.Abstract
A research work was undertaken in the University of Uyo Teaching and Research Farm, Main Campus, Uyo, from March to May during the 2023 cropping season to assess the effect of Organic Mulching and Neem Oil in the Control of Cucumber Beetles (spotted “Diabrotica undecimpunctata” and striped “Acalymma vitatum”) affecting the growth and yield of Cucumber (Cucumis sativum, Saira F1 variety). The experiment was laid out in Randomized Complete Block Design (RCBD). The experimental plot consisted of three (3) replicates with 2 treatments: organic mulch, organic Neem oil application and control. An early maturing variety of cucumber “Saira F1” was used as planting material sown in March which lasted till May. Data on insect pest population count, growth and yield parameters were studied and the data obtained were analyzed and subjected to analysis of variance using Fisher`s Least Significant Difference (LSD) at 5% probability level. The results from insect population count parameters revealed that Neem oil at 100ml application rate which recorded 10.50 and 6.00 was significantly effective in managing spotted and striped cucumber beetles respectively compared to organic mulch (3kg) which recorded 47.00 and 14.00 for spotted and striped cucumber beetles and control unit which had 61.00 and 42.00 for spotted and striped cucumber beetles respectively. Neem oil at 100ml application rate was also more effective in improving the growth and yield of cucumber plant compared to organic mulch. Hence, Farmers in Uyo, Akwa Ibom State should employ Neem oil in managing spotted and striped cucumber beetles in cucumber production as this is a promising botanical insecticide to check the activities of field cucumber beetles thereby bringing their destructive activities to a minimum and also improves yield.
