Abstract:
A field experiment entitled “Effect of sowing windows and irrigations on yield and economics of wheat” was conducted at Agronomy Farm, College of Agriculture, Nagpur during rabi season of 2020-21. The experiment was laid out in Split Plot Design with 12 treatment combinations and replicated thrice. The treatments consisted of four sowing dates viz., 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 i.e., 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 grain and straw yield (3154 and 3973 kg ha^-1) of wheat. Grain and 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) gave significantly highest grain yield of wheat. Gross monetary returns and net monetary returns were significantly higher with sowing in 48 MW (S₁) with six irrigations (I₃) after harvest over rest of the respective treatments.
