Field experiments were conducted in north-eastern hilly region (Chittagong Hill Tracts) of Ramgarh, Khagrachari Hill district to find out the response of Chilli cv. Balijhuri to different doses of N P K S and Zn under rainfed condition during the rabi seasons of 1996-97 and 1997-98. There were four levels each of N: 0,50,100 and 150 kg ha-1; four levels each of P2O5: 0, 60, 90 and 120 kg ha-1; K2O: 0, 60, 90 and 120 kg ha-1; three levels each of S: 0, 10 and 20 kg ha-1 and Zn :0, 2 and 4 kg ha-1. The effect of nitrogen was highly pronounced and that of P, K, S and Zn were beneficial on number of fruits per plant, fresh yield as well as dry yield. The fruits per plant, fresh yield and dry yield ton ha 1 were markedly increased with the increase of N P K S and Zn up to a certain (dose) level but had a hardly increase in yield of chilli (Capsicum annum Linn.) beyond this limit. The economic analysis recommended the treatment combination (T13) of 100:90:90:20:2 kg ha-1 of N: P2O5: K2O: S: Zn, respectively to be more suitable dose for fresh yield of chilli (20.03 t ha-1 in 1996-97; 21.11 ton ha-1 in 1997-98 and 20.57 t ha-1 in average of two years) and for getting the highest marginal rate of return (27552.88 %) with gross margin of TK. 5,08,106.98 ha-1.
