Abstract

An investigation was carried out at the Department of Crop Science, Universiti Putra Malaysia (UPM) to examine the effect of PRD using soilless media, a mixture of 70% coconut coir dust and peat (3:2 respectively) amended with 30% rice straw compost. Tomato (Lycopersicon esculentum Mill cv Red Rock) plants were exposed to two different water treatments, which was either well-watered (control) or partially irrigated on half of the roots (PRD). Reduction in water availability in the media with PRD treatment caused a significant decrease in leaf expansion, leaf area and stomatal conductance. Proline was significantly increase with PRD. There was no significant reduction in dry matter partitioning and yield between well-watered and PRD-treated plants. Water use efficiency also was significantly increased with PRD.
