NitroPlus is a seed inoculant for legumes composed of bacteria called rhizobia in a solid-based carrier of soil and charcoal. The rhizobia form nodules with the legumes such as peanut, sitao, soybean, and mungbean. The legume-rhizobia symbioses fix the nitrogen from air making it available for the plants.

NitroPlus™ comes in powder form in 100-gram packet which can be used to coat seeds before sowing. The product has fertilizing value equal to 30 kg N/ha that can substitute chemical nitrogen fertilizer at reduced cost.

Rate of application: 

  • Peanut - 3 packs/ha
  • Mungbean - 4 packs/ha
  • Cowpea- 3 packs/ha
  • Pole Sitao- 2 packs/ha
  • Soybean- 10 packs/ha

Shelf-life: Six months

Avoid exposure to high temperature or direct sunlight.

How was NitroPlus developed?

Developed from 1974 to 1980, NitroPlus™ was the result of a six-year research to address the high cost and the increasing environmental problems caused by chemical nitrogen (N) fertilizers. Consisting of pure effective rhizobia grown in suitable carrier, NitroPlus™ was developed as a biofertilizer for legumes which will replace or supplement chemical N fertilizer.

What are the benefits of using NitroPlus?
  • Affordable and effective substitute for chemical nitrogen fertilizer.
  • Increases crop yield and income. Results of field trials showed an increase in yield of 100% for soybean, 29% for mungbean, and 39% for peanut.
  • Environment-friendly because it conserves soil nitrogen.
  • Easy to use.
How do you use NitroPlus?
  1. Use 2 packs of NitroPlus™ per hectare for pole sitao, 3 packs for peanut or cowpea, 4 packs for mungbean, and 10 packs for soybean.
  2. Put seeds in a large container and moisten them by sprinkling with tap water. Make sure that the seeds are moist but not soggy.
  3. Add NitroPlus™ to seeds. Be sure to use the right NitroPlus™ for the specific seed being used. Mix thoroughly until each seed is evenly coated. Note that the amount of NitroPlus™ depends on the legume to be planted.
  4. Plant the seeds as soon as possible. Be sure not to expose the inoculated seeds to sunlight.
