Abstract: A field experiment was conducted at the instructional farm by All India Co-ordinated Research Network on Potential crops project under Odisha University of Agriculture and Technology, Bhubaneswar during kharif season of 2016 to study the response of promising rice bean (Vigna umbellata) (Thunb.) Ohwi & Ohashi [Fabaceae] genotypes in different levels of nitrogen in a sandy loam soil with pH 5.46, available nitrogen 230 kg/ha, available phosphorus 30.8 kg/ha (Bray’s Method) and available potash 180.3 kg/ha. The treatment combination were six varieties in the main plot (RBL01, RBL06, RBL35, Phulbani Local, BRB05, BRBM102) and four levels of nitrogen (0, 20, 40 and 60 kg N.ha-1) in the sub-plot, They were tested in a split plot design with three replications.
The variety BRBM 102 recorded highest seed yield (790.08 kg-1) followed by Phulbani Local (785.4 kg.ha-1). Application of successive doses of nitrogen up to 40 kg/ha produced maximum seed yield of 865.06kg.ha-1 and stover yield of 2231.6 kg.ha-1.Seed yield increased by 20.7, 39.7 and 49.6% with application of 40 kg N.ha-1 over 20, 60 and 0 kg N/ha respectively. The Variety BRBM102 recorded maximum value in plant height of 111. 81cm,number of branches per plant (3.4), dry matter accumulation per plant(15.47g), root length (29.57cm), number of nodules per plant (15.33) and yield attributing characters like more number clusters per plant (17.18), pods per plant (61.38) and number of seeds per plant (8.00).Irrespective of varieties application of 40 kg Nha-1 favorably influenced the growth, yield and yield attributes
