SUMMARY
Oat (Avena sativa L.) is a popular multi-cut cereal crop among dairy farmers for green fodder in India. Every year, many new varieties of oats are released for cultivation purposes. However, limited information on their seed yield potential, yield attributes, mineral content and its uptake potentials are available. Hence, field experiments were conducted during the Rabi seasons of 2016- 17, 2017-18 and 2018-19 to evaluate 18 oats varieties. Statistical analysis of three years pooled data revealed that there was significant difference among varieties for seed yield potential. The highest yielding variety JHO 822 (14.85 q/ha), at par with OS 346 (14.16 q/ha) and check variety Kent (12.14 q/ha), recorded significantly higher seed yield in comparison to remaining oats varieties. JHO 822 (14.10) variety recorded the highest harvest index and JHO 99-2 (47.67 g) recorded the highest 1000- seed weight. Amongst all oat varieties, non-significant differences were recorded for variation in straw yield, biological yield, plant height, panicle length, tillers/metre, seed weight/panicle and seed /panicle. Crude protein, crude fat, crude fibre and acid insoluble content (%) in oats varieties varied non-significantly in seed; and in straw. NDO 1 recorded significantly higher N (2.81%) and P (0.57%) contents in seed. K content was found to be significantly higher in JHO 851 (0.73%), Mg content was recorded significantly higher in JHO 99-1 (0.24%) and JO 1 variety recorded significantly higher S content (0.23%). JHO 822 recorded significantly higher P2O5 (16.46 kg/ha), S (3.30 kg/ha) and Cu (12.59 g/ha) uptake for seed yield. N, K2O, Ca, and Mg uptake (kg/ha) for seed yield in oats varieties varied non-significantly. Similarly, oat varieties differed non-significantly amongst themselves for Mn, Fe and Zn contents (ppm) in seed.
