Correlation and Path Coefficient Analysis in Ashwagandha (Withania somnlfera Dunal)

摘要

An experiment on correlation and path coefficient analysis in ashwagandha was conducted at Agricultural Research Station, Annigeri (Karnataka) during early Rabiseason of 2004 and 2005 under rainfed conditions. The results on correlation coefficients indicated that the harvest index exhibited the highly significant and positive correlation with dry root yield per plant followed by plant height and dry matter per plant. While the highest direct and positive effect on dry root yield per plant was observed with harvest index followed by dry matter per plant, LAI and plant height. The root length showed the highest negative direct effect on dry root yield per plant.
