Abstract
Abstract ‘Everglades 71’, ‘Guatemala 4’, ‘Guatemala 45,’ and ‘SH/15R’ kenaf ( Hibiscus cannabinus L.) were planted at four 2‐week intervals in 1970–1972, to determine differential response to planting date. There was no planting date ✕ cultivar interaction for yield or plant height in any year, nor for stem diameter in 1970. In 1971, yield tended to decrease with successively later planting dates and was 66% lower at the last as compared with the first planting, but in 1970 and 1972 planting date did not affect yield. Stem diameter and plant height also were reduced by later planting in 1971. Everglades 71 in 1971 and SH/15R in 1972 produced higher yields than the other cultivars. Basal stem diameter of SH/15R was greater than that of other cultivars in 2 of 3 years. Generally, cultivars did not differ in plant height in any year. Results indicate that there was no advantage of one cultivar or planting date over the others tested.
