Effects of Nitrogen Fertilization and Soil Inoculation of Sulfur-Oxidizing or Nitrogen-Fixing Bacteria on Onion Plant Growth and Yield

Table 1

Effects of different rates of nitrogen (kg ha⁻¹) without or with inoculation of sulfur-oxidizing bacteria (SoxB) and soil inoculated with SoxB and N-fixing Bacteria (NFxB) on onion plant growth parameters and bulb yield.
