ABSTRACT

The performance of three varieties of Okra Abelmoschus esculentus L. Moench were observed based on their growth parameters on a coastal plain soil of Umudike, south eastern Nigeria. The three varieties of Okra were Clemson Spineless, V35, LD88 and were replicated and laid out in a randomized complete block design. Okra seeds were sown in the nursery by putting 5 seeds per pot. Before transplanting, the land was cleared, ploughed, harrowed, leveled andseedlings were transplanted at the 4th week and at the appearance of three leaves. The seedlings were spaced at 30 X 40cm. The growth parameters were recorded throughout and they included the plant height, number of leaves, number of flowers, germination count, germination percentage, and number of fruits. The results obtained were subjected to analysisusing ANOVA table. Significant differences were observed for all parameters measured. Variety LD88 recorded the highest when compared to other varieties. The three varieties (LD88, V35and Clemson spineless) also showed a very high level of significance in their germination count and germination percentage (P<0.01). The three varieties showed no significant difference in their leaf length, leaf width, number of flowers and number of fruits and it was observed that LD88 responded well in Umudike soil and performed better in terms of plant height, and emergence.
