Abstract:Two field experiments were conducted in two consecutive years under sub-tropical condition (24°75’ N and 90°50’ E) during the period from December to April, 2010-2011 and 2011-2012, to investigate the effect of foliar application of chitosan (a growth promoter), on morphological, growth, yield attributes and seed yield of maize plants. The experiment comprised five levels of chitosan concentrations viz., 0 (control), 50, 75, 100 and 125 ppm. The chitosan was sprayed three times of 35, 50 and 65 days after sowing. Results revealed that foliar application of chitosan at early growth stages improved the morphological (plant height, leaf number plant-1, leaf length and breadth, leaf area plant-1), physiological (total dry mass plant-1, absolute growth rate and harvest index) parameters and yield components thereby increased seed yield of maize. The highest seed yield was recorded in 100 and 125 ppm of chitosan in maize. Therefore, foliar application of chitosan at 100 ppm may be used at early growth stage for getting maximum seed yield in maize.
