| Abstract | Goal. To determine the formation of productivity of different varieties of rod-shaped millet. Methods. Field, measurement, calculation and comparison, analysis, statistical. The results. The article presents the results of studies of the influence of the maturity group of millet varieties on the formation of productivity and yield of solid biofuel and energy from biomass. It was investigated that the highest yield of raw and dry mass was established in the Kanlow variety sample, which was 25.8 t/ha and 13.2 t/ha on average over the years. Late-ripening and mid-ripening varieties had the highest yield - from 15.2 to 19.0 t/ha. In Cave-in-Rock, Shelter, and Carthage samples, this indicator was 18.5 t/ha, 19.0 t/ha, and 18.7 t/ha, respectively. The lowest yield of the Dakota variety is only 10.5 t/ha. In all other varieties, the yield of raw mass varied from 14.9 to 15.2 t/ha. It was studied that the most productive varieties formed a high yield of biofuel. The Kanlow variety, which belongs to the group of super-late ripeners, formed a yield of 11.5 t/ha and provided a biofuel output of 12.8 t/ha, energy – 211.30 GJ/ha. It was established that the varieties of the late-ripening and mid-ripening group provided yield from 8.5 to 10.5 t/ha, solid biofuel output from 8.0 to 11.5 t/ha, and energy output from 156.53 to 189.43 GJ/ha. Early ripening varieties Forestburg, Nebraska and Dakota formed the lowest rates of biofuel and energy yield. Conclusions. The productivity of millet depends significantly on the maturity groups of the varieties and the weather conditions of the growing season. It was found that the higher the height and number of stems, the higher the biomass yield. The highest content of raw and dry biomass was noted in varieties of the late-ripening and medium-ripening groups. The Kanlow sample produced the highest phytomass yield, while the Dakota and Forestburg samples had the lowest yield, which was related to the length of the growing season and maturity group. | ||
