Abstract: A field experiment was conducted at Research cum Instructional Farm, IGKV, Raipur, during rainy season of 2018. Optimum plant population is pre requisite obtain higher seed production and productivity of soybean. These was obtained on varieties and plant geometry (cm). Soybean variety RSC 1046 was recorded significant higher plant population, Plant height, number of branches plant^-1 dry matter accumulation plant^-1, Leaf area index plant^-1 and seed yield. Crop geometry was recorded significant maximum plant population and plant height in 45×5, number of branches plant^-1 and dry matter accumulation plant^-1 in 45×10 leaf area index plant^-1 in 45×5 and seed yield in 45×10. Interaction effect in seed yield was recorded between variety and crop geometry (cm). RSC 1046 and 45×10 show significant higher seed yield. Relationship between plant population and seed yield (kg ha^-1) was linear with performance maximum in variety RSC 1046 and crop geometry (cm) 45×10. That results shows optimum plant population due to variety and crop geometry produce higher pre harvest parameters and yield soybean planted in ridge and furrow system.
