Abstract:
Engineering technological especially on automation and mechanization in agricultural and plantation industry is still new and still under research and development. The application of computer, mechatronics and machines for agricultural production has been one of the outstanding developments in Malaysian agriculture. This paper describes on the recent research at Malaysian public university on the uses of computer and electronics towards machines for the agricultural operations. It has been generally agreed that industrial robotics do not provide sufficient information related to the bioproduction field, although some fundamental theories and technologies were applicable to the bioproduction machine. Agricultural products are diversified and complicated, the environment around the objects changes from time to time, and the machine mechanism should adapt to physical properties and cultivation methods of the biological objects. These are some of the considerations that agricultural mechanization needs to address. Current trend in agriculture is integration with biotechnology application, the demand of which may increase in conjunction with the land capabilities by variety humanity activities. Although adoption of one agriculture activity per house area is a viable strategy in the framework of food security, as in a general, an agricultural production is labour intensive. The agricultural landscape has seen an increase in adoption of modern technologies, be it in small scales, including those in the agro-based manufacturing sector. This, to some extent, has increased the productivity and at the same time decreased the labour dependency. In conclusion, studies on electronic and computer-assisted devices leading to automation for application in agriculture had to be perpetually carried out.

Abstract:
Most research about genetic engineering and organic agriculture has concentrated on the views of consumers and farmers. Given the important role that scientists, extension officers and academics play in creating innovations, influencing farmer adoption and informing the public, a telephone survey targeting these individuals (n = 185) was conducted in mid 2004. The purpose of this survey was to identify the beliefs of agricultural professionals employed in the Australian public sector towards organic agriculture and genetic engineering. The beliefs of agricultural professionals about the benefits and costs of organic agriculture and genetic engineering are compared and contrasted, providing an important benchmark on their views towards these innovations. More professionals believe in the positive net benefits of genetic engineering than those who believe in the positive net benefits of organic agriculture. They believe that genetic engineering will play a vital role in influencing the sustainability of Australian agriculture in the future, namely by increasing production and improving pest and disease management. However, many professionals voiced concerns about the potential costs of genetic engineering, with many citing risk and uncertainty issues and the lack of long-term testing. At the same time, beliefs towards organic agriculture in Australia by agricultural professionals seem to be changing, with nearly two-fifths of those surveyed saying that their beliefs had become more positive towards organic agriculture in the past 5 years. The main benefit of organic agriculture is seen to be a reduction in chemicals. The main limitations are seen to be economic and production difficulties.

Abstract:
Purpose – The purpose of this paper is to introduce a continuous time version of the speculative storage model of Deaton and Laroque (1992) and to use for pricing derivatives, in particular insurances on agricultural prices. Design/methodology/approach – The methodology of financial engineering is used in order to find the partial differential equations that the dynamics of derivative prices have to satisfy. Furthermore, by using the Monte-Carlo method (and Feynman-Kac theorem) the insurance prices is computed. Findings – Results of this paper show that insurance prices (and derivative prices in general) are heavily influenced by market structure, in particular, the demand function specifications. Furthermore, through an empirical analysis, the performance of the continuous time speculative storage model is compared with the geometric Brownian motion model. It is shown that the speculative storage model outperforms the actual data. Practical implications – Since the agricultural insurances in many countries are subsidised by government, the results of this paper can be used by policy makers to measure changes in agricultural insurance premiums in scenarios that market experiences changes in demand. In the same manner, insurance companies and investors can use the results of this paper to better price agricultural derivatives. Originality/value – The issue of agricultural insurance pricing (in general derivative pricing) is of great concern to policy makers, investors and insurance companies. To the author’s knowledge, an approach which uses the methodology of financial engineering to compute the insurance prices (in general derivatives) is new within the literature.

Abstract:
Petroleum agriculture, characterized by mechanization and chemistry, is developing rapidly in China. However, petroleum agriculture has not only brought food safety problems, but also caused great obstacles to the sustainable development of society. In view of the disadvantages of oil agriculture, we provide an upgrading plan for energy systems in agriculture. This work can help reduce carbon emissions and improve food security. We introduce the most advanced technologies in Chinese agricultural development and the technical scope includes new agricultural energy power generation, agricultural energy use and the safe operation of agricultural energy systems. We describe the detailed data of agricultural bioenvironmental and energy engineering to clarify the level of agricultural energy efficiency in China. The overall conclusion of this paper is that the deep integration of agriculture and energy internet has become the development trend of agricultural energy systems.

