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 ...
Crop response and economics of phosphorus fertiliser application in rice, wheat and maize in the Indo-gangetic plains
Phosphorus (P) is one of the major essential plant nutrients. Physiological processes and yield of cereals are adversely affected in soils deficient in phosphorus. Phosphorus deficiency is widespread in Indian soils and ...
Economics of potassium fertiliser application in rice, wheat and maize grown in the indo-gangetic plains
Potassium (K) fertiliser cost has increased considerably over the past three years. The sharp increase in price has raised doubts about the profitability of potassium application in cereals where the Minimum Support Prices ...
Economics of nitrogen fertiliser application in rice, wheat and maize grown in the indo-gangetic plains
Nitrogen (N) is a key factor for cereal production in India. N is predominantly supplied to the plants through fertiliser application. The average response to applied fertiliser N has been declining steadily over the past ...
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, ...
