Thermo classification

V. Thermo classification:
On the basis of temperature, vegetable crops may be grouped into cool and warm season crops. In cool season crops, the edible parts are mainly root, stem, leaf and immature flower parts. Whereas, in warm season crops edible part is mainly fruit with exception of pea and broad bean which are cool season crops. The cool season crops grow well when the monthly mean temperature does not exceed 210 C. They thrive best if the monthly mean temperature is 15-170 C. The warm season crops on the other hand grow best when the monthly mean and average maximum temperature are 50 to 60C higher than for the cool season crops. The average monthly minimum temperature should not be below 90C to 100C for the warm season crops.
