Abstract
Soja (Glycine max (L.) Merr) je jednogodišnja leguminozna biljka. Pripada porodici Fabaceae. Soja se u svetu gaji na oko 117 mil. ha i zauzima vodeće mesto među proteinsko-uljanim kulturama. Ogled sa sojom izveden je na pseudogleju. Istraživanja su obavljena sa ciljem da se ispita uticaj đubrenja azotom na masu nodula i sadržaj azota u nodulama soje, na lokalitetu Brezovo Polje u Brčkom, na zemljištu tipa pseudoglej. Primenje su četiri varijante N đubrenja: 1.) 0 kg/ha, kontrola; 2.) 50 kg/ha; 3.) 100 kg/ha i 4.) 150 kg/ha. Najveća masa nodula bila je u kontrolnoj varijanti dok je u varijanti sa najvećom količinom hraniva bila najmanja masa nodula. Najveći sadržaj azota u nodulama bio je u varijanti sa primenom 50 kg ha-1 i iznosio je 4,93 %, dok je najmanji sadržaj azota u nodulama bio u kontrolnoj varijanti. Pozitivna nesignifikantna korelaciona veza ostvarena je između mase nodula i sadržaja azota u nodulama (r=0,19).
Soybean (Glycine max (L.) Merr) is an annual legume plant. It belongs to the family Fabaceae. Soybeans are grown in the world at around 117 million ha and occupies a leading position among the protein-oil crops. The experiment was carried out with soybean on pseudogley. The trial was conducted in order to investigate the effect of nitrogen fertilization on the mass of nodules and nitrogen content in soybean nodules at the site of Brezovo Polje in Brčko, on pseudogley. Applied four variants nitrogen fertilization: 1) 0 kg ha-1, control; 2) 50 kg ha-1; 3) 100 kg ha-1, and 4) 150 kg ha-1. Maximum mass of nodules was in control variant and the variant with the highest amount of nutrients the minimum weight of nodules. The highest content of nitrogen in nodules was in the variant with the application of 50 kg ha-1 and amounted to 4.93%, while the lowest content of nitrogen in nodules was in control variant. Positive non-significant correlation was achieved between the weight of nodule...s and nitrogen content in nodules (r = 0.19).
