The effect of biological preparation Fertenat on spring wheat productivity and quality

Abstract

The research of the biological preparation Fertenat effect on spring wheat was investigated at the Experimental Station of Aleksandras Stulginskis University in Calc(ar)i-Epihypogleyic Luvisol (LVG-pw-cc) during 2013–2014. Spring wheat was grown according to the requirements of the National Agricultural Products Quality System. Biological preparation Fertenat had a significant effect on the elements of spring wheat yield structure and the values of chemical composition parameters, influenced by the rates of biological preparation and meteorological conditions. A strong correlation was found between the Fertenat rates and spring wheat plant stem and ear length, grain number per ear, total and productive stem number of one plant and 1 000 grain and hectolitre weight. The correlation between the biological preparation rates and protein, wet and dry gluten was strong as well. A strong correlation between the biological preparation rates and starch amount in grain was found in 2013, while in 2014 this correlation was moderate. The application of biological preparation Fertenat increased the spring wheat yield by 0.05–0.30 t ha^–1 or by 2.29–13.76 percent units and by 0.02–0.41 t ha^–1 or 0.40–8.23 percent units. The application of 6 l ha^–1 and higher Fertenat rates significantly increased the spring wheat yield. Small 1–3 l ha^–1 rates are inefficient. The correlation between the Fertenat rates and grain productivity was strong.
