The work was done in Uberlândia (MG) to evaluate the performance of seven soybeans cultivars sowed in four different times: October 30th, November 15th, December 14th and 31st during the 2001/2002 season. The cultivars utilized were: DM-118 early-maturing, DM-247, DM-Victoria, DM-339, medium late cycle and DM-309, DM-98C81 and DM-Noble cycle Late. The statistical design was a randomized blocks in a factorial scheme (7 cultivars x 4 times) with three replications. The evaluated characteristics were: yield, number of days for flowering, number of days for maturing, plant height, first bean height and plant laying. For the most evaluated cultivars, sowing beyond December 14th in Uberlandia region presented yield losses for earlier cultivars as DM-118 as well for the later ones as DM Vitória, compared to sowing in 30th October. The time for flowering and maturing and plant height had effect on the yield.
