3. Introduction As the agriculture moves towards modernization, the frequent use of synthetic fertilizers is increased. Excessive use of chemical fertilizers directly or indirectly causes soil ill health, soil pollution and declines crop productivity. The importance of biofertilizer as a component of integrated Nutrient Management (INM) is viewed as sustainable crop production system, not only on yield maximization but also for the agro-system stability. In this RLO, types of biofertilizers, importance and methods of their application are being described. Next Previous End

4. Importance of Biofertilizer The importance of biofertilizer in crop production is detailed as following: Biofertilizer is a natural organic fertilizer helps to provide all the nutrients required by the plants and helps to increase the quality of the soil with a natural microorganism environment. It is the most advanced tool of bio technology necessary to support developing organic agriculture, sustainable agriculture, green agriculture and non-pollution agriculture. This Bio-organic Fertilizer can increase the output, improve the quality and it is responsible for agriculture environment. It is well known that the continue use and overuse of petrochemical based fertilizers and toxic pesticides have caused a detrimental effect to our soils, water supplies, foods, animals and even people.

5. The Biological Grower is more sensible with sustainable approach and employs the resources of both science and nature to allow better results in his production. For centuries, peat moss has been recognized soil bacteria, fungi, earthworms, and other bio-organisms to enrich the soil to produce safe, nutritious and abundant crops. It is an excellent fertilizer sources. All natural organic fertilizers made with pure peat moss. Biofertilizer Contains a wide range of naturally chelated plant nutrients and trace elements, carbohydrates, amino acids and other growth promoting substances. It acts as a soil conditioner by stimulating microbial activity in the soil which results in improved air-water relationships in soil, improved fertility and makes soil less prone to compaction and erosion.

6. This blend makes an excellent foliar fertilizer. Besides being a nutritionally complete fertilizer (containing even calcium), the nutrients are readily absorbed by the leaf. Foliar applications on a regular basis can increase the health, vigor and yield of plants due to this easily absorbed additional nutrition. Since these fertilizers are eco-friendly they can be used generously to promote healthy crops. The quality of the soil is also improved thanks to these environmentally friendly fertilizers.

9. Vesicular Arbuscular Endomycorrhiza Mycorrhizae is the symbiotic association between plant roots and soil fungus of the 7 types of mycorrhizae, VAM plays a great role in inducing plant growth. VAM are symbiotic entophytic soil fungi, which colonize the roots of approximately 80% plants. VAM fungi produce hyphae, which are microscopic tubes that colonize crop roots and grow out into the soil further than root hairs. Nutrients are taken up by the hyphae and carried back to the plant. This results into very efficient mobilization & uptake of fertilizers and other nutrients by plants. The VAM hyphae also help is retaining moisture around the root zone of plants. (Cont)..

10. The VAM hyphae also help is retaining moisture around the root zone of plants It increases the resistance to root borne or soil borne pathogens and Nematodes. Enhanced colonization of introduced population of beneficial soil organisms like Azotobacter, Azospirillum, Rhizobium and Phosphate solubilizing bacteria around mycorrhizal roots thereby exerting synergistic effects on plant growth. Next Previous End

11. Advantage of VAM: VAM is highly versatile and colonizes 85 % of the plant families. It penetrates the roots, forms arbuscules and vesicles in the cortical cells of the roots and hyphae and spores in the soil. The mychorrhiza penetrates the roots, mobilizes & supplies phosphorous and other micronutrients to the plants. Solubilize phosphate and transports micronutrients such as zinc, Manganese, iron, copper, cobalt, molybdenum etc. from the surrounding area to the plant. Increase the plant vigor by inducing drought resistance of young seedlings. VAM protects the plants from the fungal pathogens. Next Previous End

16. B. METHOD OF APPLICATION The biofertilizers may be applied in soil or suckers of banana plants. The detail of procedure is given as below: 1.6 Soil application: • Mix 4 kg each of biofertilisers in 200 kg of compost and leave it overnight. • 200 g per sq.mt. in seed/nursery bed. • 2 g per seedling in the Nursery stage • 5 g per seedling at the time of planting • 10-15 g per garden trees and fruit trees respectively. • 100-200 g per plant of grown tree species. • 3-5 kg/acre of VAM can be applied in 2-3 cm depth. • Mix 4 kg each of biofertilisers in 200 kg of compost and leave it overnight. • Apply this mixture in the soil at the time of sowing or planting.

17. Sucker treatment: Suspend 200 g N biofertilizer and 200 gms Phosphotika in 300-400 ml of water and mix thoroughly. Mix this paste with 10 kg seeds & dry in shade. Sow immediately. Dip the roots of seedlings in this suspension for 30-40 min before transplanting. Next Previous End

19. Orchards: Apply at the root zone of individual trees or vines directly early in the season @ 3-4 ml / liter of water. Application through irrigation: Apply 50ml to soil along with irrigation by drip/sprinkler per acre. Next Previous End

20. Precautions: • Store biofertilizer packets in cool and dry place away from direct sunlight and heat. • Use right combination of biofertilizers. • Rhizobium is crop specific, so use in specified crop. • Do not mix with chemicals. • While purchasing ensure that each packet is provided with necessary information like name of the product, name of the crop for which intended, name and address of the manufacturer, date of manufacture, date of expiry, batch No and instructions for use. • Use the packet before expiry, only on the specified crop, by the recommended method.

21. To sum up Use of chemical fertilizer leads to cause of soil deterioration and water pollution. In view of the disadvantages associated with the use of chemical fertilizers, it is important to use alternative sources, which are environment friendly. Biofertilizers, most of which are nitrogen fixing microorganisms, are considered to be suitable alternative source of plant nutrition. Farmers can adopt this technology to improve the land resources and save natural environment. Previous
