Abstract
Lucerne or alfalfa (Medicago sativa L.) vernacularly called ‘Rijka’ is one of the important fodder crop of family Leguminoseae and genus Medicago grown on large scale. Various seed borne mycoflora reduce seed quality and quantity in terms of both chemical composition and weight. Different biocides (bio-agents and plant leaf extract) used as seed treatment in vitro. Trichoderma viridae, T. harzianum followed by Pseudomonas fluorescens and FL-18 (bio-agent) and neem leaf extract followed by dhatura, mahendi, safeda and tulsi (leaf extract) proved to be effective in improving seed germination and vigour index by reducing pre- and post-emergence mortality.
