A field experiment was conducted at College of Agriculture, Vellayani, Trivandrum to standardize the spacing and nutrient levels of fodder rice bean [Vigna umbellata (Thunb.)]. The treatments consisted of three spacings (S1 – 30 cm x 10 cm, S2 – 30 cm x 20 cm and S3 – 30 cm x 30 cm), three levels of nitrogen (N0 – 0 kg/ha, N1 – 20 kg/ha and N2 – 30 kg/ha) and three levels of phosphorous (P0 – 0 kg P2O5/ha, P1 – 20 kg P2O5/ha and P2 – 40 kg P2O5/ha). The highest protein content was observed when the lowest spacing 30 cm x 10 cm (S1) when the highest dose nitrogen was applied 30 kg/ha (N2). The lowest CF (16.43 %) was observed at S2 N0 P1. Spacing and N levels had significant impact on green fodder yield (GFY) and dry fodder yield (DFY). The highest GFY and DFY were produced at spacing of 30 cm x 10 cm (s1) and at N2 (30 kg N/ha) (while remaining at par with N1). The treatment S1 N2 P1 (30 cm x 10 cm spacing + 30 kg N/ha+20 kg P2O5/ha) recorded the highest GFY (17.29 t/ha) and DFY (3.46 t/ha).
