Soil and Climate

Soil
Pumpkin is sensitive to acidic soils. A deep well drained loamy soil is preferred. Sandy loams are good for raising early crop whereas clay loams are good for high yield. Both should be with ample organic matter content. The long tap root system is adapted to its growth in river beds. The best pH should be 6.0-7.0.Soil¬temperature should not go below 10°C and maximum beyond 30°C, the optimum range is around 20°-25°C. Soil-moisture should be at least 10-15% above the permanent wilting point.

Climate
The plants can be grown successfully between temperature ranges of 25°-30°C. Above 40°C and below 15°C the growth of the plant will be very slow and the yield goes down. It does not tolerate frost.Pumpkin requires a long and warm growing season. It can be grown in relatively cooler climates than the other cucurbits. Short-days, low-night temperature and high-relative humidity is best for pumpkin production.
