Abstract An experiment was laid out for cherry tomato plant during two successive growing seasons, namely 2004/2005 and 2005/2006 in the Experimental Farm of Arid Land Agricultural Services and Research Center (ALARC), Faculty of Agric, Ain Shams University, Shobra El- Khima, to study its response to different levels of water regime in perlite, sand plus rice husk (1: 1 v/v ) and karenna substrates using vertical and horizontal bag types with their interactions on growth, yield attributes, physical properties, chemical properties and water relations. The experiment was laid out in A split- split plot design in complete randomized block system with three replicates. The levels of irrigation regime were 80%, 100% and 120 % from class A pan evaporation, data for Shobra El.-Khima region. Plants were grown in substrates, i.e. perlite, sand mixed with rice husk (1: 1 v/v) and karenna using two types of bag, i.e. vertical and horizontal in unheated single span plastic house. The results. |
