Abstract:
The experiment was conducted at Zonal Agricultural Research Station, Vishweshwaraiah canal. Farm, Mandya during rabi 2015-16 to know the effect of time of sowing and levels of nitrogen on growth and yield of fodder oats. The experiment was laid out in RCBD with factorial concept with three replication. The experiment consisted; four different times of sowing, S₁-First fortnight of October, S₂- Second fortnight of October, S₃-First fortnight of November, S₄- Second fortnight of November and three nitrogen levels (N₁-75, N₂-100 and N₃-125 Kg N per hectare). The results revealed that, sowing of fodder oats during second fortnight October significantly recorded higher plant height (133.4 cm), dry matter accumulation (172.4 g /0.5m^-1 row length) and total number of seeds panicle^-1 (58.5/ 0.5m^-1 row length), seed yield (20.2 q ha^-1), straw yield (61.6 q ha^-1), net returns (Rs. 30,574 ha^-1) and B:C ratio (2.3) over other time of sowing. Application of 125 N kg ha^-1 significantly recorded higher plant height (133.2 cm), dry matter accumulation (163.9 g/ 0.5m^-1 row length), 1000 seed weight (34.4 g) and seeds per panicle^-1 (55.5/ 0.5m^-1 row length), seed yield (19.0 q ha^-1), straw yield (58.2 q ha^-1), net income (Rs. 27,021 ha^-1) and B:C ratio (2.1) over other nitrogen levels. Interaction between dates of sowing and nitrogen levels found non-significant.
