| Abstract | ||||
| This study was carried out in a private orchard, at Kafr El-Dwar, El-Behera Governorate, on "GrandNain" banana plants (Musa cavendishii Lamb.) during the 2006/2007 and 2007/2008 growing seasons. Twelve treatments of different Humic acid (HA), potassium (K) and Magneisum (Mg) HA:K:Mg ratios were applied. The results indicated that there were great effects on growth aspects, yield, physical and chemical properties and leaf mineral content with varying HA:K:Mg ratios. Since increasing HA:K:Mg rates from 0 to 10 gm/plant, K from 0 to 300 gm/plant and Mg from 0 to 150 gm/plant/year caused a remarkable promotion on all studied parameters. Leaf potassium and magnesium contents were increased with increasing the applied potassium and magnesium fertilizer rates. On the other hand, results did not show a constant trend due to different treatments in respect with phosphorus, but did not affect nitrogen content. The best treatment was obtained with using (HA:K:Mg) at rate of 10 gm/plant Humic acid, 300 gm potassium sulfate and 150 gm magnesium sulfate for all studied parameters. | ||||
