In organic groundnut production, to improve use efficiency of organic nutrient sources and yield potential, the following study was formulated to study the effect of organic sources of nutrients on the growth, yield attributes and economics of groundnut field experiments were conducted during kharif seasons of three consecutive years (2009 to 2011) at Coconut Research Station, Tamil Nadu Agricultural University, Aliyarnagar, Tamil Nadu. The treatments were viz., farmers practice (control), Farm Yard Manure @ 7.5 t ha-1 inoculated with microbes (15 Days Before Sowing), seed treatments (Biofertilizers and Biofungicides) along with foliar spray of either 1 % Pseudomonas, 5 % Neem Seed Kernel Extract (NSKE) and 3 % of Panchagavya at 40-45 DAS in Randomized Block Design with three replications. The results revealed that application of FYM @ 7.5 t ha-1 inoculated with microbes (15 DBS) along with Seed treatment (Biofertilizers and Biofungicides) and Foliar spray of either 1 % Pseudomonas, 5 % NSKE and 3 % of Panchagavya at 40-45 DAS recorded the highest growth attributes, yield attributes and pod yield (2580 kg ha-1)
