Effect of water deficit and sowing date on oil and protein contents in soybean co-inoculated with Azospirillum brasilense

ABSTRACT The soybean chemical composition is strongly influenced by genetic factors, as well their interaction with the environment and management practices. Among environmental water deficit temperature are those that most contribute to modify of beans, especially oil protein contents. present study aimed assess effects co-inoculation Azospirillum brasilense on Two field experiments were carried out different sowing dates. design consisted randomized blocks, in a split-split-plot arrangement, four replications, including two irrigation depths (25 % 100 ETc), inoculation methods [Bradyrhizobium japonicum (strains Semia 5079 5080) AbV5 AbV6 + Bradyrhizobium japonicum)] cultivars (ANTA 82 TMG 132). did not affect contents beans for any assessed conditions. reproductive stage, combined dates, altered both cultivars, showing, respectively, higher average content 132 ANTA 82.
