Formation of sugar sorghum productivity as bioenergetic culture depending on the mineral nutrition
Journal Title: «Таврійський науковий вісник» - Year 2018, Vol 99, Issue
Abstract
Influence of different doses of mineral fertilizers on the formation of sugar sorghum productivity and the output of biogas are presented in the article. The maximum content of dry matter in sugar sorghum was noted in the phase of waxy grain maturity and was 20.3-23.0% in the variety Silosne 42 and 21.8-23.9% in the hybrid Dovista. An augmentation in the doses of mineral fertilizers influenced the increase of the dry matter content in sugar sorghum plants, growth in the yield of green mass and the calculated yield of biogas. There is a strong correlation r = 0.95 between the content of dry matter and the calculated yield of biogas, and r = 0.92 between the content of dry matter and the yield of green mass. 3 The highest yields of green mass (82.7 t/ha) and calculated yield of biogas (7.9 thousand m /ha) are obtained from the hybrid Dovista in the variant N100P80K80, which confirms the efficiency of using sugar sorghum as material for the biogas production.
