Method: A research study was set up in split plot design including three irrigation conditions as a main factor namely 1) Irrigation at sowing and seedling stage (I₀), 2) Irrigation condition at sowing, seedling stage and 50% flowering stage (I₁), 3) Irrigation at sowing seedling stage, 50% flowering stage and 50% pod development stage (I₂) and 20 soybean genotypes as a sub factor. At harvest morphological parameters such as plant height and number of branches plant^-1 were documented in addition to the drought tolerance efficiency on basis of yield.

Result: The results revealed significant variations between genotypes under Irrigation at sowing and seedling stage (I₀) and Irrigation at sowing seedling stage, 50% flowering stage and 50% pod development stage (I₂). Plant height and number of branches plant^-1 showed a significant drop in irrigation at sowing and seedling stage (I₀) i.e. moisture stress condition. The genotype KDS-992 was found moisture stress tolerance genotype with higher plant height and number of branches plant^-1. Whereas KDS-1271 was identified as a moisture stress susceptible genotype.
