Nodulation and nitrogen fixation efficiency of cowpea as affected by inoculum rate
01/Nov/2012
Cowpea (Vigna unguiculata (L.) Walp.) can obtain sufficient N for its own supply from the atmosphere, by the process of biological nitrogen fixation (FBN), when associated with specific and effective rhizobia bacteria. The purpose of this study was to evaluate the effect of different rhizobia inoculum rates on nodulation and biological N fixation by cowpea (cv. BRS Pujante). A complete randomized block design with seven treatments and four replicates was used. The trial was conducted in a greenhouse using 2 […]