Abstract:
The agricultural mechanization development can promote the high-quality development of agriculture, but the agriculture which faces the huge environmental pressure also needs to transform to the green sustainable development. Based on agricultural panel data of 30 provinces in China from the year 2008 to 2017, this paper measures the level of agricultural green transformation using the Malmquist–Luenberger (ML) index. Furthermore, the spatial panel econometric model is used to empirically investigate the impact of agricultural mechanization development on this green transformation. It concludes that the agricultural green transformation in western China shows an upward trend in fluctuations, with its overall transformation level still lower than the national average level. Besides, the agricultural mechanization operation level in the western region has a positive role in promoting the green transformation of agriculture, while the agricultural mechanization equipment level shows the opposite force. Compared with southwest China, the agricultural mechanization operation level in northwest China has a more positive impact. The improvement of farmers’ income and agricultural technology has positive impacts on agriculture green transformation in the whole western region, while agricultural human capital shows an opposite impact on the northwest and southwest.

Abstract:
The Alto Rio Lerma Irrigation District (ARLID), located in the state of Guanajuato in Mexico, is an agricultural area whose sustainability depends partially upon groundwater withdrawal for crop irrigation. Because of high pumping demands and current land-management practices, water levels in the regional groundwater aquifers have declined severely, resulting in aquifer overdraft. The potential adverse consequences of this overdraft cannot be overstated, as the long-term economic viability and environmental integrity of the region is threatened. In order to analyze this economic, environmental, and water use problems in this region, simulation of the agricultural system was performed and associated water use impacts quantified under different management scenarios. Linear programming identified the 12 optimal cropping patterns, and then multi-criteria decision-making methodologies were applied to rank and identify the best cropping pattern (satisficing solution). The GLEAMS model was used to simulate the amounts of water, nitrate, and pesticides in both runoff and percolation for each cropping pattern. In order to quantify the economic and environmental impacts of aquifer overdraft, two attributes were used; pumping costs and an aquifer exploitation coefficient. Three multiple criteria methods: Q-analysis, ELECTRE II, and the Range of Value Method, were evaluated and the latter method was selected to analyze the payoff matrix for the ARLID, where 12 alternatives, each with 13 attributes, were considered. The results show the best alternative for effectively balancing environmental with economic considerations was the farming practice, consisting of land leveling, growing vegetables such as red tomato, and controlled groundwater withdrawals to preserve aquifer sustainability. Low water availability does not necessarily reduce farmer's profits, if new water saving alternatives are applied, combined with more profitable crops. Given that ROV method only considers full compensation between objectives, this research contemplate an extension for the nonlinear case in order to assess the whole range of values of the objective function. The final findings suggest that the best methodology was to apply L1 in the lower levels and then L2 for the highest level in the hierarchy. In this manner, the partial compensation between objectives is considered and also the decrease in the uncertainty of alternatives selection.

Full text
Abstract:
Ammonia is the most prevalent alkaline gas in the atmosphere and plays an important role in environmental pollution through acidification and eutrophication. Livestock are the largest source of ammonia in the UK, mainly originating during storage and spreading of animal manure. The aim of this study was to validate the collection efficiency of recurved passive ammonia flux (PAF) samplers and the flux frame method to provide a robust methodology for measurement of distributed agricultural sources of ammonia outdoors. The collection efficiency of recurved PAF samplers was determined in a wind tunnel under controlled conditions of ammonia flux (0.771 - 13.49 mg NH3 m-2 s-1), and at angles of orientation to the flow direction (0, 30, 60, 70, 80, 90°). The samplers were effective up to a wind speed of 7 m s-1 and an angle of 80°, with a mean collection efficiency of 71%. The flux frame method had a mean collection efficiency of 87.4% when used with ground level point sources under controlled conditions in the Atmospheric Flow Laboratory. However, in controlled field releases, the efficiency fell to 56.4%. The flux frame method was also suitable for line sources, although assumptions must be made about the source homogeneity and plume dispersion. ADMS modelling was used to predict the collection efficiencies for the flux frame method and these agreed with measured collection efficiencies to within 37.3%. A comparison of source strengths determined using a full size flux frame and portions of the flux frame showed that a full size flux frame was unnecessary as one column of samplers produced a very similar estimate to that of the whole frame. The validated method was then used to measure ammonia emissions from free-range pigs. The amount of ammonia emitted from this source was very low and less than 0.16 g (kg of sow)-1 day-1.

