Response of grand naine banana plants grown under different soil moisture levels to antitranspirants application

Abstract

The effect of two soil moisture potential 40 and 60% of the available water depletion with spraying three types of antitranspirants at 2% each on water consumptive, water use efficiency, growth, nutritional status, yield and fruit quality were studied . Results indicated that, varying1 soil moisture contents had no effect on leaf nutrient content, yield and fruit quality. However, using 60% of the available water depletion effectively reduced water consumption use and enhanced water use efficiency rather than using 40%. Most of the growth, yield and quality parameters as well as water use efficiency were improved significantly influenced by spraying antitranspirants which were responsible for reducing water consumptive use. Only, the number of green leaves they had no effect comparing with the check treatments. The effectiveness clearly showed with using calcium carbonate, Green miracle and kaolin in descending order in the previously studies. Under these conditions ,using calcium carbonate weekly at 2 and 60% of the available water depletion that improved productivity as well as saving irrigation water amounts of Grand Naine banana plants. © 2013 Asian Network for Scientific Information.
