Comparison of parachute, line and traditional rice transplanting methods at farmer's field in rice growing area.

摘要

The parachute transplanting method of rice, as compared to line transplanting and farmer's method of random transplanting, was studied at 10 different locations in Pakistan (Kamonki, Wazirabad, Daska, Pasroor, Gujranwala, Sialkot, Lahore, Hafizabad and Sheikhupura), in 2003 and 2004. Super Basmati was used as the test cultivar. Yield and yield components of the 3 transplanting techniques, averaged across 10 locations, were significantly different from each other. The line transplanting gave the highest yield of 4.34 t/ha, followed by the parachute transplanting method. The conventional transplanting method practiced by farmers gave the minimum yield of 3.79 t/ha. The line transplanting also produced maximum value for number of tillers per plant (25.30) and number of grains per panicle (65.50). In the parachute transplanting method, the plant population (213 530) was maximum, followed by line transplanting and farmer's practice of random transplanting.
