| dc.description.abstract | Field experiment was conducted at University of Agricultural Sciences, Dharwad in Northern Transition Zone of Karnataka to study the effect of oat genotypes to seed rate and nitrogen levels on forage yield and quality under irrigation during rabi 2010-11. The experiment was laid out in randomized complete block design involving two genotypes (JHO-822 and OS-6), three seed rates (75, 100 and 125 kg ha-1) and three nitrogen levels (90,120 and 150 kg ha-1). FYM @ 7.5 t ha-1 and nitrogen as per treatments along with 60:40 kg P2O5 and K2O ha-1 was applied and crop was harvested twice for green forage at 50 per cent flowering stage. Forage quality parameters were analysed on whole plant dry matter basis. The oat genotype JHO-822 produced significantly higher total green forage (57.21 t ha-1) and total dry matter (10.87 t ha-1) compared to the genotype OS-6 (55.30 t ha-1 and 10.51 t ha-1, respectively). The seed rate of 125 kg ha-1 produced significantly higher green forage (37.20 t ha-1 during first harvest, 25.09 t ha-1 during second harvest and 62.29 t ha-1 total) compared to 75 and 100 kg ha-1 seed rate. The nitrogen level of 150 kg ha-1 produced significantly higher green forage (38.44 t ha-1 during first harvest, 24.14 t ha-1 during second harvest and 62.58 t ha-1 for total) compared to 90 and 120 kg ha-1 nitrogen. Significantly higher total green forage yield (73.83 t ha-1), total dry matter yield (14.03 t ha-1) with superior forage quality , net returns (Rs. 28774 ha-1) and benefit cost ratio (2.85) can be obtained with genotype JHO-822 with 125 kg ha-1 seed rate at 150 kg ha-1 nitrogen. | en_US |
