Determine the effect of row spacing on productivity corn on silageand biogas output. Field experiments were carried out in 2012–2015 on the experimental field of the BilaTserka National Agrarian University. Studied four hybrids of maize Pivicha (FAO 180), Galatea (FAO 260), Moniсa 350 MV (FAO 380), Bystrytsia 400 MV (FAO 450) and two widths of the rows 45 and 70 cm. In unfavorable climatic conditions, the yield of green mass decreased by 1,5–10.7 % in variants with a row spacing of 45 cm, compared with 70 cm. No significant influence of the row spacing on the calculated biogas output was noted. High index of yield green and dry mass, biogas output showed a hybrid corn Bystrytsia 400 MV, but in the years of research, there was no significant difference with the hybrid Moniсa 350 MV. By regulating the area of nutrition of corn plants, it is possible to control the formation of economically valuable traits, the level of productivity and the biogas output.
