Studies on the growth, yield, and yield components of okra were conducted at Moor Plantation, Ibadan, Nigeria, in 1995 and. 1996. Increase in plant height, leaf stalk, internode length, pod length, and pod diameter were largely determined by cultivar characteristics. Fruiting peduncle, leaf nodes, and edible fruit yield were significantly different(P ¡Ü 0.05) among cultivars. Early flowering and longpods were indicators of low yield due to high negative correlation. However, late flowering, number of pods per plant, and length of fruiting peduncle were most highly positively correlated with yield, but highly negatively correlated with pod length. Of all the okra traits studied, number of capsules per plant was the ,most important determinant of yield. Days to first flowering was the most important character governing number of pods per plant which accounted for 52.7 per cent of yield variations. Edible fruit yield increased linearly until 14 weeks afterplanting and then declined. At 8 weeks after planting, internode length, leaf stalk length, and fruiting peduncle length increased as edible fruit yield increased. The period of most active growth of okra plant was 8 to 9 weeks after planting.
