Homobrassinolide application as seed treatment (0.01 and 0, 05 ppm) resulted in increased germination, α amylase activity and total soluble protein in 48h old seedlings and shoot length in 96 h old seedlings both with and without PEG-6000 induced moisture-stress. The data indicate that homobrassinolide may affect enzyme activity as well as protein synthesis resulting in higher seedling growth. In the field grown crop, homobrassinolide treatment under irrigated and rainfed condition resulted in singificant increase in seed yield. The increase in seed yield was associated with increase in ear number per plant, grain number per ear, 1000 grains weight and harvest index.
