Abstract
This experiment was aimed to test the effect of apical pinching, humic acid and plastic mulch on different growth parameters of okra. The results showed that pinching 2 was superior over the pinching 1 in fruit number and total yield in 2016 and 2017 seasons. Application of humic acid significantly increased all traits in two study seasons. It was also noticed that plastic mulch significantly increased all studied traits in both seasons. The interaction between pinching and humic acid were characterized by the upper values of most detected traits. The interaction between pinching 2 and clear mulch caused an increase in most characteristics in both of the study seasons. The combination treatment between humic acid at 20ml.L-1and clear mulch had significant effect in most parameters, while the combination between 40ml.L-1 and clear mulch gave the highest rate of nitrogen %, phosphorus % and potassium % in 2017 only. The combination among pinching, humic acid and plastic mulch significantly enhanced all studied traits in both the season (2016 and 2017).
