Abstract

The main objective was to evuate the efficiency of biological products for winter wheats pruductivity. The investigation was made in 2014 – 2015 years in Aleksandras Stulginskis University Experimental station on IDg8 - k (LVg – p – w - cc) – calcareous shallow luvisol (Calc(ar)i-Epihypogleyic Luvisols). Wheat preseeding culture – winter wheats. Biological preparations fall (spray biological agents for 3 years in a row on the preceding crop (winter wheat) stubble: 1. Control; 2. Amalgerol - 3.0 l ha -1 (biological agents spray spring winter wheat at BBCH 30 stage): 1. the untreated control; 2. Amalgerol - 3.0 l ha-1; 3. Nitro Team - 1.0 l ha-1; 4.NPK Magic - 1.0 l ha -1. The maximum yield additive gave autumn spraying agent Amalgerol 3 years in a row and spring spraying nitrogen bacteria Nitro Team, compared with the control, the yield was 1.31 t ha-1. This is 14.41% more than in the control variant. The biggest mass of 1000 seeds were using Amalgerol and NPK Magic combination, and in comparison with the control margin of 1.2 g, which accounted for 2.62% more than the raw box
