Leaf gas exchange, reproductive development, physiological and nutritional changes of peanut as influenced by boron

Abstract

Boron application at proper concentration is necessary to enhance the leaf gas exchange, physiological growth, reproductive development and nutritional improvement of crops. Therefore, an experiment was conducted to study the effects of boron to evaluate the effect on the leaf gas exchange, reproductive development, physiological and nutritional changes of peanut. Treatments comprised six levels of boron (B), viz., B1 (0 ppm), B2 (0.5 ppm), B3 (1 ppm), B4 (2 ppm), B5 (4 ppm) and B6 (8 ppm). Results revealed that the vegetative growth, physiological growth parameters, leaf gas exchange, reproductive characters, peg strength, shelling (%) and nutritional elements were increased for boron application. Some vegetative, physiological and reproductive traits are positively correlated with each other. Thus, this finding showed that boron can be used to culture peanut as it provides high yield and nutritional properties.
