Abstract
This investigation was carried out during two successive seasons of 2014 and 2015, at Abo Qurkas (Kafr Leps village) - Minia Governorate aiming to study the effect of organic fertilization (compost at 2.5, 5.0 and 7.5 ton/fed. as main plot (A) and vit. E (10 and 20 ppm), as well as, some plant extracts (garlic, moringa, aloe and green tea, each at 150 and 300 ppm) treatments as sub-plot (B) and their interaction (A×B) on vegetative growth, yield and yield components, guaran content and some chemical constituents of guar (Cyamopsis tetragonoloba, Taub.) plants.
All treatments of organic fertilization significantly increased plant growth parameters, yield and guaran production, as well as, chemical constituents. In most cases, vit. E and plant extracts treatments increased vegetative growth traits, yield and guaran production, as well as, NPK elements % and photosynthetic pigments. Fertilizing guar plants with compost (5.0 ton/fed.) in combination with garlic extract (300 ppm) followed by green tea extract (150 ppm) and vit. E (20 ppm) gave the best results.
Under the same conditions of this investigation, it could be recommended that fertilizing guar plants with compost at 5.0 ton/fed. and spraying plants with garlic extract (300 ppm) or green tea extract (150 ppm) or vit. E (at 20 ppm) to improve the plant growth, yield and guaran production.
