Abstract
The technology was piloted in the Science City of Muñoz and in Guimba, Lupao and Talugtug, Nueva Ecija, with 84 farmer cooperators trained on the improved rice ratooning. Four farmers’ field days were attended by 319 participants. Five inbred and three hybrid rice varieties were ratooned. The 47 farmers ratooned NSIC Rc-222 and 20 farmers used NSIC Rc-216, seven farmers for SL-9H, four farmers for NSIC Rc-308, three farmers for NSIC Rc-10 and one farmer each for NSIC Rc-396, SL-8H and IL-29. In Science City of Muñoz, NSIC Rc-216 produced the highest yield of ratoon rice with a mean of 950 kg/ha and 820 kg/ha in Guimba followed by 660 kg/ha in Lupao and 500 kg/ha in Talugtug. For NSIC Rc-222, the highest yield was recorded in Lupao with 517 kg/ha and in Science City of Muñoz with 438 kg/ha then in Guimba with 407 kg/ha and the lowest in Talugtug with 405 kg/ha. The highest yield of NSIC Rc-308 with a mean of 783 kg/ha was recorded in Lupao followed by 352 kg/ha in Science City of Muñoz. In Guimba, NSIC Rc-396 has a mean yield of 800 kg/ha and in Talugtug NSIC Rc-10 yielded 435 kg/ha. Hybrid rice SL-8H and SL-9H of Science City of Muñoz which were ratooned for the first time produced a mean yield of 230 kg/ha and 238 kg/ha respectively. In Lupao, IL-29 yielded 632 kg/ha. In all the pilot sites, the NSIC Rc-216 with an average yield of 950 kg/ha obtained a gross income of Php 16,910.00 at a price of Php 17.80 per kg. The total expenses in ratooning was Php 8,112.00/ha. The value cost ratio was 1.92. The breakeven yield of 494.97 kg/ha is an implication that rice ratooning is profitable.
