“…They recommend that total fruit production, first fruit-producing node, first flowering node, number of fruits per plant and stem diameter at the base should be given more attention when selecting for higher yield and high dry matter in okra. However, the view of this study is in contrast with earlier view that early flowering is detrimental to overall productivity of okra as the source to sink ratio will be potentially limited for effective photosynthesis (Aboagye et al, 1994). Another opinion is that wide range of flowering periods among the accessions implies varying maturity periods even on the same plant making it difficult for uniform or mechanical harvesting (Ahiakpa et al, 2013).…”

In a two-year study, participatory variety selection (PVS) was employed to evaluate the performance of 19 okra (Abelmoschus esculentus L.) c. v. Moench genotypes in a semi-arid agro-ecology in northern Ghana. The PVS sessions were organized at 65, 80 and 95 days after planting for 272 farmers to select the most preferred genotypes base on plant growth, maturity period and yield components. Results of this study indicate high significant differences among the genotypes (P< 0.0001) for most essential agronomic yield traits evaluated. Five most recurring preference traits were high fruit yield, early maturing, multiple harvest frequency, drying quality and long tender-life. Glabrous leaf, stem and fruit were important to farmers because most of the production operations are still being manually done. Genotypes with high potential included: NOKH 1004 (9.55 ton\ha), FV-Unn-manna (5.85 ton\ha), NOHK 1003 (5.17 ton\ha), NOKH 1002 (2.83 ton\ha), FV-Kpazeya (2.83 ton\ha), TZ-SMN-86 (2.30 ton\ha), AAK (2.11 ton\ha), NB-55-Srivan (1.98 ton\ha), Sasilon (1.70 ton\ha), FV-Unn (2.20 ton\ha) and Ex-Makutopora (1.27 ton\ha). Genotypes Sasilon, NOKH-1004, NB-55-Srivan and NOKH-1003 recorded the highest ranking among farmers during the PVS. High yielding and early maturing genotypes which are amendable to drying may show wide adoption rate due to the premium on dehydrated okra. These genotypes can be suggested as candidates for inspection by the National Variety Release and Technical Committee for release to farmers to increase access to improved okra varieties.

“…It has been demonstrated that on a general basis, early flowering is detrimental for overall productivity in okra as the source to sink ratio will be potentially limited for effective photosynthesis [24]. Differences in flowering periods among the varieties in the current study imply that their maturity periods vary.…”

Okra (Abelmoschus esculentus L. Moench) is an important all-season food crop widely grown throughout the tropical and semi-temperate regions of the world, for its tender green pods and leaves. Unfortunately, the crop rarely reaches its yield potential in most of these areas, primarily due to the use of unimproved cultivars and limited utilization of fertilizers and irrigation inputs. In addition, investments in breeding programmes that are aimed at enhancing its yield in the field are very limited. In the current study, therefore, some agronomic traits and yield components of four cultivars of okra (NHAe-47-4, V35, LD88 and a local variety), were compared in a field plot to aid in the development of selection strategies that could be used for okra improvement. The experiment was laid out in a completely randomized design with each accession, which served as the main factor, replicated five times and grown to maturity. Data collected from the four varieties included number of days to seedling emergence, number of days to flowering, plant height at flowering, number of leaves at flowering, mean number of pods per plant, pod length, mean number of seeds per pod, and mean weight of one hundred seeds, which were individually subjected to analysis of variance (ANOVA) test. The results demonstrated that the okra varieties differed significantly (p<0.05) in number of days to flowering (71.75-112 days), plant height at flowering (49.75-128 cm), number of leaves at flowering (7.50-19.33), pod length (3.23-6.83 cm) and one hundred seed weight (3.87-4.42g). There were, however, no significant (p>0.05) differences between the cultivars in terms of certain yield characters including average number of pods and average number of seeds per pod per plant. Taken together, the findings from this study will certainly be useful to okra breeders for appropriate selection strategies in cultivar improvement programmes.

“…Aboagye et al (1994) found negative correlations between leaf area index and net assimilation rate, suggesting that mutual shading decreased crop production in peanut. One of the prohibitive factors for increasing harvest index in peanut may be excessive dry -matter distribution to stem (Maeda, 1993).…”
