The field experiment was held on selected areas in the production field in Zhrebino village (South-east Bulgaria) during the 2007 – 2010 period. The test was performed by means of a block method with four repetitions; experimental field area - 15m2 after sunflower predecessor. Four variants i.e seed treatment whit fertigrain start in rate 50 ml/100 kg seeds, leaf treatment whit fertigrain foliar in rate 1l/ha at tillering phase, seed treatment +leaf treatment and untreated control were considered for this study. The aim of the study was to determine the influence of the biostimulants Fertigrain on the elements of productivity and the yield of bread wheatvariety Sadovo 772. The results show: the biostimulant fertigrain have positive effect on the productivity of bread wheat Sadovo 772 variety. The Fertigrain contributes to higher values of structural elements of the yield, such as; length of the spike, number of the spikeletts per spike, number of the grains per spike, weightof the grains per spikeand thousand grain weight. The highest increase in the grain yield was found at variant seed treatment in rate 50 ml + leaf treatment leaf treatment in rate 1l/ha – 18% of the crop grain for the investigated period compared to the untreated control.
