 2 indicated that Onion-Jute and Onion-B. aman rice were found as the most productive cropping pattern with better economic benefits over existing cropping patterns (i.e. Fallow-Boro rice cropping pattern). Farmers are interested to adopt in these improved cropping patterns in the beel area. They will get more economic returns. The total food production of the country will be enhanced through the adoption of these improved cropping patterns.

Abstract:

Ratoon rice, a unique method of cultivating a second crop from primary harvested stubble, is gaining recognition for its potential to revolutionize rice production sustainability and resource efficiency. This comprehensive study aimed to assess the effectiveness of ratoon rice cropping systems compared to traditional methods, focusing on grain yield, quality, economics, and overall sustainability. To achieve better yields in ratoon crops, it is crucial to adopt suitable management practices for both the main crop and the ratoon crop. These practices encompass land preparation, use of suitable cultivars, water management, precise fertilizer application, appropriate cutting stubble height, and effective control of insects and diseases. Results unveiled that with proper management, ratoon rice yields were on par with approximately 60% of the main crop while utilizing only 50% of the labor and resources. The ratoon rice system demonstrated multiple benefits, including farmer profitability, improved crop quality, and reduced greenhouse gas emissions. Despite its promising potential, the widespread adoption of ratoon rice faced limitations such as inconsistent and lower ratoon crop yields, and the lack of suitable cultivars and specialized rice mechanical harvesters. Addressing these challenges, critical agronomic practices were identified, encompassing nutrient and water management, stubble cutting height, variety selection, and integrated technologies for disease and insect control. Ratoon rice is crucial for promoting widespread adoption and securing ratoon rice as a viable solution for the future of rice cultivation.

Abstract:

Rice is a primary staple food for a large portion of the world's population, and the rice crop is also one of the major consumers of fresh water resources. The conventional method of rice cultivation, i.e., manual transplantation, poses significant environmental challenges and is increasingly deemed economically unviable. Researchers from various countries have been actively exploring alternative rice production methods to address this concern while safeguarding food security. One such method is Direct Seeded Rice (DSR), which has gained popularity and adoption in different regions worldwide. This method offers potential benefits, such as reducing water usage, lowering labour costs, and improving soil health. Additionally, DSR facilitates faster crop establishment and promotes timely sowing, which is particularly beneficial in regions facing labour shortages or unpredictable monsoon patterns. Furthermore, it reduces methane emissions, making it an environmentally sustainable choice. However, its adoption also presents challenges, including weed management, uneven crop establishment, and precise water and nutrient management. A critical review underscores the crucial differences between these rice cultivation methods by shedding light on their environmental and economic impacts. This review identifies best practices for DSR cultivation, addresses common challenges, and proposes actionable solutions to enhance sustainability and scalability. It emphasizes the importance of farmer education and policy support to ensure widespread and effective implementation of DSR practices..

Abstract:

Rice (Oryza sativa L.) is the most important food crop cultivated in India with the average productivity of 2.9 t/ha. Rice has the largest yield potential crop which is to be tapped with sound management technologies like appropriate nutrient management techniques along with adoption of system rice intensification. To sustain present food sufficiency and to meet future food requirements, India has to realize an annual growth rate of at least 3% in productivity of rice. To maintain the nutritional standards, fertilizer nutrients should be applied in balanced and required proportion. Among the different nutritional elements, nitrogen (N) has received prime attention both by the farmers and researchers. Relationship among the growth, yield and nitrogen utilization in rice are becoming increasingly understood at the physiological and molecular level. Moreover, time and method of nitrogen application play a crucial role in increasing efficiency of fertilizers as well as the productivity of rice. This review paper attempts to document the different sources of nitrogen and its effect on growth and productivity of rice under system rice intensification.

Abstract:

Rice is the staple food of nearly half of the world's population, most of whom live in Asia. For intensive, high-yielding rice production, access to irrigation water and drainage facilities is crucial. Provision of irrigation facilities expanded rapidly in the 1970's and early 1980's in the major rice-producing countries of Asia, but the management of water has remained inefficient. Investments in new irrigation have declined as the rice supply improved and the development of new water resources became increasingly costly. This trend is not likely to be reversed in the foreseeable future. Consequently, improved efficiency in the use of water is needed to maintain rice production growth.

