Abstract:
Background and Objectives: Although, the pharmacological and/or pharmaceutical properties of R. communis have been found in literature, research articles about its allelopathy on different field crops species is rarely reported. Therefore, aqueous extracts of different plant parts of R. communis were examined to investigate their allelopathic potentiality. Materials and Methods: Different plant parts of R. communis (leaf, twig, bark, stem, root, pericarp and seed) extracts at four different concentrations viz. 1:5, 1:10, 1:15 and 1:20 (w/v) along with control were tested against jute, mungbean, mustard, radish, rice, wheat and tomato. The experiments were conducted under Completely Randomized Design (CRD) with three replicates. Results: The inhibitory activity of R. communis on different field crops were concentrations and plant parts dependent. Most of the plant parts at lower concentration stimulated the shoot and root growth of all test crop species. The root growth of the test crop species was more sensitive than their shoot growth. Among the test crop species, the shoot and root growth of mustard were most sensitive followed by radish to the different plant parts extract of R. communis. Whereas, the shoot and root growth of rice was less sensitive followed by tomato and mungbean. Among the plant parts, twig showed most phytotoxic activity on the test plants. Conclusion: The R. communis has allelopathic properties and may possess allelochemicals. Since, twig of R. communis extracts had greater inhibitory activity than other parts, this plant parts could be used for isolation and identification of allelochemicals for sustainable agriculture.
