THE IMPACT OF WEATHER CONDITIONS ON WINTER WHEAT GRAIN YIELD IN 2015./2016. YEAR ON FAMILY FARM “HERA“

Demonstracijski poljski pokus proveden je tijekom vegetacijske godine 2015./2016. Pokus dijelom financiran iz sredstava VIFZD 1030 od strane Poljoprivrednog fakulteta Osijek. Istraživanje je provedeno sa sortom ozime pšenice Renan na tri varijante obrade tla, i to varijante oranja, varijante tanjuranja i varijante izostavljene obrade tla, no-tillage-a. Veličina cijelog pokusa iznosila je cca 6 000 m2. Parametri koji su praćeni bili su komponente uroda i urod zrna ozime pšenice. Rezultati su komparativno uspoređeni. Vegetacijska godina 2015./2016. je bila izrazito nepovoljna u pogledu viškova oborina, i to posebno jesen 2014., a slično se nastavilo i 2015. godine. Cijelo istraživano vrijeme zabilježene su srednje mjesečne temperature veće od višegodišnjeg prosjeka. Razlike između istraživanih parametara nisu bile značajne, nego nam mogu poslužiti kao smjernice u daljnjoj poljoprivrednoj proizvodnji. U konačnici, na visinu uroda neminovno utječu vremensko/klimatske prilike, ali i primjenjena agrotehnika, odnosno njeni zahvati.Demonstration field experiment was conducted during the 2015/2016 crop year. The experiment partly funded by the VIFZD 1030 by the Faculty of Agriculture of Osijek. The study was conducted with a variety of winter wheat Renan three variants of tillage, and variants of plowing, disking variants and variants omitted tillage, no-tillage-a. Size of the whole experiment was approximately 6,000 m2. The parameters that were followed were the yield components and grain yield of winter wheat. Comparative results are compared. Vegetation year 2015./2016. was extremely unfavorable in terms of surplus rainfall, especially the fall of 2014., a similar continued and 2015. All the studied time recorded average monthly temperatures are higher than long-term averages. Differences between the studied parameters were not significant, but can serve as guidelines in further agricultural production. Finally, at the height of yield inevitably affect weather / climate conditions, and applied agricultural technology, and its procedures
