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 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 ...
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 ...
Response of maize (Zea mays L.) secondary growth parameters to conservation agriculture and conventional tillage systems in Zimbabwe
(Canadian Center of Science and Education, 2016)
Previous, research focused mainly on the effects of conservation agriculture (CA) and conventional practices (CP) on crop yield mostly. A study was conducted at five sites in Zimbabwe from 2012 to 2014 to investigate effects ...
Soil organic carbon changes after seven years of conservation agriculture in a rice–wheat system of the eastern Indo-Gangetic Plains
Sequestration of soil organic carbon (SOC) is an important strategy to improve soil quality and to mitigate climate change. To investigate changes in SOC under conservation agriculture (CA), we measured SOC concentrations ...
Effect of different mulching materials on maize growth and yield in conservation agriculture systems of sub-humid Zimbabwe
(AIMS Press, 2016)
The introduction of conservation agriculture (CA) for smallholders increased the competition for crop residues between crop and livestock enterprises of the mixed smallholder farming system. Smallholders practicing CA have ...
Assessing soil properties and nutrient availability under conservation agriculture practices in a reclaimed sodic soil in cereal-based systems of North-West India
(Taylor & Francis, 2018)
Soil quality degradation associated with resources scarcity is the major concern for the sustainability of conventional rice-wheat system in South Asia. Replacement of conventional management practices with conservation ...
Groundwater management in Bangladesh : an analysis of problems and opportunities
Increased groundwater accessibility resulting from the expansion of deep and shallow tube wells helped Bangladesh attain near self-sufficiency in rice, with national output increasing over 15 million tons in the last two ...
Comparative performance of conservation agriculture and current smallholder farming practices in semi-arid Zimbabwe
Conservationagriculture (CA) is currently promoted in sub-humid and semi-arid areas of sub-Saharan Africa as a means to increase crop water use efficiency and stabilize yields. In this study, conducted during three consecutive ...
