Breeding resilient and productive genotypes adapted to drought-prone rainfed ecosystem of India
Drought is the predominant cause of yield reduction in rainfed rice production systems, but until recently, little systematic effort has been made to breed drought-tolerant cultivars. The complex nature of drought tolerance, ...
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 ...
Drought susceptibility of modern rice varieties : an effect of linkage of drought tolerance with undesirable traits
(Nature Publishing, 2015)
Green Revolution (GR) rice varieties are high yielding but typically drought sensitive. This is partly due to the tight linkage between the loci governing plant height and drought tolerance. This linkage is illustrated ...
Implications of genotype × input interactions in breeding superior genotypes for favorable and unfavorable rainfed upland environments
Resource-poor farmers in India cultivate upland rice as a subsistence crop in poor soil with minimum inputs, often applying little or no fertilizer and controlling weeds by hand. Consequently, upland rice yields are very ...
Developing aerobic rice cultivars for water-short irrigated and drought-prone rainfed areas in the tropics
Aerobic rice is a production system in which rice is direct seeded and grown in nonpuddled and nonflooded aerobic soils. Aerobic rice varieties need to be developed to cope with the increasing water scarcity in tropical ...
Precision nutrient management in conservation agriculture based wheat production of Northwest India: Profitability, nutrient use efficiency and environmental footprint
In the high-yielding wheat production systems in Northwest (NW) Indo-Gangetic Plains of India, intensive tillage operations and blanket fertilizer recommendations have led to high production costs, decreased nutrient use ...
Optimizing intensive cereal-based cropping systems addressing current and future drivers of agricultural change in the northwestern Indo-Gangetic Plains of India
Increasing scarcity of resources (labour, water, and energy) and cost of production, along with climate variability, are major challenges for the sustainability of rice-wheat system in the northwesten Indo-Gangetic Plains ...
Operational manual for multi-crop zero till planter
(CIMMYT; CSISA; IRRI; NASC, 2012)
Multidimensional impact assessment of zero tillage technology on wheat productivity in Haryana
The farmer’s participatory approach proved to be accurate guide for zero tillage technology adoption by farmers within different districts not only in Haryana, India, but also in other major wheat producing states of the ...
