The study was aimed to evaluate the sunnhemp genotypes suitable for green manuring. Fourteen sunnhemp genotypes were evaluated for morphological traits and it’s nutritional status during kharif-2021. The actual growth period for green manuring purpose was ranged between 65.00 and 68.00 days. The effective growth periods were 35.81 and 40.54, 38.44 and 41.74, 21.38 and 22.71 for plant height, number of branches per pant and number of leaves per plant, respectively. The genotypes, JRJ-610, SIN 28, SIN-37, SIN-44 and SUIN-053 were superior for green biomass production along with contributing characters (Plant height, number of branches or number of leaves). The genotypes, JRJ-610 and JRJ-25 for nitrogen content, SIN-37, JRJ-610 and SIN-21 for phosphorus content and SIN-25 and JRJ-610 for potassium content were promising for respective characters. The genotypes, SIN-25 and SIN-45 added maximum nitrogen, while, JRJ-610 and SIN-37 added maximum phosphorus and potassium content in soil. On the basis of overall performance, the genotype JRJ-610 and SIN-37attained maximum green manuring characters.
