Abstract
Two field experiments were carried out at two successive seasons of 2018 and 2019 to study the direct effect of biochar, compost and bio-fertilizer (N fixing bacteria as Rhizobium leguminosarum for pea or azotobacter for sweet pepper and phosphorus solubilizing microorganisms as phosphoren) under three rates from the recommended mineral fertilizer and their interaction on pea plants (Pisum sativium) cv. Entsar 1 as first experiment and the residual influence of the previous fertilizers on sweet pepper plants (Capsicum annuum L.) cv. California wonder which was planted as second experiment crop. The results according to pea plants gave the best growth attributes, yield and its components were registered by the treatment of biochar with compost and fertilizer. Regarding to the residual influence of biochar, compost and bio-fertilizer led to high values on growth, yield and its characters of sweet pepper fruits in both growing seasons.
