Fourty four genotypes of groundnut were used to study the correlation and path analysis for yield, quality and their contributing characters under two fertilizer managements viz., organic and conventional. Correlation analysis revealed that kernel yield per plant was significantly and positively correlated with days to 50 % flowering, primary branches per plant, total number of pods per plant, number of mature pods per plant, pod yield per plant, harvest index, 100 seed weight and protein content under both the managements. When both direct and indirect positive contributions were considered, pod yield per plant and shelling percentage influenced kernel yield per plant under both managements signifying the importance of these traits in the improvement of kernel yield.
