| Abstract | ||
| Summer squash (Cucurbita pepo L.), plants growing in different soils; at Abiss and New Burg El-Arab, were provided with three foliar materials: gibberellic acid (GA3), potassium sulphate (K2SO4), and their combination. Trials were conducted on the cultivar (Eskandrani) over two growing seasons. Treatments included both yield and plant vitality as well as insect pest infestation. The control of these insects used to be affected by spraying K2SO4 into leaves and it iS possible to combine both K2SO4 and GA3. to apply them together. Significant increments in early and total yield as well as in average fruit number were detected when the plants received K2SO4 alone or in a mixture with GA3 The foliar fertilizer K2SO4 significantly decreased the number of insects as compared with the control or GA3 treatments. | ||
