Exploring Phyllosphere Bacteria for Growth Promotion and Yield of Potato (Solanum tuberosum L.)

Potato is an economical food, which belongs to genus Solanum (family Solanaceae) that consists of about 2,000 species and it provides a source of low cost energy to human diet. For vegetable purposes, potato has now become one of the most popular crops in India and cultivated in almost all states and under very diverse agro climate conditions. The states of Uttar Pradesh, West Bengal, Punjab, Bihar and Gujarat accounted for more than 80 per cent share in total production. At world level, China, India, Russian Federation, USA, Ukraine, Germany and Poland shared more than 62 per cent of total global production potato. India ranks second, next to China in global production of potato (Anonymous, 2016). Plant-associated bacteria colonize the rhizosphere (rhizobacteria), the phyllosphere (epiphytes) and inside of plant tissues (endophytes).

Screening of Epiphytic Isolates from Different Crops for Plant Growth Promoting Traits

Microorganisms are present in soil, near and above the roots and also present on aerial part of plants like leaves. Ruinen (1961) introduced term phyllosphere for plant leaf surface. The termed epiphytes used for inhabitants of phyllosphere. The diverse range of bacteria, filamentous fungi, yeasts and algae which are important for plant health and growth are present on phyllosphere (Whipps et al., 2008; Vorholt, 2012). The total count of microbes approximately is about 6.4 x 10 8 km 2

Biosynthesis of Nanoparticles by Microorganisms and Their Significance in Sustainable Agriculture

An assuring novel technique in the field of micro-biotechnology is the application of potential microbes for producing inorganic nanoparticles. These biological agents are safe, eco-friendly, and good source of producing green nanoparticles. Since large species of microbial agents with different metabolic complexities have potential of producing metal nanoparticles (NPs), the exact means or procedure of nanoparticle synthesis is not well understood. The interest in the nanotechnology field is triggered by exclusive assets of nanoparticles and their possible and probable fields of application including electronics, medication, and agriculture. With the ever enhancement in global populace and demand for food, the nanotechnology technique may be the most hopeful and reassuring way to improve the overall agricultural production. The potential applications of nanoparticles in agriculture sector include biosensors; gradual, time-consuming, and controlled delivery of chemical fertilizers and pesticides; detection and control of plant diseases; soil and water remediation; etc. At present however the use and employment of nanotechnology in the agricultural field is in the infant stage; however, if discovered gradually and used in a sustainable way, this new technology can help in the orientation of our agriculture and society today to new heights in the future.
