Description and Adaptation

Soybeans have adapted to a wide range of soil types in south eastern Saskatchewan. Ideally, they are grown on loamy soils and may also perform well on clay soils if conditions are favourable for rapid seedling emergence. Soybean is sensitive to drought, so sandy soils are not usually conducive to satisfactory performance.

Soybean is a warm season crop requiring sufficient heat to perform well and mature in a timely fashion. Soybean varieties in Saskatchewan need between 2325 and 2450 corn heat units. This limits production of soybean to areas receiving sufficient heat.

The two-year (2011-2012) mean yield of the check variety 23-10RY was 42 bushels/acre. Typically, on-farm yields are between 25 and 30 bushels per acre. Corn Heat Unit ratings are assigned by individual companies to assist growers in selecting varieties suitable for their area. Growers should not rely on only one source for judging maturity.
