Perlite Affects Some Plant Indicators and Reduces Water Deficit in Tomato

Description
Summary:Water deficit in semi-arid areas is a limiting factor affecting crop production and quality. Suitable water regimes, and use of perlite to store moisture, may help overcome drought. The experiment was conducted from March to July 2016 in a field in Diyala, Iraq. The objective was to determine effects of tomato (Solanum lycopersicum L.) genotypes 'Bobcat,' 'Finenss,' and 'Hadeer'; irrigation levels of 50% and 100% based on field capacity, and addition of perlite, at 0%, 5%, and 10% as a volumetric percent of soil, on plant growth and development, and water management. Combinations of factors resulted in 18 treatments. The 'Finenss'+50% irrigation+10% perlite produced the least proline in leaves. Treatment 'Bobcat'+50% irrigation+10% perlite produced the longest roots and least root dry weight. Treatment 'Bobcat'+100% irrigation+5% perlite had the highest water use efficiency and can likely be recommended as an irrigation management strategy for tomato production under deficit irrigation. By using this strategy, approximately 50% of irrigation water can be conserved without reduction in yield. Perlite decreases adverse effects of water deficit and improves growth and production at normal and deficit conditions.
