| Abstract | ||||
| The aim of this study is to investigate the effect of foliar application of some organic substances (humic acid, fulvic acid and Algae extract) on vegetative growth, yield and fruit quality of “Costata” persimmon trees grown on clay loamy soil under surface irrigation. This study was conducted during 2011 and 2012 seasons at EL-Kanater, Horticultural Research Station, Kalubeia governorate, Egypt on "Costata" persimmon trees (Diospyros Kaki L.). The trees were 22 years old budded on "Lotus" rootstock and spaced at 4x5 m apart. Twenty one trees were sprayed four times {at full bloom, two weeks after fruit set, after one month of fruit set and at month before harvest} with humic acid at 1 or 2%, seaweed extract at 1 or 2% as well as fulvic acid at 1 or 2%. The results showed that, humic acid and algae extract gave better vegetative growth {leaf area, shoot length, leaf dry weight}, nutrition status {leaf content of N, P, K, Fe, Mn and Zn}, fruiting {fruit set and yield} as well as fruit characters {weight, size, dimensions, firmness}, {TSS%, acidity% and tannins%} as compared with control in two studied seasons. Also, higher concentration (2%) of all tested substances was more effective than low one. | ||||
