“…Studies have shown that the incapacity of several microorganisms to act jointly as effective inoculants in plant growth promotion is related to the root colonization process since bacterial cells grow and distribute through the rhizosphere depending on soil humidity, pH, temperature, microbial antagonism, space competence, radical exudates, as well as the physiological state in which the bacterium introduces itself and the likely specificity of the host. Facing these factors, only those cells capable of proliferating rapidly and invading the roots in a large number will achieve promoting plant growth effectively Pathak et al, 2017;Vejan et al, 2016).…”

The objective of this study was to determine the efficiency of applying microcapsules and liquid inoculation of three Pseudomonas putida strains on growth and yield of tomato plants in greenhouse where the results showed differences between both treatments. Rhizobacterial strains FA-8, FA-56, and FA-60 of P. putida, were assessed individually and combined to determine their capacity to produce indoleacetic acid (IAA). The three strains demonstrated the capacity to produce IAA in vitro, of which FA-56 stood out with 23.02 µg mL -1 in the microcapsule treatment with significant increases in plant height, stem diameter, radical volume, dry biomass, fruit yield, and rhizobacterial population (CFU). These responses could have been associated to the intrinsic capacity of this strain to produce a greater amount of IAA, hormone related to promoting plant growth. The use of plant growth-promoting rhizobacteria (PGPR) as biofertilizers by means of microcapsules could be an alternative in agricultural management and sustainable production of tomato. Immobilization of P. putida rhizobacteria by alginate microcapsules confers protection and gradual release, improving adhesion, permanency, and colonization of cells on the roots, promoting a better effect as PGPR and productivity in tomato plants.Alginate microcapsules (mc) †MIX = mixture of three rhizobacterial strains of P. putida. ‡liquid medium bacterial (lm).Average values (n = 8) within the same column with different letters denote significant differences in the assay with randomized block design and Duncan's multiple range test (P < 0.05).

Bioinoculants—Natural Biological Resources for Sustainable Plant Production

et al. 2021

Agricultural sustainability is of foremost importance for maintaining high food production. Irresponsible resource use not only negatively affects agroecology, but also reduces the economic profitability of the production system. Among different resources, soil is one of the most vital resources of agriculture. Soil fertility is the key to achieve high crop productivity. Maintaining soil fertility and soil health requires conscious management effort to avoid excessive nutrient loss, sustain organic carbon content, and minimize soil contamination. Though the use of chemical fertilizers have successfully improved crop production, its integration with organic manures and other bioinoculants helps in improving nutrient use efficiency, improves soil health and to some extent ameliorates some of the constraints associated with excessive fertilizer application. In addition to nutrient supplementation, bioinoculants have other beneficial effects such as plant growth-promoting activity, nutrient mobilization and solubilization, soil decontamination and/or detoxification, etc. During the present time, high energy based chemical inputs also caused havoc to agriculture because of the ill effects of global warming and climate change. Under the consequences of climate change, the use of bioinputs may be considered as a suitable mitigation option. Bioinoculants, as a concept, is not something new to agricultural science, however; it is one of the areas where consistent innovations have been made. Understanding the role of bioinoculants, the scope of their use, and analysing their performance in various environments are key to the successful adaptation of this technology in agriculture.

“…Environmental history places their existence from the Ovicadan era and they are believed to have been the facilitators of land invasion by plants (Redecker et al, 2000). These fungi belong to the phylum Glomeromycota and order Glomerales (Pathak et al, 2017). AM fungal species are functionally diverse and their ability to form symbioses is largely dependent on their ability to acquire food from the host, whether they confer the required benefits to the host and whether the host genotype allows AM fungi to complete their life cycles (Feddermann et al, 2010;Pathak et al, 2017).…”

“…The protein content is, however, dependent on variety, there being over 5000 potato varieties with varying degrees of nutritional value (Burlingame et al, 2009). This genetic diversity facilitates successful cultivation of potatoes in various agro-ecological regions across the continent (Dreyer, 2017), making it unique compared to other less diverse crops (Pathak et al, 2017).…”

The potato (Solanum tuberosum L.) is an important tuber crop with high dietary value that could potentially help to alleviate malnutrition and hunger in Africa. However, production is expensive, with high fertilizer and pesticide demands that lead to environmental pollution, and tillage practices that negatively affect soil structure. Microorganisms of different types have increasingly been found to be useful as biofertilizers, and arbuscular mycorrhizal (AM) fungi are an important crop symbiont. AM fungi have been shown to increase tolerance of crop plants to drought, salinity and disease by facilitating water and nutrient acquisition and by improving overall soil structure. However, the establishment and maintenance of the symbioses are greatly affected by agricultural practices. Here, we review the benefits that AM fungi confer in potato production, discuss the role and importance of mycorrhiza helper bacteria, and focus on how AM fungal diversity and abundance can be affected by conventional agricultural practices, such as those used in potato production. We suggest approaches for maintaining AM fungal abundance in potato production by highlighting the potential of conservation tillage practices augmented with cover crops and crop rotations. An approach that balances weed control, nutrient provision, and AM fungal helper bacterial populations, whilst promoting functional AM fungal populations for varying potato genotypes, will stimulate efficient mycorrhizal interventions.
