Assessing the impact of adaptive agricultural research on accelerating technology deployment: The case of zero tillage wheat in India
A critical assumption in the impact assessment of an agricultural R&D effort is whether the effort in question has a substitute ? that is, whether the innovation would also happen under other settings. This paper takes the ...
Conservation agriculture in Central Asia - What do we know and where do we go from here?
Rainfed and irrigated agricultural systems have supported livelihoods in the five Central Asian countries (CAC) for millennia, but concerns for sustainability and efficient use of land and water resources are long-standing. ...
Global warming potential of agricultural systems with contrasting tillage and residue management in the central highlands of Mexico
Conservation agriculture based on (1) minimal soil movement, (2) retention of rational amounts of crop residue, (3) economically viable crop rotations restores soil fertility. Conservation agriculture improves soil ...
Molecular characterization of soil bacterial communities in contrasting zero tillage systems
It is well known that agricultural practices change the physical and chemical characteristics of soil. As a result, microbial populations can also be affected. The aim of this study was to analyze the effect on soil bacterial ...
Can productivity and profitability be enhanced in intensively managed cereal systems while reducing the environmental footprint of production? Assessing sustainable intensification options in the breadbasket of India
In the most productive area of the Indo-Gangetic Plains in Northwest India where high yields of rice and wheat are commonplace, a medium-term cropping system trial was conducted in Haryana State. The goal of the study was ...
Made in Bangladesh : scale-appropriate machinery for agricultural resource conservation
An open-source publication targeted to machinery manufacturers, engineers, researchers and development practitioners, this book describes and provides technical designs for small-scale agricultural machinery developed or ...
Conservation agriculture for small holder rainfed farming: Opportunities and constraints of new mechanized seeding systems
Small holder farmers in rainfed agriculture believe that soil tillage is needed to maximize crop yields. However, as cropping intensity, and hence tillage intensity, increases there may be a decline in particular physical, ...
