Abstract:
The experiment was conducted at Instructional cum Research Farm, Indira Gandhi Krishi Vishwavidyalaya, Raipur (Chhattisgarh) during Rabi season of 2018-19 and 2019-20 to study “The combined effect of varieties, sowing techniques and seed rate on oat seed production” was carried out in strip split plot design with three replications in clay (Vertisols) soil, locally known as Kanhar. In this experiment two varieties: V₁ - JHO-822 and V₂ - JO-1 was allotted in vertical strips further two sowing methods: M₁ -Line sowing and M₂-Broadcasting method was taken in horizontal strip and in sub plots three seed rates: S₁-80 kg ha^-1, S₂- 90 kg ha^-1 and S₃-100 kg ha^-1 was randomized. Recommended dose of fertilizer of 120:60:40 N: P₂O₅: K₂O ha^-1 was applied. Nitrogen was applied in two splits, 50 percent at basal and 50 percent after first cut. Varieties, sowing methods and seed rate had significant effect (p<0.05) on the yield parameters. Two years pooled data analysis results revealed that significantly higher seed yield was recorded under the variety JHO-822 (30.68 q ha^-1), when crop was sown inline sowing (30.75 q ha^-1) with 90 kg ha^-1 seed rate (31.47 q ha^-1). Statistically no significant difference was observed among all the interaction effects.
