The study was carried out to assess the influence of different nodumax stickers on the nutrient and mineral contents of soybean varieties grown on an ultisol. In the trial, a split plot arrangement fitted into a randomized complete block design (RCBD) was used. The three varieties (TGX 1 448-2E, TGX 1 445-2E and TGX 1 485-1 D) made up the main plots, while the six nodumax inoculant stickers (gum arabic, milk, vegetable oil, no sticker, water and  control) made up the sub-plots. Pre-planting physico-chemical properties of the soils were determined to know the soil status, while inoculation was done in the field before planting. Grain nutrient and mineral contents such as crude protein, crude fat, crude fibre, ash, moisture content, dry matter, % phosphorus, potassium, calcium and magnesium were determined from the mature grain obtained at 12% moisture content. After the data analysis, the results revealed that variety significantly (P<0.05) affected the contents studied with variety TGX 1 448-2E giving the highest values, except for protein, fibre, phosphorous, iron calcium and magnesium content which were not significantly different from the others. The effect of sticker was also significant (P>0.05) on the nutrient contents studied except on iron and phosphorous which did not show any significant (P>0.05) difference. The values recorded in plots which had gum arabic as sticker was highest, though statistically similar to those with milk as sticker. Gum arabic, therefore, can be substituted with milk when gum arabic is not available.
