Correlation and Path Coefficient Analysis for Some Yield-related Traits in Onion (Allium cepa L.)

U. Aliyu, M.D. Magaji , A.I. Yakubu and A.U. Dikko

Abstract:
The associations among growth and yield components and their direct and indirect influence on the bulb yield of onion were investigated. For this purpose, experiments were laid out which consisted of four levels of nitrogen (0, 50, 100 and 150 kg N ha-1), three levels of phosphorus (0, 17.5 and 35 kg P ha-1) and four intra-row spacing (10, 15, 20 and 25 cm), laid out in a split-plot design. Correlation and path coefficient analysis in onion showed that cured bulb yield had significant positive correlation with plant height, number of leaves per plant, bulb diameter and bulb weight but had negative association with percentage-culled bulbs. Path analysis indicated that bulb diameter, plant height and number of leaves per plant were the principal component of yield.
