Studies on the economics of alternative wheat establishment methods and weed management practices.

摘要

A field experiment was conducted during the winter seasons of 2002-03, in Pantnagar, Uttar Pradesh, India, to evaluate the economics of different establishment methods (conventional tillage, zero tillage, strip till drill and bed planting) and weed management practices (hand weeding at 30 and 50 days after sowing (DAS), isoproturon at 1 kg/ha at 30 DAS, clodinafop-propargyl [clodinafop] at 0.06 kg/ha at 30 DAS and weedy control) in wheat. Conventional tillage + isoproturon recorded the highest net return (Rs. 21 089/ha), followed by strip till drill + isoproturon (Rs. 21 074/ha), conventional tillage + hand weeding (Rs. 20 725/ha), and zero tillage + isoproturon (Rs. 20 502/ha). Strip till drill + isoproturon and zero tillage + isoproturon recorded the highest benefit:cost ratios of 2.09 and 2.05, respectively..
