Descripción
The aim of this study was to compare the profitability of traditional cultivation of corn for grain dry, wet for the purpose to distilleries and the cultivation of corn silage using it for energy purposes as feedstock for the biogas plant. The highest yields were obtained in 2014: 9.70 t ha dry grain, 11.50 t/ha of wet grain and 55 t/ha of silage for the purpose of biogas. Gross margin of 1 ha of maize ranged from: 67.90 PLN/ha in 2015 (corn for silage into biogas) to 4308.80 PLN/ha (dry grain maize) in 2013, and was determined by the direction of growing corn and years of research. The income from 1 ha of crops including direct payments ranged from -2.60 PLN/ha in 2015 (the cultivation of grain dry) to 3060.30 PLN/ha in 2013 (crop silage into biogas). The biggest indicator of profitability over the years studied was achieved in the cultivation of corn for grain wet.
