                        Climate & Soil 
                        Pepper requires a warm and humid climate. Though an annual rainfall of 250 cm is
                        ideal for the proper growth of the crop, it can also come up well in low rainfall
                        areas, if the pattern and distribution of rainfall are conducive. About 70 mm of
                        rainfall within a period of 20 days may be sufficient for triggering of flushing
                        and flowering process in the plant, but once the process is set on, there should
                        be continuous, though not heavy, rainfall until fruit development starts. Any dry
                        spell, even for a few days, within this critical period will result in substantial
                        reduction of yield. Very long spells of dry weather are unfavorable for the crop
                        growth. 
                        The plant tolerates a minimum temperature of 10 ºC and maximum of 40 ºC,
                        the optimum being 20-30 ºC. It can be grown from sea level up to an altitude
                        of 1200 m, but lower altitude is preferable. 
                        Pepper prefers a light porous and well-drained soil rich in organic matter. Water
                        stagnation in the soil, even for a very short period, is injurious for the plant.
                        So, heavy textured soils in locations where drainage facilities are inadequate should
                        be avoided.
