An experiment was conducted to observe the effect of exogenous application of GA3 on yield parameters of two popular soybean varieties viz., Co (Soy)3 and JS 335 when it was used as a gametocide to induce male sterility. In both the varieties pods per cluster was maximum at lower concentration of GA3. GA3 @ 700 ppm on combined sprays yielded least number of pods per plant in the test varieties. The trait number of seeds per plant in the variety JS 335 showed a positive trend with concentration of GA3 and the same trait showed a negative trend in the variety Co (Soy)3. GA3 combined sprays @ 700 ppm in JS 335 and 500 ppm in Co (Soy)3 resulted in higher seed yield per plant. GA3 at 500 ppm spray on 25 DAS has pronounced effect on 100 seed weight in JS 355. Significant differences have been observed in the GA3 treated plants when compared with the control plants.