Abstract:

Weeds are unwanted and undesirable plants that interfere with cultivated crops for utilization of natural resources such as nutrients, water, and light, space, causing harbor of insect pests and disease adverse allelopathic effects and increasing cost of production indirectly, reducing crop yield. India is an agrarian country, where cropping systems form the backbone of Indian agriculture. Every cropping system has its associated weeds, and to manage these weeds requires a specific crop management approach. The main rice-based cropping systems in India, such as rice-wheat, rice-rice, rice-pulse, rice-maize, and rice-oilseed, have been pivotal in ensuring food security. However, these systems face significant challenges due to weed infestations, leading to yield losses ranging from 13% to 97%. Weeds like grass, sedge and broad-leaf weed varieties pose a substantial threat to these crops, particularly in direct-seeded conditions. To manage weeds effectively, various approaches are employed, including crop rotation, tillage, herbicide application, and intercropping. For instance, in rice-wheat systems, zero-tillage practices, crop residue mulch, and early sowing help to reduce weed emergence. In rice-pulse systems, pre-emergence herbicides, hand weeding, and intercropping prove effective. Maize-based systems benefit from tillage, mulching, and planting at closer spacing. Weed management is critical to sustaining rice-based cropping systems and ensuring food security in India. Tailored strategies that consider crop-specific challenges are essential to mitigate yield losses and maintain agricultural productivity.

Abstract:

After the harvest of crop, the disposal of the rice stubbles remains a notable area of interest in all the growing areas of rice. The present review paper explores and highlights an effective strategy of decomposing the decomposers of the paddy stubble. Due to the increasing production of rice, there is an increase in rice crop residues and stubbles production. Conventional methods of management of paddy involve burning, surface retention, mulching, bailing, incorporation/amalgamation and direct removal. However, there are certain environmental challenges by using available agricultural implements. Thus, this current study demonstrates strategic management of the paddy crop residue for a sustainable environment. The developed eco-friendly methods will render new dimensions for the application of the post harvested residues. The review paper will be significant for sustainable management of the wastes of the paddy crop and hence strategic decomposition method, which will be beneficial for the society, farmers as well as the environment

Abstract:

To investigate the effect of different plant residues on weed inhibition and yield of transplant aman rice, an experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh during June 2017 to December, 2017. The experiment comprised of three rice cultivars i.e. BR11, BRRI dhan34 and BRRI dhan49 and five different plant residues treatment viz., no crop residues (control), soybean, wheat, bishkatali and sorghum crop residues @ 2.0 t ha-1 of each. The experiment was laid out following randomized complete block design with three replications. Weed population and weed dry weight were significantly affected by cultivars and crop residues treatment. The highest percent inhibition of 58.31%, 46.84%, 66.85%, 66.94% and 57.6% was in Panikachu (Monochoria vaginalis), Shama (Echinochloa crusgalli), Chesra (Scirpus juncoides), Sabujnakful (Cyperus difformis) and Amrul (Oxalis corniculata), respectively caused by sorghum crop residues. The grain yield, as well as the yield contributing characters produced by BR11,was the highest among the studied varieties. The highest number of effective tillers hill-1 (8.41), number of grains panicle-1(118.08) and 1000-grain weight (20.54 g) were observed in sorghum crop residues. BR11 under sorghum crop residues @ 2.0 t ha-1 produced the highest grain (5.76 t ha-1) and straw yield (6.39 t ha-1). So, to reduce herbicide use in the present situation of Bangladesh, natural herbicide or crop residues like sorghum might be used as an alternative way for weed management for effective and sustainable rice production.

