Abstract

During 2011 – 2013 a field experiment with wheat (Trititcum aestivum L.) was carried out in the trial field of Dobrudzha Agricultural Institute. The aim of the investigation was to determine what are the possibilities of growing common wheat in a main wheat production region (Dobrudzha, north-east Bulgaria) using the methods of organic agriculture. The results from the biological growing were compared to the respective results obtained by the conventional method. The following agronomy factors were investigated in both variants of production: three sowing dates (early, optimal and late) x three cultivars (Enola, Aglika and Galateya) x three sowing norms (550, 650 and 750 seeds m-2). In the conventional part of the experiment, suitable fertilizers and pesticides were applied. Wheat was rotated with fodder pea, grain maize and fallow. The soil in the trial field was slightly leached chernozem (Luvic phaeozem) with very good physical and chemical characteristics. The trial was designed according to the split-split plot method in four replications. Wheat productivity in both ways of production was significantly influenced by the tested agronomy factors. Averaged for the investigated period, the yield obtained in the conventional production exceeded the biological method with 11.94 %. The early sowing date was an important prerequisite for higher yields under organic growing. The sowing density was the factor with most variable effect on wheat productivity. Cultivar Aglika demonstrated highest mean productivity under both ways of production. The year conditions had significant effect on grain yield in both methods of growing
