| Abstract | The article investigates and substantiates the peculiarities of the influence of the substrate on biometric indicators, chemical composition, yield and quality of microgreens of vegetable crops. Taking into account the trends in the development of innovative technologies in the world and in Ukraine, an important task today is the expansion and systematization of the consumer characteristics of microgreens of vegetable crops. The results of a complex study of the influence of the substrate on the microgreens of leafy lettuce, radishes, and mustard, presented in the article, confirm the complete suitability of extracting greens in closed soil. Taking into account the trends in the development of innovative technologies in the world and in Ukraine, an important task today is the expansion and systematization of consumer characteristics of microgreens of vegetable crops. The results of a complex study of the influence of the substrate on the microgreens of leafy lettuce, radishes, and mustard, presented in the article, confirm the complete suitability of extracting greens in closed soil. Studies have shown that mustard plants grown on a coconut substrate had the highest growth rates – 6.97 cm, radish plants on a coconut substrate had slightly lower rates – 6.49 cm. The lowest growth rates were noted in microgreens of leaf lettuce on mineral wool – 4.54 cm. It was established that the use of different types of substrate had a significant effect on plant weight and productivity. On average, for three years, the maximum mass was achieved by growing lettuce on a coconut substrate – 14.02 g, radish on a coconut substrate – 71.86 g, and mustard on mineral wool – 35.86 g. Higher productivity was observed in leaf lettuce and radish when using coconut substrate Thus, in leaf lettuce, the yield was at the level of 1.85 kg/m2, in radish – 5.72 kg/m2, in mustard, the best results were obtained with the use of mineral wool – 4.82 kg/m2. A slightly lower yield was obtained when using mineral wool in lettuce – 1.57 kg/m2, in radish – 5.39 kg/m2, in mustard on a coconut substrate – 4.82 kg/m2. It was determined the content of indicators of the chemical composition of greens and proved that the types of substrate did not have a negative effect on the change in the chemical composition of vegetable plants. Thus, the highest content of dry matter was observed in leaf lettuce when using mineral wool and amounted to 9.3 %, respectively, on the coconut substrate, the indicator of the content of dry matter was the lowest – 5.4 %. Growing microgreen radish on mineral wool accounted for 10.2 % of dry matter, respectively, on coconut substrate – 8.4 %. The dry matter content of microgreen mustard was the highest when using the coconut substrate and amounted to 9.5 %, the lowest on mineral wool – 8.9 %. The most significant difference in the content of green pigments was found in mustard on mineral wool and radish on coconut substrate, which was 19.68 mg/g and 18.85 mg/g, respectively. | ||
