| Abstract:
The responses of two high-yielding okra cultivars to different population densities were investigated early and late in the cropping season of 1975 at Ibadan. Compared with total fresh fruit recorded at the lowest population density of 18,000 plants/ha, yield was increased by 67% at 108,000 plants/ha when sown early in the season and by 136% late in the season. The magnitude of yield increase as a result of increases in plant population was higher in the early maturing CV. "Pusa Sawani" than in the medium maturing CV. "Ibk-2". The number and weight of fruits per plant as well as number of vegetative branches per plant decreased significantly with increase in population density. Increasing population density by establishing two plants per stand during early planting was desirable for "Ibk-2" but not for "Pusa Sawani". However, with late planting in the season two plants per stand was found to increase yield for the two cultivars over the single plant per stand. | |
