Biofertilizer from Parthenium

By NfN Network
Kalyani, March 9: The agronomists engaged in research works at Bidhan Chandra
Krishi Viswavidyalay on invasive weeds have found that Parthenium, which is one
of the most poisonous invasive weeds, can be used to make a high-quality
eco-friendly balanced bio fertilizer. The new research finding is set to add a
new dimension to the rural economy and to combat this deadly weed which play a
key role in loss of crops and cause ecological imbalances.

The agronomists have produced a ‘compost’ using non-flowering young
Parthenium plants, which is more effective than Vermicompost or any other
traditional composts. The agronomists feel that this so far the best way to
minimize population of parthenium.

Elated over findings the BCKV recently organized the first awareness programme
on invasive weed in Kalyani. It also organize training programme for the
farmers.

At present the ‘Parthenium compost’ is being used on trial basis at
different farms of the BCKV. A team of scientist headed by Professor Dr.
Ratikanta Ghosh of Department of Agronomy at present working for its further
development. When Dr. Ghosh asked said: “We owe the basic concept to NRCWS of
Jabalpur, which has been further modified and developed by our scientists.”

The scientists have used cow dung, soil, water with Parthenium plants in proper
proportions. All these are put in a pit, following which urea or rock phosphate
are sprinkled for rapid decomposition. Later Trichoderma viridi, a type of
fungus and layers loamy soil are added in the compost. It takes around four
months to complete the entire process of decomposition.

Professor Ghosh said: “Parthenium compost can be used in crops, vegetables and
in orchards”.” “Moreover, it has no harmful effects and except nitrogen it
has all the nutrients like Phosphorus, Potash, Calcium, and Magnesium more than
Vermicompost.”
