Abstract:
A field experiment was conducted to evaluate the performance of seven rice varieties collected from IGKV Raipur namely, Chandrahasni, Swarna, zinc Rice, Protezinc, DRR dhan 48, Madhuraj 55 and Rajeshwari. The experiment was laid out in a Randomized Block Design with three replications. Observation was recorded on 30 DAT, 60 DAT, 90 DAT and at harvest on parameters like, Growth parameters viz. Plant height, Number of tillers/plant, Number of leaves/plant, LAI, CGR and RGR. Yield parameters viz. Number of panicles/m², Panicle length, Number of grains/panicle and Test weight. Grain yield, Straw yield and Harvest index was also recorded. Result obtained as the plant height at harvest was tallest of Madhuraj 55 (114.1 cm), maximum no. of tillers/plant was produced by Rajeshwari rice variety (19.8), maximum number of leaves/plant was produced highest by Rajeshwari (44.0) and maximum LAI, CGR and RGR was registered by Rajeshwari variety (4.74, 9.54 and 0.060 respectively). All the yield parameters were recorded maximum by Rajeshwari rice variety followed by Swarna and the poorest yield attributing characteristics was registered by Protezinc. Grain yield, straw yield and harvest index was comparatively higher in Rajeshwari (65.6 q/ha, 86.4 q/ha and 43.2% respectively) followed by Swarna rice variety (61.1 q/ha, 85.0 q/ha and 41% respectively).
