FOLIAR APPLICATION OF CHITOSAN IMPROVED GROWTH AND YIELD IN WINTER AND SUMMER TOMATO (Pages : 15 - 17)

M.T. ISLAM AND M. KHATOON

Chitosan stimulates immunity of plants and improves crop growth and yield. Two experiments were conducted to investigate the effect of foliar application of chitosan on growth and yield of winter and summer tomato. The experiment comprised four levels of chitosan concentrations viz., 0 (control), 50, 75 and 100 ppm. The chitosan was sprayed two times, 25 and 35 days after transplanting. Foliar application of chitosan increased plant height, number of branches, fruits plant-1, individual fruit weight and fruit yield in winter and summer tomato. The higher fruit yield was recorded in 75 ppm of chitosan in both winter and summer tomato. Therefore, foliar application of chitosan at 75 ppm may be used at early growth stage for getting maximum fruit yield of winter and summer tomato.Download