Abstract:
Anaerobic digestion technology has not gained widespread acceptance on UK farms due mainly to the long return on investment periods involved. It has been suggested that co-digestion of agricultural and industrial wastes may enhance the economic viability of such installations. Batch and continuous digestion of cattle slurry and organic industrial wastes was carried out in specially constructed pilot plant digesters, to determine optimum mixtures of waste and digester loading rates. A total of 10 different wastes were tested, on a batch digestion basis, for their potential to co-digest with cattle slurry. Of these, 3 were chosen for continuous pilot plant trials, due to either a need to provide a disposal route for the waste, or positive effects of the waste on methane productivity. Chicken manure was found to slightly enhance methane productivity, but ammonia inhibition of methanogenic bacteria was noted over time. The organic fraction of municipal household waste (OFMSW) significantly enhanced digester methane productivity, while fish offal (FO) slightly enhanced methane productivity when added to the digester in small quantities, but quickly caused digester failure when added in larger amounts. An economic model of a digestion facility was developed and used to show the financial benefits of co-digestion.

Soil erosion is one of the most important of today’s global environmental problems. Over the past few decades, soil conservation practices were implemented to reduce soil erosion in the United States. However, excessive sediment still remains among the most prevalent water quality problems. Agricultural fields and in particular ephemeral gullies (EGs) are considered to be a major contributor of sediment. The overall goal of this study was to improve modeling utility to identify and quantify sources of sediment. Specific objectives were: (1) to develop and demonstrate a method of field-scale targeting using Soil and Water Assessment Tool (SWAT) and to use this method as a targeted, flexible approach to pay explicitly for sediment-yield reductions; (2) to evaluate topographic index models (Slope Area [SA], Compound Topographic Index [CTI], Slope Area Power [SAP] and Wetness Topographic Index [WTI]) and a physical-based model (Overland Flow Turbulent [OFT]) in predicting spatial EG location and lengths. Black Kettle Creek watershed was the focus of an innovative project to pay for modeled field sediment reductions. An Arc-Geographical Information System (GIS) tool bar was developed that post processed SWAT hydrologic response unit output to field boundaries and prepared maps of high-priority fields by sediment, total nitrogen, and total phosphorus and was demonstrated to be useful for field-scale targeting. Calibrated SWAT model was used to establish baseline sediment yields. Various Best Management Practices (BMPs) were simulated and payments to implement each BMP for a given field were calculated. This study helped to guide determination of appropriate farmer support payments and quantified the important influence of BMP type and site-specific conditions for use in targeting conservation practice funding to achieve maximum soil-loss reductions per dollar spent. Extreme care should be used in selecting the source of spatial model input data when using SWAT for field-level targeting. Automated geospatial models were developed in a GIS environment to spatially locate and derive length of EGs using topographic index and physical based models. EG predictions were better for the SA model among the four topographic index models tested. Individual calibration of topographic index model threshold for each application site was needed. An OFT model (physical based model), which utilized topography, precipitation, soil, landuse/landcover and SWAT-based runoff estimates, did not need individual site calibration, and may have broader applicability than empirical based models.

Abstract:
The well-known and widely accepted Penman combination equation was applied to climatic data collected in a desert environment to predict actual evapotranspiration if the desert region were developed into irrigated agriculture. The Penman evaporation estimates from desert climate data were compared to Bowen ratio ET measurements collected on irrigated alfalfa fields in the general vicinity. Six variations of the wind function in Penman's equation were tested. From these six the best fit-model was determined. surprisingly, Penman's original equation provided the best fit (in mean hourly units W m⁻²) as PLE₁ = 0.953LE + 43. The s.e. was 51 W⁻², r² = 0.953, and n = 298 hourly points. A calibrated wind function was developed and named 'Sonoran'. The Sonoran wind function PLE₆ = 0.954LE + 24, s.e. = 48.8 r² = 0.956 provided virtually imperceptible improvements over Penman's original wind function.

