Field experiment was conducted at Coconut Research Station, Aliyarnagar during Rabi/Summer for three consecutive yearsto maximize yield of groundnut through integrated nutrient approach and rescheduling fertilizer levels along with farmyard manure and to study the impact of split application of fertilizers along with economic feasibility of integrated nutrient combinations. The experiment was laid out in Randomized Block Design with three replications and ten treatments,T1: RDF (100%) as basal, T2: RDF (100 %) as basal + FYM @ 7.5 t ha-1, T3: RDF (75 %) as basal + RDF (25 %) as top dressing at 30 DAS, T4: RDF (75 %) as basal + RDF (25 %) as top dressing at 30 DAS + FYM @ 7.5 t ha-1, T5: RDF (150%) as basal, T6: RDF (150 %) as basal + FYM @ 7.5 t ha-1, T7: RDF (100 %) as basal + RDF (50 %) as top dressing at 30 DAS, T8:RDF (100 %) as basal + RDF (50 %) as top dressing at 30 DAS + FYM @ 7.5 t ha-1, T9:RDF (75 %) as basal + RDF (75 %) as top dressing at 30 DAS, T10: RDF (75 %) as basal + RDF (75 %) as top dressing at 30 DAS + FYM @ 7.5 t ha-1. Gypsum @ of 400 kgha-1 was applied as basal. were applied to the recommended dose of fertilizers. Results revealed that application of recommended dose of fertilizers (RDF) (100%) as basal + RDF (50 %) as top dressing at 30 DAS + FYM @ 7.5 tha-1 recorded higher pod yield and net returns (2936 kgha-1 and Rs. 91789ha-1, respectively) and were comparable with RDF (75 %) as basal + RDF (75 %) as top dressing at 30 DAS along with 7.5 tha-1 of FYM higher pod yield and net returns (2812 kgha-1 and Rs. 86610ha-1, respectively). Economic analysis registered that RDF (100 %) as basal + RDF (50 %) as top dressing at 30 DAS along with 7.5 tha-1 of FYM recorded the maximum return of Rs. 91789 and BCR of 3.10 and was closely followed by RDF (75 %) as basal + RDF (75 %) as top dressing at 30 DAS with a maximum return of Rs. 86610 but with a BCR of 3.05 the additional cost of FYM were not incurred in cost of cultivation.
