Abstract
The aim of this three-year field experiment was to determine how simplified (reduced) pre-planting tillage and different weed control methods impact the yield and selected quality parameters of spelt grain (Triticum aestivum ssp. spelta L.). Conventional tillage and three variants of reduced tillage (RT) were tested. The second experimental variable (weed control) had three variants: mechanical weed control (M), combined mechanical + chemical treatment at full herbicide rate (MC 100%), and combined mechanical + chemical treatment at 25%-reduced herbicide rate (MC 75%). The mechanical method consisted of harrowing the wheat crop in the fall and spring. The results showed that the wheat yields obtained under reduced pre-planting tillage were comparable to those under conventional tillage. However, the grain quality parameters proved to be worse under the reduced tillage regimes. Herbicide applications, both at full and reduced rates, significantly improved grain quality parameters and yields compared with mechanical-only weed control. In particular, the herbicide-treated crops boasted higher values of thousand-kernel weight and grain weight per ear.
