Effect of Foliar Application with Algae and Plant Extracts on Growth, Yield and Fruit Quality of Fruitful Mango Trees Cv. Fagri Kalan

El-Sharony TF, El-Gioushy SF and Amin OA

An experiment was conducted during two successive seasons 2013 and 2014 on mango trees cv. Fagri Kalan to study the effect of foliar spray with some extracts (algae at 2%, roselle at 10% and garlic at 5%) applied four times along each season (at full bloom, fruit set, one and two months later from fruit set) either each extract was sprayed solely or in different combinations each other. The influence was evaluated through the response of leaf N, P, K content, vegetative growth, yield and some fruit physical and chemical characteristics of mango cv. Fagri Kalan.
The obtained results showed that, spaying algae extract at 2% either alone or combined with one of two plants extracts (10% roselle and 5% garlic) particularly both plant extracts together surpassed in most cases other investigated spray treatments for improving most measurements of fruiting (fruit set, retention, yield and fruit quality), vegetative growth, and nutritional status, (leaf N, P and K content). Besides, roselle and garlic extracts spray had also a noticeable positive effect particularly on some fruit physical and chemical characteristics. Therefore, algae and investigated two plants extracts could be safely recommended as a natural biostimulants application for improving most desirable measurements of mango trees cv. Fagri Kalan grown under the same experimental condition.
