Maize productio on agricultural surface on agricultural holding Grube during two years

Osnovni cilj rada bila je analiza proizvodnje odnosno provedene agrotehnike kukuruza na PG Grube d.o.o. tijekom dva vegetacijska razdoblja 2016 i 2017. Poljoprivredno gospodarstvo obrađuje oko 350 ha oranica na kojima dominira proizvodnja kukuruza, a bavi se i stočarskom proizvodnjom. Analizirane godine su bile drugačije sa stajališta uzgoja kukuruza jer je u 2016. bilo više, a 2017. manje oborina od promatranog prosjeka (1981.-2016.). Istovremeno, temperature zraka su bile više u obje godine. S obzirom da PG Grube posjeduje vrlo velik broj suvremene mehanizacije sve agrotehničke operacije su provedene u skladu s pravilima struke ukoliko su to vremenske prilike dozvoljavale. Sjetva kukuruza se obavila na gustoću sklopa od 64 000 do 69 000 biljaka po ha, a posijani su hibridi sjemenskih kuća Bc Instituta Zagreb i KWS. S obzirom da je kukuruz širokoredni usjev posebna pozornost se posvetila zaštiti protiv korova. Na PG Grube ostvareni prinosi kukuruza su jako ovisili o vremenskim prilikama tijekom vegetacije, ali općenito bili su iznadprosječni u usporedbi s državnim prosjekom. Ostvareni prinosi u 2016. su se kretali od 11,9 t/ha do 15,6 t/ha, a u 2017. su iznosili od 6,8 t/ha do 12,5 t/ha.The main aim of the work was to analyse the production of the maize and agrotechnics at PG Grube d.o.o. during the two vegetation periods 2016 and 2017. On this farm about 350 hectares is cultivated and maize production dominates, but is also engaged in livestock production. The analysed years were different from the standpoint of maize growing because in 2016 there were more, and in 2017 was less precipitation than the observed average (1981-2016). At the same time, air temperatures were higher in both years. As PG Grube possesses a very large number of modern mechanics, all agrotechnical operations have been carried out in accordance with the rules of the profession, if permitted by weather conditions. Maize sowing was done on a density of 64,000 to 69,000 plants per ha, and maize hybrids of Bc Institute Zagreb and KWS were sown. Special attention has been paid to the protection against weeds. Maize yields on PG Grube were highly dependent on weather conditions during vegetation but overall were above average compared to the state average. The realized yields in 2016 ranged from 11.9 t/ha to 15.6 t/ha, and in 2017 from 6.8 t/ha to 12.5 t/ha
