Sažetak
Two year field trials (1999-2001) were aimed to determine the inoculation seed winter pea and nitrogen top-dressing effect on number and active nodules of pea root and also on the green mass and dry matter yield of winter pea cv. Maksimirski ozimi and triticale cv. Clercal mixture. Immediately before sowing the inoculation of pea seeds was done by the indigenous variety of Rhizobium leguminosarum bv. viciae which belongs to the collection of Department of Microbiology at the Faculty of Agriculture University of Zagreb. The highest total nodule number on pea root (134) was determined on the inoculated variant as well as active nodule (120). Average mixture green mass yields were ranging from 20.9 t ha-1 (control) up to 30.1 t ha-1 (inoculation + nitrogen top-dressing). Total dry matter yields were ranging from 3.71 t ha-1 (control) up to 5.36 t ha-1 (nitrogen top-dressing). Pea crude protein yields in 2001 were ranging from 500 kg ha-1 (nitrogen top-dressing) up to 642 kg ha-1 (inoculation) and for triticale, those values were from 322 kg ha-1 (control) up to 498 kg ha-1 (nitrogen top-dressing). Total mixture crude proteins yields were from 845 kg ha-1 (control) up to 998 kg ha-1 (nitrogen top-dressing).
