Effect of variety and spacing on growth and yield of Blackgram (Vigna mungo L.) under Vertisol of Chhattisgarh

Abstract

The present investigation entitled “Effect of variety and spacing on growth and yield of Black gram (Vigna mungo L.) under Vertisol of Chhattishgarh’’ was carried out at Instructional cum Research Farm, DKS College of Agriculture and Research Station, Bhatapara during Kharif season of 2019-20, with the objective to study the effect of different spacing and variety on growth and yield of blackgram. The soil of the experimental field was medium texture with low, medium and high in N, P and K, respectively. The climate of the region is sub-humid to semi-arid. 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.
