Thus, this study aimed to evaluate the agronomic performance of the common bean inoculated with a phosphate-solubilizing inoculant under different growing seasons and edaphoclimatic conditions.Four field experiments, carried out in three different locations, in two growing seasons within two consecutive agricultural years, were addressed to a randomized block design with five replicates and seven treatments, including: Absolute control (AC), 50% phosphate fertilization (AF50B0), full-dose phosphate fertilization (AF100B0), and four treatments with different doses of the phosphate-solubilizing inoculant in combination with 50% phosphate fertilization, namely 1 mL (AF50B1), 2 mL (AF50B2), 3 mL (AF50B3), and 4 mL (AF50B4) per kg of seeds. Root and shoot development, yield components, P accumulation in grains, and productivity were determined. The phosphate-solubilizing inoculated treatments showed significant effects on the evaluated parameters, with AF50B4 standing out as a significant influence on growth and production parameters. In general, P accumulation in grains on AF50B4 was greater than that of the AF100B0 treatment. In terms of productivity, across the four locations, the AF50B4 treatment yielded 4,111 kg ha^-1, compared to 3,496 kg ha^-1 in the AF100B0 treatment, representing a 17.6% increase.

A field study was conducted during 2015 and 2016 at Indian Council of Agricultural Research - Central Research Institute for Dryland Agriculture (ICAR-CRIDA), India to evaluate root dynamics of Drought Tolerant (DTV) and Drought Susceptible (DSV) varieties of mung bean under Organic Amendment at the rate of 3 t ha^-1 (OA), resource conservation measure (in-situ Conservation Furrow for every three rows of the crop) as RCM, the combination RCM + OA under normal and deficit rainfall conditions. An innovative field root architectural sampling was followed to extract roots from different soil depths with minimal root losses. RCM increased the rooting depth by 5 cm while OA increased root length density (RLD). Together these measures improved root plasticity as early increased root length, high RLD at deeper soil depths (≥ 0.5 cm cm^− 3), and fine roots of &lt; 1.08 mm diameter in the drought-tolerant mung bean cultivar. The estimated potential carbon additions of mung bean root to soil is 7.1–16.3 kg ha^− 1 for a single crop.

Microbial phytohormones and vitamins are safe, eco-friendly, and effective natural solutions to increase the crop's productivity and maintain the soil health at the same time. To our knowledge, until know there is no information about the roles of microbial gibberellic acid (GA₃), and vitamins on the growth and quality traits of onions. Two field experiments were conducted during two consecutive winter seasons in a sandy calcareous soil farm. Two treatments were in the main plot (without and with microbial GA₃), and six were in the sub-plot (control, chemical thiamine, ascorbic acid, riboflavin, and microbial ascorbic acid and riboflavin). Plant growth parameters including plant height, fresh weight, leaf number, bulb diameter, and neck diameter were recorded. Onion yield and their quality traits of sugar content, protein, antioxidants, vitamin C, phenols, flavonoids, and NPK were measured. The major findings revealed that plants treated with applications of microbial GA₃ or vitamin treatments significantly improved the onion yield, phenotypic, physiological, and biochemical characteristics in both seasons. In the majority of the measured parameters, the microbial ascorbic acid treatment outperformed the other vitamin treatments. The combination of foliar microbial GA₃ spray and vitamins, especially microbial ascorbic acid, and microbial riboflavin, produced the high onion yield, growth and quality traits of plant height, number of leaves, fresh weights, bulb diameter, sugar content, vitamin C, total antioxidants, total phenols, and flavonoids during both seasons.

Methods: These goals were achieved through (i) a histochemical study of Cd localization in pea roots, (ii) spectrophotometric determination of pectin content and the activity of pectin methylesterase (PME), (iii) speciation of Cd extracted from pea roots conducted through size exclusion chromatography (SEC) and inductively coupled plasma mass spectrometry (ICP/MS). Results: Cd was found mainly in the root stele of the Cd-stressed plants. The pectin content and PME activity were lower in the Cd-stressed plants, but Si supplementation reversed these effects. Selectivity was noticed in Cd extraction efficiency with water being the least effective and enzymatic-assisted extraction proving to be the most effective. Speciation analysis revealed significant heterogeneity in molar mass, ranging from approximately 295 to 95 kDa. Galacturonic acid was identified the dominant species responsible for Cd binding. The choice of solvent for extraction markedly influenced the Cd binding profile, indicating shifts in the distribution of species’ molar mass and their relative concentrations in extracts. Conclusions: Si alleviates Cd toxicity in pea plants, and one of the mechanisms through which it operates involves increasing pectin levels and PME activity.

Biochar, containing various elements such as carbon, nitrogen, and phosphorus, possesses a porous structure with strong adsorption capabilities. This characteristic renders it useful for ameliorating acidic soils, influencing soil nitrogen cycling, and mitigating greenhouse gas emissions. To quantitatively analyze the diverse impacts of different biochar on soil nitrogen cycling and to highlight its implications for sustainable agriculture, this study collected 155 relevant articles and conducted a comprehensive meta-analysis. The results indicate that biochar can elevate the pH by 4.60% for acidic soils and significantly increase soil organic carbon content by 64.60%. Different feedstocks, such as Wooden Biochar (WB), Crop Husk (CH) Biochar, Crop Straw Biochar (CS), and Organic Waste Biochar (OW), exhibit distinct effects, with WB and OW showing the most significant increases in SOC. Pyrolysis temperature is also a critical factor, and biochar produced at medium and high temperatures enhances pH more effectively than low-temperature biochar. Additionally, biochar enhances the abundance of the nitrogen functional gene <i>amoA-</i>AOB by 25.58%, promoting ammonia oxidation, reducing ammonia (NH₃) emissions by 16.39%. Experimental setups also influence outcomes that biochar application in woods and incubation studies significantly reduced nitrous oxide (N₂O) emissions compared to pot and field experiments. The findings suggest that adding biochar to soil accelerates nitrogen cycling, thereby reducing greenhouse gas emissions.

Investigate the effects of alternative phosphorus fertilizers on the phosphorus use efficiency of maize over two consecutive cropping cycles. Determine the feasibility of these alternative phosphorus sources as replacements for conventional TSP to promote sustainable nutrient management practices in agriculture. In a greenhouse, sandy loam and clayey soils were fertilized with four P sources: OM, Est, ThermoP, and TSP. Two successive maize crops were grown, with each treatment receiving a P rate of 100 mg kg^− 1. Soil and plant chemical analyses were carried out and then the following fertilizer efficiency indices were calculated: agronomic efficiency index (AEI), agronomic efficiency (AE), crop recovery efficiency (CE), phosphorus utilization efficiency (PUE), P recovery efficiency (PUpE), and physiological efficiency (PE). Est and OM had higher agronomic efficiencies than TSP in sandy soils. The alternative sources exhibited almost 2-fold more efficiency in the sandy loam compared to the clayey soil. The superior performance of Est was attributed to its slow nutrient release and physicochemical properties that potentially improve soil quality. Regarding PE, OM and TSP led the highest values in both cultivations in sandy loam soil. In the 1st crop cycle, the average PE of these two treatments was ∼ 215 g g^− 1 while in the 2nd the average was ∼ 181 g g^− 1. The Est fertilizer resulted in the highest values of CE, PUpE, and PUE.
