The effect of different doses of nitrogen and P2O5 on number of days required to flowering, plant height, number of branches, number of fruits per plant and seed yield of sweet pepper variety Yolo Wonder were studied at Indian Agricultural Research Institute Vegetable Research Station, Katrain, Kulu Valley during the year 1970 and 1971. The highest dose of nitrogen and P2O5 in combination, considerably reduced the number of days required to flowering. P2O5 alone induced early flowering. Minimum days required for flowering were observed with 187.5 kg of P2O5. Nitrogen doses increased the number of days required for flowering. The number of branches, number of fruits per plant and seed yield were significantly increased by higher doses of nitrogen and P2O5. The present study revealed that 250 kg/ha of nitrogen and P2O5 each induced early flowering i. e. within 44.60 and 36.93 days after planting in both the years. For maximising the seed yield in sweet pepper 250 kg/ha of nitrogen and P2O5 each is essential. This increase in yield was due to increase in number of fruits as well as early maturity.
