| Abstract | ||
| The experiment was conducted in lath house during 1/4 – 1/11 2010 in Neaimiyia Nursery –General Establishment of Horticulture and Forestry to study the effect of foliar application with humugreen, mixture of iron &zinc and interaction on some features of olive transplants –K18 and Sourani Variety. Humugreen (12% humic acid +3% fulvic acid ) Sprayed with 0,2,4 ml/ L. iron Sprayed in form of FeSO4.H2O 32.88% Fe together with Zinc in form of ZnSO4.7H2O 22.76%Zn in the following Concentration; 0, 2g/LFe&0.5g/LZn, 4g/LFe&1g/LZn,6g/LFe&1.5g/L Zn.Factorial experiment in Randomized Complete Block Design RCBD with three replicates .K18 exceed significantly in the average increase of main length stem , main stem diameter ,branches number ,leaves number ,while Sourani variety exceed in Leaf aera; and the two cultivars showed no difference in percentage of dry matter,N and P in leaves, while the higher percent of K detected in K18 Variety . Humugreen with 2 or 4 ml/ L caused significant effect in vegetative growth features where the average increase in 2 ml/ L were 39.9% in main stem length , 12.7% in branches number,10.3% in main stem diameter ,15.2% in number of leaves and 14.6% in leaf area with no significant different between 2 ml/ L and 4ml/L effects on all these features . Conentraction 2 g/L Fe &o.5g/ L Zn had significant effect on vegetative growth features , where average increase were30.1% in main stem length , 36.5% in branches number , 19.2% in main stem diameter , 28% in leave number and 18.3% in leaf area. While the other concentrations did not affect these features. Iron& zinc increased significantly the percentage of dry matter ,N,P and K In leaves,humugreen had similar effect except P show no response.The interaction between humugreen and Fe& Zn resulted a significant effect on all features except main stem length and percentage of nitrogen in leaves and the best results were found when using 2m/ L Humgreen and 2 g /L Fe&0.5 g/ L zn which resulted in improving vegetative growth and N,P,K content of leaves. | ||
