Compositions for enhancing grain yield and protein yield of a legume grown under environmental conditions that inhibit or delay nodulation thereof are provided. The compositions comprise a PGPR strain. In a particular embodiment the PGPR strain is of the genus Serratia. Moreover, methods for enhancing grain yield and protein yield of a legume grown under environmental conditions that inhibit or delay nodulation thereof are provided. The methods comprise an addition of an agriculturally effective amount of a PGPR strain in the vicinity of the seed or root of the legume.

L'invention concerne des compositions permettant d'améliorer la production de graines et la production de protéines d'une légumineuse cultivée dans des conditions de contraintes environnementales qui empêchent ou retardent la formation de nodosités sur cette légumineuse. Ces compositions contiennent une souche de rhizobactéries stimulant la croissance des plantes (PGPR). Selon une réalisation particulière, la souche de PGPR est du genre Serratia. En outre, l'invention concerne des procédés permettant d'améliorer la production de graines et de protéines d'une légumineuse cultivée dans des conditions de contraintes environnementales qui empêchent ou retardent la formation de nodosités sur cette légumineuse. Ces procédés consistent à ajouter une quantité agronomiquement suffisante d'une souche de PGPR à proximité des graines ou de la racine de la légumineuse.
