Care
Bean germinates within 3-4 days. It starts flowering after 45 days. Weeding should be given at 20-25 days and 40-45 days after sowing. The crop should be earthed up after each weeding. Pole-type cultivars grow well on a support made of cane frames or wooden poles connected with strings.
Soil
A good seedbed has friable but compact soil with adequate moisture and free from weeds and plant debris. Acidic soils must be treated with lime before sowing. For field preparation, soil should be ploughed 2-3 times with a power tiller or with a spade. Planking is done during the last ploughing to make friable soil bed for sowing.
Climate
The ideal temperature range for the proper growth of this crop is 10-27°C. Above 30 °C, the flower drop is a serious problem, and below 5 °C the developing pods and branches can be damaged.
