Energy productivity of sugar sorghum in the central part of the Forest-steppe of Ukraine depending on the harvesting time

Due to global climate change, sugar sorghum (Sorghum saccharatum), due to its fast growth rate, early maturation, efcient use of water and limited need for fertilizers, is the most promising plant for biofuel production in the world. The article presents the results of the study on establishing the dependence of sugar sorghum energy performance indicators on varietal characteristics (varieties 'Silosne 42' and 'Favorit' and hybrids 'Dovista' and 'Medoviy F1') and the green biomass harvesting time. The purpose of the research was to establish the influence of varietal characteristics and harvesting time on sugar sorghum energy productivity in the zone of unstable moisture in the Central part of the Forest-Steppe of Ukraine. The research subject is sugar sorghum energy productivity indicators (yield of green biomass; sugar content of juice; yield of biogas, bioethanol, solid biofuel; total energy yield). The studies were carried out during 2016–2020 in the zone of unstable moisture in the central part of the Forest-Steppe of Ukraine in the conditions of the Bila Tserkva Experimental Breeding Station of the Institute of Bioenergy Crops and Sugar Beet of the National Academy of Sciences of Ukraine. It has been established that the highest yield of biofuel and energy (up to 791.8 GJ/ha) is achieved under growing sugar sorghum of the 'Dovista' hybrid, provided that its biomass is collected in the phase of full seed ripeness (early October). It is advisable to start collecting sugar sorghum biomass for biogas after the panicle throwing phase. To ensure the maximum yield of bioethanol, the optimal time for harvesting green biomass of sugar sorghum is the second decade of September – the frst decade of October. The maximum yield of solid biofuel is achieved under harvesting biomass after the phase of waxy ripeness of grain. The formation of the yield of green biomass of sugar sorghum was more influenced by weather conditions (47.4 %), the influence of varietal characteristics (17.8 %) and the timing of harvesting (12.8 %) was less. But the energy yield was most influenced by the timing of harvesting biomass (37.4 %). A close linear correlation between the energy output and the yield of green (R2=0.81) and dry biomass (R2=0.99) was established. The most ecological plasticity in terms of the total energy yield per unit area turned out to be the 'Medoviy F1' hybrid (b=1.62), which indicates the prospects of growing this hybrid under favorable weather conditions and high level of agricultural technology.

 Key words: sugar sorghum, varietal characteristics, harvesting time, energy yield, biofuel yield, productivity.
