Soybean grains quality (Glycine max (L.) Merr) under different reduced soil tillage treatments

Four different tillage systems were compared in soybean [Glycine max (L.) Merr.] production on one experimental field (chernozem) located in the Baranya region of northeastern Croatia of the 2002 to the 2005. The dry conditions experienced in 2003 have caused exacerbated any negative effects of no-tillage on soybean yield. The 4-year average yield of soybean was significantly lower under notillage (NT) than in the conventional tillage (CT), soil loosening (CH) and disc harrowing (DH) treatments. The soybean oil and protein contents were very in all the tillage systems over the 4-year average. Soybean crude fibre (%) was affected by the main effect of tillage. Averaged over 4–years the crude fibre (%) of soybean grain was greater under NT than in the CT, DH and CH treatments. The ash (%) generally increased as tillage declined. The response of soybean quality traits to the tillage system, varied with the prevailing weather conditions in the particular growing season.
