Abstract
This study was carried out during the two successive seasons of 2017 and 2018 on Sukkary mango treesbudded on Sukkaryrootstock,grown in sandy soil under drip irrigation system at Baloza district, North Sinai Governorate, Egypt. The aim of thisstudy was to investigatethe influence of usingchicken manure or chicken manure tea as organic fertilizers combined with/without some bio fertilizes; mycorrhizae(Glomus macrocarbium), Azotobacterchroococcum andBacillus circulanson improving yield and fruit quality characters of mango fruits (Sukari cv.). The chosen trees have been subjected to eleventreatments. The Chicken manure was added at 25 kg/tree in winter. While, chicken manure teawas added at 30 L/tree/season (divided into three equal doses; the first was added at growth start season and once every two months after the first)and also the bio fertilizes were applied three times parallel with the time of chicken manure tea treatments application. The obtained resultsindicated that chicken manure tea + mycorrhizae + A. chroococcum + B. circulanstreatment increased leaf area,chlorophyll and nitrogen contents, fruit set, weight and number, total yield and vitamin C content and decreased fruit drop. Furthermore,chicken manure tea + A. chroococcumtreatment   increasedleaf phosphorus and potassium content, fruit length, diameter, total soluble solids, total sugar and decreased fruit acidity. Application of bio fertilization treatments with chicken manuretea; chicken manure tea + mycorrhizae + A.chroococcum+ B. circulansshowed a positive effect on microbial determinations (total microbial counts, Azotobacterdensities and Bacillus counts in the rhizosphere region of mango tree). On the other hand, the colonization percentage of mycorrhizaeand number of spores/g soil attained higher values from using chicken manure fertilizers + mycorrhizae + A.chroococcum+ B. circulansas compared to control. Also, this treatment showed an effective role in improving soil fertility via increasing NPK content, decreasing EC and a slight significant difference in pH values.
