“…Our results are consistent with the fndings of Estrada-Bonilla et al, 2021 [9] which indicated that in contrast to fertilizer amendment, simultaneous application of PSB strains and compost amendment showed signifcant improvement in physical, chemical, and biological soil properties which improved shoot nutrition and growth. In contrast, many reports have indicated that fertilizer and PSB inoculation among other treatments has shown notable success in diferent crops production and productivity such as maize [3,8], Allium cepa L. [32], tomato [20], 2017; [28,34], mung bean [17], rice [7], and wheat [16].…”

“…Soil nutrients could be supplemented as biowastes, organic matter, fertilizers, and/or biofertilizers. Biofertilizers such as nitrogen fxers, PSB, and mycorrhizal fungi application alone or together [2,17] improve soil nutrients, root and shoot growth as well as maintain plant and soil health.…”

“…Generally, Verma et al 2019 [5] summarized that PGPR benefts plants in four major processes, namely, plant growth enhancement, biocontrol, stress management, and soil renovations by rhizoremediation. PSB are known PGPR [3,12] with multidimensional benefts [17] including broad host range interaction, accessing nutrients, phytohormone induction, stress alleviation, biocontrol activity, resistance enhancement, and eco-friendly approach [8].…”

Phosphate solubilizing bacteria have multi-dimensional benefits in broad host range interaction, accessing nutrients, phytohormone induction, stress alleviation, biocontrol activity, and eco-friend approach. This study aimed to evaluate the efficacy of PSB isolates coinoculated with compost, bone meal, and DAP fertilizer on tomato growth response. Tomato seeds were treated with 10 selected PSB isolates separately and grown for 20 days on seedbed, then transplanted to field that was treated with external P-sources and enriched by PSB inoculum. PSB isolates showed positive interaction and achieved significant plant assays including plant height, leaves, branches, flowers, and fruit development. Isolate K-10-41 significantly promoted tomato plant height, floral development, and fruit yield, Mk-20-7 enhanced height and fruit weight whereas K-10-27 induced tomato fruit numbers. Compost application promoted tomato-PSB interaction and induced tomato vegetative growth whereas bone meal was least promotor for most of tomato plant assays. Bone meal was however, one of the top fruit development inducers (harvested 20.94 fruits/plant weighing 881.97 gm). Mixing 50% of recommended compost and DAP fertilizer application enhanced tomato vegetative growth and fruit yield (21 fruits/plant harvested that weighed 872.46 gm). Based on the overwhelming performance, K-10-41 and Mk-20-7 application together with compost and fertilizer mixture were found effective. Therefore, the results of this study imply that application of competent PSB isolates together with nutrient supplements improved symbiotic effectiveness, sustainable production, and environmental health. Consequently, these promising isolates would be recommended for tomato production of higher yield and sustainability after verifying their efficacy at different agroecology and taxonomic identification. Screening potential strains and evaluating their competence under different conditions would be the future perspectives to develop efficient inoculants. Moreover, synergetic application of organic supplements (compost, farmyard, bone meal, or other biowastes), bioinoculants, and proper agrochemicals maximize production and environmental health and is feasible for the economic, social, and ecological sense of balance.

“…However, bacterial treatments showed significantly enhanced fresh weight compared to non-treated plants. The study of Khan et al (2022) stated that PSB efficiently enhance fresh weight of plants however, variations in plant fresh weight was observed in the presence of insoluble phosphate treatments with PSB as compared to control (Khan et al 2022). These improvements in various plant morphological traits with the addition of PSB are attributed to their ability of releasing P from insoluble sources to plants under influence of diverse actions adopted by these bacterial stains.…”

Rhizosphere engineering approach is considered a quantum leap in plant sciences. The current study focused on investigating rhizobacterial efficiency to mobilize bioavailable phosphate from insoluble-phosphate source. Phosphate-solubilization potential of four efficient phosphate solubilizing bacterial strains i.e., Pseudomonas songnenensis (GR3), Stutzerimonas stutzeri (HH2), Bacillus bingmayongensis (KH3) and Achromobacter aegrifaciens (MH1) was analyzed. The bacterial strain GR3 was observed as most efficient phosphate solubilizer. Interactions between various physiological parameters and phosphate solubilization efficiency of isolates was evaluated using surface response methodology. In-vitro experiments revealed that glucose significantly facilitated phosphorus solubilization at 37 ℃, with media having pH 7 and 0.5% phosphorous. Additionally, positive correlation among P-solubilization potential, acids produced and pH variations was observed. Plant microbe-interaction analysis was performed to evaluate the efficiency of these bacterial strains on various morpho-physiological responses of Zea mays L. For this purpose, various concentrations of tricalcium phosphate were applied to plants in the presence and absence of bacterial strains. The results showed that, lower phosphate levels trigger shoot development, improve plant weight and leaf formation whereas higher phosphate concentrations stimulated the development of longer root system. The bacterial strains GR3 and HH2 were observed as efficient phosphate-solubilizing bacteria (PSB) that positively stimulated plant morphological responses by triggering various biochemical attributes such as plant protein content, phytohormone homeostasis, macromolecule content, solute content and pigment content. Hence, the current study reviled that the use of these phosphate solubilizing PGPR are efficient phytostimulators used for crop production in replacement of chemical fertilizers which are carcinogenic and deteriorating our eco-system.

“…Diverse microbic inoculums are available and can serve as bio-stimulant enhancing plant development, productivity, and soil fertility 10,11 . Improved soil physical conditions support increased root growth, providing more infection sites for rhizobium, thus enhancing biological nitrogen xation and protein content in legume grains, ultimately improving grain quality 12 . The combined use of bio-fertilizers with chemical fertilizers has been shown to signi cantly boost growth and crop yield 13 .…”

Nitrogen deficiency is a primary factor contributing to reduced crop production in arid and semiarid regions. Addressing this issue requires optimizing soil-plant nitrogen dynamics. In this field experiment, we investigated the impact of organic (farmyard manure) and inorganic (urea) nitrogen sources, both with and without biostimulant (Bioaab), on soil-plant nitrogen dynamics and sustainable maize (Zea mays L.) production in nitrogen-deficient soil. Five different combinations of farmyard manure (FYM) and urea—0:100, 25:75, 50:50, 75:25, and 100:0—were developed and applied with and without Bioaab in a randomized complete block design with a factorial arrangement in triplicate. Organic (FYM) and inorganic (urea) nitrogen sources, whether combined with Bioaab or not, significantly (p < 0.05) improved soil-plant nitrogen content and maize yield. The addition of FYM, whether Bioaab was present or not, had no significant (p > 0.05) impact on yield parameters. In contrast, the application of Bioaab enhanced soil-plant nitrogen dynamics, as indicated by increased plant total nitrogen (1.37%) and total nitrogen uptake (95.7 kg ha− 1) by maize plants, resulting in significantly higher yield compared to non-Bioaab treated plots. However, non-Bioaab treated pots surprisingly recorded maximum soil total nitrogen content (0.057%). Moreover, the plot treated with Bioaab recorded the maximum biomass production (7.99 tons ha− 1), number of grains (2.873 tons ha− 1), and soil organic matter content (1.20%). In conclusion, the use of inorganic fertilizer with a biostimulant (Bioaab) is crucial for improving crop yield and nitrogen release.
