Description Cereals form the staple food of huge population of Indian sUbcontinent. These include rice, wheat, maize, barley, oats and various millets. Rice-wheat is the major crop sequence in India. It occupies an area of 10 million hectares and contributes about 60 per cent of total food grain production (Anonymous, 2002). In Himachal Pradesh, rice and wheat are grown in about 50 per cent of total cropped area and accounts for 43-49 per cent of total food grain production (Anonymous, 1998). The average productivity of this cropping sequence is 1.4 t/ha, which is very low as compared to that of adjoining states i.e. Punjab (8.74 t/ha), Haryana (7.76 t/ha) and U.P. (6.3 t/ha) (Narang and Virmani, 2001). In. addition to other reasons, the lower yields may also be attributed to inadequate and imbalanced use of plant nutrients as revealed by the present low nutrient consumption (N + P20S + K20) rate of 49.4 kg/ha and vitiated ratio of N : P20S : K20 (4.2:1.3:1) (Anonymous, 2005). Also because of poor purchasing power, farmers of Himachal Pradesh are not in a position to pay for costly chemical fertilizers, so in general, the total requirements of the hutrients of this intensive and exhaustive cropping sequence is not met.
