This study was conducted to determine the effect of different mulch materials on plant water consumption, yield, fruit quality, vegetative growth, and weed control and soil temperature of Braeburn apple variety grafted onto M9 rootstock in Eğirdir Fruit Growing Research Station in 2010-2011. The experimental design was a randomized block design with three replications. Three different treatments were determined as two different mulch materials (white fabric, black plastic covering) and control (without any mulching). Irrigation water was applied by using drip irrigation system in 7 days intervals. Amount of irrigation water to be applied in the each irrigation was determined as water amount needed for raising the soil moisture to the field capacity in 0-60 cm soil depth. As a result, substantial water saving has been provided from both of the mulch materials (%< 22-28) in comparison with the control treatment. The yield results showed statistically significant difference (p<0.05) among the treatments only in the second year. The highest red colour density value, which is an important criterion in apple marketing, was obtained from mulching with white fabric for both years. It was determined that mulch applications with these two materials were positive effects on vegetative growth and they were very effective on weed control. Soil temperature measured in the treatment used white fabric was found 1-2°C lower in comparison with control treatment, while it was found 3-4°C lower in comparison with the black plastic covering.
