Bio fertilizers are defined as preparations containing living cells or latent cells of efficient strains of microorganisms that help crop plants’ uptake of nutrients by their interactions in the rhizosphere when applied through seed or soil. They accelerate certain microbial processes in the soil which augment the extent of availability of nutrients in a form easily assimilated by plants. Use of bio fertilizers is one of the important components of integrated nutrient management, as they are cost effective and renewable source of plant nutrients to supplement the chemical fertilizers for sustainable agriculture. Several microorganisms and their association with crop plants are being exploited in the production of bio fertilizers. They can be grouped in different ways based on their nature and function..

Mycorrhiza (fungus roots) is a distinct morphological structure which develops as a result of mutualistic symbiosis between some specific root – inhabiting fungi and plant roots. Plants which suffer from nutrient scarcity, especially P and N, develop mycorrhiza i.e. the plants belong to all groups e.g. herbs, shrubs, trees, aquatic, xerophytes, epiphytes, hydrophytes or terrestrial ones. In most of the cases plant seedling fails to grow if the soil does not contain inoculum of mycorrhizal fungi.

Benefits of Mycorrhizas to Plants : They increase the longevity of feeder roots, surface area of roots by forming mantle and spreading mycelia into soil and, in turn, the rate of absorption of major and minor nutrients from soil resulting in enhanced plant growth.They play a key role for selective absorption of immobile (P, Zn and Cu) and mobile (S, Ca, K, Fe, Mn, Cl, Br, and N) elements to plants. These are available to plants in less amount.Some of the trees like pines cannot grow in new areas unless soil has mycorrhizal inocula because of limited or coarse root hairs. Mycorrhizal bio fertilizer enhance water uptake in plants. They reduce plant response to soil stress such as high salt levels, toxicity associated with heavy metals, mine spoils, drought and minor element imbalance. They increase resistance in plants and with their presence reduce the effects of pathogens and pests on plant health.

HPM’s contribution for agriculture : The country’s leading company HPM India is doing a lot of commendable work. For the betterment of farmers company is providing them the best quality insecticides, fungicides, herbicides and plant growth regulators. The company has brought a new product to make agriculture better, Which is a bio fertilizer.

HPM’s Mycorrhizal Bio- Fertilizer : HPM GOLD is unique product containing microbes as Vesicular-Arbuscular Mycorrhiza (VAM) and has broad spectrum action in granular form. It contains granular spores and other propagules of VAM Mycorrhizal Fungi in a granular carrier and has broad spectrum fertilizer activity. Due to high solubility in water it is absorbed rapidly through plants and roots, resulting maximum supply of compost and micronutrient to the crop. HPM Gold improves the roots growth with excellent root setting, resulting greenness by vanishing yellowing in crop. It helps in greater utilization of nutrients, and provides plant protection from disease causing organism to the root and also makes insect resistant plant. Its mycelial threads penetrate inward into the root, thereby increasing the surface area for absorption and translocation of essential plant nutrients including Phosphorus, Nitrogen, Sulphur, Calcium, Zinc and copper. It is completely safe to use HPM Gold. It also combats with the drought and stress loss by the crop.
