| Abstract | As for today for the development of the agricultural sector of the economy on purpose of obtain a high yield of spinach, it is necessary to use highly productive varieties. Innovative varieties should be introduced, taking into consideration the adaptive capabilities of the variety to the soil and climatic conditions of growing. The article is presented a comparative assessment of the productivity and adaptive capacity of the spinach varieties in purpose of obtain highly productive crops in the conditions of the Steppe of Ukraine. The continuance of the phenological phases of the plants was studied. The phenological observations of the plants of the different varieties of the spinach showed that they developed differently depending on the biological properties of the variety. The observations of the growth and development of the plants and biometric indicators was conducted in dependence on the biological characteristics of the variety. It was proved that plants of the spinach varieties were different in height, number of leaves, leaf surface and their total surface per hectare, which, compared with the control, were higher due to use of the best variety. The plants height before harvesting was higher in the varieties of spinach Matador, Malachite and Krasen Polissia – 6,0 ± 0,05 – 6,3 ± 0,03 cm, respectively. The plants of the varieties Matador, Malachite, Krasen Polissya and Peremozhets were higher before harvesting – 22,3 ± 0,22 – 25,2 ± 0,20 cm. The leaves surface of the spinach before harvesting at control was 12,3 ± 0,02 thousand sq.m per ha. It was higher due to varieties Malachite, Peremozhets and Krasen Polissya – 15,3 ± 0,02 – 15,4 ± 0,03 thousand sq.m per ha. The productivity and yield level of the variety have been determined. On average, during the research period variety Malachite provided a high yield. It provided 22,1 t/ha of the marketable green leaves, which exceeds the control by 5,7 t/ha. Control showed low yield – 16,4 t/ha. Matador and Fantasy showed high yield as well – 20,8 t/ha. They significantly over control at 4,4 t/ha. Thus, the cultivation of new varieties of the spinach made it possible to additionally receive from 4,0 t/ha to 5,7 t/ha of the green leaves | ||
