Abd-Elnafea, M.H.
This study was carried out in a private orchard, EI-Bostan district, Cairo Alexandria desert road, EI-Behaira Governorate, Egypt, on Williams banana plants (Musa cavendishii L.) during the two successive seasons (2007/2008 and 2008/2009). The experimental site represents newly reclaimed sandy soil irrigated by drip irrigation system. The study aimed to estimate the response of Williams banana to organic fertilizers at three doses i.e., low, medium, and high rates, versus mineral recommended dose. The three doses used alone or with effective microorganisms (EM). The obtained results cleared that organic fertilization with medium or high dose 1.0 fold (400 N + 250 P + 900 K unit/plant) or 1.5 fold (600 N + 375 P+ 1350 K unit/plant) of recommended mineral dose enhanced the most studied characters even EM added or not. Using organic fertilizers at 1.5 fold of recommended chemical dose improved vegetative properties, banana bunch weight and the most of fruit quality of banana plants. Moreover, continuous addition of organic fertilizers (accumulation effect) was superior to that fertilized once. Also, Williams banana fruit chemical properties were affected by organic fertilization treatments comparing with control. On the other hand, results of control plants (that received the recommended mineral dose) were better than plants received half dose of organic matter. Whereas, the lowest values of nitrate residues in fruits were gained from compost treatments. Moreover, the highest net profit/fed./year was the best value affected by 1.5 fold of organic fertilization treatment during the study especially with EM
