Abstract

Chipilin (Crotalaria longirostrata) is a leguminous food crop native to Mexico and El Salvador. There is incentive to produce Chipilin for ethnic markets in the northeast; however, attempts to grow this plant in New England have not been profitable because Chilipin's optimal Rhizobium symbiont is unknown. Five Rhizobia strains were evaluated for their ability to form root nodules. Plant yield and minimum nitrogen fertilizer requirements were also measured across strains and three strains were identified to permit healthy chipilin growth in minimal Nitrogen fertilizer (5ppm). Nitrogenase activity was confirmed and quantified by a Ureide assay.
