Improving Growth and Productivity of "Pear" Trees Using Some Natural Plants Extracts under North Sinai Conditions

This study was conducted during two successive seasons (2013 and 2014) at Baloza, North Sinai governorate, Egypt. The aim of this research is to study the effect of spraying pear trees with some natural plants extracts on yield, fruit quality and fire blight infection of Le-Conte cultivar. Seven treatments were done as follows: control treatment (spraying with water), garlic extract at (2 and 4 %), moringa extract at (2 and 4 %) and licorice extract at (2 and 4g/ L.). All treatments were sprayed once every month started form January until the harvest time (July).The obtained results revealed that all treatments were very effective in stimulating growth parameters (leaf area, chlorophyll, shoot length, shoot diameter, leaf mineral contents (nitrogen, phosphorus and potassium), yield, physical and chemical characteristics and fire blight infection of the fruits. Generally, licorice extract at (4g/ L.) increased the leaf area, chlorophyll, shoot length, shoot diameter in both seasons. In addition, moringa extract at (4%) improved leaf mineral content (N, P and K), yield/ tree, number of fruits /tree, fruit length, diameter, shape, weight, volume, T.S.S., total sugar, vitamin C, and decreased total acidity. On the other hand, garlic extract at (4%) gave the highest number and percentage of healthy fruits. Key word: garlic extract, licorice extract, moringa extract, Le-Conte "pear".
