What is Water table depth effect on growth and yield parameters of hard red spring wheat (Triticum aestivum L.): a lysimeter study about?

## Abstract Groundwater is a significant source of plant water use since groundwater consumption of plants reduces the volume of surface irrigation water. In this study, groundwater table effect on hard red spring wheat (__Triticum aestivum__ L.) growth and yield parameters were investigated using a lysimeter technique in a controlled environment. Three different groundwater table depths including 30, 60, and 90 cm and a control treatment with surface irrigation were tested. The results showed that water consumption in the 90 cm water table depth was 11% and 31% lower than the water consumption in the 60 and 30 cm water table depths, respectively. Consequently, the groundwater table depth increased, and crop water consumption decreased. Similarly, with the increasing water table depth from 30 to 90 cm in the lysimeter, the crop water use efficiency and crop yield increased by 79% and 71%, respectively. The 90 cm water table produced the highest crop yield, above-ground biomass, and kernel quality compared to 30 and 60 cm water table depths. Quality analysis of the wheat kernels indicated that the kernels from the 90 cm depth had relatively higher starch content, pasting properties,