Abstract:

The Indo Gangetic Plane (IGP) is an important region located in South Asia blessed with fertile agricultural farmlands and a diverse ecosystem. Rice-Wheat (RW) cropping system is predominant in the Indian region of the IGP. Almost complete rice area harvesting is performed with combine harvester which leave huge chunk of loose straw. Rice residues are often burned because managing of huge amount of straw in short window period is difficult task. Moreover, the loose straw hinders tillage and seeding operations for the following crop. Retaining crop residues in the field can replenish soil nutrient stocks and organic matter, contributing to sustainable RW production. Therefore, different seeders are available to sow wheat into the rice stubble field which avoids the burning of crop residue as well as several tillage operations to manage the residue. Machinery like Happy seeder, zero till drill, spatial till drill, smart seeder and super seeder gaining popularity among the farmers for timely sowing of the wheat under rice stubble condition. Use of Super Straw Management System (Super SMS) is the pre-requisite for the smooth operation of above said direct seeding machines. However, the adoptions of these technologies are still not up to desired levels due to lack of knowledge and higher cost of the machinery.

Abstract:

Rice cultivation in Pakistan is important for local food security and international trade, especially through export of popular brands like Kernel and Super Basmati. However, the industry faces significant challenges from various biotic and abiotic stresses, including leaf blight (BLB) caused by Thomonas oryzae PV. which can cause decline. The prevalence of BLB is increasing in Pakistan, affecting weak Basmati varieties and causing up to 30% crop failure, especially when the disease occurs during the critical growth period. This disease and others like bacterial infection caused by Burkholderia glumae, demonstrate the interaction between bacteria, climate change (such as temperature and humidity) and genetics. MAS promote Plant Growth-Promoting Rhizobacteria (PGPR) which are medicinal and antibacterial. Extensive research has identified several genes (R genes) against BLB such as XA1, XA21 and XA7, which have been successfully incorporated into various rice varieties to enhance disease resistance. Genetic modification, although promising for rapid incorporation of protective genes, requires careful monitoring to ensure safety and efficacy across generations. Crop production, and entrance screening, including in wild rice, also play an important role in identifying emerging sources of disease resistance. Future research will focus on developing these technologies to improve crop production and disease resistance, thereby protecting food security in Pakistan and beyond.

Abstract:

This article provides information about the crop residue management present in rice-wheat cropping system in China and Indian Subcontinent. It focuses on the importance of sustainable crop residue management for environmental conservation, crop productivity and health risk mitigation. The study brings attention to what is usually viewed as residue has value, it stresses on the importance of converting residue to enhance soil fertility and to fulfill crop nutrient requirements. The incorporation of wheat and rice residues into the soil is shown to support sustainable crop production and increases soil organic matter and nutrient levels. On the other hand, combusting these residues results in environmental pollution, various health hazards and reduction of valuable nutrients. There are several ways for rice straw management, some of which are discussed here i.e., off-farm composting and <em>in-situ</em> incorporation. Although these methods have advantages, they are also laborious and time consuming. These limitations are solved by innovative methods such as the Turbo Happy Seeder. Moreover, the article emphasizes the necessity for farmers to shift from burning residues (which causes several hazards) to eco-friendly alternatives backed up by financial incentives and technological innovations. It addresses the potential of biochar, a carbon-rich byproduct produced due to biomass pyrolysis, for improving soil quality and lowering emissions of greenhouse gases. Biochar has the capacity to retain nutrients and water due to which it is regarded as a valuable soil amendment that enhances soil quality. It also emphasizes the efficiency of energy conversion in thermal processes using rice straw as biomass feedstock, which contributes to sustainable energy generation source. In conclusion, it stresses the role of rice straw management in fortifying soil fertility and ensuring agricultural sustainability within rice-based cropping systems. Managing the residue not only helps farmers but also helps in resource preservation and environmental protection. © 2022 The Author(s)

Abstract:

Rice (Oryza sativa L.) is one of the most significant cereal in the world. Globally, the top rice producing country is China, while India is the world’s second largest producer and the largest exporter of rice in the world. It covers one-third of the total cultivated area in India as it is one of the major staple food crops. The application of nitrogenous fertilizer in crop production system is an important aspect of modern crop management practices and one of the determining factors to increase crop yield and thereby keeping pace with the expanding human population. Rice production can be increased by the application of nitrogenous fertilizer whether organic or inorganic at an appropriate time and place. The fertilizer should be applied in multiple split doses depending on the soil’s nutritional status, crop demand and the sources of nutrients. However, most of the nitrogenous fertilizer applied to rice fields is not taken up by rice plants but instead lost to the environment as ammonia, nitrate and nitrous oxide. The ‘reactive N’ also known as fixed N has a negative impact on human health as well as causes serious environmental problems. Surface runoff, denitrification, ammonium volatilization and leaching should all be managed in order to reduce the nitrogen loss from rice fields. Sustainable and environmentally friendly fertilizer management techniques raise the crop yields and enhance the sustainable soil fertility status. So it is necessary to implement management practices in order to reduce nitrogen losses and increase the nitrogen use efficiency (NUE) in rice production.

