Straw management, crop rotation, and nitrogen source effect on wheat grain yield and nitrogen use efficiency
Nitrogen fertilizer management from different sources and annual crop rotations are important components of wheat (Triticum aestivum L.) production systems, especially where air and soil quality issues have prompted a ...
The natural abundance of 13C with different agricultural management by NIRS with fibre optic probe technology
In the present study the natural abundance of 13C is quantified in agricultural soils in Mexico which have been submitted to different agronomic practices, zero and conventional tillage, retention of crop residues (with ...
Conservation agriculture in maize- and wheat-based systems in the (Sub)tropics: Lessons from adaptation initiatives in South Asia, Mexico, and Southern Africa
Conservation agriculture's underlying principles—minimal soil disturbance, soil cover and crop rotation—are increasingly recognized as essential for sustainable agriculture. This article summarizes three contrasting cases ...
Wheat genetic resources enhancement by the International Maize and Wheat Improvement Center (CIMMYT)
The International Maize and Wheat Improvement Center (CIMMYT) acts as a catalyst and leader in a global maize and wheat innovation network that serves the poor in the developing world. Drawing on strong science and effective ...
Influence of permanent raised bed planting and residue management on physical and chemical soil quality in rain fed maize/wheat systems
Densely populated, intensively cropped highland areas in the tropics and subtropics are prone to erosion and declining soil fertility, making agriculture unsustainable. Conservation agriculture in its version of permanent ...
Using NDVI and soil quality analysis to assess influence of agronomic management on within-plot spatial variability and factors limiting production
Crop growth and yield are the result of the efficiency of the chosen agricultural management system within the boundaries of the agro-ecological environment. Linking spatial variability in crop performance to differences ...
