| dc.description.abstract | A field experiment was conducted entitled “Performance of traditional scented rice (Oryza sativa L.) varieties under organic mode of cultivation” at NEBCRC, GBPUAT at Pantnagar during Kharif 2020 to evaluate the performance of ten traditional scented rice varieties namely Kubri Mamhani, Kudrat-5, Chinar-20, Kesho Pohu, DRK, Kudrat-5, Pusa1121, Type-3, Taraori and Tilak Chandan under organic mode of cultivation in the Organic Farming Block. The soil of Experimental site with silty clay loam in texture, 0.571% organic carbon, 7.33 pH, 157.8 kg/ha in available N, 15.6 kg/ha in available P and 221.1 kg/ha in available K. The transplanting was done at 25cm × 12.5 cm spacing, using two seedlings per hill. Rice crop was fertilized with green manuring (Sesbania) and 2.5 t vermicompost ha/ha as top dressing. Variety Taraori was the tallest (151.7 cm) and Kudrat-1 the shortest (99.0 cm). The culm height ranged from 66.0 cm (Chinar-20) to 139.3 cm (Type-3). Variety Kudrat-1 possessed the maximum thickness of lower, middle and upper portion of the culm. The earliest days to 50% flowering was observed for variety Chinar-20 (77) and longest days for Kubri Mamhani and DRK. The maximum tillers/m2 (273), grain weight/panicle (1.89 g) with a test weight of 15.5 g. Variety Kudrat-1 had the maximum number of grains/panicle (281) followed by Kudrat-5 (202). The grain, straw and harvest index were found the highest with variety Kudrat-5 followed by Kudrat-1. The economic returns were also with these two varieties. The N, P and K contents and their uptake in grains and straw exhibited a variable trend among different scented rice varieties. DUS characteristics were determined for all the varieties. The head rice recovery was the highest in case of variety Kudrat-1 (78.8%) followed by Kudrat-5 (76.4%). Therefore, under organic mode of cultivation, variety Kudrat-5 has been found suitable for tarai region. | en_US |
