Effect of Cultivars on Growth and Yield of Okra (Abelomoschus esculantus L. Moench) under Different Conditions in South East Kordofan, Sudan

Abstract

Okra (Abelmoschus esculentus L. Moench) is a vital vegetable crop cultivated extensively in Sudan. It is esteemed for its rich nutritional value, offering significant amounts of vitamins A, C, thiamine, riboflavin, niacin, calcium, phosphorus, and potassium, contributing to dietary and economic value. A field experiment was conducted in South Kordofan State in Alabassia Locality, Sudan, during two seasons (autumn and winter) 2022/2023 in randomized complete block design (RCBD) with four replicates. The aim of Study to investigate the effect of varieties on growth and yield. Five varieties were used in this study, four improved varieties: Green grad, Pusaswani (Kararri), foriegn spiny, Kararri spineless with an old local traditional variety widely used by farmers, Umkirshat. The treatment were arranged. Character studies included growth attributes: plant height (cm), number of leaves per plant, stem diameter (cm), number of branches per plant. Yield parameters included: number of pods per plant and yield (ton ha-1). The results revealed that the varieties had a significant differences (p = 0.05) in plant height, number of pods per plant and fruit yield (ton ha=1) for the two seasons. Results showed that the highest productivity attained by the varieties Green Gard and Kararri spiny in the summer (autumn) season about the 2.87 and 2.47 ton ha-1 respectively. In winter season the highest fresh fruit yield (0.407 ton ha-1) attained by the variety Green Gard. From these result the autumn season was favorable for growing the okra in Alabassia Tagali locality, Sudan. The variety Green Gard of recommended as prospected cultivar to be used by okra farmers of North Kordofan state to attained highest pods yield.
