This research was to determine the correlations between grain yield and yield components and to measure the direct and indirect effects of yield components on grain yield of finger millet by using correlation coefficient and path analysis methods, respectively. The research was conducted in the 2013 and 2014 rainy seasons, at the research farm of the National Institute for Horticulture Bagauda, Kano in the Sudan savanna ecology of Nigeria. The treatment consisted of three seed rates (3, 6 and 9 kg ha-1), two sowing methods; broadcast and dibbling and poultry manure at 0, 2.5 and 5.0 t ha-1 and recommended NPK at (90:60:60 kg ha-1). The experiment was laid out in a split-plot design with three replications. The combination of sowing method and poultry manure including NPK were allocated to the main plot, while seed rate in subplot. Agronomic traits such as grain yield, plant height, leaf area index, number of tillers per plant, crop growth rate, panicle length, number of fingers per plant productive tiller per plant, 1000 grain weigh, straw yield ha-1, panicle yield ha-1 and weed parameters such as cumulative weed density and dry weight were determined. Correlation analysis indicated that the grain yield was positively and significantly associated with all the growth and yield characters evaluated but negatively correlated with the weed components. The highest correlation coefficients were found between grain yield and productive tillers per plant and between grain yield and harvest index. The partitioning of the total correlation into direct and indirect contribution showed that productive tillers per plant made greatest individual contribution to yield while productive tillers per plant via harvest index made the highest indirect percent contributions to grain yield of finger millet. Correlation and path analysis revealed that, productive tillers per plant and harvest index are the important yield contributing traits and due critical emphasis needs be given to these traits while selecting for grain yield improvement in finger millet
