| Abstract | ||
| A field experiment was carried out during 2020 and 2021 seasons on 7 years old Murcott mandarin trees grown in sandy soil under drip irrigation system from well at private orchard at El farafra road , Alwadi aljadid Governorate Egypt. The aim of this study is to investigate the effect of four levels of algae foliar spray Algae 90% Amphora Coffeaeformis (0.0, 0.5, 1 and 1.5 g/litter) and three levels of chelate Zinc foliar spray at (0.0,0.4g and 0.8g/litter) on vegetative growth parameters, yield and fruit quality of Murcott mandarin trees. Obtained results showed that the combination of chelate zinc and Algae 90% Amphora Coffeaeformis enhanced vegetative growth parameters, yield, and fruit quality traits when compared with untreated trees (water spray). As a conclusion, the combination between algae Amphora Coffeaeformis (AC) at 1g spray and chelate zinc(CZ) at 0.8g recorded the best results of vegetative growth ,fruit set percentage , number of fruits /tree , yield / tree , yield / feddan , fruit physical properties , fruit chemical properties and leaf N%,P%,K% content. | ||
