Abstract:
A field experiment was conducted during the winter season of 2019-20 and 2020-21 to study the effect on wheat production and productivity under four thermal environments (E₁:15^th November, E₂:30^th November, E₃:15^th December, E₄:30 December) and three sowing methods (M₁: Broadcast, M₂: Line sowing and M₃: Bed planting) were evaluated in a three replication with Split Plot Design. (E₁: thermal environment) recorded significantly plant height (92.78 and 91.44 cm) dry matter accumulation (1270 and 1253 g m^-2), number of tillers (429 and 420) and leaf area index (4.71 and 4.75) number of tillers (436 and 422 m^-2) spike length (9.78 and 9.5 cm), grains spike^-1 (59.33 and 53.89) and test weight (48.89 and 47.78 g) grain yield maximum (5262 and 4941 kg ha^-1) straw yield (7441 and 7594 kg ha^-1) harvest index (41.36 and 39.34). The crop sown on E₁ and method M₃ was maximum production and best treatment combination. The maximum number of tillers (430 and 421), spike length (9.54 and 9.13 cm), grain spike^-1(52.25 and 49.33) and test weight (43.75 and 42.25 g), grain yield (5050 and 4761 kg ha^-1) straw yield (7557 and 7655 kg ha^-1) harvest index (39.90 and 38.16) in M₃. The method M₃ was found significantly superior over the rest of methods.
