Bio N is a microbial-based fertilizer composed of microorganisms (bacteria) isolated from the roots of talahib. This fertilizer enhances shoot growth and root development of rice, corn, and vegetables.
Storage: Keep in a cool, dry place
Shelf-life: 10 months from date of manufacture
Precaution: Avoid direct contact with inorganic or chemical fertilizers and avoid exposure to high temperature and direct sunlight.
Limitation: It is still necessary to apply 50% nitrogen
Rice – 5 packs/ha
Corn – 6 packs/ha
FREQUENTLY ASKED QUESTIONS
1. How was Bio-N developed?
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.
2. What are the benefits of using Bio-N?
- 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.
3. Is Bio-N for sale at BIOTECH? How much does it cost?
Bio-N is sold at Php60 per 200g.
4. How do you use Bio-N?
a. 1 packet is good for 3 kg of seeds in a container. Moisten with water and pour Bio-N.
b. Mix thoroughly until the seeds are evenly coated.
c. Sow coated seeds immediately. Do not expose the seeds to sunlight.
d. Apply a bag of 46-0-0 or 14-14-14 to a hectare as side dress.
a. As solid inoculant for direct-seeded rice or for sowing on a dapog bed.
b. Pre-germinate the seeds in gunny sacks or suitable containers. When radicles come out, place the seeds/germinants in a suitable container.
c. Pour the Bio-N and make sure that all germinants are evenly coated. Sow directly on the field or on prepared beds.
As liquid inoculant for dapog bed:
a. Mix Bio-N with clean water and evenly drench the seed/seeding-lined dapog bed.
As slurry for transplant seedling:
a. In a container, mix Bio-N with water to form a slurry.
b. Prune the roots of seedlings and dip for at least 30 minutes to 1 hour. Transplant.
