Operational manual for multi-crop zero till planter
(CIMMYT; CSISA; IRRI, 2012)
A comparative analysis of rice-wheat systems in Indian Haryana and Pakistan Punjab
Intensive irrigated rice-wheat production systems have converted the north-west Indo-Gangetic Plains into South Asia's cereal basket. Their strategic importance is undermined by a slowdown in productivity growth linked to ...
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 ...
The paradox of limited maize stover use in india's smallholder crop-livestock systems
Cereal residues are an important feed source for ruminants in smallholder crop-livestock systems in the (sub)tropics. In many areas of India maize is a relatively new cash crop where farmers and development agents alike ...
Integrated nutrient management in Quality Protein Maize (Zea mays) planted in rotation with wheat (Triticum aestivum): Effect on productivity and nutrient use efficiency under different agro-ecological conditions
Field experiments were conducted during two consecutive years 2007 and 2008 at seven locations, viz. Ambikapur, Bahraich, Banswara, Chhindwara, Ranchi, Udaipur and Varanasi of different agro-ecologies to evaluate the effect ...
Characterization of the effect of a QTL for drought resistance in rice, qtl12.1 , over a range of environments in the Philippines and eastern India
A large-effect QTL for grain yield under drought conditions (qtl12.1) was reported in a rice mapping population derived from Vandana and Way Rarem. Here, we measured the effect of qtl12.1 on grain yield and associated ...
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, ...
Zero tillage impacts in India's rice-wheat systems: A review
To date, the most widely adopted resource conserving technology in the Indo-Gangetic Plains (IGP) of South Asia has been zero-tillage (ZT) wheat after rice, particularly in India. The paper reviews and synthesizes the ...
