Impact of Biofertilizers as a Partial and Safe Substitute of Nitrogen Fertilizer on Some Growth, Photosynthetic Pigments and Yield Traits in Cotton Plants

Abstract: Attention has been focused on the use of organic and bio-fertilizers due to the pollution factor and high costs of mineral fertilizers.Therefore, two field experiments were conducted at the Experimental Farm of the Faculty of Agriculture at Fayoum in two successive growing seasons 2010 and 2011 to study the effect of bio-fertilizers (Microbin and Cerealin) with different levels of nitrogen.The treated cotton plants with inorganic N combined with microbin or cerealin bio-fertilizers improved all the studied growth traits of cotton, i.e. plant height, the number of leaves per plant, the total leaf area per plant and dry weight of leaves per plant as compared to the control treatment.The best results were observed when cotton plants were treated with 100 % inorganic N combined with microbin or cerealin for plant height trait in both seasons.Treatment of 80 % N + microbin or cerealin ranked as the first favorable treatments for enhancing cotton yield and leaf pigments in both seasons.From the obtained results, it could be concluded that the application of 80 % N + microbin or cerealin were favorable treatment for producing significantly higher yield with improved growth traits and seed cotton yield saving 20 % of N fertilizer.
