Effect of Microbial Biofertilization on Reducing Chemical Fertilizers, Vegetative Growth, Nutritional Status, Yield and Fruit Quality of Apple [electronic resource]. تأثير بعض المخصبات الميكروبية على خفض استخدام الاسمدة المعدنية والنمو الخضرى والحالة الغذائية والمحصول وجودة ثمار التفاح. P. 121-129. Includes references. Microbial inoculum contained main organisms (beat-based): Azotobacter spp. and Bacillus megatherium which found in ‘Biogein’, ‘Rhizobacterein’, ‘Phosphorein’ and arbuscular mycorrhizal (AM) fungi were used to reduce the recommended dose of nitrogenous and phosphoric fertilizers of "Anna" apple trees. The treated trees were seven years old budded on MM. 106 rootstock grown on sandy soil at Elbostan district under drip fertigation system during two successive seasons (2003 and 2004) to investigate the influence of the microbial biofertilization on tree growth, yield and fruit quality. The treatments were 100% of recommended mineral fertilizers dose/tree without microbial biofertilization (control) and 100% (F1), 50%(F2) , 25% (F3) of recommended mineral fertilizers dose plus microbial fertilizers. shoot length, leaf area and leaf dry weight of treated trees with microbial biofertilization were significantly increased. while, specific leaf weight (SLW) was not statistically affected with any treatment. also, chlorophyll a, chlorophyll b and total chlorophyll content of the leaf recorded significant increases compared with uninoculated control trees.
