Efekat različitih doza prihrane na prinos i neke osobine durum pšenice

Abstract

U radu su prikazani rezultati jednogodišnjeg ogleda durum pšenice, koji je sproveden u Starom Ţedniku, tokom 2016/17. godine. Cilj istraţivanja bio je da se uporedi uticaj različitih doza prihrane azotom na prinos i neke morfološke osobine durum pšenice. Ogled je izveden na tri podparcele, gde je na svakoj primenjena različita količina mineralnog đubriva (40 kg N ha-1; 65 kg N ha-1; 120 kg N ha-1). Na parceli gde je primenjena najmanja količina azota, postignut je najbolji prinos i najveća visina biljke. Najlošije biljke su bile na paraceli gde je primenjen srednji nivo prihrane. Najveći nivo prihrane, nije dao opravdane rezultate. Na osnovu dobijenih rezultata ustanovljeno je da su na parceli gde je primenjena najniţa količina prihrane, u proseku dobijeni najbolji rezultati, dok su najniţe vrednosti zabeležene kod srednje doze prihrane, to je rezultat smanjenih količina padavina, pa je efekat primenjenih mineralnih hraniva izostao.

The paper presents results of a one-year experiment on durum wheat, performed in Stari Zednik in 2016/17. The aim of the research was to compare the influence of various doses of nitrogen fertilizer on yield and certain morphological properties of durum wheat. The experiment was carried out on three plots, where different amounts of mineral fertilizers were applied (40 kg N ha-1, 65 kg N ha-1, 120 kg N ha-1). The plot where the lowest amount of nitrogen was applied had the best yield and tallest plants. The worst plants were on the plot where mid-level fertilization was applied. The highest level of fertilization was not justified by the results. Based on obtained results, it was established that on the average the best result was obtained on the plot where the lowest amount of fertilizer was applied, while the lowest values were recorded with the mid-level dose, which resulted from reduced precipitation, so that the effect of the applied mineral fertilizer was not realized.