A series of experiments was conducted to compare methods used to evaluate the durability of animal feed pellets, as well as to investigate the potential for modeling the effects of formulation and processing factors on both pellet durability index (PDI) and pelleting energy consumption, measured in kilowatt hours per ton (kWh/ton). Seven different factors, including ground corn particle size, added fat level, inclusion of distillers dried grains with solubles (DDGS), feed rate, steam conditioning temperature, conditioner retention time, and pellet die thickness (L:D ratio) were examined. Each factor was evaluated at two levels, and treatments were developed in order that all factor to factor comparisons could be made. Pellet samples were analyzed according to the standard method as described in ASAE S269.4, a modification of this method, and by using the NHP100 pellet tester set to each of its four testing intervals (30, 60, 90, and 120 seconds). The standard method was found to provide the most consistent and repeatable determinations of pellet durability, and was found to correlate well with the modified method, as well as with the NHP100 results at 30 and 60 seconds. Physical attributes of feed pellets, such as pellet hardness, bulk density, and moisture content were found to have significant, but weak correlations with pellet quality. Pellet quality was found to be significantly influenced by all factors other than ground corn particle size and feed rate. Higher fat level, lower conditioning temperature, and the thinner pellet die most significantly lowered pellet quality, with increasing effect respectively. A regression model was developed that was able to predict pellet durability within an average of 1.1 PDI. Pelleting energy consumption was found to be significantly influenced by all seven factors, with the higher fat level, thinner pellet die, and higher conditioning temperature most improving efficiency, with increasing effect respectively. A regression model was developed that was able to predict energy consumption within an average of 0.3 kWh/ton. The successful creation of regression equations demonstrates that there is potential for modeling and optimizing pellet quality and energy consumption within a pelleting operation.

Abstract:

The original ARID (Algae Raceway Integrated Design) raceway was an effective method to increase temperature toward the optimal growth range. However, the energy input was high and flow mixing was poor. Thus, the ARID-HV (High Velocity Algae Raceway Integrated Design) raceway was developed to reduce energy input requirements and improve flow mixing. This was accomplished by improving pumping efficiency and using a serpentine flow pattern in which the water flows through channels instead of over barriers. A prototype ARID-HV system was installed in Tucson, Arizona, and the constructability, reliability of components, drainage of channels, and flow and energy requirements of the ARID-HV raceway were evaluated. Each of the electrical energy inputs to the raceway (air sparger, air tube blower, canal lift pump, and channel recirculation pump) was quantified, some by direct measurement and others by simulation. An algae growth model was used to determine the algae production rate vs. flow depth and time of year. Then the electrical energy requirement of the most effective flow depth was calculated. Channel hydraulics was evaluated with Manning's equation and the corner head loss equation. In this way, the maximum length of channels for several raceway slopes and mixing velocities were determined. Algae production in the ARID-HV raceway was simulated with a temperature and light growth model. An energy efficient design for the ARID-HV raceway was developed.

Texturized vegetable protein (TVP) based foods offer several advantages compared to animal protein, including lower costs and improved health benefits. Wheat gluten is often processed using extrusion to produce TVP. Processing aids, such as reducing agents (example, cysteine and sodium metabisulfite) and pH modifiers (example, tetra potassium phosphate) aid in texturization. Reduction of sulfhydryl groups, cleavage of disulfide bonds, and reformation of bonds between elongated protein molecules results in protein aggregation and texturization. This study focused on development of a fundamental understanding of these mechanisms for texturization using analytical tools such as the phase transition analyzer (PTA), in combination with lab- and pilot-scale extrusion. The abovementioned three chemicals were added to four varieties of gluten. The control treatment had no additives. PTA was used to understand the operative flow properties of gluten in an environment similar to an extrusion system. Addition of sulfite (0.18%) and cysteine (0.18%) lowered the thermal softening (Ts:36.6-44.1 °C) and thermal flow (Tf:79.6-105.6 °C) temperatures of all varieties of gluten as compared to the controls (Ts:38.8-48.2 °C; Tf:91.7-112.2 °C). Phosphate (3%) did not have the same lowering effect on Ts (40.2-47.0 °C) and Tf (96.2-108.2 °C), indicating a different mechanism. Extrusion studies were conducted to gain an understanding of the reformation of disulfide bonds and texturization. Two of the varieties of gluten, a “superior” one that texturizes well and an “inferior” gluten requiring texturizing aids, were processed on a lab-scale extruder. Pilot scale extrusion was used to process the other two glutens (“superior” varieties) to obtain commercial quality products, which were evaluated for degree of texturization (hydration rate, absorption index and integrity). During lab-scale extrusion, texturization was observed only in the case of phosphate and corresponded with an increase in specific mechanical energy (SME) as compared to the control, indicating disulfide bond reformation. Phosphate also led to significantly (p<0.05) better texturization during pilot-scale extrusion, although SME trends were different due to higher in-barrel moisture and a more ideal extrusion system. Fourier Transform Infrared Spectroscopy was used to examine protein structural changes and indicated a loss of α-helix structure in TVP with an increase in β-sheet formation.

