- A field experiment was conducted during kharif 2016, to study the effect of date of sowing and fertilizer application on seed yield and quality of Sunnhemp genotypes (Crotalaria juncea L.) at Agricultural Research Station, Kalloli, Gokak taluk Belagavi district, University of Agricultural Sciences, Dharwad. The field experiment comprised of twenty four treatments with three replications in double split plot design. Among different dates of sowing, D3-First fortnight of August registered less days to flower initiation and 50 per cent flowering (36.22 and 55.50 days respectively) followed by second fortnight of July (D2-38.20 and 60.62 days respectively) and more number of days were shown in first fortnight of July (D1-40.12 and 65.62 days respectively). With respect to fertilizer levels, F1-25:50:25 NPK kg ha-1 recorded less number of days for flower initiation and 50 per cent flowering (36.58 and 57.07 days respectively) followed by F2 (38.01 and 59.91 days respectively) and F3 ( 39.95 and 64.76 days respectively). D3-first fortnight of August was recorded significantly higher seed yield per plot (1.04 kg) than D2-second fortnight of July (0.97 kg) and D1-first fortnight of July (0.90 kg). Fertilizer levels had a significant influence on seed yield per plot. Higher fertilizer level, F3 - 37.5 : 75 : 37.5 NPK kg ha-1 recorded significantly higher seed yield per plot (1.04 kg) than F2 - 31.25 : 62.5 : 31.25 (0.99 kg) and F1 – 25 : 50 : 25 NPK kg ha-1 (0.87 kg). Higher seed yield per hectare was recorded in D3-first fortnight of August (1,798 kg) as compared to the D2 and D1 (1,686 and 1,569 kg respectively). Among the fertilizer level, F3 - 37.5 : 75 : 37.5 NPK kg ha-1 recorded significantly higher seed yield per hectare (1,808 kg) than F2 - 31.25 : 62.5 : 31.25 NPK kg ha-1 and F1 – 25 : 50 : 25 NPK kg ha-1 (1,727 and 1,517 kg respectively)
