Effect of Combined Application of Composted Pressmud, Coirpith and Farmyard Manure on the Yield and Growth Characteristics of Green Gram (Vigna radiata L.)

A field experiment was carried out at Avinashilingam Institute for Home Science and Higher Education for Women, Coimbatore for assessing the effect of composted coirpith, composted pressmud, farmyard manure and NPK on vegetative and yield parameters of green gram (Vignaradiata L.). On 25^th day after sowing a significant increase in ischolar_main length in T₂(composted coirpith), shoot length in T₅(NPK 100%), number of leaves in T₇(composted pressmud+50%NPK), number of nodules inT₄(FYM), fresh weight inT₁₀(composted pressmud+25%NPK) and dry weight in T₁₁(FYM + 25%NPK) was noted. On 45thday an increase in ischolar_main length in T₁₀(composted pressmud+25%NPK),shoot length in T₆(composted coirpith + 50%NPK), number of leaves in T₃(composted pressmud ), number of nodules in T₄(FYM), number of flowers in T₈(FYM + 50%NPK), fresh weight in T₈(FYM + 50%NPK), dry weight in T₈(FYM + 50%NPK) was observed. On 55^th day a significant increase in ischolar_main length in T₅(NPK 100%), shoot length in T₃(composted pressmud), number of nodules in T₃(composted pressmud ), number of fruits in T₆ (composted coirpith + 50%NPK), fresh weight and dry weight in T₁₂(composted coirpith + composted pressmud + FYM) was observed. There was an increase in yield parameters number of pods/plant was increase in T₁₁(FYM +25%NPK), length of pods in T₁₀(composted pressmud + 25%NPK),weight of pods in T₁₀(composted pressmud+25%NPK), number of seeds / pod in T₅(NPK 100%), weight of seeds/pod in T₈(FYM + 50%NPK), pods fresh weight in T₁₀(composted pressmud +25%NPK) and pods dry weight in T₂(composted coirpith). The positive effect obtained from composted coirpith, composted pressmud and farmyard manure in this study favour the recycling of agrowastes for sustainable crop production.
