Description |
Maize-wheat is an important cropping sequence of Himachal Pradesh, contributing about 85 per cent of the total food grain production in the state. The average yield of these crops, however, is low, amounting to 1.61 and 1.52 t ha-1 against the national average of 1.64 and 2.62 t ha-1 for maize and wheat, respectively (Anonymous, 2004). Fertilizer application is an indispensable and integral part of modern intensive crop production systems to supplement soil nutrients removed by the crops. Due to the paucity of organic sources, the reliance of farmers on the inorganic fertilizers has increased. The fertilizer consumption in India during the last about five decades increased from 0.07 million tonnes (1950-51) to 16.8 million tonnes (2003-04). To sustain soil productivity, it is essential that plant nutrients are supplied in a balanced ratio.
