• The ideal temperature at the time of the sowing is between 10°C to 15°C and at the time of ripening and harvesting is  21°C to 26°C.
• A frost-free period of about 100 days is required for its cultivation.
• It grows best in a well-drained loamy soil. Particle size, distribution of the soil, and the relative quantities of the sand, silt, and clay size determine the loamy soil.
