Majority of the medicinal plants belong to angiospermic families of
which legume family (Fabaceae) is the third largest, with approximately
650 genera and 20,000 species. A handsome number of medicinal legumes
are potential sources of glycosides (aloe-emodin, chrysophenol, emodin,
and rhein etc.), antibiotics, flavonoids, alkaloids and phytochemicals,
which are used in drug manufacturing by the pharmaceutical industries.
Among them, hyacinth bean, senna sophera, coffee senna and cassia tora
constitute the most important source of therapeutic agents used in the
modern as well as traditional systems of medicine. For the cultivation
of plants, the role of mineral nutrition is of paramount importance.
Generally legumes require high amount of phosphorus and calcium for
their growth, nodule formation and N2-fixation. Hence, intensive
research efforts should be expanded for maximizing the yield of
potentially useful leguminous medicinal plants particularly through
optimal supply of the required fertilizers. This work provides valuable
information regarding mineral nutrition strategies for the cultivation
of medicinally important leguminous plants.
