The temperature of irrigation water influences the growth and development of chilli plants. In European countries where paprika is extensively grown (Bulgaria, Hungary) and where stored irrigation water is used, the effect of the temperature of irrigation water is profound. The results of field experiments showed that irrigation with water at 10-12°C interfered with the normal flowering and fruit drop and reduced the yield by 7.6%. Irrigation water at 20—25°C allowed normal growth and development, and increased yield by 10—20% (Ugarcinski, 1964).
