- Abstract
A field experiment was conducted at College of Agriculture, Hassan during kharif 2018 to study the growth, yield and quality parameters of fodder oats (Avena sativa L.) under varied dates of sowing and nitrogen application. The experiment was conducted on red sandy loam soil and the experiment was laid out in a factorial RCBD with 10 treatment combinations, which consisted of five different dates of sowing and two nitrogen levels replicated thrice. The results revealed that sowing during first fortnight of June recorded significantly higher plant height (133.42 cm), number of tillers (93.80) 0.5 m-1 row length, leaf to stem ratio (0.76), leaf area (3,766 cm2 0.5 m-1 row length), dry matter accumulation (97.73 g 0.5 m-1 row length) and SPAD readings (29.83), green fodder yield (28.88 t ha-1), dry fodder yield (5.79 t ha-1) crude protein (6.39%), B:C ratio (2.32) as compared to other dates of sowing. Application of 125 kg N ha-1 recorded significantly higher leaf to stem ratio (0.57), SPAD readings (25.46), leaf area (3,151 cm2 0.5 m-1 row length) green fodder yield (23.57 t ha-1), uptake of nitrogen, phosphorous and potassium (96.80 kg ha-1, 16.86 kg ha-1 and 82.11 kg ha-1, respectively) gross returns (Rs.47156/- ha-1) and net returns (Rs.22279/- ha-1) as compared to 100 kg N ha-1.