Mobile apps are useful tools for many different purposes. In agriculture, apps can be used to check the weather and markets, control irrigation, and monitor machine activity among other uses. This research project is a collaboration between Kansas State University and AGCO and includes the development of two apps, using MIT Application Inventor and Google App Engine. Kansas State University was responsible for developing the apps user interface and functionality while AGCO provide the data needs for the apps through Google App Engine. The first app is called Crop Maturity App and measures Growing Degree Days from a crops planting date. The second app is called Combine Efficiency App and determines the performance of a combine harvesting based on its speed. AGCO provided the server support for these apps from a weather service and their own combines that are connected. This project demonstrates the possibility of an open-source development environment with AGCO machine data.

Abstract:
In general the agricultural policy South East European countries are characterized by high volatility, which is expressed in terms of applied instruments and measures as well as in regard to the products to which it relates. In the first phase of price and trade liberalization, most countries have abolished or significantly reduced non-tariff barriers to the import and export of a wide range of products. Also, most countries have reduced or abolished production subsidies and left import tariffs as the main instrument to protect producers. This chapter emphasizes that the further development of CAP in many ways depended on negotiations with the countries of Southeast Europe. Some of these countries are already in the EU and some candidate countries which are at different levels of negotiation with the EU. Southeast European countries are basically agricultural country with low productivity and low prices of agricultural products to be completely restructured. These countries can be reintegrated into CAP only respect the rules and with the help of EU member states.

Abstract:
Aquatic ecosystems do not contain more than a fragment of the global water resources, but they are exclusive and complex habitats due to the extremely close association between terrestrial and aquatic habitats. The important fish stocks and a unique set of organisms that provides priceless consumer services, such as chemical water purification and organic matter processing, are affected. The pollution of aquatic ecosystems with pesticides applied in agricultural production is widely acknowledged as one of the greatest anthropogenic stressors to stream ecosystems, and agricultural pesticides are known to cause a threat to all living organisms in stream ecosystems. The general objective of this chapter is to study the effects of agricultural pesticides on invertebrates. There are only a few evaluating effects of pesticide contamination resulting from normal agricultural practice on invertebrates, and there is a lack of studies focusing on the indirect effects of pesticides. The importance of physical habitat degradation in the assessment and mitigation of pesticide risk in agricultural streams will be discussed.

Abstract:
Nanotechnology can contribute to food security in supply chains of agri production-consumption systems. The unique properties of nanoparticles have stimulated the increasing interest in their application as biosensing. Biosensing devices are designed for the biological recognition of events and signal transduction. Many types of nanoparticles can be used as biosensors, but gold nanoparticles have sparked most interest. In the work presented here, we will address the problem of fruit and vegetable decay and rotting during transportation and storage, which could be easily generalized also onto post-harvest loss prevention in general. During the process of rotting, different compounds, including different gasses, are released into the environment. The application of sensitive bionanosensors in the storage/transport containers can detect any changes due to fruit and vegetable decay and transduce the signal. The goal of this is to reduce the logistics cost for this items. Therefore, our approach requires a multidisciplinary and an interdisciplinary approach in science and technology. The cold supply chain is namely a science, a technology and a process which combines applied bio-nanotechnology, innovations in the industrial engineering of cooling processes including sensors for temperature and humidity measurements, transportation, and applied mathematics. It is a science, since it requires the understanding of chemical and biological processes linked to perishability and the systems theory which enables the developing of a theoretical framework for the control of systems with perturbed time-lags. Secondly, it is a technology developed in engineering which relies on the physical means to assure appropriate temperature conditions along the CSC and, thirdly, it is also a process, since a series of tasks must be performed to prepare, store, and transport the cargo as well as monitor the temperature and humidity of sensitive cargo and give proper feedback control, as it will be outlined in this chapter. Therefore, we shall discuss how to break the silos of separated knowledge to build an interdisciplinary and multidisciplinary science of post-harvest loss prevention. Considering the sensors as floating activity cells, modelled as floating nodes, in a graph of such a system, an extended Material Requirement Planning (MRP) theory will be described which will make it possible to determine the optimal feedback control in post-harvest loss prevention, based on bionanosensors. Therefore, we present also a model how to use nanotechnology from the packaging facility to the final retail. Any changes in time, distance, humidity or temperature in the chain could cause the Net Present Value (NPV) of the activities and their added value in the supply chain to be perturbed, as presented in the subchapter. In this chapter we give the answers to the questions, how to measure the effects of some perturbations in a supply chain on the stability of perishable agricultural goods in such systems and how nanotechnology can contribute with the appropriate packaging and control which preserves the required level of quality and quantity of the product at the final delivery. The presented model will not include multicriteria optimization but will stay at the NPV approach. But the annuity stream achieved by improved sensing and feedback control could be easily combined with environmental and medical/health criteria. An interdisciplinary perspective of industrial engineering and management demonstrates how the development of creative ideas born in separate research fields can be liaised into an innovative design of smart control devices and their installation in trucks and warehouses. These innovative technologies could contribute to an increase in the NPV of activities in the supply chains of perishable goods in general.

