Quantification of greenhouse gases (GHGs) emissions from agriculture is necessary to prepare the national inventories and to develop the mitigation strategies. Field experiments were conducted during 2008-2010 at the experimental farm of the Indian Agricultural Research Institute, New Delhi, India to quantify nitrous oxide (N2O), methane (CH4), and carbon(More)
Field experiments were carried out during 1996-97 at Gulawathi, Muthiani and Salarpur Villages, IARI Farm, New Delhi and NCPP Campus, Dadri to evaluate changes in soil characteristics and growth of wheat (Triticum aestivum L.), mustard (Brassica juncea L.), lentil (Lence esculenta Moench.), rice (Oryza sativa L.) and maize (Zea mays L.) by varying amounts(More)
Four field experiments, two experiments each during winter season of 2012–2013 and 2013–2014, were conducted to evaluate effect of sowing time and four wheat cultivars on population of wheat aphids. Wheat crop was found infested with Rhopalosiphum padi and Sitobion avenae in various proportions in different experiments. During vegetative crop phase,(More)
Ammonia (NH3) emission from rice (July–October) and wheat (November–April) cropping system was measured using the chemiluminescence method at the subtropical agricultural land of Delhi, India during 2009–2010 and 2010–2011. The measurement was carried out from the canopy height (1.2–1.3 m) during the different growth stages of rice and wheat crops to(More)
Increasing temperature is likely to affect productivity of wheat and chickpea crop. A field experiment was conducted for two consecutive years with wheat and chickpea crop raised inside the temperature gradient tunnel (TGT). Results showed that high temperature reduced crop growth duration in both the crops. Days to 50 % flowering reduced by 4–5 days in(More)
