Abstract
In the field trial, treatments comprising of different concentration of GA3, 0, 10, 25 ad 50 ppm, with two methods of application i.e. presowing seed treatment and foliar spray at early seedling, primordial initiation and spikelet differentiation stages were studied. The treatments were arranged in randomized block design having replications. Characterization and quantification of certain seed yield components shown increased seed yield characteristics as a matter of applying gibberellic acid (GA3).
Keywords: Seed yield components, Sorghum bicolor.
