A study was conducted at Research Farm of Division of Agronomy, Shalimar campus of SKUASTKashmir during rabi 2009-10 and 2010-11 to study the influence of dates of sowing, varieties and fertility levels on the economics of forage oat. The soil of the experimental field was silty clay loam, low in available nitrogen, medium in available phosphorus and potassium with neutral pH. The experiment was laid out in split plot design, having two dates of sowing (D1) 5 October and D2 (5 November), three varieties V1 (Sabzar), V2 (SKO-20) and V3 (SKO-108) and four fertility levels F1 (50+25+15 kg/ha, N, P2O5, K2O), F2 (100+50+25 kg/ha N, P2O5, K2O), F3 (150+175+35 kg/ha N, P2O5, K2O), F4 (200+100+45 kg/ha, N, P2O5, K2O). Treatments included combination of two dates of sowing and three varieties assigned to main plots and four fertility levels assigned to sub-plots with three replications. The results revealed that early date of sowing D1 (5 October) recorded highest net profit and benefit cost ratio of Rs. 80,312.66/ha and 3.38 for SKO-108 variety (V3) and F4 (200+100+45 kg/ha N, P2O5, K2O) fertility level (D1V3F4) treatment combination and lowest corresponding values with treatment combination 5 November. Date of sowing, variety Sabzar (V1) and F1 (50+25+15 kg/ha, N, P2O5, K2O) fertility level (D2V2F1) were Rs. 11,107.83/ha and 0.56 and F1 (50+25+15 kg/ha, N, P2O5, K2O) and fertility level (D2V2F1) were Rs. 11,107.83/ha and 0.56.
Key words: Sowing dates, cultivars, fertility levels, relative economics
