Description The rice-wheat is the most extensive and traditional cropping system in India which is the main stay of cereal food production in the country. It has been observed that intensive agricultural practices in high yielding rice-wheat cropping system have resulted in numerous problems like deterioration of soil health, pollution hazard and depletion of resources and stagnation in crop production and productivity. This system brings together conflicting and complementary practices. At present this system operates at low yield because of inadequate and imbalanced nutrients and inappropriate soil and water management. In general in India and particular in Himachal Pradesh, these two crops are major food grain crops. The average productivity of rice and wheat crops in India is 2.07 t/ha and 2.71 t/ha, respectively (Anonymous, 2004). In Himachal Pradesh, wheat occupies first position in acreage covering about 361.0 thousand-hectare area, whereas in Kharif season the rice crop is sown on 81.3 thousand hectare area. The average productivity of rice and wheat in Himachal Pradesh is 1.48 t/ha and 1.38 t/ha, respectively (Anonymous, 2004). This indicates a lot of scope for increasing the productivity of these crops. Therefore, technological change is necessary to meet the increasing demand of food for growing population.
