Periodical Water Production Function of Processing Tomato (Solanum lycopersicum) Subjected to Water Deficit in an Arid Environment

Abstract:

A trial was conducted to investigate water sensitivity index (WSI) and water production function (WPF) of processing tomato subjected to water deficits in an arid environment. The WSI at various growth stages of processing tomato were maintained and a periodical WPF was established based on Blank model. The maximum WSI of processing tomato was marked at flowering with 0.7108 while the minimum was maintained at seedling with-0.0854. In addition, WSI was extremely lower at full fruiting compared to at flowering but notably higher than at seedling. Therefore, processing tomato was extremely sensitive to water deficit at flowering and high levels of soil moisture contents should be maintained while was not sensitive to water deficit at seedling and high levels of water deficits could be controlled without causing yield reduction.
