Nodulated Legumes of Coastal Andhra Pradesh

Abstract

A survey of nodulation was carried out in coastal regions of Andhra Pradesh and nodulation characteristics of 92 legume species were recorded. All the plants belonging to Fabaceae and Mimosaceae showed nodules, while in Caesalpinaceae except for one species viz., Cassia absus, none of the species showed nodules. The nodulation status of six species viz., Crotalaria hirsuta, Indigofera cassioides, Rhynchosia suaveolens, Tephrosia pulcherima, T. spinosa and Acacia sundra is reported for the first time. Apart from these six species, the nodulation of 13 other nodulating species was also recorded for the first time from India.
