摘要

During the last 5 years, there has been a growing effort by the government to increase the area under maize cultivation, because this crop has ability to thrive under minimal water requirement of 400-600 mm. However, the desired success has not been achieved due to its lower productivity level owing to poor level of mechanization. Preparation of seed bed is the most drudgery operation which requires more energy and cost. To reduce the cost involved in preparation of seed bed and to complete the sowing operation in time; a zero till drill has been developed for maize crop which can sow the maize seed in paddy harvested field without any seed bed preparation. After fabrication and assembly of zero till drill, the field tests were carried out. For calculation of cost economics, the zero till drill sowing was compared with conventional method of manual dibbling. Effective field capacity of zero till drill was 0.357 ha/h, efficiency of the zero till drill was 74.3 %. Grain yield in zero tillage method was 8.5 t/ha and manual dibbling method was 7.8 t/ha. Zero till drill results in saving of production cost by 17 %, saving in time by 75 % and increase of yield by 9 % over conventional method of manual dibbling.
