Abstract: Keeping the importance of screening of associated factors for improved seed germination, an experiment was undertaken with 25 germplasm of Kalmegh at BAU, Kanke to study its seed germination behavior suited for the climatic and edaphic conditions of Jharkhand. Correlation matrix between seed germination parameters of Kalmegh seeds under field condition indicated that the germination energy had highly significantly positively correlation with germination percentage (0.939) and seedling vigour index (0.914). Similarly, germination percentage had highly significantly correlation with seedling vigour index (0.970). Multiple regression analysis of germination parameters indicated that germination period, rate of germination, germination percentage, shoot as well as root length of seedlings and root-shoot ratio affect seedling vigour index of Kalmegh significantly. Path analysis of characters influencing seedling vigour index of Kalmegh seedlings under field conditions showed that eight parameters had direct positive effect on seedling vigour index, in which maximum direct effect was observed by germination percentage (0.716). Three parameters showed direct negative effect on seedling vigour index, in which maximum impact was shown by days taken for complete of seed germination (-0.235). From the findings, it can be inferred that for higher seedling vigour index, rate of germination, germination percentage, shoot as well as root length of seedlings and root-shoot ratio of seedlings should be selected as important parameters as their higher values gave higher seedling vigour index.
