Abstract: |
Rice is an important crop ofTiflestern Terai, but rice .yields are low compared to its potential. To improve rice yield, different field experiments were conducted in three different sites namely Sand:2, Mahilawar and Burrohiya, command area of National Whea~ Research Program, Bhairahawa. The activities were concentrated on rice varietal improvement; agronomic aspects and validation of improve technologies. In coordinated farmers' field trial at Mahilwar site, BPI 3-2 produced significantly higher grain yield (4600 kglha) than rest of the tested genotypes, whereas genotypes IR 58115-103-3-1-1 and BR 4684-13-1-1-6-3 were at par to each other and were significantly higher than PSBRC-2 and Sabitri. However at Burrohiya site, genotypes B6144F-MR-6 and Radha-4 were at par to each other and produced significantly higher grain yield than rest of the tested genotypes. In Coordinated Farmers Field Trial of aromatic rice, highly significant variation for grain yield was recorded which raged .from 3600 to 4300 kglha at Mahilwar site and 4000 to 6166 kg/ha at Burrohiya site. At Burrohiya site, genotype CNTLR85033-9-3-1-1 produced significantly highest grain yield (61 66 kg/ha) amongst the tested genotypes. The yield peiformance of rice genotypes tested in FAT at Sanda site, the mean grain yield of genotypes NR 1824 and BR425-189-1-6-2-1 showed higher (4300 and 4367 kglha respectively) yield than other tested genotypes. Whereas at Mahilwar site, genotype BR 802 produced the highest mean grain y ield (4000 kg/ha) and was liked by the farmers. Under rainfed low land condition at Burrohiya site, genotypes BR 425-189-1-6-2-1 produced the highest mean grain yield (5225 kg/ha) and was preferred by the farmers. In study of System of Rice Intensification (SRI), the mean grain yields of Radha-4 at sanda was higher (5266.5 kglha) compared to farmers practice (3950 kglha). At Bun·ohiya site, variety Sabitri produced higher grain yield (7055 kglha) compared to fanners practice (4000 kg/ha.). Result of Frontline Demonstration conducted in deferent environment showed that with recommended practices higher grain yield up to 5600 kglha could be achieved with genotype B6144-FMR6-2 under farmer's field condition. |
