To ameliorate the ill effects of traditional rice-wheat cropping system efforts have been made to develop several resource conservation technologies. Conventional method of wheat sowing requires intensive pre-planting cultivation, which are labour, time and energy intensive. The field experiment was conducted at Govind Ballabh Pant University of Agriculture and Technology, Pantnagar during rainy season of 2005-06 to winter season of 2006-07. Maximum mean grain (4 237 kg/ha) and straw (6 235 kg/ha) yields of wheat were obtained from direct-seeded rice plots. Nutrient uptake (NPK) by the wheat crop was highest under direct-seeded rice due to rice establishment methods. Maximum mean grain (4 535 kg/ha) and straw (6 423 kg/ha) yields were obtained under zero till. The mean wheat grains/spike under zero till drill wheat was 0.79, 6.93 and 4.09% more than that of strip till drill, bed planted and conventional wheat, respectively. Zero till drill wheat exhibited significantly higher nutrient uptake than that of conventional, bed planted and strip till drill wheat.
