A Worldwide Comparison of Water Use Efficiency of Crop Production
Worldwide food security and water safety issues necessitate countries with low water use efficiency of crop production (CWUE) to increase it and reduce regional CWUE variations. CWUE function was estimated with stochastic frontier analysis, and CWUE variation was decomposed on inter-continental, intra-continental and international level with variance decomposition method. It is proposed that in...
متن کاملMaize productivity and nutrient use efficiency in Western Kenya as affected by soil type and crop management
Low soil fertility and high weed infestation are the main culprits for the declining maize production inWestern Kenya. Technology packages to address these constraints exist, but their effectiveness is likely to be influenced by variability in soil types and farm management practices in the region. Trials were conducted during the 2008/2009 cropping seasons to investigate the nutrient use e...
متن کاملNon-Parametric Energy Use Efficiency, Energy Ratio and Specific Energy for Irrigated Wheat Crop Production
In this paper, non parametric Data Envelopment Analysis (DEA) was subjected to the energy data of wheat producers in Punjab state, India, and technical, pure technical and scale efficiencies were calculated for farms both category wise and zone wise. The main objective was to determine the strength of the correlation between non-parametric efficiencies and indices such as energy ratio and speci...
متن کاملImproving Crop Yield and Nutrient Use Efficiency via Biofertilization—A Global Meta-analysis
The application of microbial inoculants (biofertilizers) is a promising technology for future sustainable farming systems in view of rapidly decreasing phosphorus stocks and the need to more efficiently use available nitrogen (N). Various microbial taxa are currently used as biofertilizers, based on their capacity to access nutrients from fertilizers and soil stocks, to fix atmospheric nitrogen...
متن کاملinteraction of nutrient resource and crop diversity on resource use efficiency in different cropping systems
introduction with the continuous growth of world population, degradation and ecological imbalance throughout the world, there is a need to increase agricultural production and environmental protection measures. in this respect, efforts to supply nutrients to the environment are at the head of the programs. one of the ways to approach this goal is the use of intercropping systems (najafi & moham...
