Impact of weather conditions at winter wheat productivity at family farm Stjepan Klasnić in period 2011-2018

Cilj ovog rada je prikazati kako obrada tla i klimatske promjene utječu na proizvodnju pšenice na OPG Stjepan Klasnić. Sve agrotehničke mjere (obrada tla, sjetva, zaštita od korova, bolesti i štetnika), vremenske prilike ali i sorta pšenice (sortne osobine, njezin potencijal rodnosti) su imali značajan utjecaj na prinos i tehnološku kvalitetu zrna pšenice. Na temelju dobivenih financijskih rezultata može se zaključiti da je 2016. godina bila najbolja za proizvodnju ove kulture na OPG-u kao kombinacija visokog prinosa i povoljne otkupne cijene. Najlošiji financijski rezultat zabilježen je 2014. godine, gdje je niski prinos bio posljedica loših vremenskih prilika koje su dovele do povećanog napada bolesti ozime pšenice. Kompletni financijski rezultat iz svih godina pokazuje da je proizvodnja ove kulture na OPG-u profitabilna iako profit varira od 10.634 do 27.968 kn, ovisno o vremenskim prilikama, ali i o otkupnim cijenama.The aim of this final work is to show how tillage and climate change affect winter wheat production at the farm of Stjepan Klasnić. All agrotechnical measures (tillage, sowing, protection against weeds, diseases and pests), weather conditions and wheat variety (varietal traits, its fertility potential) had a significant impact on the yield and technological quality of wheat grain. Based on the financial results obtained, it can be concluded that 2016 was the best year to produce this crop at OPG as a combination of high yield and favorable purchase price. The worst financial result was recorded in 2014, where the low yield was the result of bad weather leading to an increased onset of winter wheat disease. The complete financial result from all the years shows that the production of this culture on the farm is profitable, although the profit varies from 10,634 to 27,968 kn, depending on the weather, but also on the purchase prices
