Sowing time for common bean

Phaseolus vulgaris L.

The choice of sowing time for common bean is determined by its high heat requirement and critical sensitivity to frost, requiring soil to warm up to 12–14 °C.

In the reference 17 varieties crop Common bean, where this is mentioned in the description.

For common bean, the temperature regime is a critical factor: sowing begins when the soil at a depth of 10 cm warms up to 12–14 °C and the established average daily air temperature is above 15 °C. The crop is extremely sensitive to low temperatures; therefore, prolonged exposure of seeds to cold, moist soil or the impact of late spring frosts on seedlings leads to decay and a sharp decrease in field germination.

The choice of sowing dates depends on the purpose of the crop and the region: to obtain grain, sowing is carried out as early as possible to ensure maturation before autumn cooling. In southern regions, sowing begins in mid-April, while in northern regions it lasts until the end of May or early June; when choosing the timing, it is necessary to consider the moisture balance due to the deep placement of seeds at 4–7 cm. Under unfavorable conditions, pre-sowing irrigation is practiced, and the deadline for sowing in a number of zones is considered to be mid-July, which requires the use of early-maturing varieties.