Abstract:
The development of the biofuel industry and the production of bioethanol and using it as a fuel in the world in general and in Ukraine in particular are analyzed in the paper. Bioethanol is mostly produced from sugar- and starch-containing raw materials. It is noted that bioethanol is obtained mainly from molasses in Ukraine. Molasses is a by-product of sugar beet production. The prospects of second-generation bioethanol production made from unfit for human consumption lignocellulosic biomass such as agricultural by-products, forestry residues, municipal waste are considered. Pretreatment of lignocellulosic biomass is the main task in bioethanol production from such raw materials. Partial or complete hydrolysis of hemicellulose and the conversion of crystalline cellulose into an amorphous state are required to destroy the strong structure of the lignocellulosic complex and remove lignin for further processing. The method of Discrete-Pulse Energy Input was used to intensify the production of bioethanol from lignocellulosic biomass. The method allows shortening the duration of pretreatment, hydrolysis and fermentation, increasing the amount of reducing substances in the wort, reducing energy consumption and generally making this technology more economically attractive. The universal heat and mass exchange installation in order to reduce energy and resource consumption in bioethanol production from lignocellulosic biomass is developed at the Institute of Engineering Thermophysics of the NAS of Ukraine. The Installation allows carrying out the processes of dispersion, dissolution, heating, hydrolysis at the same time in one apparatus.

Abstract:
It is generally believed that free trade plays a vital role in stabilizing food supplies and food prices since abundant foods stocks in some countries coexist with shortages in some others. Contemporary global trade system, however, is becoming increasingly distorted by unfair and inefficient policies in many countries, creating both winners and losers among not only small developing economies, but also largest producers of food and agricultural products. One of the recent examples of such distortion is US-China trade tensions and potential tariff escalations where the agricultural sector is the most vulnerable. By raising import tariffs on food and agricultural products in response to protectionist policies, the countries may face a situation of rising prices for consumers, limited market access for producers, and increasing pressures on food security. In this chapter, the author develops the theme of the effects of globalized agricultural trade on food security with a critical focus on the importance of balancing trade liberalization and protectionism.

Abstract:
American power at the end of World War II was paramount. The usual image of this might, however, is formed more by the array of military and industrial components of American culture than by something as seemingly mundane as wheat breeding. Nuclear-tipped missiles, airplane and tank factories, engineering prowess, and motivated soldiers are more generally assumed to be the components of military strength, not scientists patiently crossing one strain of wheat with another and searching through the progeny for a better variety. In the direct exercise of military power, of course, the weapon systems and soldiers are the most important elements of power. Armies, however, exist only on the foundation of food supplies that are adequate for both the military personnel and their civilian support force. American strategists in both world wars were acutely aware of the role of agriculture in the projection of military might, and they considerably amplified agriculture’s importance in the aftermath of World War II. Specifically, through a variety of public and private initiatives, wheat breeding and other lines of agricultural science became an integral part of postwar American strategic planning. Put somewhat differently, after 1945, wheat breeding by American scientists became more than just an exercise in the modernization of agriculture. Old motivations for seeking new varieties did not disappear, but new motivations arose to justify expenditures. In addition, American scientists came to do their work not only in the United States for American farmers but overseas for foreign governments. Wheat breeding acquired ideological dimensions more elaborate than simply “the promo tion of progress.” Instead, wheat breeding and other agricultural science became part of the “battle for freedom.” In the process, many countries moved to new relationships with each other and with their own natural resource base. How did wheat breeding get caught up with strategic and national security considerations? It is necessary to follow a somewhat convoluted trail to answer this question, and the story can begin with the status of the United States after the collapse of Germany and Japan in 1945.

