Analysis of variance for the effects of different Mo concentrations, adhesive agents and their interactions on plant height, aboveground biomass, the number of nodules, nodule weight and nitrogenase activity in alfalfa.
Fig 2.
Plant height and aboveground biomass of alfalfa inoculated with two rhizobia seed coat formulations.
Between the four Mo concentrations under the control treatment, bars that do not share capital letters are significantly different (P < 0.01). The data are presented as means ± SE. *** P < 0.001; NS P > 0.05. Abbreviations are as follows: Adhesive agent (AD), Ammonium molybdate concentration (Mo), Carboxymethyl cellulose (CMC), Sodium alginate (AE), Sodium alginate + skimmed milk (AES).
