Impact of weather conditions and previous crops at post-harvest seeded soybean grain yield at OPG Vlado Neferanović

U radu su ispitivani utjecaji vremenskih prilika i agrotehnike na prinos i kvalitetu postrno sijane soje na OPG Vlado Neferanović tijekom 2020. godine. Korišteni su podaci sa Državnog hidrometeorološkog zavoda, meteorološke postaje Osijek i Gradište. Tijekom 2020. godine zabilježeno je 657,2 mm oborina, 67,2 mm manje u odnosu na višegodišnji prosjek (724,5 mm). Gledajući vegetacijsko razdoblje (od lipnja do listopada) u 2020. godini zabilježeno je 365,6 mm oborina, 37,5 mm više u odnosu na isto razdoblje u višegodišnjem prosjeku (328,1 mm). Prosječna temperatura 2020. iznosila je 13,2 °C, što je 0,7 °C toplije u odnosu na višegodišnji prosjek (12,5 °C). Gledajući vegetacijsko razdoblje (od lipnja do listopada), prosječna temperatura 2020. godine iznosila je 20,3°C, što je 0,9 °C toplije u odnosu na isto razdoblje u višegodišnjem prosjeku (19,4 °C). Agrotehnički zahvati na gospodarstvu odrađeni su po preporuci stručne literature, no prvenstveno po dosadašnjim iskustvima. Ostvaren je prosječni prinos od 2 t/ha za postrnu soju, što 2020. godinu čini vrlo dobrom za postrnu soju, iako su zabilježena odstupanja u temperaturi i oborinama u odnosu na višegodišnji prosjek.In this paper, weather conditions and agrotechnics and their influence on double cropped soybean yield at OPG Vlado Neferanović during 2020. were investigated. Data used in this paper was taken from the State's Hidrometeorological Institute, Osijek and Gradište stations. During the 2020. noted rainfall was 657,2 mm, 67,2 mm less than perennial average (724,5 mm). During the 2020. vegetation period (from June to October) noted rainfall was 365,6 mm, 37,5 mm more than the same period in perennial average (328,1 mm). Average temperature during 2020. was 13,2 °C, which is 0,7 °C warmer than the perennial average (12,5 °C). Average temperature during the 2020. vegetation period (from June to October) was 20,3 °C, which is 0,9 °C warmer than the same period in perennial average (19,4 °C). Agrotechnical work on farm was done according to professional literature, but primarily to previous experiences in soybean production. Average yield for the soybean was 2 t/ha what makes 2020. good year for soybean production, even though there were deviations in temperature and rainfall in regards to the perennial average
