Low-Input Cropping Systems and Nitrogen Fertilizer Effects on Crop Production: Soil Nitrogen Dynamics and Efficiency of Nitrogen Use in Maize Crop
Soil N is a major factor limiting crop production in maize-based agriculture in the tropics. In this study, soil N dynamics and efficiency of N use by maize was investigated in five cropping systems (CSs) over two annual cropping phases. The CSs comprised cereal-legume (CS1, CS2, CS3), cereal-cereal (CS4) and cereal-bare fallow (CS5) rotations with three rates of N fertiliser application to mai...
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...
متن کاملnteraction of nutrient resource and crop diversity on resource use efficiency in different cropping systems
introduction conventional operations in fields, soil and water management are not efficient and loss of and damage to the environment are considerable (lal, 2000). crop diversity and understanding the complex interactions between environmental and socioeconomic factors are approaches to make better use of limited resources (tengberg et al., 1998). the most diverse ecosystems have a higher produ...
متن کاملIntegrative impacts of soil tillage on crop yield, N use efficiency and greenhouse gas emission in wheat-corn cropping system
Wheat-corn cropping system is one of the most important grain production systems in theworld. However, the integrative impacts of soil tillage on crop yield, N use efficiency (NUE)and greenhouse gases (GHGS) emissions are not well documented in this system. Thus, a twoyear field experiment was carried out in a typical wheat-corn cropping system with four tillageregimes during the wheat season, ...
متن کاملIntegrating crop growth simulation and remote sensing to improve resource use efficiency in farming systems
This study investigated the scope and constraints for integrated use of mechanistic crop growth simulation models and earth observation techniques. Integration of highquality crop growth models and information derived from earth observations can contribute to improved use of resources, reduced crop production risks, reduced environmental degradation, and increased farm income. In the past, both...
