    Agrobiological evaluation of Allium ampeloprasum L. variety samples in comparison with Allium sativum L. cultivars
    (2019) Ulianych, O.; Yatsenko, V.; Didenko, I.; Vorobiova, N.; Kuhnyuk, O.; Lazariev, O.; Tretiakova, S.
    The purpose of investigation is to study the biological and morphological features, to establish the economic and valuable characteristics of the introduced and local forms of Allium ampeloprasum L. in comparison with Allium sativum L. and to study the effect of removal of the scape in the yield. The studies used field, statistical, settlement and analytical methods. The weight of the bulb without removing the inflorescence shoot of the cultivar Sofiivskyi was 28.4– 53.3 g smaller than the variety samples No. 2 and No. 3 respectively. With removing the scape the difference increased by 60.5–68.6 g. The yield of No. 2 variety sample Allium ampeloprasum L. without removing the scape was lower than the standard by 1.7 t ha-1 while the variety sample No. 3 exceeded the standard by 1.1 t ha-1 . With the removal of inflorescence shoot the yields of variety samples No. 2 and No. 3 exceeded the cultivar Sofiivskyi by 1.6 and 2.2 t ha-1 . It has been established according to the researches that introduced forms of Allium ampeloprasum L. have high indicators of economic and valuable characteristics, but they are limited in the first years of cultivation, by the period of adaptation to the new soil and climatic conditions.

    Effect of superabsorbent on soil moisture, productivity and some physiological and biochemical characteristics of basil
    (2021) Havrilyuk, M.; Fedorenko, V.; Ulianych, O.; Kucher, I.; Yatsenko, V.; Vorobiova, N.; Lazariev, O.
    The study was carried out in 2019–2020, in the conditions of the Right-Bank ForestSteppe of Ukraine. The results on the influence of absorbents in gel and powder forms on the productivity of basil plants (Ocimum basilicum L.) are presented. For research were used field, laboratory, statistical and calculation-analytical methods. Absorbent in the form of a gel was used while transplanting: dip the roots of the plant in the solution and then transplant in the field. Absorbent in the form of a powder - 5 kg ha-1 , application of the absorbent into the soil layer 20–25 cm-1 . Absorbents contributed to a slight decrease of sugar content (-0.86–2.68% in the cultivar of Badioryi, -1.48–2.35% in the cultivar of Rutan), significantly decrease ascorbic acid (-8.6–20.1%) and content of the essential oil (8.0–19.4%) and indirectly increased essential oil yield by increasing fresh weight yield in both varieties. The activity of APX, CAT, SOD, tended to decrease in all variants of the experiment, regardless of the form of the absorbent. APX (-12.8–35.1%), CAT (-10.9–22.0%), SOD (-11.9–17.0%). Higher yields were observed in the version with the introduction of the absorbent in the form of a gel. Thus, the yield of the cultivars of Badioryi and Rutan exceeded the control by 52.67 and 50.05%, in accordance. The productivity of basil is increased with the use of superabsorbent polymers. This practice can be recommended to agricultural producers who grow vegetables, in particular, basil in areas of unstable or insufficient moisture.

    Growth and yield of spinach depending on absorbents’ action
    (2020) Ulianych, O.; Kostetska, K.; Vorobiova, N.; Shchetyna, S.; Slobodyanyk, G.; Shevchuk, K.
    The use of absorbents from Maximarin for growing spinach contributed to its faster germination, increased plant growth and development, and resulted in an increase in yields of commodity products by 2.0–6.1 t ha-1 and an increase in chemical composition. The use of absorbents in open ground for spinach made it possible to obtain the highest amount of contingent net profit for making the drug Maximarin in the form of a gel and the company Eco – with small granules, and in the Krasen Polissia variety – 2,160 and 2,102 USD ha-1 , in the Malakhit variety for introduction the drug Maximarin in the form of a gel 1,949 USD ha-1 and the company Eco absorbent with potassium – 1,575 USD ha-1 . Profitability for the Matador variety has reached 75%, Malakhit grade – 69–75%, Keb – 3.0–3.2. It was established that in the closed ground application of the drug Maximarin in the form of gel and granules for spinach made it possible to obtain the highest amount of contingent net profit, which was Matador 3,079 and 3,025 USD ha-1 , in the Malakhit variety for the introduction of gel 4,304 USD ha-1 and granules – 4,245 USD ha-1 . Profitability for the use of drugs for the Krasenʹ Polissia variety reached 84–77%, Malakhit – 118–116 %, the bioenergy efficiency ratio – 3.0–3.3.
