| Abstract:
The effects of varying levels of N and P on the yield and chemical composition of two high-yielding okra cultivars were investigated during two planting periods at Ibadan, Nigeria, in 1975. While the application of the first 56 kg N/ha significantly increased the yield of fresh fruit by 14.5% in the early planted crop and by 29.0% in the late season crop a further addition of 56 kg N/ha produced no significant additional yield. The increase in fruit yield was primarily due to an increase in the number of fruits per plant. Although the application of 12.4 and 24.9 kg P/ha had no significant influence on yield, the highest fruit yield was obtained when the highest levels of P and N were applied. Only 13.4 and 5.2% of applied N was recovered in fruits in the early and late season crops respectively. | |
