Biofertilizer  contains living microorganisms which, when applied to soil, colonizes the rhizosphere or the interior of the plant and promotes growth by increasing the availability of primary nutrients to the host plant.   Classification of Biofertilizers (Cover) Types of Biofertilizers The various types of biofertilizers which help the plant to grow at different levels of its growth are: 1.  Nitrogen Fixing Biofertilizers 2.  Phosphate Biofertilizers      a.  Phosphorous Solubilizing Biofertilizers      b.  Phosphorus Mobilizing Biofertilizers 3.  Biofertilizers for Micro-nutrients 4.  Plant Growth Promoting Rhizobacteria 5.  Compost 1) Nitrogen Fixing Biofertilizers i. Increase soil nitrogen level ii. Fixes the atmospheric nitrogen in the soil and make it available to the plants  Examples: Azotobacter , Nostoc , Rhizobium , Azospirillum a) Azobacter i. Free living N-fixing bacterium ii. Non-leguminous plants b) Cyanobacteria i. Nostoc/Blue green algae ii. Free-living as well as sym

A fertilizer is any organic or inorganic material that is added to a soil to supply essential plant nutrients for growth.  Chemically synthesized inorganic fertilizers are widely used.  Fertilizers enhance crop yield by 30-50% and provide micro and macronutrients to the exhausted soils . Biofertilizers Biofertilizer contains living microorganisms which, when applied to soil, colonizes the rhizosphere or the interior of the plant and promotes growth by increasing the availability of primary nutrients to the host plant.   Introduction to Biofertilizers (Cover) Biofertilizers c ontain living cells or latent cells of efficient strains of microorganisms. They are eco-friendly and cause no danger to the environment. These can also be called as "Live Fertilizer" and most commonly used in  Organic Farming/Agriculture . How Biofertilizer Work? 1. Enrich the soil with microorganisms to produce organic nutrients 2. Add nutrients through the natural processes like:         i. Nitro

Various factors are responsible for the efficiency of extension system but farmers' demands and their needs for advisory services are decisive factors in determining the effectiveness of extension services.  Demand-driven and need-based advisory services ensure the efficiency of extension system. Agriculture Extension (Need of Farmer Advisory Services in Punjab, Pakistan) - Cover Why we need Extension Services? The agriculture, being the second largest sector, plays a significant role in Pakistan's economy.  It accounts for 21 percent of GDP, and ranks first in contributing 45 percent to its total labor force .  About 62 percent of country�s population is directly or indirectly linked with agriculture for their livelihood.  The agriculture sector supplies raw materials to agro-processing industry.  It contributes substantially to Pakistan�s exports , and  A large market for agricultural inputs such as tractors, seed, fertilizer, pesticides, etc. Desired Solution: Various