Abstract:
Agricultural technology transfer to people in the developing world is a potentially powerful tool to raise productivity and improve livelihoods. Despite this, many technologies are not adopted by their intended beneficiaries. Qualitative studies have identified guidelines to follow in the design and dissemination of agricultural technology, but there has been comparatively little synthesis of quantitative studies of adoption. This study presents a meta-analysis of adoption studies of agricultural technologies in the developing world. The results confirm most earlier findings, but cast doubt on the importance of some classic predictors of adoption, such as education and landholding size. Contact with extension services and membership in farming associations are found to be the most important variables in predicting adoption. Attributes of the technologies are found to modify the relationships of predictor variables to adoption. Membership in farming associations and farmer experience are found to be positively linked to adoption in general, but for technologies that reduce labour the effect is amplified. The findings have potential implications for researchers, extension workers, and policy makers.

Abstract:
Agricultural production is one of the main sources of nitrogen and phosphorous inputs to the water bodies. Quantifying nutrient input from agriculture is needed both to develop effective environmental measures and to justify the technologies to be applied with due account for local natural and climatic conditions. Several related national studies have been conducted since 2015. Institute for Engineering and Environmental Problems in Agricultural Production (IEEP) methodology was used for this purpose. It determines the nitrogen and phosphorus content in the arable layer, including N and P amounts applied with mineral and organic fertilisers. Such factors as soil type and texture, the distance to the water bodies and the land use structure are used to estimate the nutrient input to the water bodies. In addition, the consistency of manure handling technologies with Best Available Techniques (BAT) principles is taken into account through introduction of relevant coefficients. Calculation results according to IEEP methodology were used in the follow-up general assessment of the nutrient load on the water bodies from different sources with the use of Institute of Limnology Load Model. Satisfactory correspondence between the assessment results and the values calculated using the monitoring data confirmed the adequacy of the above assessment procedure. Following its outcomes, the nutrient reduction potential of agricultural sources is approximately 10–20 %.

Groundwater, which is a strategic resource in Turkey, is used for drinking-use, agricultural irrigation and industrial purposes. Population increase and total water consumption are constantly increasing. In order to meet the need for water, over-shoots from underground water have caused significant falls in groundwater level. Estimation of water level is important for planning an efficient and sustainable groundwater management. In this study, groundwater level, monthly mean precipitation and temperature observations of Turkish General Directorate of State Hydraulic Works (DSI) in Hatay, Amik Plain, Kumlu district were used between 2000 and 2015 years. The performance evaluation was done by creating Multi Linear Regression (MLR) and Artificial Neural Networks (ANN) models. The ANN model gave better results than the MLR model.

This article offers a universal methodology for the design, creation and operation of complex electrotechnological systems. This methodology is based on a system-process approach to business modeling. The article provides a detailed description of all private business processes that provide a full cycle of business engineering, and offers a General mathematical expression for a comprehensive assessment of the effectiveness of the business engineering process. The proposed methodology has been tested on the example of designing, creating and operating vegetation climate systems (VCS). This example shows that it is possible to conduct quite serious scientific research at the intersection of plant physiology and electric power engineering, which allows us to create modern self-adjusting systems for automatic microclimate control when growing plants. Application of engineering methods allows to increase the efficiency of development of information systems for automatic control of parameters of the most important physiological processes (photosynthesis, transpiration, etc.) in plants under the influence of environmental factors. The article outlines the prospects for the development of the subject area of engineering in the direction of solving specific problems to integrated energy engineering, and the energy business - from trading individual services to trading models and technologies.

Abstract:
In this study, a numerical representative volume element (RVE) model was used to predict the mechanical properties of a Rice Husk Particulate (RHP)-Epoxy composite for use as an alternative material in non-critical applications. Seven different analytical models Counto, Ishai-Cohen, Halpin-Tsai, Nielsen, Nicolais, Modified Nicolais and Pukanszky were used as comparison tools for the numerical model. The mechanical properties estimated for 0%, 10% and 30% RHP-Epoxy composites using the numerical and analytical models are in general agreement with each other. Using the analytical models, it was calculated that an increase in volume percentage of RHP to 30% led to continual reduction in elastic Young’s modulus and ultimate tensile strength of the composite. The numerical RVE models also predicted a similar trend between filler volume percentage and material properties. Overall, the results of this study suggest that RHP can be used to reduce the composite raw material costs by replacing the more expensive polymer content with agricultural waste products with limited compromise to the composite’s mechanical properties.

