This experiment was conducted for two consecutive summer seasons of 2016 and 2017 at Experimental Farm, Faculty of Agriculture, Zagazig University, Egypt to study the effect of silicon (Si) fertilization concentration (0.00, 300, 600 or 900 ppm), apical bud pinching (ABP) stages (ABP at the 4th node, the 6th node and 8th node and without ABP as a control) and their interaction on the growth, yield components and fruit quality of okra plants. The obtained results showed an increase in plant height, number of leaves and total dry weight/plant according to Si fertilization concentrations. That is, there were no significant differences between the control and silicon at 300 ppm concentration for number of branches/plant. On the other hand, the ABP at the 8th node significantly increased most of growth parameters of okra plants compared with the control and the other treatments under the study. Moreover, the increases in total green pods yield/feddan were about 47.20 and 43.24% for the interaction between silicon fertilization at 900 ppm concentration and ABP at the 6th node stage over the control in 1st and 2nd season, respectively. In addition the interaction between silicon fertilization concentrations and ABP at different stages had significant effects on traits of okra fruits quality viz. percentage of N, P, K and fibers as well as total carbohydrates in both seasons of the study.
