| dc.description.abstract | An investigation entitled “Growth and yield studies in newly developed wheat varieties under the influence of fertilizers and growth regulators” was conducted during Rabi 2021-22 at Research Farm, Department of Agronomy, CCS Haryana Agricultural University, Hisar. The field experiment was carried out in Split split plot design with eighteen treatment combinations viz., two varieties levels in the main plot, three fertilizer levels in the subplots (F1:100, F2:125 and F3:150 per cent RDF of NPK) and three growth regulator levels in sub sub plots (GR1 : Lihocin at 0.2% + 0.1% Folicur at 55 DAS (jointing stage) and 80-85 DAS (Flag leaf), GR2 : Lihocin at 0.4% + 0.1% Folicur at 55 DAS (jointing stage) and 80-85 DAS (Flag leaf) and GR3 : Control (no spray) replicated thrice. The results revealed that plant height at 60, 90 and 120 DAS was significantly reduced by both the growth regulators i.e., GR1 and GR2. Dry matter and tillers per metre row length was significantly influenced by growth regulator GR1. Fertilizer level F3 improved the tillers per metre row length at 30, 60, 90 and 120 DAS whereas in plant height at 60, 90 and 120 DAS. At growth regulator GR1, days to first node (51.7), days to jointing (71.8), days to heading (83.7), days to flowering (96.8), days to milking (110.6 days ) and days to maturity (135 days) came earlier as compared to GR3 (57.5, 76.6, 89.7, 103.8, 116.1 and 140.3 days). Maximum grain yield (5,585 kg ha-1), biological yield (19,127 kg ha-1) and straw yield (13,541 kg ha-1) was recorded at GR2. Maximum BC ratio (2.35 and 2.42) was estimated under fertilizer level F3 and growth regulator GR2. Based on the results achieved in the study, it can be inferred that both the newly developed wheat varieties of wheat i.e., DBW 303 and WH 1270 are at par in terms of yield (5,349 kg ha-1 and 5,454 kg ha-1) | en_US |
