Soybean, Glycine max L. Merrill is one of the most important protein sources for human and livestock all over the world. The world's population is constantly increasing; therefore the increase in crop production per area is very important. For obtaining high yields, nowadays, in agriculture, mineral fertilizer is often used amendments as zeolite in purpose of a sustainable agriculture. The paper presents results obtained in the 2013-2014 years experimental the variety Felix the production and protein content from soybean seeds. The highest soybean production was obtained in climatic condition in the 2014 experimental year in all the treatments in comparison with the 2013 year. Significant soybean production values in 2014 year were obtained for the treatments with 50 kg/ha urea+50 kg/ha zeolite (V4); 70 kg/ha urea+30 kg/ha zeolite (V5);–50 kg/ha NP20:20+50 kg/ha zeolite (V6) compared with the treatment only with zeolite application as amendment. Significant soybean protein values in 2013 year were obtained for the treatments with 50 kg/ha urea+50 kg/ha zeolite (V4); 70 kg/ha urea+30 kg/ha zeolite (V5);–50 kg/ha NP20:20+50 kg/ha zeolite (V6) compared with the treatment only with zeolite application as amendment. Zeolite amendments from 2014 year cause no significant difference on the protein content of the seeds, in comparison with the other treatments.
