Effects of Gibberellic Acid and Auxins on Growth and Yield on Peas
A field study was conducted to evaluate the response of growth hormones gibberellic acid (GA3) and auxins
(IAA – Indole-3-acetic acid) on pea crop (Pisum sativum). Application of different doses of growth hormones (GA3 and
IAA) was given at 4-5 leaf stage and the second application was given after 45 days of flower emergence and third
application after pod setting. We used GA3 of 5 ppm, 10 ppm and 20 ppm IAA of 10 ppm, 25ppm and 50 ppm. In which
GA3 of 20ppm produced best result for vegetative growth and GA3 of 10ppm produce best result for yield.
