EFFECT OF FOLIAR APPLICATION OF CHITOSAN ON GROWTH AND YIELD IN TOMATO, MUNGBEAN, MAIZE AND RICE (Pages : 7 - 17)

Pot and field experiments were conducted under sub-tropical condition (24075´ N and 90050´ E) to investigate the effect of foliar application of chitosan on morphological, growth and reproductive characters and its consequence on fruit or grain yield of summer and winter tomato, summer mungbean, maize and, Aman and Boro rice. Chitosan was sprayed @ 25, 50, 75 and 100 ppm for tomato and mungbean, 50, 75, 100 and 125 ppm for maize and 25, 50 and 75 ppm for rice. Chitosan was sprayed two times on tomato and mungbean at vegetative and flowering start phases. Chitosan was sprayed three times on maize and rice at vegetative and flowering stages. Foliar application of chitosan at vegetative stage enhanced plant growth and development which resulted increased in total dry mass production of tomato, mungbean, maize and rice. However, among the studied crops, foliar application of chitosan on rice had little effect on growth and development. Application of chitosan increased the prime yield component, number of fruits or pods or grain plant-1 and resulting increased fruit or grain yield of summer and winter tomato, summer mungbean, maize and rice. Among the concentrations, 75, 50, 100 and 50 ppm respectively for tomato, mungbean, maize and rice had superiority for yield components and seed or fruit yield over other concentrations. Therefore, application of chitosan @ 75, 50, 100 and 50 ppm, respectively for tomato, mungbean, maize and rice may be recommended for increasing yield. Download
