Soil management techniques influence the biological and physicochemical properties
of the soil and lead to changes in soil quality and cover and thus on crop profitability and yield.
In this study, the effects of short-term tillage and no-tillage methods combined with a chemical
treatment using Glyphosate on weed abundance, selected soil physical properties and yield
components were evaluated in durum wheat under Mediterranean climatic conditions. The
no-tillage (NT) treatment resulted in higher weed community density during wheat cultivation
and moisture consumption than the conventional tillage treatment. The tillage practice and the
application of Glyphosate showed a very high efficiency on weeds. Furthermore, the results
obtained showed a significant variation and effect of the treatments on the soil characteristics.
The application of the no-tillage technique induced a small increase in soil moisture at the seed
germination stage (25.6%), while at the last sampling a small increase was recorded in the CT
treatment (9.5% for CT and 8.8% for NT). The results of the soil porosity, showed during the
whole test period high values in the conventional technique (with or without herbicide
application); but for the resistance to soil penetration, the results showed higher values in the no-till
technique. Finally, the effect of the tillage system on crop yield was evaluated. In our study, the
results showed that significant increases in the number of heads per m2 (351.3 heads per m2
), the
number of grains per head (45.8) and the weight of 1,000 grains (41.2 g) were obtained with the
tillage treatment combined with glyphosate application. When comparing the two tillage
methods, the highest values were always revealed with the tillage technique.
