Soybean Response to Rhizobial Inoculation in Northern Mozambique.

Inoculation can enhance the growth and yield of soybean through symbiotic nitrogen fixation. However, this agronomic practice is not commonly known by soybean producers is Mozambique. The objectives of this study are to assess the effects of seed inoculation method using liquid and peat-based inoculant formulations and soil-applied granular inoculation on nodulation, nitrogen fixation and yield of soybean. Field experiments were conducted at two sites in Northern Mozambique during the 2007/2008 growing season using two soybean varieties: TGX 1937-1F and Solitaire. Seeds were planted on 23 and 25 January 2008 at the two sites and rhizobial inoculants consisting of liquid, peat-based and granular formulations were used. Data is not available yet but we expect to report the efficacy of the inoculation methods at the experimental sites. TGX 1937-1F is promiscuous in nodulation and will provide information whether inoculation is necessary for these newly introduced promiscuous varieties in Northern Mozambique.
