Association analysis was studied in twenty F1 crosses and five parents of barnyard millet to find out the association of nutrient characters and their direct and indirect effects on single plant yield. The results exhibited that the nutrient traits are inter-related and improvement of yield will bring about the simultaneous improvement of the nutrient characters also. Total phenols and iron content recorded moderate positive direct effects on single plant yield. Total anti-oxidant activity and zinc content had low negative direct effects on single plant yield that were neutralized by positive indirect effects of other traits. The analysis revealed that the improvement of yield will simultaneously bring improvement on total phenols and iron content directly and on total anti-oxidant activity and zinc content indirectly.
