Spring Wheat Cultivation Using a New Bioproduct

Spring wheat is a strategically significant agricultural crop all over the world. Increasing yields of the crop need increasing use of the mineral fertilizers and chemical fungicides – using which becomes less and less popular. They are being substituted with various bioproducts being developed all over the world, including Russia. All-Russian Research Institute of Reclaimed Lands (VNIIMZ) has created a novel bioproduct – LBP – featuring physiologically significant amounts of growth factors and nutritive elements favorable for the plants. This work evaluates an LBP effect on spring wheat, Irgina sort, when using LPB as a supplementary fertilizer with a mineral fertilizer as a basic one. The research was carried out in microplot experiments at a VNIIMZ’s test site, Tver Region, Russian Federation, in 2009-2010. Among all options studied, a 0.1 l/sq.m LBP dose (added by spraying on bushing-out and earing plants) proved to be the most effective. That option yielded 16.31 metric centners/hectare, which is 27.3% higher than the same without LBP is. A grain quality analysis showed the following nutritive value rise compared to references: cellulose, oil and calcium (CaO) increased by 10…12%, 9…10%, and 10…12%, respectively. Soils of the plants treated with LBP generally contained more nitrogen compounds, less amylolytic microorganisms (competing for nitrogen) and Fusarium wilt ones - which totally provided better conditions for the spring wheat growth.
