Impact of weather condition on the yield and grain quality of two winter wheat cultivars in the 2018./2019. growing season on the Famili farm Ivica Jurić

Cilj istraživanja ovog diplomskog rada je bio prikazati uzgoj i tehnologiju proizvodnje pšenice na OPG-u Ivica Jurić u Nijemcima na području Vukovarsko-srijemske županije tijekom vegetacijske godine 2018./2019. te analizirati utjecaj vremenskih uvjeta na prinos i kvalitetu zrna dvije sorte pšenice, Ingenio i Falado. Za analizu vremenskih prilika korišteni su podaci Državnog hidrometeorološkog zavoda, a za prikaz tehnologije proizvodnje interni podaci OPG-a. Pšenica je ukupno uzgajana na 20 ha ili na 40 % površina gospodarstva. Obje sorte su posijane u optimalnom roku, a tijekom vegetacije primijenjena je adekvatna tehnologija uzgoja te je praćen rast i razvoj usjeva. Glavna karakteristika vegetacijskog razdoblja je nepravilna raspodjela oborina uz izrazito sušnu jesen i kišovito proljeće, dok su temperature zraka uglavnom bile više u usporedbi s referentnim višegodišnjim prosjekom, ali je svibanj bio vrlo kišovit i hladniji. Početno sušno razdoblje je dovelo do poteškoća prilikom osnovne i dopunske obrade tla te do usporenog početnog porasta i neujednačenog sklopa, ali je veća količina kiše u travnju poboljšala stanje usjeva. Unatoč specifičnim vremenskim uvjetima i nešto slabijoj gnojidbi, postignuti su zadovoljavajući prinos i kvaliteta zrna obje sorte. Prosječan prinos je iznosio 6,1 t/ha, hektolitarska masa je bila iznad 78 kg/hl, a sadržaj proteina 13,6 % kod sorte Ingenio te 13,9 % kod sorte Falado te su obje sorte svrstane u I. kvalitativnu klasu.The aim of this research was to present the cultivation technology of wheat production at the Family farm Ivica Jurić farm in Nijemci in the Vukovar-Srijem County during the 2018/2019 growing season and to analyze the impact of weather conditions on grain yield and quality of two wheat cultivars, Ingenio and Falado. The data of the State Hydrometeorological Institute were used for the analysis of weather conditions, and the internal data of the family farm were used to show the production technology. Wheat is grown on a 20 ha or 40% of the total area of the farm. Both cultivars were sown at the optimum term and adequate agrotechnics was applied during the growing season and the growth and development of the crop was monitored. The main characteristic of the vegetation period is the irregular distribution of rainfall with extremely dry autumn and rainy spring, while air temperatures were generally higher compared to the reference perennial average, but May have been very rainy and cooler. The initial drought period caused difficulties in basic and supplementary tillage, a slow early grow and crop density, but a greater amount of rain in April significantly improved the wheat condition. Despite specific weather conditions and slightly weaker fertilization, satisfactory grain yield and quality of both varieties were achieved. The average yield was 6.1 t/ha, the hectolitre mass was above 78 kg/hl, and the protein content was 13.6% for the Ingenio variety and 13.9% for the Falado variety, which means that both varieties were classified in the first qualitative class
