An experiment entitled Productivity dyanamics of groundnut as influenced by different plant densities and fertilizer levels during summer season was carried out during summer season of 2015 at the farm of Oilseed Research Unit, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola (M.S.). The treatments comprised of three spacing 30 x 10 cm, 25 x 10 cm and 20 x 10 cm and three fertilizer levels 75%, 100% and 125% RDF ha-1. The experiment was laid out in a factorial randomized block design (FRBD) with three replications. Among three spacing, 30 x 10 cm was superior over 20 x 10 cm in respect of plant height (cm), number of branches plant-1, plant spread (cm), number of root nodules plant-1,dry matter accumulation plant-1 (g), haulm yield (kg ha-1). Treatment 20 x 10 cm was superior over 30 x 10 cm in respect to pod yield (3038 Kg ha-1), biological yield (6993 kg ha-1) and Harvest index (42.50%). The growth and yield attributes showed significantly increased when use of 125 % RDF ha-1. Pod yield (2809 Kg ha-1), haulm yield (4248 Kg ha-1) obtained was significantly higher at application of 125 % RDF ha-1 than 75 % and 100 % RDF ha-1. Use of 125% RDF ha-1 was found to most economical than 75 % and 100 % RDF.
