Beans do not tolerate standing water. On average, moisture is adequate across all of Manitoba for producing beans. Kidney and cranberry beans require an extra 10 to 14 days to reach maturity, and should be grown only in south-central Manitoba. May. Any damage below the cotyledon will cause the bean plant to die.
Beans are a warm-season crop.
The optimum temperature for growth is 24 C, and temperature extremes can result in reduced growth. Field bean growth and development stops when temperatures drop below 10 C. Types of Field Beans Field beans can be generally classified as either bush or vine types. Vine-type field bean varieites have indeterminate growth, meaning they continue to grow, flower and set pods as long as temperature and moisture permit. Field bean plants exhibiting indeterminate growth tend to have pods set close to the ground and are usually grown in row-crop situations. The bean seed has two cotyledons and the embryo.