Abstract:

A field experiment was conducted during rabi seasons (December–March) of 2019–20 and 2020–21 to study the residual effect of nutrient management practices in lowland kharif rice varieties on succeeding black gram variety PU 31. The experiment was set in split plot design with four rice varieties in main plots (viz. CR 1009 sub-1, CR 1018, Pooja and Upahar) and six nutrient management practices in sub-plots [(viz. Control, 100% Recommended dose of fertilizers (RDF: 80-40-40 kg N, P2O5, K2O ha-1), 50% RDF+FYM (@ 8 t ha-1), 50% RDF+Sesbania green manuring (@ 1.5 t ha-1), Rice crop manager (115.5 -32.7-52.8- 25.0 kg N, P2O5, K2O, ZnSO4 ha-1+FYM @ 3 t ha-1) and Real time nitrogen management (RDF+customised leaf colour chart (CLCC)] and each treatment was replicated thrice. Among different nutrient management practices in rice, rice crop manager exhibited highest number of pods plant-1 (31.3), seeds pod-1 (7.8), 1000 seed weight (39.6 g), seed yield (877 kg ha-1), haulm yield (2512 kg ha-1), gross return (Rs. 51352 ha-1), net return (`Rs. 38947 ha-1) and return Rs.`-1 invested (`Rs. 4.14) and highest uptake of N (78.83 kg ha-1), P (7.60 kg ha-1) and K (53.09 kg ha-1) in residual black gram. This was at par with 50% RDF+FYM @ 8 t ha-1 and significantly higher than all other nutrient managements in preceding rice. So, nutrient management as per rice crop manger and 50% RDF+8 t FYM ha-1 to the preceding rice crop had significant residual influence in achieving highest yield and economic returns from succeeding black gram in rice-black gram cropping sequence.

Abstract:

It is sometimes argued that women play a more important role in seed and diversity management than men, and that women have greater abilities in managing crop diversity. In The Gambia, men and women also have the belief that women are better in managing and identifying varieties than men. This article focuses on the role of gender in farmer management of crop diversity in two crops, rice which is cultivated by women and pearl millet which is cultivated by men. First a historical overview is given of the role of gender in farming. The management of crop diversity in rice and millet and gendered knowledge in The Gambia is described in detail. Lastly, a grouping experiment with rice panicles and millet spikes is described. The article shows that clear differences exist between the farming practices of men and women, and these are based on a complex interplay of socio-economic and agro-ecological factors. But the differences in seed selection practices of men and women are small, and those differences that exist can best be explained by a complex of agroecological factors and rice and millet characteristics. The grouping experiment showed no significant differences in the way men and women grouped rice panicles and millet spikes. Together these findings suggest that the supposedly better skills of women in crop variety management are related to their gender identity rather than to any biological differences. Instead of taking the supposedly strong skills of women in seed and variety management as a starting point for agricultural development, it is better to understand the underlying mechanism that keep women in disadvantaged positions in rural societies and to try to change these mechanisms for their benefit.Key words: The Gambia, gender, agricultural labor, crop variety management

Abstract:

