The Role of Bio-Fertilization in Improving Fruits Productivity—A Review
Advances in Microbiology, 2014
Biofertilizers consist mainly of beneficial microorganisms that can release nutrients from raw materials and plant residues in the soil and make them available commercially where specific strains are used as biological fertilizers. They become recently, positive alternatives to chemical fertilizers because they help bring down the costs of chemical fertilizers especially N and P and improve soil fertility by maintaining the physical properties of the soil. They may help in improving crop productivity and quality by increasing the biological N fixation, the availability and uptake of nutrients and stimulating the natural hormones. They are safe for humans, animals and environment and using them is accompanied with reducing the pollution occurring in our environment.

Effective Utilization of Biofertilizers in Horticultural Crops
Introduction Plant needs nutrients for their growth and development. In a systemic agriculture, nutrients are supplied to the plant in different amount, form and time for the economic and optimum crop production. Green revolution realized in the late sixties of the last century is an outcome of efficient use of improved varieties and nutrient management. Success of the green revolution has increased use of chemical fertilizers in the post green revolution era. Soon the chemical fertilizers become indispensible from all the crops including vegetable and plantation crops. Non judicious use of chemicals in the agriculture has lead to the serious health, soil and environmental hazards. Biofertilizers are considered to be the most safe, promising and economic component of sustainable agriculture. Biofertilizer is a substance which contains living or latent microorganisms which, when applied to seed, plant root or soil, colonizes the rhizosphere or the interior of the plant and promotes growth by providing and essential nutrients or increasing the supply or availability of primary nutrients to the host plant. They can applied in all the agronomic, horticultural and plantation crops. Research work carried out at Navsari Agricultural University proved that biofertilizers have potential to reduce the use of chemical fertilizers to the tune of 50 per cent and increase the productivity upto 20 per cent. The microorganisms in biofertilizers restore the soil's natural nutrient cycle and build soil organic matter. Through the use of biofertilizers, healthy plants can be grown, while enhancing the sustainability and the health of the soil. Apart from providing nutrients,

Role of biofertilizers in vegetable crop production: A review
International journal of chemical studies, 2020
The increasing impact of agricultural practices on environment in the world have progressively affected the soil quality in both cases i.e soil structure as well as soil biological balance, which requires the advancement of substitution of practices to minimize and lessen those impacts, parallel to the improvement on yield per cultivated area and economic benefits for producers and farmers. In addition to this, the quantity of foodstuff that today's society require for processing and supply of the industry has encouraged the standard of new options for agricultural practices, tending to be: i) Less invasive to environment ii) Cost effective than conventional methods iii) Enhanced efficiency at low costs iv) Better quality of harvests and v) Simplified use of implements with no undue technical needs. Consequently, a technology i.e biofertilization came into existence so as to curtail environmental impacts and take full advantage of the available resources. Biofertilizers have clear-cut benefits over chemical inputs. Chemical fertilizers supply N, P, K whereas bio-fertilizers provide besides N,P,K certain growth promoting substances like hormones, vitamins, amino-acids, etc. Bio-fertilizers are well-known as a substitute to chemical inputs to augment soil fertility and crop production in sustainable farming. The application of bio-fertilizers efficiently enriches the soil and costs not more than chemical fertilizers, which harm the environment as well as exhaust non-renewable energy sources. The application of chemical nitrogen and phosphorus fertilizers at higher levels leads to accumulation of NH4 + , NO3-, NO2-, PO4in vegetable product tissues. Therefore clean agriculture recently depends upon using biofertilizers as well as organic products so as to give high yields with the best product quality devoid of contamination and less accumulation with heavy metals.

Use of Biofertilizers in Agricultural Production
Intechopen, 2021
Most of agricultural production in Latin America consists of smallholder farmers who need the development of sustainable technologies, with costs according to their economic condition. Biofertilizers composed of free-living bacteria promote plant's growth, improve productivity through the strengthening of its roots, and reduce the amount of synthetic fertilizer applied to the crops. The aims of this chapter are to highlight the microorganisms commonly used in agriculture as biofertilizers and the main researches carried out in several countries of Latin America, and to describe the development of an experimental biofertilizer for maize, based on strains of Azospirillum spp. and Pseudomonas fluorescens, in the highlands (Sierra Region) of Ecuador. Seven phylum and 95 genera o microorganism used as biofertilizers or Plant Growth-Promoting Rhizobacteria (PGPR) are summarized, along with the benefits, challenges and future prospect of their use. The effectiveness of the experimental biofertilizer developed in Ecuador was demonstrated through several experiments at the green house and field, in which it was evident the increase of root's size, the amount of crocket, the percentage of dry matter, and the crops´ yield. The evaluations, accomplished on farmers' fields showed 30% of increase in yield and 21% of decrease in the cost of production per kilogram; as a consequence of the use of biofertilizer plus 50% of the recommended chemical fertilization, in comparison with standard farming techniques. Farmers can reduce the application of synthetic fertilizers and sustainably increase crop yield through the use of this technology.
