Inoculant Maturity Influences Survival of Rhizobia on Seed

RESUMO

Survival of Rhizobium trifolii on seeds of arrowleaf clover (Trifolium versiculosum Savi) and subclover (Trifolium subterraneum L.) was affected by the maturity of peat-, vermiculite-, and charcoal-based inoculants. Ten times more rhizobia survived on seed 4 days after inoculation when inoculants were stored (cured) before being utilized as compared with uncured inoculants. Increasing the curing time of inoculants beyond 4 weeks had little effect on increasing survival of seed-applied rhizobia.
