About Mucuna bracteata:
- It isan invasive cover crop. It is a leguminous vine which was introduced to rubber plantations as a weed protectant and nitrogen regulator valued for its drought tolerance.

Q1: What are leguminous crops?
Leguminous crops are those which belong to the pea family (Leguminosae). Plants in this family generally have root nodules hosting rhizobium bacteria that fix nitrogen from the atmosphere. When plant residues decompose, this fixed nitrogen can increase soil nitrogen content.
