The field experiment was conducted in field at Regional Research Centre, Amravati during kharif season in 2018-19. The experiment was conducted in split plot design with three replications, two varieties of soybean JS 20-34 and RVS 24 in main plot and four land configurations of spacing under ridges furrow planting 45 x 5 cm, 45 x 10 cm, 45 x 20 cm and 45 x 30 cm) in sub-plot. The observation on dry matter was recorded at 30 DAS, 60 DAS and at harvest, CGR and RGR on 30-60 DAS and 60 DAS-at harvest. The observation on Yield attributes viz., branches per plant, pods per plant, seed index, seed yield kg/ha, straw yield kg/ha and harvest index were recorded at the time of harvesting. Highest no. of pods per plant was recorded in JS 20-34. The crop geometry was observed highest pods plant-1 in 45 x 30 cm followed by 45 x 20, 45 x 10 and lowest in 45 x 5 cm spacing. This may be due to less competition amongst the plant, maximum aeration and sunlight. Seed index was recorded no significant difference in varieties and crop geometry. Soybean was recorded significantly higher seed yield and straw yield in variety JS 20-34. No significant differences found in crop geometry but higher seed yield was observed in 45 x 10cm spacing. The lowest cost of cultivation was noticed in variety RVS 24 while highest GMR, NMR and B:C ratio was observed with JS 20-34. In respect of different plant geometry, lowest COC was observed with 45 x 30 cm spacing while highest GMR, NMR and B:C ratio was recorded with 45 x 10 cm spacing
