TABLE 5.
Field evaluation of different formulations of the autochthonous strain Rlp LCS0306 from Rhizobium leguminosarum.

The table includes the mean values of the parameters related with nodulation, nitrogen fixation, yield, yield components and HI for the combination of years and treatments. ANOVA values are in Supplementary Table S4. The formulation differed in the carrier, with the following options: Control consisting on perlite (Pe); compost (Co); compost 94% in weight plus biochar 6% in weight named as carbocompost (CC); perlite 25% in weight plus biochar 75% in weight (PB). For each dependent variable, mean values were compared to the control formulation with the Dunnet test, with the following significance levels: ∗∗0.001 < p ≤ 0.01; ∗0.01 < p ≤ 0.05; ns not significant. 1Corresponds to the commercial beans (11.57% dry matter).
