EFFECT OF COMPOST AND SOME BIOSTIMULANT TREATMENTS ON GUAR PLANTS. A-VEGETATIVE GROWTH AND SEED YIELD

Abstract

This experiment was conducted at Abo Qurkas district, Minia Governorate during the two successive seasons of 2014 and 2015 to study the effect of compost and biostimulant treatments on growth and yield of guar plants. The data indicated that the application of compost (2.5, 5.0 and 7.5 ton/fed) significantly increased plant height, number of branches/plant, leaf area, fresh and dry weights of shoot/plant and per fed, root system traits, number of pods/plant, seed yield/plant and /fed comparing with control. The plants treated with Vit. E and plant extracts (garlic, moringa, aloe and green tea) each at two concentrations showed significant increases in all investigated parameters, in both seasons, as compared with the control. Among the ten treatments either garlic extract (300 ppm) or green tea extract at (150 ppm) gave the best results in this concern. The interaction was significant and the highest values in all measurements were obtained with compost (5 ton/fed) plus garlic extract (300 ppm) or green tea (150 ppm).
