Irrigation for Chilli or Capsicum Cultivation
Chilli is grown both as rain fed and irrigated crop. First irrigation is given after the transplanting and subsequent irrigations are given 5-7 days interval depending on weather and conditions of soil during summer and rainy season and after .Every 10 to 15 days in winter. The maintenance of uniform soil moisture is essential to prevent blossom .and fruit drops. Bosaocn and Garibaldi (1971) reported that the irrigation when soil moisture tension exceeded one atmosphere increased the yield of the unshared plant, but the number of fruits was unaffected. Flower drop in chillies is a great problem and it depends on the high temperature, low moisture availability, shading and light intensity. Flowers and /or flower bud abscission was increased under short day (day length 12 hours) and high temperature (28 °C to. 33 "Q. Spraying the chilli with Planofix (NAA) at 10 ppm at flower initiation stage and 15 days later (peak flowering) reduces the flower drop and increases the fruit set.
