摘要：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 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 (28 nodule/plant) was determined on the inoculated variant 2 as well as nodule dry weight (0,175 g/plant). Average pea seed yield were ranging from 1327 kg ha-1 (control) up to 1825 kg ha-1 (inoculation). Average triticale grain yield were ranging from 2375 kg ha-1 (control) up to 3345 kg ha-1 (nitrogen top-dressing). Average total grain yield of winter peas in mixture triticale were ranging from 3702 kg ha-1 (control) up to 5045 kg ha-1 (nitrogen top-dressing). This paper and given results are a humble contribution to the research of pea growth in the Republic of Croatia.
