| Abstract | ||||
| Barhee date growers face a major obstacle that involves decreased fruit yield, productivity, and quality, especially among recently planted trees. In response, this experiment was developed to discover a potential resolution to this issue. productivity, and quality, especially among recently planted trees. Micro-nutrients like Boron and Zinc are crucial for various physiological functions in plants. So we designed this study to assess the effects of spraying female spathe with various boron sources, in combination with or without zinc sulfate “just before pollination and one month later” on the quantity furthermore quality production of Barhee dates through the two successive growing seasons. Spraying Boron sources, most of the recorded parameters significantly increased compared with control. Spraying boric acid at 4g/L recorded the highest values of fruit set (%), bunch weight (Kg), retained fruit percentage (%) and yield (Kg/ tree). While spraying nano boron at 200 mg/L increased the fruit quality. On the contrary, the control “water only” decreased all recorded parameters except seed weight (g) and seed percentage (%) were increased. Concerning spraying zinc sulfate, data revealed that spraying zinc sulfate significantly increased most parameters. | ||||
