Effects of Rhizobium Inoculant, Compost, and Nitrogen on Nodulation, Growth, and Yield of Pea

The effects of Rhizobium inoculant, compost, and nitrogen on nodulation, growth, dry matter production, yield attributes, and yield of pea (Pisum sativums var, IPSA Motorshuti-3 were assessed by a field experiment. Among the treatments Rhizobium inoculant alone performed best in recording number and dry weight of nodules/plant. The highest green seed yield of 8.38 ton/㏊ (36.9% increase over control) and mature seed yield of 2.97 ton/㏊ (73.7% increase over control) were obtained by the application of 90 ㎏ N/ha. The effects of 60 ㎏ N/㏊, Rhizobium inoculant alone and Rhizobium inoculant along with 5 ton compost/㏊ were same as the effect of 90 ㎏ N/㏊ in recording plant height, root length, dry weight of shoot, and root both at preflowering and pod filling stages, number of mature pods/plant, number of mature seeds/pod, 1000-seed weight, green, and mature seed yields of pea.
