Effect of weed extracts on enzymatic analysis of Vigna unguiculata (L.) Walp and Lablab purpureus (L.) Sweet

Important field crops grow less successfully contaminated by weeds. The environment and human health have suffered severely from improper weed control methods and the unnecessary and inappropriate application of chemical fertilizers, and caused an increase in weed variety resistance. The phytochemicals found in allelopathic plants have gained importance as potential biological equivalents for synthetic herbicides. The enzyme activity of Lablab purpureus (L.) sweet and Vigna unguiculata (L.) Walp can be impacted allopathically by weed extracts. In Vigna unguiculata (L.) Walp and Lablab purpureus (L.) sweet, the enzyme activities of Phyllanthus niruri (L.) and Chloris barbata Sw. weed extracts treated as foliar sprays were assessed throughout the pre-flowering, flowering, and post-flowering stages. This work shows that an aqueous weed extract of Lablab purpureus (L.) sweet and Phyllanthus niruri (L.) and Chloris barbata Sw. can enhance enzyme activity in Vigna unguiculata (L.) Walp, hence providing the possibilities for the development of plant growth.
