Abstract
Two field experiments were conducted during the winter season 2014-2015 and 2015 – 2016 at Experimental Station Farm, Horticultural Research Station, Behera Governorate, Egypt, to study the influence of two bentonite types (black and brown) and rates of their application (0, 5, 10, 15 ton/fed) on some vegetative growth characters, yield and its components of potato plants (Sponta c.v.) and some physical and chemical characteristics of sandy soil. The results indicated that vegetative growth characters (plant height, branch number/ plants, fresh and dry weight/plant) were significantly increased by addition of black bentonite as compared to brown one. Also yield and yield component (tuber yield/plant, number of tuber/plant, weight of one tuber and tuber yield/fed) were higher due to application of black bentonite compared to brown one. Three application rates (0, 5, 10, 15 ton/fed) significantly increased all vegetative character, yield and its component. The highest increase were obtained for application of 15 ton/fed bentonite. The interaction effect between two bentonite types was significant. The highest increases in vegetative growth, yield and its components were obtained for application of 15 ton/fed black bentonite. There were no significant difference between two bentonite types on chemical contents of foliage contents (N, P and K) and tuber contents (starch, protein N, P, and K). Application rates (5, 10 and 15) all significantly increased chemical, N, P and K contents of foliage and tuber. The highest increase were obtained by application of 15 ton/fed bentonite. The interaction between two bentonite types and their rates of application reflected positive effect in all chemical contents of foliage and tuber. The highest increased was obtained by application of 15 ton/fed black tafla. Application of black bentonite had significant effect on soil E.C., CEC, organic matter, water holding capacity as compared to brown bentonite. Rates of (0, 5, 10, 15 ton/fed) significantly increased all studied chemical and physical soil characters. The interaction between two bentonite types and its rates of application reflected positive effects on all studied characters of soil. The highest effect was obtained due to application of 15 ton/fed black bentonite.
