Research on Bio N was initiated in 1985 by Dr. Mercedes U. Garcia. The microorganisms from talahib were continuously screened under laboratory conditions and were found to be effective in enhancing nitrogen intake of plants. Laboratory tests and field experiments showed that it has improved the growth and yield of crops such as rice and corn. These experiments were then followed by screening tests in dry land and paddy conditions.

• Replaces 30-50% of the total nitrogen requirement of rice and corn.
• Increases yield of rice, corn, and vegetables.
• Makes plants healthy and green even in drought and in the presence of pests.
• Reduces incidence of rice tungro and corn ear-worm attack.

For corn:

1. One packet is good for 3-kg seeds in a container, moisten with water and put enough amount of Bio N™.
2. Mix thoroughly until the seeds are evenly coated.
3. Sow coated seeds immediately.  Do not expose the seeds to sunlight.
4. Apply a bag of 46-0-0 or 14-14-14 to a hectare as side dress.

For rice:

b. Pour the required amount of Bio N™. Make sure that all germinants

1. As liquid  inoculant for dapog bed: Mix Bio N™ in a sufficient  volume of clean water and evenly drench the seed/seedling-lined dapog bed.
