Abstract
Badania polowe przeprowadzono w latach 2016–2017 w uprawie jęczmienia jarego odmiany KWS Olof. Doświadczenia założono metodą split-plot. Celem badań było określenie działania trineksapaku etylu stosowanego na zróżnicowanych poziomach nawożenia azotowego. Trineksapak etylu stosowano solo w dawce 75 oraz 150 g/ha oraz w mieszaninach (75 g/ha) z siarczanem amonu oraz adiuwantem AS 500 SL na dwóch poziomach nawożenia (56 kg N/ha i 90 kg N/ha). Zwiększone nawożenie azotowe stymuluje wzrost rozkrzewień oraz plonowanie roślin w warunkach niedoboru opadów oraz zwiększa zawartość białka niezależnie od panujących warunków atmosferycznych. W wyniku zastosowania mieszanin trineksapaku etylu z siarczanem amonu lub z adiuwantem AS 500 SL uzyskano wzrost efektywności działania obniżonych dawek retardanta wzrostu. Sposób aplikacji mieszanin retaradanta nie miał istotnego wpływu na plon, obsadę, MTZ oraz parametry jakościowe ziarna w porównaniu do kontroli. The field experiment on spring barley cultivar KWS Olof were conducted in 2016 and 2017. The experiment was established using the split-plot method. Aim of the research was evaluation of trinexapac-ethyl applied at various levels of nitrogen fertilization. Trinexapac-ethyl was applied alone in two doses 150 g/ha and 75 g/ha and in a mixture of 75 g/ha with ammonium sulphate and the adjuvant AS 500 SL on two nitrogen fertilization levels (56 kg N/ha and 90 kg N/ha). Increased of nitrogen fertilization stimulated the tillering and the yield of plants in conditions of rainfall deficiency, and increased the protein content regardless the weather conditions. The addition of ammonium sulfate or AS 500 SL adjuvant to the spray liquid containing of trinexapac-ethyl improves reduced doses efficacy of grown retardant’s. The method of application of retaradant mixtures did not have a significant effect on the yield, density, mass of thousand grains and grain quality parameters as compared to the control.