Abstract:
Abstract This paper describes the motivation and development of a human-powered roll stabilization attachment for utilitarian two-wheeled vehicles. The proposed design has been built and tested by the authors in both on- and off-road conditions. It provides balance by providing a rolling platform underneath the two-wheeled vehicle (motorcycle) for the user to push against with their feet. This platform is placed under the driver’s sitting position and is towed from a three degree-of-freedom joint behind the front axle (i.e. one of the implementations uses a ball hitch joint). Fifty eight percent of the world’s motorcycles are in Asia Pacific, and Southern and Eastern Asia. In most of those countries, motorcycles greatly outnumber cars and many of these motorcycles function as utility vehicles. The uses of motorcycles include transportation of goods on the bike frame, transportation of goods on a trailer, and even pulling agricultural implements in farms. If no modifications are made to the motorcycle, at slow speeds operators of motorcycles must drag their feet on the ground and lightly push upwards as needed to retain balance. Attaching conventional outrigger wheels, similar to a motorcycle side-car, can negate some of the advantages of motorcycles that users value by: (A) preventing leaning into turns when rigid outriggers arms are used, (B) significantly increasing complexity and mass when outrigger arms mounted on suspension systems are used, and (C) increasing the vehicle’s width such that it can no longer travel between car lanes or between rows of growing crop. An additional design consideration for balancing motorcycles is the user’s need for quick conversion between a statically balanced vehicle and a vehicle can lean dynamically in turns, for example for someone who wishes to operate a motorcycle on farms but also travel quickly between agricultural fields. This conversion convenience is affected not only by the ease of attaching and detaching the balancing system but also by the ability to comfortably carry on the balancing system on the motorcycle even when it is not being used, such that it can be deployed when it is needed. This paper describes a design for a human-powered roll stabilization attachment that address these concerns and other identified user needs. It also provides with general equations to design similar human-powered roll stabilization systems for motorcycles.

Abstract:
The general problem of an appropriate erosion modelling can be seen in a lack of available data and in the validation and verification of the methodologies applied. The article includes two significant and challenging topics, i.e. the evaluation of the sediment amounts in a catchment and the validation of the methodologies used. The importance of the sediment estimation can be found not only in the modelling and prediction fields but also in the terms of engineering practice. The significance of erosion model validation lies in the confidence in the model itself and in the detection of its applicability and relevance. In this study, results obtained from the physically-based EROSION-3D model was compared with the sediment yield of a small agricultural catchment in central Poland. The estimation of sediment yield from the agricultural catchment has been conducted using the empirical method (USLE) coupled with a sediment delivery ratio (USLE-SDR) and verified by reservoir measurement. Firstly, the application of a physically-based EROSION-3D model has been done based on a continuous rainfall series for the selected period and afterwards the results have been compared with the sediment yield obtained by the empirical methods in order to test a model´s performance. The results of the paper point to the comparison of the results obtained by two different approaches, i.e. the physically-based and empirical methods together with the validation of the methods through the acoustic depth measurements.

Abstract:
This study presents the experimental combustion characteristics of biomass briquettes made from agricultural wastes (coconut fiber and corn cob) of Córdoba-Colombia. For this thermochemical conversion, the actual heat transfer during the process and the main combustion characteristics are also studied. Initially, several corncob and coconut fibers briquettes were produced and burned. The non-adiabatic flame temperatures and the air velocity were measured. To study the combustion process dynamics, a process simulation was performed in EES Software© using the typical mass balances of a combustion process, and taking into account the possible stoichiometric equation, using as input the elemental analyzes of each biomass and the excess air that was determined experimentally. The exhaust gases and completeness combustion with moist air were evaluated and usual combustion parameters and correlations like energy balance, enthalpy of formation of the exhaust gases and process exergy were calculated. Likewise, the heat transfer by convection, radiation and heat flow at the gas outlet was evaluated, referenced to the process temperatures. It was found that values of non-adiabatic flame temperature were around 500 ° C, while surface and gases temperatures were between 60–81 ° C and 60 ° C respectively. In general, low emissions of harmful gases to the atmosphere were generated during the combustion of these briquettes. As well, the energy availability at the outlet can be used for moderate heating processes. These findings make these types of biomass a viable alternative to be utilized as renewable energy source.
