Cross inoculation of Bradyrhizobia among three common legume cover crops in rubber plantations of Sri Lanka

Abstract

Mixtures of legume cover crops are common in rubber plantations of Sri Lanka during the immature phase of rubber, and changes in ther composition occure with the changes in environment conditions due to the growth of canopies in rubber plants. Bradythizobial isolates from Pueraria phaseloides and desmodium ovalifolium were able to nodulate both legumes, but non of the isolates, including CB 756 (C.S.I.R.O collection, Queensland) produced nodules on Mimosa invisa.
