Bioethanol producing from sorghum crops

Abstract

The relevance of the article lies in a comprehensive analysis of the trend in the production of biofuels from crop products in Ukraine and other countries of the world. The purpose of the research was to justify on the basis of research by both their own and many authors that sorghum varieties are extremely important in cultivation due to changes in soil and climatic conditions. When conducting research, we used generally accepted methods, techniques and DSTU, in particular: the method of comparison, analysis and synthesis, laboratory and field. Computer methods of information processing and visualization of research results using the Microsoft Office program were also used. According to the results of research, it was found that with less favorable temperature conditions and moisture supply in 2020 yr., grain sorghum crops formed a yield depending on the hybrid in the range of 2.1-6.9 t/ha, in a more favorable year for these indicators in 2021 yr. it was at the level of 6.9-14.5 t/ha, and on average for two years it was in the range of 4.5-10.7 t/ha. Performance stability was determined in the U 60117 IG and Bianca hybrids. On average, over two years, the theoretical yield of biofuels, depending on the hybrid, ranged from 2216 up to 5199 l/ha with a starch content in the grain of more than 75%. The highest estimated alcohol yield per unit area was in the grain sorghum hybrid U 60116 IG, which combines a stable yield (10.7 t/ha) with a high starch content in the grain (75%). Treatment of sugar sorghum crops with biologics and microfertilizers had a positive effect on the yield of structural units per hectare: compared to the control, the yield of leaves during organic balance processing increased by 2.66 t/ha, the yield of panicles – by 1.56 t/ha, and stems – by 3.64 t/ha. The increase in the conditional yield of sugars relative to the control of treatment with Quantum microfertilizers was 0.354 t/ha, organic balance – 0.417 t/ha, and with their combined action – 1.143 t/ha, which was the maximum value
