Summary: The use of agrotechnical and chemical measures for the protection of sweet sorghum crops from weeds improves plant growth conditions, eliminates the competition of weeds, and increases the yield of green and dry mass and the estimated output of biogas. Materials and Methods: The field data were obtained in 2014–2016 at the research field of Bila Tserkva National Agrarian University, Ukraine. Soil cultivation, application of soil herbicide S-metolachlor (1.8·lha-1), post-emergence herbicide Prosulfuron (0.02 kg·ha-1) were studied. The trial was randomized in a 3-fold repeat. Results: The effectiveness of the herbicide S-metolachlor application was 56.6–57.7% and the herbicide Prosulfuron – 60.1–60.8%. Using mechanical cultivation destroyed 79.6–80.3% of weeds. Maximum yield of green and dry mass and output of biogas were obtained from the Dovista hybrid in the application of Prosulfuron (69.1 t·ha-1, 16.5 t·ha-1, 6.74 thsd m3·ha-1). Conclusions: The use of agrotechnical and chemical measures for the protection of weeds in sweet sorghum crops contributes to a significant improvement in plant growth, eliminates the competition of weeds and significantly reduces their number. The using only mechanical soil cultivation is less effective, which reduces yields of green and dry mass and the estimated output of biogas, compared with chemical measures.
