Global crop improvement networks to bridge technology gaps
To ensure future food security, there is an urgent need for improved co-ordination of agricultural research. While advances in biotechnology hold considerable promise, significant technology gaps exist that may reduce their ...
Long-term consequences of tillage residue management and crop rotation on maize wheat root rot and nematode populations in subtropical highlands
Densely populated and intensively cropped, the subtropical highlands of the world have severe agricultural sustainability problems resulting from soil erosion and fertility decline. In 1991, the International Maize and ...
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 ...
Insights into genotype × tillage interaction effects on the grain yield of wheat and maize
No tillage or zero tillage (NT) is the extreme form of reduced tillage; NT with residue retention is a main component of conservation agriculture. Using a literature survey and meta-analysis, this study aimed to (i) summarize ...
Medium-term effects of conservation agriculture based cropping systems for sustainable soil and water management and crop productivity in the Ethiopian highlands
In the northern Ethiopian highlands, croplands yield extremely high volumes of storm runoff and are the major contributor to sediment load in the rivers. A medium-term tillage experiment was carried out (2005?2010) on a ...
Greenhouse gas emissions under conservation agriculture compared to traditional cultivation of maize in the central highlands of Mexico
In 1991, the International Maize and Wheat Improvement Center (CIMMYT) started a field experiment in the rain fed Mexican highlands to investigate conservation agriculture (CA) as a sustainable alternative for conventional ...
