    Evaluation of various substrates for mycorrhizal inoculum production
    (Indian Council of Agricultural Research, 2022) Parihar, Manoj; Rakshit, Amitava; Rana, Kiran; Tiwari, Gopal; Singh Jatav, Surendra; Ram, Hanuman
    In the present study, six media were standardized to investigate their suitability for on-farm arbuscular mycorrhizal fungi (AMF) production by examining their physical condition and nutrient status which could be a major determinant of AMF propagule in the final product. The experiment was conducted with Sorghum as a host plant which was inoculated with Funneliformis mosseae and Rhizoglomus intraradices. Solirite alone recorded 4.66-24.66% higher root colonization than other medium while for spore density in per g of finished product, solirite and red soil mixture (106.33) was found superior followed by solirite and biochar mixture (94.33) and solirite alone (83), respectively, and lowest in soil medium (63 to 74). Moreover, spore density and root colonization were significantly and positively correlated (R2= 0.583, P<0.05) with each other. Solirite alone or mixed with other media improved water holding capacity and porosity with optimum nutrient availability which culminated in better host plant growth and ultimately higher number of AMF propagules. � 2022 Indian Council of Agricultural Research.

    Microbial biofertilizer: Types, applications, and current challenges for sustainable agricultural production
    (Elsevier, 2021) Gautam, Kamini; Sirohi, Chhavi; Singh, N. Raju; Thakur, Yourmila; Jatav, Surendra Singh; Rana, Kiran; Chitara, Manoj; Meena, Rajendra Prasad; Singh, Ashish Kumar; Parihar, Manoj
    With ever-increasing population of the world, which has now reached 7.75 billion, it has become a major challenge for world to meet the sustainable development goal (SDG) of zero hunger via meeting demand for food, feed, and other agricultural products especially in developing countries. Therefore, improving and sustaining agricultural crops yield without posing negative impact on environment should be the ultimate goal to meet food and nutritional requirement around the world. Application of chemical fertilizers although has increased the crop productivity but simultaneously has posed serious threat to human and environmental health. Therefore, biofertilizers from microorganisms have potential to replace these chemical fertilizers in sustaining agricultural productivity and maintaining environmental health. Moreover biofertilizers are easy to use and less expensive than chemical fertilizers. Biofertilizers includes one or more beneficial microbes that facilitate better nutrient uptake, greater production of growth hormone and beneficial phytochemicals in crops leading to higher quantity as well quality crop production. Nitrogen-fixing microbes, phosphate-solubilizing bacteria (PSB), sulfur-solubilizing bacteria (SSB), potassium-solubilizing bacteria (KSB), and vesicular-arbuscular mycorrhiza (VAM) etc. are already being utilized in combination for making biofertilizers formulations for enhancing crop production but on small scale. Thus, large scale exploitation of agriculturally important microbes for sustaining agricultural productivity is the need of the hour. This chapter highlights the types, quality control measures, inoculation techniques of microbial biofertilizers; their role in sustaining agricultural productionand challenges as well as ways forward to promote the use of biofertilizers in order to achieve sustainable agricultural production to meet out the SDG of zero hunger. � 2021 Elsevier Inc.

    Role of AM fungi in growth promotion of high-value crops
    (Elsevier, 2022) Parihar, Manoj; Chitara, Manoj Kumar; Ram, Hanuman; Kumari, Asha; Tiwari, Gopal; Rana, Kiran; Gorain, Bisweswar; Kumar, Utkarsh; Bisht, Jaideep Kumar; Kant, Lakshmi
    In order to meet the food demands of burgeoning population, innovative and efficient management practices are required for sustainable agricultural production. The high value crops (HVCs) including vegetables, horticulture, fruit and field crops such as potato, cotton, sugarcane etc. not only strengthen the financial security of farmers but also ensure their food, fiber and nutritional availability. To improve the productivity of HVCs, use of beneficial microbial symbionts such as arbuscular mycorrhizal fungi (AMF) is very promising and eco-friendly approach. The AMF form association with most of the land plants including agricultural and HVCs. They provide numerous benefits to the plants including better availability of water and nutrients, alleviate various biotic and abiotic stresses and promote plant growth. However, AMF response in improving the plant performance depends upon several other aspects such as soil environment, AMF strains, plant genotypes, agricultural management practices etc. In this regard, future research must be towards optimization of AMF plant association, suitable inoculum production and application techniques and co-inoculation of AMF with other plant growth promoting bacteria. In the present chapter we will discuss the state-of-the-art of potential of AMF to improve the production of HVCs, its application in micro-propagation program, commercialization and future advancement for sustainable production system. � 2022 Elsevier Inc.

    Zn-solubilizing microorganism: A novel perspective for sustainable agriculture
    (Elsevier, 2021) Pradhan, Surajyoti; Meena, Rajendra Prasad; Ram, Hanuman; Rana, Kiran; Parihar, Manoj; Singh, Ashish Kumar
    In the route to achieve higher production, intensive agricultural practices are followed, which are casting a negative impact on sustainability of the agroecosystem. Moreover, food security for a burgeoning population also demands the quality improvement in agricultural produce. According to an estimate, in developing countries ~33% of the population is deficient for zinc due to cereals-based food habits. However, an intensive production system and indiscriminate use of NPK-based chemical fertilizers also reduces the micronutrient content in soil and plant system. Among different micronutrients, deficiency of zinc (Zn) in the soil is most frequent, which reduces the agricultural production and also affects the normal growth and development of living beings. Therefore, to improve the Zn content in food grain and its availability in the soil system, some effective strategies are required to follow for sustainable agricultural production. Recently, the use of zinc-solubilizing microorganisms (ZnSMs) has been reported as a viable technology to enhance the bioavailability of native and applied Zn content in soil. In this regard, bacterial species such as Pseudomonas, Rhizobium, and Bacillus are found efficient and environmentally friendly in various studies. However, before presenting microbial approach as an alternative to synthetic fertilizers, comprehensive investigation regarding production aspects, marketing, availability to end user, quality, and application technology needs to be studied carefully. In this book chapter, we discuss the current knowledge, status, Zn-solubilizing mechanism, production, application, and marketing-related aspects of zinc-solubilizing microorganisms to explore them as green technology for sustainable agricultural production. � 2021 Elsevier Inc.
