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 ...
Herbicide options for effective weed management in dry directseeded rice under scented rice-wheat rotation of western Indo- Gangetic Plains
Farmers' participatory field trials were conducted at Madhuban, and Taraori, the two participatory experimental sites/locations of the Cereal Systems Initiative for South Asia (CSISA), a collaborative project of IRRI and ...
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 ...
Gender and inorganic nitrogen : what are the implications of moving towards a more balanced use of nitrogen fertilizer in the tropics?
(Taylor & Francis, 2017)
For agriculture to play a role in climate change mitigation strategies to reduce emissions from inorganic nitrogen (N) fertilizer through a more balanced and efficient use are necessary. Such strategies should align with ...
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 ...
Behaviour of Quality Protein Maize (QPM) genotypes under well irrigated and water stress conditions in subtropical climate
Drought or water stress is one of the prime problems affecting production of maize at global level. A major ob¬jective of QPM breeding programs in semi arid tropics or subtropical climatic conditions is to increase genetic ...
Assessment of the nitrogen management strategy using an optical sensor for irrigated wheat
Blanket fertilizer nitrogen (N) recommendations for large irrigated wheat tracts lead to low N-use efficiency due to field-to-field variability in soil N supply and seasonal variability in yield. To achieve high N use ...
Double no-till and permanent raised beds in maize-wheat rotation of north-western Indo-Gangetic plains of India: Effects on crop yields, water productivity, profitability and soil physical properties
Excessive pumping of groundwater over the years to meet the high water requirement of flooded rice crop and intensive tillage have threatened the sustainability of irrigated rice-wheat system (RWS) in the Indo-Gangetic ...
Nutrient management in wheat: current scenario, improved strategies and future research needs in India
Wheat (Triticum aestivum L) is the second most important staple food and meets about 61% of the protein requirement of the India. The introduction of new high yielding varieties coupled with chemical fertilizer use and ...
