| Abstract | The article investigates and substantiates the peculiarities of the influence of the sowing period on biometric indicators, chemical composition, yield and quality of microgreens of radish and mustard vegetable crops. An important task today is the expansion and systematization of consumer characteristics of microgreen radish and mustard. The results of a comprehensive study of the impact of sowing time on radish and mustard microgreens presented in the article confirm the complete suitability of growing vegetables on microgreens in the off-season period. Studies have shown that radish plants sown in the 1 decade of December possessed the highest growth rates and the plant height was 5.15 cm, in mustard the highest indicators were observed for sowing in the ІІІ decade of January – 6.16 cm, which is 1.07 cm higher than the control. Radish plants had the lowest indicators for sowing in the ІІ decade of December - 4.49 cm, which is 0.6 cm less than the control. Accordingly, in mustard, the lowest indicators were observed for sowing in the ІІІ decade of November – 5.50 cm, which exceeded the control by 0.41 cm. It was established that the time of sowing had a significant effect on the mass of plants and the level of productivity. On average, over three years, the maximum mass of radish was obtained for sowing in the ІІ decade of December – 58.19 g, which exceeded the control by 2.9 g. For mustard, the highest indicators were obtained for sowing in the І decade of January – 34.23 g, which 21.06 g less than the control. Higher productivity was observed in radish for sowing in the ІІ decade of December – 5.67 kg/m2, and for mustard for sowing in the ІІІ decade of December – 4.77 kg/m2. Radish and mustard plants sown in the ІІІ decade of January had the lowest productivity indicators and were, respectively, 5.08 kg/m2, which was 0.33 kg/m2 below the control and 4.37 kg/m2, which was 1.04 kg/m2 below the control. The conducted studies showed that depending on the time of sowing, the parameters of the chemical composition of greens change. So, the highest content of dry matter was observed in radish for sowing in the II decade of March and amounted to 8.8 %, respectively, in mustard, the indicator of the content of dry matter was higher than for sowing in the III decade of December – 9.7 %. The lowest rate was obtained for radish sowing in the І decade of March – 8.0 %, and mustard – in the ІІІ decade of March – 8.2 %. The most significant difference in the content of green pigments was found in radish for sowing in the ІІІ decade of December and in mustard for sowing in the ІІ decade of March – 19.88 and 18.59 mg/g. The chemical composition of radish plants was characterized by a higher amount of sugars – 1.66 % for sowing in the ІІІ decade of November and the І decade of December. Mustard, in turn, had higher indicators for sowing in the ІІІ decade of November – 9.71 %. The content of vitamin C was higher in radish for sowing in the І decade of March – 20.35 mg/100 g, in mustard in the ІІ decade of December – 22.86 mg/100 g. The nitrate content of the plants did not exceed the maximum permissible concentrations for green plants, but exceeded the control by 17.4 mg/kg and 123.4 mg/kg. | ||
