Yield and other agronomic traits in soybean depend on the growth habit. The best maturity group, 00 indeterminate cultivars, compared with semi determinate cultivars for 3 years, out yielded the latter by 9%, possessed greater height and node number but somewhat stronger lodging and better lower bottom pod set. Maturity did not differ significantly within the samples. Correlations were recorded between the yield, growth type and node number. Indeterminate cultivars, in general, require fewer days to start flowering than determinate cultivars. This character is useful in the development of cultivars tolerant to a moderate drought in the second half of the summer. Thus, the most likely model of maturity group 00 variety for Belarus may be an indeterminate, early flowering, full season cultivar.
