Abstract

An experiment in cotton MCU.7 was conducted to study the effect of anti transpirants like Kaolin, PMA, Cowdung slurry, Gurel, Liquid paraffin, Sandovit, Power Oil and Lime wash on the Kapas yield and its components, for three years from summer 1986 to 1988. The treatment differences for kapas yield, number of symposia/plant and number of bolls/plant were significant. Consistently higher kapas yield was obtained in the plots sprayed with Kaolin 3%. The crop received Liquid paraffin 1%, Cowdung slurry 5% and Gruel 1% sprays were also recorded considerably higher kapas yield. The ancillary data revealed that the higher kapas yield would have been achieved through number of symposia and number of bolls contributed by the physiological factors like high RWC and low stomatal count.
