Skystųjų mikrotrąšų poveikis žieminių kviečių grūdų derlingumui ir kokybiniams rodikliams

Abstract

The experiment was conducted in 2013–2014 year at the University of Aleksandras Stulginskis in Experimental Station of lacustrin light loam on moraine clay Calc (ar) i-Endohypogleyic Luvisol in order to assess the effectiveness of liquid Nanoferti microfertilizers on winter wheat yield and qualitative indicators. The winter wheat variety ʽAda’ was selected for testing. The different configurations of complex fertilizers and fertilizer Nanoferti 6 l ha-1 were used for testing. It was found out that all the fertilizers used substantially increased the yield of winter wheat (0.9 to 1.6 t ha-1) compared to the control during the investigation. The liquid fertilizers Nanoferti in combination with complex fertilizers (N170P60K120) effectively increased winter wheat yield (9,5 t ha-1). It was observed that, liquid Nanoferti fertilizers had no substantial impact on winter wheat yield when compared with conventional fertilization technology. Based on the test results, it can be said that, all of fertilization measures that were used during the experiment, increased winter wheat protein content from 0.8 to 2.4 percentage units. Nanoferti fertilizers increased, but had no significant effect on grain protein content. Regardless of Nanoferti fertilizers, the significant influence on the wet gluten content in winter wheat crops fertilization occurred at higher nitrogen and complex fertilizers rates.
