A field experiment was conducted during pre- kharif seasons of 2008-09 to study the effect of organics on yield and quality of groundnut ( Arachis hypogaea L.) under terai region of West Bengal. The experiment was laid out in randomized block design with 12 treatments and replicated thrice. Results revealed that poultry manure 2.5 t/ha + neem cake 2.5 t/ha + vermicompost 2.5 t/ha + phosphocompost 2.5 t/ha gave 2.08 tonne pod yield/ha, which was 9.47% higher over recommended dose of chemical fertilizer. Combined application of vermicompost 2.5 t/ha + phosphocompost 2.5 t/ha + poultry manure 2.5 t/ha + neem cake 2.5 t/ha brought about significant improvement in N, P and K uptake by groundnut. Application of organic manures resulted in the improvement of soil organic car- bon, available soil N, P and K compared to either recommended dose of fertilizers or control. Among the organic treatments, phosphocompost 5 t/ha recorded highest values of oil (46.7%), crude protein (22.4%), soluble protein (10.5%), total sugar (13.1%), starch (14.8 %), calcium (143.92 mg/100g) and phosphorus (836.6 mg/100g) dur- ing both the years.References
