    Influence of Variety, Elements of the Fertilization System, Sowing Rates of Seeds on the Pea Yield (Pisum sativum)
    (Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2020) Lykhochvor, Volodymyr; Andrushko, Mykola; Andrushko, Oleg; Lviv National Agrarian University, Dubliany, Ukraine
    The yield of pea varieties depending on the elements of the fertilizer system and sowing rates. In the first experiment, nine variants of the application of mineral fertilizers on the variety ‘Madonna’ were studied: 1. P0K0 – control; 2. P0K0 + Optimize Pulse; 3. P60K60; 4. P60K60 + N60; 5. P60K60 + S30; 6. P60K60 + N60 + S30; 7. P60K60 + Mg20 + S30; 8. P60K60 + N60 + + Mg20 + S30; 9. P60K60 + N60 + Mg20 + S30 + Intermag beans (2 l/ha). In the second experiment, three varieties of ‘Madonna’, ‘Gotivsky’, and ‘Otaman’ were studied with six sowing rates of 0.9, 1.0, 1.1, 1,2, 1.3, 1.4 mln/ha.As a result of studies, it was found that the highest yield of pea grain was obtained in the ‘Madonna’ variety – 6.38 t/ha. As to the ‘Gotivsky’ variety the yield is lower and amounted 6.13 t/ha, which is by 0.25 t/ha less than the ‘Madonna’ variety. The lowest grain yield was in the ‘Otaman’ variety – 5.94 t/ha, which is by 0.44 t/ha less than the ‘Madonna’ variety and by 0.19 t/ha compared to the ‘Gotivsky’ variety.The highest yield of ‘Madonna’ pea grains (6.43 t/ha) was formed during the application of mineral fertilizers according to the following scheme: P60K60 + N60 + Mg20 + S30 + Intermagus beans (2 l/ha). Due to the improvement of the pea nutrition system, the yield increased by 2.43 t/ha or 60.7% compared to the control (P0K0). It has been investigated that the optimal sowing rate of the ‘Madonna’ pea variety is 1, 0 and 1.1 mln./ha, for the ‘Gotivsky’ variety –1.2 mln/ha and as to the ‘Otaman’ variety – 1.1 and 1.2 mln/ha. Improvement of elements of cultivation technology for conditions of sufficient moistening of the western forest-steppe of Ukraine allows to obtain stable yield of pea grain at the level of 6–7 t/ha.
