Abstract
The use of chemical fertilizers to improve soil fertility, and hence, crop yield, have been reported to have adverse effects on agricultural products, man and his environment, hence, this research looked into the growth and yield response of foliar application with Moringa oleifera leaf extract on Okro. Different concentrations of Moringa leaf extracts at the rate of 5ml, 15ml and 25ml was assessed on the growth and yield of Okro using topsoil as the growing medium. The experiment was laid out in a randomized complete block design with three replicates. Growth and yield parameters were collected on plant height, number of leaves per plant, number of fruits per plant, and length of fruit per plant. Parameters measured were subjected to Analysis of Variance (ANOVA) for Completely Randomized Design (CRD) and means were separated using Duncan’s Multiple Range Test (DMRT) at 5% probability level. The results showed that the treatment with 25ml concentration has a more significant effect than others on Okro. Therefore, treatment with 25ml performed better than the other two treatments in the study area. Hence, this study recommends the foliar application of Moringa extract to farmers for improved yield and production of Okro.
Highlights
In Nicaragua, cattle feed consisting of 40–50% moringa leaves is mixed with molasses, sugarcane, and grass
Adverse effects resulting from high rates of moringa in feed are due to ex
The strong tradition of medical uses of moringa combined with recent scientific work supporting these traditions has resulted in increased marketing of supplements and socalled “superfoods” based on moringa
Summary
Almost all parts of the moringa tree are used for food, oil, fiber, and/or medicine. In the Pacific, the most important products are pods and leaves. Young pods are consumed as a vegetable. Very young pods are fiberless, and can be cooked like string beans. Because the weight is low on very young pods, most commercial production involves larger, more fibrous pods that are used in soups, stews, and curries. The nutritious leaves are eaten in many dishes including soups, stews, and stir fries. Sauteed young leaves and flowers are eaten. The demand for home consumption of pods and leaves can generally be met by one or two backyard trees
