JaganmohanraoAbstract Theon-farm demonstration was conducted in farmersâ field of Khammam District, Professor Jayashankar Telangana State Agricultural University, Telangana state during kharif season of 2018, 2019, and 2020. Theon-farm demonstration results revealed that the significant improvement on both growth and yield attributes continuously in three (2018-2020) years and pooled respectively. The maximum growth and yield in terms of plant height (94.4, 97.6, 93.6 and 95.2 cm), no of effective tillers plant-1 (16.6, 17.4, 15.7 and 16.5), no of hills m-2 (25.0, 26.0, 25.0 and 25.3), no of panicles m-2 (346, 387, 321 and 351.3), no of filled grains (188, 193, 179 and 186.6), test weight (14.8, 15.7, 14.8 and 15.1), grain yield (6836, 7416, 6161 and 6804 kgha-1), straw yield (8874, 9120, 8537 and 8844 kg ha-1), harvest index (43.5, 44.8. 41.9 and 43.4) and economics were higher with machine transplanting method than farmersâ practice. Continuously in three years. The lowest plant height (86.7, 88.4, 85.3 and 86.4 cm), no of hills m-2 (21,22,22 and 21.6) no of panicles m-2 (258, 265, 245 and 256), no of filled grains (169, 176, 172 and 172), test weight (14.7, 14.9, 14.8 and 14.8), grain yield (6577, 6648, 5317 and 6180 kg ha-1), straw yield (8612, 8732, 8456 and 8600 kg ha-1), were recorded in farmersâpractice under delayed transplanting condition with considerable limitations of aged nursery. |
