“…The development of nanoformulations containing Bt (or Bt-derived compounds) also holds great potential in increasing the shelf-life, efficacy and persistence in the field of these biopesticides (Devi et al, 2019). The development of nanobiofertilizers and nano-biopesticides will certainly be a step ahead in the innovative field of sustainable agriculture (Kumari and Singh, 2020). However, issues related to health and environmental toxicity of NPs will need to be properly addressed before the large-scale application and commercialization of such technology.…”

“…In addition, nanoencapsulation technology could be used to protect biofertilizer (and biopesticide) components, enhancing their shelf‐life and controlling their dispersion (Vejan et al ., 2016). Many PGPMs treated with gold‐, aluminium‐ and silver‐coated nanoparticles have been reported to significantly increase plant growth and to inhibit pathogen growth (Gouda et al ., 2018; Kumari and Singh, 2020). Recent studies have shown that the use of biocompatible titania and silica nanoparticles promoted the attachment and colonization of PGPMs, which resulted in plant biomass accumulation and growth improvements in stressful conditions (Timmusk et al ., 2018; Fetsiukh et al ., 2020).…”

Summary The use of microbial tools to sustainably increase agricultural production has received significant attention from researchers, industries and policymakers. Over the past decade, the market access and development of microbial products have been accelerated by (i) the recent advances in plant‐associated microbiome science, (ii) the pressure from consumers and policymakers for increasing crop productivity and reducing the use of agrochemicals, (iii) the rising threats of biotic and abiotic stresses, (iv) the loss of efficacy of some agrochemicals and plant breeding programs and (v) the calls for agriculture to contribute towards mitigating climate change. Although the sector is still in its infancy, the path towards effective microbial products is taking shape and the global market of these products has increased faster than that of agrochemicals. Promising results from using microbes either as biofertilizers or biopesticides have been continually reported, fuelling optimism and high expectations for the sector. However, some limitations, often related to low efficacy and inconsistent performance in field conditions, urgently need to be addressed to promote a wider use of microbial tools. We propose that advances in in situ microbiome manipulation approaches, such as the use of products containing synthetic microbial communities and novel prebiotics, have great potential to overcome some of these current constraints. Much more progress is expected in the development of microbial inoculants as areas such as synthetic biology and nano‐biotechnology advance. If key technical, translational and regulatory issues are addressed, microbial tools will not only play an important role in sustainably boosting agricultural production over the next few decades but also contribute towards other sustainable development goals, including job creation and mitigation of the impacts of climate change.

“…Cultivated plantsdepend mainly on the nutrient available forms from organic and inorganic sources to satisfy their needs. The mineral sources of nutrients may lead to several environmental problems e.g., groundwater pollution and its negative implications on human health (Kumari and Singh, 2019). Thus, these mineral fertilizers alone do not guarantee sustainable and safe production of food.…”

T HE world's burgeoning population faces a great challenge concerning food security, which could be achieved through different sustainable agricultural practices. Trichoderma, as a ubiquitous fungus, is one of the most promising microorganisms that might offer several avenues for sustainable agriculture. Trichoderma spp. may guarantee a better solution for conventional problems in agriculture through several approaches including the protection of cultivated plants from undesirable abiotic and biotic conditions under changing environments and promoting their growth in poor or limited soil nutrients. The promising role of Trichoderma for vegetable production as a biocontrol and biofertilizers has been confirmed but its role as a plant pathogen still needs more studies. Trichoderma could inhibit or suppress the growth of soil phytopathogens, promoting plant growth and soil health, through activation of many mechanisms including synthesis of antibiotics, mycoparasitism and competition for nutrients and space against plant deleterious microorganisms. The sustainable approaches of Trichoderma including biofortification, bio-remediation and phyto-remediationas well as exploring future research opportunities will be also addressed in this work.

“…The global rise in human population is driving a steady increase in the demand for food as it will be necessary to increment its production by 70 % in 2050, estimating that 90 % of the growth of agricultural production will be possible by obtaining higher yields, meaning crop intensification (FAO, 2009;Mahanty et al, 2017;Carrington, 2018;Adisa et al, 2019). The conventional agricultural system is designed for massive food production, increasing yields and decreasing production costs at the expense of high energy consumption and excessive use of fertilizers, pesticides and water; consequently, degrading the environment through air and water pollution, soil depletion, and loss of soil ecosystems and biodiversity (Horrigan et al, 2002;Glick, 2014;DeLonge et al, 2016;Mahanty et al, 2017;El-Ghamry et al, 2018;Kumari and Singh, 2019). Particularly, chemical fertilizers are extensively applied to sustain the growing demand for food.…”

“…Particularly, chemical fertilizers are extensively applied to sustain the growing demand for food. According to the FAO, worldwide consumption of chemical fertilizers was 191.98 million tons in 2019 (FAO, 2019), considering that plants use between 20 % and 50 % of the applied fertilizer, there is a high rate of fertilizer release into the environment (Drechsel et al, 2015;Tomer et al, 2016;Mahanty et al, 2017;El-Ghamry et al, 2018;Kumari and Singh, 2019). The Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) details that intensified cropping and rapid expansion of croplands have placed agriculture as the main driver of soil degradation (IPBES, 2018;Leahy, 2018).…”

Background: Agriculture is a major contributor to environmental and soil degradation. Soil microorganisms are essential to improve plant growth, crop yields and stress-tolerance. Objective: To characterize maize early plant-response in a seedbed setting to native consortia of isolated microorganisms from arid zones. Methods: Sixteen fungal and 16 bacterial isolates from arid soils were identified by MALDI-TOF MS and confirmed using morphological characteristics. Ten biofertilizers were tested in replicates (n=100) in maize under seedbed conditions. Consortia were formulated based on growth promoting traits, including mainly Penicillium and Pseudomonas species. After 45 days, biofertilizers were evaluated according to plant height, and shoot and root fresh weight. Results and Conclusions: Penicillium and Pseudomonas were the predominant genera identified. Most strains are potential candidates for biofertilizer formulation based on their growth promoting traits. Bacterial consortia mainly promoted plant caulinar development, while the combination of fungal and bacterial species markedly increased root development. Eight biofertilizer consortia from arid zones had positive effects at early developmental stage of maize under seedbed conditions compared to uninoculated plants.
