Abstract
Istraživanje uzgoja heljde tijekom vegetacijskog perioda pojave korova je provedeno na dvije lokacije s različitim datumima sjetve, u razmaku od dva tjedna. Na svakoj lokaciji promatrala su se dva sustava proizvodnje: konsocijacija heljda/orah i oranica tj. kontrolna parcela heljde bez oraha. Tijekom vegetacije odredila se suha tvar po jedinici površine, prinos, gustoća sklopa te zakorovljenost. Determinirani su dominantni korovi. Ranija sjetva u Đakovu imala je više prinose na oranici tj. kontrolnoj parceli bez oraha dok unutar konsocijacije nije bilo razlike u prinosu heljde između Đakova i Ivankova. No rezultati su pokazali da postoji statistički značajna razlika između ranijeg i kasnijeg datuma sjetve u iznosu suhe tvari po hektaru unutar konsocijacije orah/heljda. Kasnije zasijana heljda u Ivankovu imala je statistički značajno veću biomasu unutar kosocijacije. Na kontrolnim parcelama nije bilo statistički značajne razlike u biomasi između dva lokaliteta. U Đakovu, parcela kontrole je bila manje zakorovljena od parcele oraha. Pojava ambrozije je bila jednaka na svim promatranim parcelama iako u Ivankovu, gdje je bila kasnija sjetva, i ambrozija se pojavila kasnije.
Abstract (english)
Research was conducted during vegetation period on two locations with different sowing dates, at two weeks intervals. At each location two systems were observed: buckwheat/walnut and ploughland, ie. buckwheat field without walnut. During vegetation, dry matter per area unit, yield, plant assembly density, and weeds were determined. The dominant weeds were determined. The results showed that earlier sowing in Đakovo had higher yields on arable land, ie. control plot without nuts, while within the consociation there was no difference in buckwheat yield between đakovo and Ivankovo. The result showed there was a statistically significant difference between the earlier and later sowing date in the amount of dry matter per acre within the walnut/buckwheat consociation. Buckwheat sown later in Ivankovo had statistically significant higher biomass within consociation. In the control plots, there was no statistically significant difference in biomass between the two sites. In Đakovo, control plot had less weeds than buckwheat/walnut plot. Common ragweed appeared on all observed plots, altough in Ivankovo, where buckwheat was sown later, ragweed appeared later.
