“…Further, significant and higher plant height was with the application of Azospirillum, might be due to its capability to produce Indole-3-acetic acid which helps in growth regulation of wheat. Similar results were reported by Karimi et al [9]. Another reason, significant and higher plant height was also increased with application of Azotobacter, might be due to the stimulation effect between Azotobacter and NPK on improving nutrient uptake, which in turn improves plant growth.…”

An experiment was carried out in the field during rabi season 2022-23 at Crop Research Farm, Department of Agronomy, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj (U.P.). The experiment was conducted to determine the response of wheat crop to different planting methods and biofertilizer application. There were nine treatments in the experiment, each replicated thrice and it was laid out in Randomized Block Design. The results showed that System of Wheat Intensification in combination with Azotobacter and Azospirillum recorded significant and higher plant height (101.93 cm), number of tillers / hill (12.91), plant dry weight (24.53 g), number of effective tillers / hill (9.78) and number of grains / spike (58.76). Whereas, Raised bed in combination with Azotobacter and Azospirillum significantly increased Leaf area index (3.66) and Crop growth rate (17.42 g/m2/day) compared to other treatments.

More than one hundred years have passed since the development of the first microbial inoculant for plants. Nowadays, the use of microbial inoculants in agriculture is spread worldwide for different crops and carrying different microorganisms. In the last decades, impressive progress has been achieved in the production, commercialization and use of inoculants. Nowadays, farmers are more receptive to the use of inoculants mainly because high-quality products and multi-purpose elite strains are available at the market, improving yields at low cost in comparison to chemical fertilizers. In the context of a more sustainable agriculture, microbial inoculants also help to mitigate environmental impacts caused by agrochemicals. Challenges rely on the production of microbial inoculants for a broader range of crops, and the expansion of the inoculated area worldwide, in addition to the search for innovative microbial solutions in areas subjected to increasing episodes of environmental stresses. In this review, we explore the world market for inoculants, showing which bacteria are prominent as inoculants in different countries, and we discuss the main research strategies that might contribute to improve the use of microbial inoculants in agriculture.

“…Presently, Rhizobium species are widely used in agriculture for their ability to fix nitrogen and form symbiotic relationships with leguminous plants [36]. Azospirillum, a gram-negative genus encompassing both rhizobacterial and endophytic strains, can also increase nitrogen uptake and plant growth [37,38].…”

Plant growth-promoting rhizobacteria (PGPR) boost plant growth and agricultural sustainability in an ecologically friendly way. The cultivation of chrysanthemum, a globally significant flower crop, has relied heavily on substantial agrochemical inputs that have detrimental impact on the environment. To assess the potential of chrysanthemum rhizobacteria to reduce this reliance, bacterial strains were retrieved from the plant rhizosphere and subjected to an assessment of various plant growth-promoting traits. Out of the 34 rhizobacterial isolates, 21 demonstrated the production of the plant growth hormone auxin, 21 had phosphate solubilization ability, 22 were capable of nitrogen fixation, and 21 could produce ammonia. Based on these findings, seven preeminent PGPR strains, characterized by multifaceted plant growth-promoting traits, were selected for subsequent studies and identified as species belonging to Acinetobacter, Bacillus, Pantoea, Serratia and Staphylococcus. The selected strains were systematically analyzed for their capacity to endure an array of abiotic stresses. A majority of these strains demonstrated adaptation under osmotic stress ranging from -0.15 to -0.49 MPa, temperatures of 20°C and 30°C, and salt stress within the range of 3 to 7% NaCl, which suggests their potential to promote plant growth across diverse environmental conditions. Additionally, the secretion of hydrolytic enzymes such as protease, pectinase and amylase was examined, and only the Staphylococcus hominis PGPR-12 strain demonstrated the ability to produce all three extracellular hydrolases. These findings underscore the potential application of multiple isolates possessing promising plant-probiotic properties to enhance plant growth across various conditions, thereby necessitating further exploration through pot and field assays.
