Response of Sweet Pepper Plants to some Organic and Bio-fertilizers and its Effect on Fruit Yield and Quality

It can by using organic and bio-fertilizer minimize vegetables plants requirements from inorganic synthetic fertilizers which are potentially more detrimental to the environment. The objective of this work was to study the response of sweet pepper plants cv. California Wonder to some micro-organisms and organic fertilizer by soil inoculation with different rats of compost tea (10 or 20 L/fed.) alone or combined with azolla (10 or 20 L/fed.) or yeast (Saccharomyces cerevisiae) (10 or 20 L/fed) plus 75% from the recommended mineral fertilization (NPK) of sweet pepper plants for all treatments comparing with full dose of NPK (100%) as control treatment. Field experiment was carried out during two successive summer seasons (2013 and 2014) in the experiment farm of Kaha, Qalubia Governorate, Egypt. The obtained results of this study indicate that, soil inoculation with combination between compost tea, azolla and yeast (Saccharomyces cerevisiae) at high rat, i. e. 20 L/fed. plus 75% from the recommended mineral fertilization (NPK) of sweet pepper plants gave the significant highest increase in microbilogical parameters (total count of bacteria and yeast, dehydrogenase and nitrogenase activity), vegetative growth parameters (plant length, number of leaves and branches per plant, leaf area as well as, fresh and dry weight per plant) and chemical composition N, P and K% of sweet pepper plants and leaf chlorophyll content).This treatment led to significant increase in yield and its components (fruit length and diameter, fruit fresh weight and dry matter percent in fruit as well as early and total yield) with highest quality for fruit (N, P, K% and Vitamin C) in both season.
