Correlation and path coefficient analysis of bulb yield components in garlic (Allium sativum.L)

Abstract

Field studies were carried out at Usmanu Danfodiyo University Teaching and Research Fadama Farm Kwalkwalawa, Sokoto, during the 2002/2003 and 2003/2004 dry seasons to investigate the relationship between bulb yield and some growth and yield characters with a view to identifying those characters that could be used in improving bulb yield potential of garlic. The experiment was laid out in a split- plot design with three replications. Growth as well as yield correlation coefficient analyses revealed that virtually all the growth and yield components have indicated interdependency, owing to positive and significant correlation observed amongst nearly all the parameters. Path coefficient analysis showed that yield components made their optimum contribution through bulb weight, clove weight and number of cloves per bulb
