Abstract:
A field experiment conducted at Agronomy Farm, College of Agriculture, Nagpur during rabi season of 2020-21 to evaluate the effect of sowing windows and irrigations on growth and yield of wheat. The experiment was laid out in Split Plot Design with 12 treatment combinations replicated thrice. The treatments consisted of four sowing dates i.e., 48 MW – 26 Nov. to 2 Dec. (S₁), 49 MW – 3 Dec. to 9 Dec. (S₂), 50 MW – 10 Dec to 16 Dec (S₃) and 51 MW – 17 Dec. to 23 Dec. (S₄) combined with three irrigation levels at different growth stages viz., four irrigation (CRI, late tillering, late jointing, and flowering) (I₁), five irrigation (CRI, late tillering, late jointing, flowering and milking stage) (I₂) and six irrigation (CRI, late tillering, late jointing, flowering, milking and dough stage) (I₃). Results revealed that, sowing of wheat in 48 MW (S₁) recorded significantly higher growth viz. length of spike (7.18 cm), number of grains spike^-1 (36.19), grain weight plant^-1 (6.49 g) and test weight (38.87 g) along with grain, straw yield (3154 and 3973 kg ha^-1) of wheat. Growth characters viz. length of spike (7.29 cm), number of grains spike^-1 (34.60), grain weight plant^-1 (6.59 g) and test weight (38.93) along with grain, straw yield (2966 and 3905 kg ha^-1) of wheat were also significantly higher with application of six irrigations (I₃) at harvest compared to rest of the number of irrigations. Combination of sowing 48 MW (S₁) with six irrigations (I₃) recorded significantly highest grain yield of wheat.
