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 wheat cv. Sana 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 (34,0 nodule/plant) was determined on the inoculated variant 2 as well as nodule dry weight (0,185 g/plant). Average yield of winter pea were ranging from 1827 kg ha-1 (control) up to 2558 kg ha-1 (inoculation). Average yield of winter wheat were ranging from 1803 kg ha-1 (control) up to 3084 kg ha-1 (nitrogen top-dressing). Average yield of winter peas in mixture wheat were ranging from 3630 kg ha-1 (control) up to 5330 kg ha-1 (nitrogen top-dressing). The highest number of pods (12,0) and of seeds per plant (48) was determined on the inoculated variant 2. The highest weight of 1000 seeds (114,5 g) and weight of seeds per plant (5,45 g) was determined on the inoculated variant 2.
