Crop Yield and Physicochemical Properties of Wheat Grains as Affected by Tillage Systems

In this study, we aimed to determine the effects of tillage systems (TS) on wheat grain yield, yield components, and physicochemical properties under rain-fed conditions over 2 years (2018–2019) in Kuhdasht region southwestern Iran. The treatments were a combination conventional (CT), reduced (RT), no (NT) based randomized complete blocks with three replications. Wheat yields physical (geometrical dimensions, sphericity, thousand-grain mass (TGM), water absorption (WA), volume (V), density), chemical composition (protein content (PC), (WC), fiber (FC), ash (AC)), surface color parameters (L*, a*, b*), correlations among measured assessed. results showed that components significantly affected by TS (p < 0.01). was higher CT (2.72 t ha?1), significant difference between RT (1.76 ha?1) NT (1.20 ha?1). highest TGM (49.19 g) achieved CT, followed (43.41 g), lowest (39.17 system. had certain grains grain, size, shape, values than all experimental years. resulted WA, while from NT. influence density grains.
