An experiment was conducted for 3 pre-rabi season during 1989-92 to find out the effect of sowing date and nitrogen level on yield of niger (Guizotia abyssinica Cass.). Sowing on 15 August gave the highest yield. The crop respondedfavourably up to 30 kg Nlha with the highest net profit (Rs 3,735lha) and returnlrupee invest- ment (Rs 17). Interaction effect between sowing dates and N on niger was signifi- cant.References
niger sown on 15 August recorded the high- est seed yield at all the levels of N (Table 3). Application of 30 kg Nha recorded the maxi- mum seed yield on all the dates of sowing. Nitrogen-use efficiency was higher at 15 kg Nha than at 30 kg Nha which explained the maximum use of N even at lower level over control at optimum time of sowing (Table 2).
Application of 30 kg Nha recorded the highest additional seed yield (Table 1) and profit than the control, with a return of Rs 171 rupee spent on N (Table 2). In 15 August sowing an additional seed yield of 4.5 qha (Table 3) and profit of Rs4,5 12with a return of Rs231 rupee invested was obtained by the application of N over the control.
