Abstract

A greenhouse study was set up, with two Neonotonia wightii cultivars, to verify the effect of inoculation with rhizobia (6), together actinomycetes (5) or fungi (3) that produce in growth medium rhizobium inhibition agent, in plant shoot growth and nodulation response. After sixty days of germination, the mean values variated from 410 to 600mg/plant for shoot dry weight, from 19 to 32mg/plant for nodules dry weight and from 16 to 24 nodules per plant. There was hight correlation between shoot dry weight and nodules dry weight, or number of nodules with diameter between 2 and 4mm or nodule number per plant. The data showed significant differences between cultivars and between rhizobia but the together inoculation of rhizobia and the other microorganisms that produce, in culture medium, inibition agents to rhizobia did not influence the nodulation and legume growth.
