Pest regulation: Use reduced tillage in arable fields
A replicated, randomized, controlled study in 2002–2003 in a rainfed wheat field in northwest Turkey found more weeds, but similar numbers of weed species, in plots with reduced tillage, compared to conventional tillage. Pest numbers: More weeds were found in plots with reduced tillage, compared to conventional tillage, in three of four comparisons (36–64 vs 29–49 plants/m2), but there were similar numbers of weed species (14–15 vs 11–13). Methods: Conventional tillage with a mouldboard plough, reduced tillage with a rototiller, or reduced tillage with a disc was used on three plots each (75 x 15 m plots). Fertilizer and herbicide were used on all plots. Weeds were measured in nine quadrats/plot (1 x 1 m quadrats, three times/growing season, before the herbicide was used).

Crop production: Use reduced tillage in arable fields
A replicated, randomized, controlled study in 2001–2003 in a rainfed wheat field in northwest Turkey (same study as (4)) found higher crop yields in plots with reduced tillage, compared to conventional tillage, in one of four comparisons. Crop yield: Higher wheat yields were found in plots with reduced tillage, compared to conventional tillage, in one of four comparisons (rototiller in 2002: 4,055 vs 3,540 kg/ha). Methods: Conventional tillage with a mouldboard plough, reduced tillage with a rototiller, or reduced tillage with a disc was used on three plots each (75 x 15 m plots). Fertilizer and herbicide were used on all plots. Winter wheat was planted in December 2001 and October 2002 and harvested in June 2002 and 2003. Crop yields were measured in three sections/plot (3 m2 sections).
