Sažetak
Two year field trials (1999-2001) were carried out to determine the effect of seed winter pea inoculation and nitrogen top-dressing on number and nodule dry weight g /plant of pea root and also on the dry matter yield and fodder value of winter pea cv. Maksimirski ozimi and wheat cv. Sana mixture. Just before sowing the inoculation of pea seeds was performed by the indigenous variety of Rhizobium leguminosarum bv. viciae which is part of the microbial collection of the Department of Microbiology at the Faculty of Agriculture University of Zagreb. The highest total nodule number on pea root (34 nodule/plant) was determined on the inoculated variant variety of Rhizobium leguminosarum bv. viciae as well as nodule dry weight (0,185 g/plant). Total dry matter yields were ranging from 14,41 t ha-1 (control without inoculated seed of winter pea and nitrogen top-dressing) up to 17,04 t ha-1 (inoculated variety of Rhizobium leguminosarum bv. viciae). Yields of pea crude proteins in 2001 were ranging from 1781 kg ha-1 (nitrogen top-dressing 2 x 100 kg ha-1 27 % ammonium nitrate NH4NO3) up to 2269 kg ha-1 (inoculation) and in wheat, those values were from 902 kg ha-1 (control) up to 1270 kg ha-1 (nitrogen top-dressing). Total crude proteins mixture yields were from 2812 kg ha-1 (control) up to 3294 kg ha-1 (inoculation).
