Soybean development and maturity is related to day length or, more specifically, duration of darkness. If their average maturity is a 3.
When deciding on the proper maturity consider the following. Maturity of a soybean variety is the length of time from planting to physiological maturity just prior to harvest. Maturity group zones were developed to define where a soybean cultivar is best adapted.
The maturity group is determined by abiotic factors. The main factor is photoperiod, followed by temperature, age and other environmental factors.

Shorter days trigger soybean development; however, when daylight increases springdevelopment slows. Flowering will differ significantly due to photoperiod, which is a constant value for a specific time period, location and genotype. More than 45 years ago scientists Scott and Aldrich delineated and published hypothetical optimum maturity group zones across the U.
