Abstract:
Laboratory experiment was conducted during 2019 at Anbil Dharmalingam Agricultural College and Research Institute, Thiruchirappalli to evaluate the allelopathic effect of Parthenium hysterophrous on germination and seedling growth of different field crops. Laboratory experiment was carried out in completely randomized design (CRD) with four replications and six treatments viz., control, 5, 10, 15, 20 and 25 % of P. hysterophorus whole plant extract. The results revealed that there was negative correlation observed between concentration of P. hysterophorus whole plant extract and germination percentage, seed length, root length, seedling length and seedling vigour index in all treatments. Increasing concentration of P. hysterophorus whole plant extract significantly inhibited the germination, shoot length, root length, seedling length and SVI of all tested crops. The highest seedling mortality percentage of various crops viz., sweet corn, groundnut, gingelly, cowpea and rice were registered at 25 % P. hysterophorus whole plant extract.
