Turmeric prefers a warm and humid climate. It can be grown in diverse tropical conditions within a temperature range maintained at 20-30 °C with a rainfall of 1500 mm or more per annum or under proper irrigation conditions.
Turmeric growth ceases when, the temperature falls below 20°C and hence early planted turmeric gives a good yield. Although turmeric grows well in different types of soil ranging from light black loam, red soils to clayey loams, rich loamy soils which are well drained. Turmeric cannot stand water stagnation or alkalinity. Any problem related to temperature, irrigation can easily be sorted in polyhouse by regulating the growing conditions, irrespective of turmeric growing season.
