Tropical region refers to region between the tropic of cancer and capricorn. The average temperature is about 27°C subtropic region summer-hotter and the winter cooler than tropics. Humidity is generally lower.
Based on temperature requirement the fruits crops can be classified as temperate, sub-tropical and tropical fruits.
Tropical fruits – mango, banana, sapota, guava, papaya
Sub tropical fruits – Mangosteen, litchi, acid lime

Arid zone are characterized by sparse and highly variable precipitation, extreme variation of diurnal and on annual temperature and high evaporation. The mean annual rural rainfall varies from 100 mm – 500 mm. Temperature will be as low as 4.4° C and high as 50°C. Although rainfall is low but atmospheric humidity is fairly high.
