The ecological requirements for tomatoes are moderate rainfall of about 760-1300 per year. Too much rainfall increase fungal diseases and prolong maturity. It is a warm season crop that requires clear and dry weather. The optimum temperatures are 18-29 Cent-grate. A high relative humidity encourages diseases. Elnino rains scale up this requirements hence limiting tomatoes production.
Effect of this is short supply of tomatoes hence lycopene, a pigment found in tomatoes. Lycopene protects the cells of the prostate from oxidation and abnormal growth.
