Abstract

There is often immediate need by the farmers in different parts of the world to obtain simple technology in cultural practices that can be used to alleviate environmental stress conditions in order to sustain yield quality and to increase plant water use for the agricultural products. However the use of organic matter amended composts as most cost effective and environmentally sound alternatives for organic waste recycling will be crucial for increasing water use and other agronomic aspects. This study was conducted at Hydroponics Unit UPM Malaysia to evaluate the use of rice straw compost under two stress cycles with different growing media namely soilless media \coca nut coir dust and peat 3:2\ and greenhouse soil \top soil sand and peat 2:1:2\ for improvement of yield quality and water use efficiency WUE of tomatoes grown under protected environment. The experiment was designed as four-by-two factorial in a complete randomized with three replicates. The two factors were water regime \well watered or stresswithhold water\. Others factors were the media mentioned above with 30 compost or without. The results indicated that addition of rice straw compost significantly increased yield and WUE in both media wheres water deficit significantly decreased yield and WUE on most of the treatments. The increase in total yield and WUE in both media might be due to the increasing of total carbon or/and to nutrient efficiency. However significant interaction wa obtained with media and water in plants dry biomass total yield fruit diameter and WUE. The results indicated that soilless media was not affected by the stress regime in most of these parameters. This suggest that soilless media increased water holding capacity and others physical properties batter than greenhouse soil. The results also indicated that media drying decreased leaf water potential stomatal conductance as well as plant dry biomass whereas increased proline accumulations with slightly differences within the different media.
