Sustainable crop intensification through surface water irrigation in Bangladesh? A geospatial assessment of landscape-scale production potential
Changing dietary preferences and population growth in South Asia have resulted in increasing demand for wheat and maize, along side high and sustained demand for rice. In the highly productive northwestern Indo-Gangetic ...
Conservation agriculture in southern Africa: advances in knowledge
(Cambridge University Press, 2015)
The increasing demand for food from limited available land, in light of declining soil fertility and future threats of climate variability and change have increased the need for more sustainable crop management systems. ...
Does the use of atrazine in maize grown under conservation agriculture adversely affect soybean productivity in maize-soyabean rotation in Zimbabwe?
(Canadian Center of Science and Education, 2014)
Weed management challenges in the early years of conservation agriculture (CA) adoption may require the use of herbicides for farmers to realise the immediate benefits of CA practices. The objective of this study was to ...
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, ...
Layering precision land leveling and furrow irrigated raised bed planting: Productivity and input use efficiency of irrigated bread wheat in indo-gangetic plains
Stagnating yield and declining input use efficiency in irrigated wheat of the Indo-Gangetic Plain (IGP) coupled with diminishing availability of water for agriculture is a major concern of food security in South Asia. The ...
Conservation agriculture in cereal systems of south Asia: Nutrient management perspectives
In past, green revolution has paid dividends through impressive agricultural growth, which helped to keep balance between demand and supply in the past four decades. But, the real challenges have surfaced in the recent ...
Impact of ridge-furrow planting in Pakistan : empirical evidence from the farmers field
Wheat is planted through the broadcast method on 7.8 million ha and irrigated through low-efficiency flood basin irrigation methods. With decreased water availability, there is a need to adopt water use efficient planting ...
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 ...
Earthworm activity and soil structural changes under conservation agriculture in central Mexico
Crop residue mulching combined with zero tillage and crop rotation, known as conservation agriculture (CA), is being promoted as an alternative system to revert soil degradation in maize-based farming in the central highlands ...
Weedy rice: An emerging threat for direct-seeded rice production systems in India
Rice is an important cereal crop in India for food security. Conventional practices for rice production (puddled transplanting) are labour-, water-, and energy-intensive. All of these resources are becoming increasingly ...
