As a result of an extensive isolation and screening program, researchers tested and made available to Thailand and the Philippines a number of Rhizobium strains that consistently increase yields of peanuts under field conditions. These strains can compete with the indigenous rhizobia and give seed yield increase over both the normally available strains and recommended nitrogen fertilization (Philippines). Several of the strains were infused in commercial peanut inoculant produced in Thailand, the Philippines, India and the United States. As a spin-off to our CRSP-related activities, the researchers provided inoculant and technical expertise for peanut field trials in Cameroon (funded out of technical assistance), Sudan, and Pakistan.
