SUITABILITY OF MICRO-IRRIGATION- DRIP IRRIGATION - USED FOR PEPPER GROWTH, IN CONDITIONS OF FIELD CULTIVATION
Abstract
Water gives life and maintains the optimum parameters of ecosystems for a normal and efficient growth, likewise the solar irradiation. Because of the climate changes it is necessary to use rational this two energy sources. Micro-irrigation refers to low-pressure irrigation systems that spray, mist, sprinkle or drip. Drip irrigation is an irrigation method which saves water and fertilizer by allowing water drip slowly to the roots of plants, either onto the soil surface or directly onto the root zone. Drip irrigation helps achieve water conservation by reducing evaporation and deep drainage. It can be adapted to almost any cropping situation and climatic zones. Drip irrigation can be installed as either a surface or subsurface water application system. As with all other irrigation methods, drip irrigation is with both positive and negative impacts on irrigation scheduling, efficiency, uniformity, ecology, crop responses and economic. Peppers prefer a sunny location, long growing season, and fertile, well-drained soil for best yields. Mulch around the plant will conserve soil moisture and reduce weed growth. Irregular watering (over or under) can cause flower drop or blossom-end rot, a dark leathery spot on the bottom of the fruit. It is recommended to avoid heavy fertilization of peppers which encourages excessive foliage growth and delays flowering and fruit maturity. Fertilization was made during the irrigation into the soil.
