Abstract:
The present investigation entitled “Effect of different varieties, date of sowing and cutting management on yield attributes and yield for seed productivity of oat” was carried out at Instructional cum Research Farm, Indira Gandhi Krishi Vishwavidyalaya, Raipur (Chhattisgarh) during Rabi season of 2018-19 and 2019-20. Experiment was laid out in strip split plot design with three replications. In the experiment field was divided into vertical strips and horizontal strips further horizontal strips divided in to sub plots. In the experiment varieties, cutting management and date of sowing were evaluated for seed production of fodder oat. In this experiment two varieties: V₁-JHO-822 and V₂-RO-19 was allotted in vertical strips further three dates of sowing: D₁-Last week of October (MW-44), D₂-Second week of November (MW-46) and D₃-Last week of November (MW-48) was taken in horizontal strip and in sub plots three cutting management: C₀-No cut seed to seed, C₁-One cut at 45 DAS + seed and C₂-One cut at 60 DAS + seed was randomized. Influence of above treatments on varieties was studied for yield attributes and seed yield, feasibility of oat seed production and were computed and analyzed statistically. Significantly highest seed yield (29.87 q ha^-1) was recorded under the combination of oat variety JHO-822, when crop was sown at last week of October and one cutting was taken at 45 days after sowing and crop was left for seed production. Whereas, this combination was found at par with the combinations of variety JHO-822 and sowing at second week of November and one cut at 45 days after sowing (28.51 q ha^-1) and variety JHO-822 sown at last week of October with seed to seed where no cut (27.47 q ha^-1) was taken.
