Experiment was laid out in Split Plot Design (SPD) with three replications and twelve treatment combination. Blackgram was sown on 13th July,2019 in a split plot design with crop geometry as main plot and variety in sub plot. There were six levels of crop geometry (cm) viz. S1-30×10 S2-30×5 S3-20×10 S4-20×5, S5-45×10 and S6-45×5 row to row and plant to plant and two level of varieties V1-Indira Urd-1 and V2-Pratap Urd-1. The crop was harvested on 5th October, 2019. Result indicated that the S4-20×5 cm at 20 DAS and at harvest was found effective in plant population and plant height, S5-45×10 cm at 20, 40 and 60 DAS was found effective in enhancing growth of branches and S1-30×10 at harvest was found effective in dry matter production of blackgram showed at par with S5-45×10 cm. The findings revealed that crop geometry (cm) 30×10 recorded significantly yield attributing characters, yield, gross return and net return. Variety Indira Urd-1 produced to significant higher growth parameters, yield attributing characters and net return and return per rupee invested as compared to Pratap Urd-1. The interaction between spacing and variety revealed that crop geometry 30×10 with variety Indira Urd-1 was produce significant higher seed yield as compared to other treatment combinations.
