Abstract

The aim of this work was to determine the effect of deficit irrigation on the physical and elasticity properties of date fruits (Phoenix dactylifera, cv. Khudary) during three stages of repining (Khelaal, Rutab and Tamr) for two years (2014 and 2015) to predict the package height of date fruit. Four irrigation treatments were studied: (ET1): 1.0 ETc ) one time potential crop evapotranspiration(, ET2: 0.85 ETc, ET3: 0.75 ETc and ET4 :0.65 ETc). The physical properties included date mass, volume, dimensions, moisture content, bulk density, solid density, flesh thickness, flesh mass and elasticity of fruits. The elasticity properties of fruit included young's modulus of elasticity (E), firmness coefficient (FC), bio-yield stress point (σb), bio-yield strain point (εb), rupture stress point (σr) and rupture strain point (εr). The results showed that the deficit irrigation affected both physical and mechanical properties, therefore, affected on package height of date fruits. The maximum packing heights for Khellal, Rutab and Tamr were 6360.51, 654.2 and 1850 mm with ET1, ET2 and ET3, respectively. While, the minimum packing heights for Khellal, Rutab and Tamr were 3738, 206.6 and 1411 mm with ET4, ET3 and ET1, respectively.
