Partitioning simple correlation coefficient between seed yield/plant and some of the yield components at hravest in nne soybean cultivars revealed that pods dry weight/plant and number of seeds/plant were the most effective contributing components to seed yield. Variation since their contributions were 42.4%, 71.21%, 487% and 28.16% for pods dry weight/plant and 9.05%, 1.83%, 11.2% and 16.26% for number of seeds/plant in 15 May, 1 and 15 Jurie sowing dates, respectively. Whereas, the R2 were 99.91%, 99.94%, 99.85% and 99.991% and the residual effects for sowing date we 0.09%, 0.06%, 0.149% and 0.009%, respectively.
