Water Management in Horticultural Crops (1+1)

Introduction

• The estimation of the water requirement (WR) of crops is one of the basic needs for crop planning on a farm and for the planning of any irrigation project.
• Water is mainly needed to meet the demands of evapotranspiration (ET) and the metabolic activities of plant, both together known as consumptive use (C or U). Since the water used in the metabolic activities of the plant are negligible, ET is practically considered equal to Cu.
