The switchgrass productivity at growing with different row widths on slopes of Southwestern Forest Steppe

Goal. To determine the productivity of switchgrass as a raw material for production solid types fuel when it is grown on slopes with different row widths. Methods. Field — to find out effect width spacing switchgrass; laboratory content dry matter; statistical assess reliability obtained results; comparative-calculation energy efficiency. Results. Phenological observations conducted during growing season plants 7th–9th did not reveal any difference in duration plant development phases variants experiment factor affect that indicator. Plant growth began 3rd decade April, seed ripening 1st October. Research determining biometric parameters plants, season, proved grew and developed best at 0.45 m. In this version experiment, they had an average height 195 cm, which was 21 cm more than areas 0.15 However, number formed leaves plant. When switchgrass, highest crop yield noted variant m: amount green mass 19.5–25.9 t/ha, 2.1–6.7 t/ha compared where At same time, 12.43–15.54 matter obtained, output 201.9–274.2 MJ/ha. Conclusions. The indicators 7th 9th years life were provided by use
