Abstract
Two year field trials (1999-2001) were carried out to determin 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 yield of winter pea cv. Maksimirski ozimi and triticale cv. Clercal mixture. Just before sowing the inoculation of pea seeds was performed by the 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 (30 nodule/plant) was determined on the inoculated variant 2 as well as nodule dry weight (0,150 g/plant). Average pea seed yield were ranging from 1205 kg ha-1 (control) up to 1836 kg ha-1 (inoculation). Average triricale grain yield were ranging from 2469 kg ha-1 (control) up to 3753 kg ha-1 (nitrogen top-dressing). Average total grain yield of winter peas in mixture triticale were ranging from 3674 kg ha-1 (control) up to 5321 kg ha-1 (nitrogen top-dressing). The highest number of pods (9,5) and of seeds per winter pea plant (38,5) was determined on the inoculated variant 2. The highest on thousand seeds weight (104,5 g) and weight of seeds per winter pea plant (4,03 g) was determined on the inoculated variant 2.
