A field experiment was conducted to study the influence of chemical input module vs. organic farming modules on growth, yield and economics of summer groundnut under organic farming at the Agronomy Instructional Farm, C. P. College of Agriculture, S. D. Agricultural University, Sardarkrushinagar during summer seasons of 2014 and 2015. The experiment was conducted with two organic farming modules viz; OFM-I and OFM-II and chemical input module (CIM). Among the different modules under testing, organic input packages module II (OFM-II) which consists soil application of 25 kg N/ha through FYM + Trichoderma harzianum @ 1.5 kg/ha + seed inoculation with Rhizobium and PSB @ 30 g/kg seed, along with installation of 50 bird perches and 8 pheromone traps/ha + spray of neem based product @ 30 ml/10 lit of water when Helicoverpa armigera larval population exceeds 5 larvae/m row length + spraying of HaNPV @ 450 LE/ha in 500 lit water + spraying of Spinosad @ 75 g a.i./ha when Helicoverpa population exceeds 5 larvae / meter row resulted in drastic improvement of growth and yield attributes, pod and haulm yields and net returns of summer groundnut closely followed by organic farming module I (OFM- I) as compared to chemical input module (CIM).
