A field experiment was conducted at Agricultural Research Station, Banswara (Raj.) during rainy season of 2012-14 to evaluate the response of organic plant nutrient sources on productivity and profitability of groundnut and soil fertility status. The experiment consisted of 12 treatment combinations of FYM, vermicompost, neem cake, bone meal, poultry manure, rock phosphate, green manuring, residue mulching and BD500 laid out in randomized block with three replications. Results revealed that combined application of FYM+ rock phosphate + gypsum + biofertilizers + BD 500 (T11) produced higher plant height (79.33cm), pods (42.0 plant-1), kernels (2.02 pod-1), test weight of kernels (347g), pod yield (45.17q ha-1), kernel yield (34.48q ha-1), haulm yield (7633kg ha-1), and shelling (73.22%) followed by T6 –T10 in the case of plant height, kernel test weight, haulm yield and shelling per cent and T7-T10 in case of pod, kernel yield,T8-T10 in case of pods plant-1, T10 in case of kernels plant-1 and found significantly superior over rest treatments, respectively. The maximum gross return (Rs.134388 ha-1) and net return (Rs 109568 ha-1) and B:C ratio (4.41) recorded higher in combined use of FYM+ rock phosphate+gypsum+biofertilizers+BD500 (T11) and found significantly higher over rest treatments. Maximum organic carbon (0.89%) recorded in T10 followed by T7-T9 andT11 and significantly higher over rest treatments. The maximum available N (292.40kg ha-1) recorded in T9 followed by T8, T10 and T11 and significantly higher over rest treatments. The maximum available phosphorus (39.20kg ha-1) was recorded in T11 followed by T7-T10 and T5 and significantly higher over rest treatments. The higher available potassium was recorded in T10 followed by T7-T9 and T11 and significantly higher over rest treatments. On the based on finding combined application of organic plant nutrient resources were resulted better than a single application.
