Abstract
The field experiments with spring barley cultivar KWS Olof were conducted in 2013–2014. The tested products (Cerone 480 SL), adjuvants (Slippa, Atpolan 80 EC) and fertilizers (ammonium sulfate, urea) and some of their mixtures were applied on spring barley at the stage of BBCH 35. The higher effectiveness of shortening stems of spring barley was obtained after the use of Cerone 480 SL at the dose of 0.75 l/ha as compared to the control. The reduction of spring barley stem length was dependent of spray liquid compounds and it was 9.7–13.0% (2013) and 2.6–11.0% (2014) in the years of investigation, respectively. The addition of adjuvants Slippa or ammonium sulfate to the spray liquid containing ethephon improved efficacy of grown retardants. The method of application of ethephon did not have any influence on yield of spring barley and some parameters of yield component. However the usage of full or reduced doses of ethephon caused a non-significant decrease the thousand grain weight compared to the untreated plots. In both years of the study no phytotoxicity effect of the examined mixture was observed on spring barley cultivar KWS Olof. Doświadczenia polowe prowadzono w uprawie jęczmienia jarego odmiany KWS Olof w latach 2013–2014. Badane preparaty (Cerone 480 SL), adiuwanty (Slippa, Atpolan 80 EC), nawozy (siarczan amonu, mocznik) oraz ich wybrane mieszaniny zastosowano w fazie strzelania w źdźbło (BBCH 35) jęczmienia jarego. W obydwu latach badań największe skrócenie długości źdźbeł w porównaniu do nietraktowanej kontroli uzyskano po zastosowaniu retardantu Cerone 480 SL w dawce 0,75 l/ha. Efektywność działania obniżonej dawki etefonu uzależniona była od składu mieszaniny i wynosiła w zależności od roku badań 9,7–13,0% (2013) i 2,6–11,0% (2014) skrócenia źdźbeł. Dodatek adiuwantu Slippa lub siarczanu amonu do cieczy opryskowej zawierającej etefon wpłynął na poprawienie efektywności działania retardantu wzrostu. Sposób stosowania etefonu nie miał istotnego wpływu na wybrane parametry struktury plonu. Natomiast zastosowanie etefonu w pełnej lub obniżonej dawce przyczyniło się do nieistotnego obniżenia masy tysiąca ziaren w porównaniu do kontroli. W obydwu latach badań nie stwierdzono fitotoksycznego oddziaływania badanych mieszanin na jęczmień jary odmiany KWS Olof.
