Abstract:
In the rabi season of 2019-2020, an experiment entitled “Studies on growth and yield of wheat (Triticum aestivum L.) genotypes under irrigated condition” was carried out at the farm of Wheat Research Unit, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola (M.S.). The treatments consisted of 15 treatment combinations comprised of three irrigation levels i.e., two irrigations (CRI, Flowering), four irrigations (CRI, Tillering, Flowering and Milk stage), six irrigations (CRI, Tillering, Jointing, Flowering, Milk and Dough stage) and five wheat genotypes viz., AKAW-4627, AKAW- 4832, WSM 109-4, PDKV SARDAR, and PDKV WASHIM. The experiment was laid out in a factorial randomized block design with three replications. The soil was clayey with a pH of 7.64 and 212.72, 22.27 and 368.45 kg ha^-1 of available N, P and K, respectively. When wheat crop was irrigated with six irrigations (CRI, Tillering, Jointing, Flowering, Milk and Dough stage) instead of four irrigations (CRI, Tillering, Flowering, Milk stage) and two irrigations (CRI, Flowering), the growth and yield attributes were significantly improved. Grain yield was significantly higher with six irrigations (CRI, Tillering, Jointing, Flowering, Milk and Dough stage). Genotype AKAW-4627 performed better than other genotypes in terms of plant height (cm), numbers of functional leaves plant^-1, leaf area plant^-1 (dm2), number of tillers plant^-1, dry matter accumulation plant^-1(g), weight of spike (g), number of spike plant^-1, number of spikelet spike^-1, number of grain spike^-1, weight of grains spike^-1(g), test weight (g), grain yield (kg ha^-1), straw yield (kg ha^-1), biological yield and harvest index (%).
