Özet: The straw mulching in wheat production provides important benefits in terms of improving the soil organic matter and quality, the water use efficiency, yield and yield components. The efficiency of the mulching materials could be significantly changed by the factors such as soil and climate conditions, the type, amount, application method and time of the mulching materials. The field experiment was carried out to determine the effects of straw mulching on bread wheat cultivar Adana 99 during 2018-2019 crop season in Kahramanmaraş conditions. The wheat straw as mulch material was used and applied in 4 different rates (0, 3, 6 and 9 t ha-1) and at 3 different stages (soon after planting, at the beginning of stem elongation and jointing stage). The research was carried out as factorial arrangement on the randomized complete block design with 3 replications. In this article, mulch amount as quantative factor was based and the effects of linear and quadratic on biomass, grain yield and harvest index were investigated. It was concluded that the quadratic effect on biomass was significant, while linear effect nonsignificant, both the linear and quadratic effects on grain yield and harvest index were significant and the amount of 3 t/ha straw mulch could be applicable.
