Effects of deficit irrigation and kaolin application on vegetative growth and fruit traits of two early ripening apple cultivars

Table 5 Interaction of irrigation treatments (I₁ = 100%, I₂ = 85% and I₃ = 70% ETc), kaolin application (K₁ = 0%, K₂ = 3% and K₃ = 6%) and cultivars (Golab and Shafi Abadi) on chlorophyll index (CI), yield and water use efficiency (WUE)
