Influence of different dates of sowing and varieties on growth and yield attributes in wheat

摘要

The present study was carried out during Rabi season of 2019-2020, at the Chandra Shekhar Azad University of Agriculture and Technology, Kanpur, Uttar Pradesh, with the objective to study the effect of different sowing dates and varieties on growth attributes, yield attributes and yield, and to find best treatment combination in terms of economics. The experiment was carried out in split plot design with three different dates as main plot treatments and four varieties as subplot treatments with fourreplications. Among the growth parameters plant population (number ofplants per m2) was recorded at initial stage and plant height (cm) was recorded at different phenophases ofwheat. The plant height was significantly higher at all phenophases of wheat on early date of sowing i.e. 15th November than late dates of sowing and the interaction was found significant with plant height at milking, dough stage and maturity under different dates of sowing and varieties. Among the yield attributes and yield, number of spikelets per ear and grain weight(g), biomass yield (kg per ha), grain yield (kg per ha), straw yield (kg per ha) were recorded and analysed. It was found that all yield attributes and yield recorded were found significantly higher with early dateof sowing i.e 15th November. Early date of sowing i.e crop sown on 15th November produced significantly higher grain yield with HD 2967 variety over other dates of sowing and varieties. In order to find best treatment combination in terms of economics found that the variety HD 2967 sown on early date of sowing i.e. 15th November was economically feasible.
