Abstract

In bioassay and pot culture, the allelopathic influence of pulp extract of Syzygium cumini L. fruit on 3-crops, [Oryza sativa Linn. (cv. Ranjit), Zea mays Linn. (Cv. Vijay Composite) and Vigna radiata Linn. (Cv. SG-1)] were determined. The pulp extracts significantly (P < 0.05) suppressed the germination, growth and biomass yield in both bioassay and pot culture. The O. sativa test crop was more susceptible to toxins in pulp extract followed by Zea mays. Irrespective of test crops, the pulp extract reduced the germination, shoot length, root length and biomass yield by 22.2, 28.1, 27.8 and 32.5%, respectively.
