اثر تناوب خاکورزی و مدلهای کاشت و مدیریت بقایای گیاهی بر تغییرات میزان مصرف انرژی و کارایی مصرف آب آبیاری در گندم در نظام کشت سویا–گندم

In Indo-Gangetic Plain Zone of India the population of people and cost of cultivation are increasing and in other hand water table and resources is decreasing. The studies were conducted to assess the suitability of conservation tillage, vis-a-vis conventional tillage and crop establishment techniques, viz. bed planting vis-a-vis flat planting in the recently emerging soybean-wheat cropping system in the region. The experiment was laid out in split plot design with three replication and 16 treatments in 2010-12 on farm research of Indian Agricultural Research Institute, New Delhi. Cultivation of wheat in ZT and control treatment in application of crop residue shown higher energy use-efficiency over other treatments. Raised-bed system along with ZT and CT has given higher water use-efficiency compared to flat-bed system. In general application of crop residue for conserving moisture has beneficial effect but in case of saving water the differences was negligible. However methods of crop establishment save water about 312.6 kg/ha-cm. The sequential tillage did not have effect of water saving but in case of energy saving reverse trend was observed.
