Status of Biofertilizers in Pakistan: Their Application and Advantages

Posted by Unknown On Wednesday, August 21, 2013

Biofetilizers are the organic fertilizers which contain living microorganisms which enhance the growth and production of the plant. Biofertilizers are getting very popular these days in Pakistan and by the passing minute the awareness of biofertilizer has been increased. We have already discussed the classification of biofertilizers

Now, we will see what kind of application is possible for biofertilizers; their advantages and limitations and finally a brief at the scope of biofertilizers in Pakistan agriculture system.

METHODS OF BIOFERTILIZER APPLICATION

They can be used either for seed treatment or soil application.

1.     Soil Treatment:

·         Mix both biofertilizers in compost and leave it overnight.
·         Apply this mixture in the soil at the time of sowing or planting.
·         In plantation crops apply this mixture near root zone and cover with soil.

2.     Seed Treatment:

·         Mix nitrogen and phosphorus biofertilizers in water and mix thoroughly.
·         Seeds are mixed this paste and dried in shade.
·         Sow the seeds as soon as possible.

3.     Seedling Root Dip:

·         For vegetables mix both N and P biofertilizers in water.
·         Dip the roots of seedlings in this suspension for 30-40 min before transplanting.
·         For paddy make a bed in the field and fill it with water.
·         Mix biofertilizers in water and dip the roots of seedlings for 8-10 hrs.

ADVANTAGES

·         Harmless and eco-friendly
·         Renewable source of nutrients
·         Low cost agro-input
·         Improve soil structure and WHC
·         Enhance soil fertility & fertilizer use efficiency
·         Increase crop yield by 20-30%
·         No adverse effect on plant growth and soil fertility
·         Supplement & replace 25-30% chemical fertilizers demand
·         Stimulate plant growth by secreting growth hormones
·         Release anti-fungal and antibiotic substances in soil

LIMTATIONS

·         Use of improper, less efficient strains for production
·         Requires qualified technical persons
·         High initial investment to production unit
·         Short shelf life
·         Seasonal demand for biofertilizers
·         Temperature sensitive
·         Prone to contamination
·         Low cell count

Status of Biofertilizers in Pakistan

·      Sustainable Agriculture is the new approach in agriculture and farming worldwide which focuses not to use chemical or synthetic fertilizers, or pesticides in agriculture and farming.
·      Microbial fertilizers are considered as the alternative to the traditional chemical or inorganic fertilizers for soil and plant. 
·      In the past ten to fifteen years, important scientific investments have been made into the use of microbial cultures with good economic benefits
·      New strategies are focusing on the awareness of common farmers to its potential application in the villages and leased land and also focus to lure farmers to no health issues related to use of biofertilizers as compared to chemical compounds.
·      Presently, different biofertilizers are being used for different crop in Pakistan and they are being manufactured by all leading fertilizer and seed companies while some are importing from abroad. For example, Rhizobium is being used for legumes, associative N2 fixing and PGPR for cereals.
·      Extensive research is also being done to improve quality and efficiency of microorganisms and reduction in production cost.
·      Scientists of Pakistan Atomic Energy Commission (PAEC) at NIBGE have developed a technology for large scale and cost effective production of biofertilizers along with their efficient delivery system to the end user - Biopower.

·      NIBGE scientists have done substantial work on BGA & Azolla, its cultivation and effect on rice yield.
