Abstract
This study was conducted in the hort. Station of Mahaweel – Hort. & For. Company during year 2005/2006 to find out the impact of cultivars and foliar nutrition with PRO.SOL on the vegetative growth characters of apricot seedlings Kaisy and Zaghenia budded on apricot seedling rootstock and on their leaves NPK content in leaf .Results indicated that the cultivars showed an significant influence on most studied characters. Kaisy cultivar, however gave the highest graft union percentage 84.44% , leaf area 17.08 cm2 , shoot diameter 9.68 cm , rootstock diameter 12.95 mm , vegetative and root system dry weight percentage 57.62 , 55.29 % respectively . No significant differences were observed between the cultivars studied regardling leaf P and K content , Nitrogen content were significantly domenat with Zaghenia cultivar . Monthly interval spray with the nutrient solution PRO.SOL had shown significant effects on leaf mineral content and all vegetative characterestics studied comparing with non treated . Interaction between Kaisy cultivar and monthly spray recorded a significant increase of leaf area , scion stem diameter , stock diameter and vegetative and root system dry weight percentage 21.76 cm2 , 11.12 mm , 15.50 mm , 59.03 % and 59.94 % respectively . While Zaghenia with monthly spray interaction showed highest NPK content 2.57 % , 0.29 % and 1.36 % respectively .
