Research review on Irrigation scheduling and water requirement in citrus

Abstract

Citrus is the main fruit group grown in tropical as well as sub-tropical climate of more than 150 countries in the world. Irrigation scheduling and water requirement of the citrus crops are one of the main concerns of the modem citrus fruit production irrespective of availability of natural resources. A large number of research findings have emerged world over on irrigation scheduling and water requirements of the citrus based on available soil water content and its depletion and based on pan evaporation replenishment. The research review of the literature has revealed best promising results on irrigation scheduling based on depletion patterns of soil available water content, irrigation schedules of various citrus crops and fertigation. Irrigation water management with proper water use is one of the prime concerns of modem horticulture irrespective of soil and water resource availability. A variety of recommendations have reviewed the world over on irrigation scheduling based on analysis of meteorological parameters, evapo-transpiration, depletion of available water content, soil and leaf water potential. The review of the literature has revealed best promising results on irrigation scheduling based on depletion patterns of soil available water content. Similarly, irrigation scheduling has shown good responses on growth, yield, and quality compared to calender method of irrigation schedules. The present status of the review of irrigation scheduling and water requirement of citrus cultivars is clearly presented in this research review article.