Rice striped stem borer damage the rice crops from the seedling to crop maturity and in sever infestation result in white ear head during the reproductive stage and dead heart during the tillering stage, which causes huge yield loss up to 60.0 %. The most crucial and essential component of the IPM strategy is pest monitoring, which is consistently evaluate the population and crop damage. Thus, the present research was performed to monitor and control the RSSB by using the different trapping devices in rice filed. Attraction in different trapping devices revealed that initially adult were caught during the first week of August and increased subsequently weeks in all trapping devices up to the October. Further data showed overall maximum seasonal adult population (195.30±19.25) was caught by pheromone traps followed by light traps (101.45±14.58), yellow color sticky traps (97.50±13.25) and yellow water pan trap (53.50±09.25), respectively. Furthermore, data exhibited the highest trapping efficiency (43.71%) was observed by the installation of pheromone traps followed by light traps (22.61%), yellow color sticky traps (21.70%) and water pan trap (11.97%), respectively. In addition, impact of the treatments was observed by calculate the crop damage symptoms and minimum crop damages i.e white ears and dead hearts (09.94±1.25%) and (09.39±1.10%) were recorded pheromone traps followed by light traps (12.59±1.25%) and (11.88±1.62%), yellow color sticky trap (YCST) (17.89±1.89%) and (17.48±2.10%), and yellow water pan trap (YWPT) (25.64±2.46) and (22.81±3.23), control (42.68±7.23) and (39.03±07.12) were recorded, respectively. Furthermore, results showed the highest average yield (4865.00 kg/haˉ1) was obtained in the plots where pheromone traps were installed, followed by light traps (4608.00 kg/haˉ1), YCST (4230.50 kg/haˉ1), YWPT (4205.0 kg/haˉ1) and in control (4037.60 kg/ haˉ1), respectively. Based on the present findings, highest adult attraction, lowest crop damage and significant high yield, thus, pheromone and light traps are the convenient tools to control adults of rice striped stem borer in rice.

Abstract:

Proper application of nitrogen (N) fertilizer is vital to improve the growth and grain yield of rice crop. As there prevails more aerobic period in direct seeded rice, nitrogen loss is generally more in such environment. Therefore, nitrogen recommendation for direct seeded rice is slightly higher (22.5-30 Kg ha-1) than that under the transplanted rice. Insufficient and/or inappropriate nitrogen fertilizer application is highly critical to the crops. Optimal nitrogen management strategies aim at matching the nitrogen fertilizer supply to the actual crop demand. Leaf color is generally used as a visual and subjective indicator of the rice crop need for nitrogen fertilizer. The Leaf Color Chart is a simple and inexpensive tool for real time nitrogen management in rice. It helps farmers to improve their decision-making process in nitrogen management. It provides the idea of when and how much nitrogen fertilizer to apply based on relative greenness of the rice leaf. In overall, LCC based nitrogen management improves productivity and profitability of the rice crop by nitrogen saving and ensuring its higher use efficiency.Int. J. Appl. Sci. Biotechnol.

Abstract:

Rice (Oryza sativa L.) is the second most important staple food crop of world and prime staple food crop of India. Rice (Oryza sativa L.) and rice-based cropping systems are integral part of agriculture whose spread and extent is predominant across the countries. The productivity and sustainability of rice-based systems are threatened by the inefficient use of inputs (fertilizer), increasing scarcity of especially water, climate variability and availability of labour. Method of establishment and N management practices influences the performance of rice through its effect on growth and development. A field experiment was conducted during kharif 2021-22 and 2022-23 at ICAR-Indian Institute of Rice Research, Rajendranagar, Hyderabad to study the “Effect of site specific N management and different crop establishment methods on tillering ability and dry matter accumulation in rice”.The experiment was laid out in split plot design with three crop establishment methods [Manual transplanting (M1) mechanical transplanting (M2) and wet direct seeded rice (M3)] in main plots and five nitrogen management practices [S1- Recommended nitrogen dose (RND), S2-Leafcolorchart (LCC), S3-Nutrient Expert (NE), S4-Greenseeker (GS), S5-Soil test crop Response STCR] in sub-plots with three replications. The results revealed that under crop establishment methods, mechanical transplanting recorded higher tiller bearing capacity per m-2 (384,446 and 415 m-2) as well dry matter production (kg ha-1) (13927, 14395 and 14161) while in nitrogen management practices soil test crop response STCR recorded higher tiller production ability per m-2 (414,468 and441m-2) and drymatterproductio (kg ha-1) (13949, 14772 and 14360 kg ha-1). The results suggest that timely transplanting of younger seedlings, appropriate N management practice based on STCR achieved better crop stand with higher tillering ability and dry matter production efficiency.
