The Waterlogging Tolerance of Wheat Varieties in Western of Turkey

Abstract EN

This research was conducted to determine the wheat varieties against waterlogging which was clearly increased in recent years.

For this purpose, this study was performed at Field Crops and Soil Science Department of Agricultural Faculty of Adnan Menderes University during wheat growth stages of 2007-2008.

The experimental design was randomized complete block design with split split plot arrangements.

The main plots were temperature applications (heat and normal), the growth periods (Zadoks scale; GS14, GS32, GS14 + GS32, and control) were split plots and varieties were split-split plots.

The eight different wheat varieties were evaluated in the pots.

The waterlogging was performed during GS14, GS32 and GS14 + GS32.

In a pot experiment, plants were subjected to waterlogging to the soil surface for 10 days.

All applications and varieties decreased the single plant yield.

The waterlogging caused a yield loss compared with wheat grown on well-drained soil.

In this study, the crop loss due to waterlogging is highly temperature dependent.

The severity of the effects of the waterlogging depends on the growth stage of the plot.

When all applications were compared with control by means of yield performance, Sagittario and Basribey varieties were less affected than the others.
