| Abstract | ||
| This study investigated the effect of different Potassium with or without on vegetative growth and nutritional status of mango trees “Naomi” cv. the specific and interaction effects of two studied factors were evaluated. The vegetative growth (Shoot length and average leaf area) as well as nutritional status (Total chlorophyll and leaf (N, P, K, Ca, Mg as percentages" %") and (Fe, Zn and Mn part per million "ppm") were determined. The combination of foliar spraying with potassium (acetate, 3 cm/L) + soil drench application of Bio-K proved to be the most effective treatment for most of the parameters examined in this study. Treated Naomi mango trees with Bio-K only or potassium "K" (acetate) and interaction between them affected significantly all evaluated measurements. Also, it gave the highest values in all leaf mineral contents and total chlorophyll (SPAD) compared to the control. Results of leaf nutritional status characteristics and total chlorophyll (SPAD) took, to some extent, a similar trend to that of growth traits. On the contrary, the response trend took the other way around with P concentrations that showed a progressive increase with the gradual increase in untreated "control" treatments without or with Bio-K. | ||
