Published: May 15, 2024

Abstract Fertilizers application are widely used to get a higher yield in agricultural fields. Nutrient management can be improved by cultivating leguminous species order obtain better understanding of the mechanisms that increase amount available phosphorus (P) and potassium (K) through fertilizer treatments. A pot experiment was conducted identify (i.e., chickpea pea) under various Experimental design is as follows: T0 (control: no applied), T1: P applied at level (90 kg ha −1 ), T2: (K 90 T3: (PK both ). All treatments significantly ( p < 0.05) nutrient accumulation abilities enzymes activities. The T3 treatment showed highest N uptake 37.0%, compared T0. While developed greater pea 151.4% than control. However, also increased microbial biomass i.e., 95.7% 81.5% chickpeas peas, respectively, treatment. In chickpeas, T1 stimulated NAGase activities 52.4%, T2 URase 50.1% contrast, enhanced BGase Phase enzyme activities, 55.8% 33.9%, Only 149.7%, 111.9%, 81.1%, 70.0%) Therefore, adding combined K applications soil activity legume species, changes availability make it easier for plants nutrients.

A plant’s perception of growth-promoting bacteria and their metabolites

Frontiers in Plant Science, Journal Year: 2024, Volume and Issue: 14

Many recent studies have highlighted the importance of plant growth-promoting (rhizo)bacteria (PGPR) in supporting plant’s development, particularly under biotic and abiotic stress. Most focus on traits selected strains latter’s effect biomass, root architecture, leaf area, specific metabolite accumulation. Regarding energy balance, growth is outcome an input (photosynthesis) several outputs (i.e., respiration, exudation, shedding, herbivory), frequently neglected classical PGPR-plant interaction. Here, we discuss primary evidence underlying modifications triggered by PGPR their metabolites ecophysiology. We propose to detect PGPR-induced variations photosynthetic activity using gas exchange recommend setting up correct timing for monitoring responses according objectives experiment. This research identifies challenges tries provide future directions scientists working interactions exploit potential microorganisms’ application improving value.

Abstract Soil pollution with heavy metals has grown to be a big hassle, leading the loss in farming production particularly developing countries like Pakistan, where no proper channel is present for irrigation and extraction of these toxic metals. The study aims ameliorate damages caused by metal ions (Hg-Mercury) on rapeseed ( Brassica napus L.) via growth regulator (α-tocopherol 150 mg/L) thermopriming technique at 4 °C 50 maintain plant agronomical physiological characteristics.

Abstract With global phosphate rock resources declining for conventional fertilizers, there is growing interest in exploring alternative, more sustainable materials to enhance soil fertility and crop yield production. Additionally, leveraging microorganisms improve phosphorus (P) availability soils an appealing approach agriculture. This study evaluates the effects of different P-rich materials, including struvite (STRU), meat bone meal (MBM), (PR), combined with a microbial consortium P-solubilizing plant growth-promoting capabilities, on P growth two contrasting physicochemical properties. To achieve these goals, pot experiment was conducted assess content soil, ryegrass, biomass, along enzyme activity community composition using fatty acid analysis. The involved characteristics, amended monoammonium (CHEM), STRU, MBM, PR, or without inoculation. Soil characteristics type fertilizer significantly influenced availability, ryegrass uptake, yield. Microbial inoculation did not increase Fatty analysis showed changes fertilizer. Struvite performed similarly CHEM, while MBM less effective than but better PR as Our found that affected dynamics soil–plant system. Recycled P-based fertilizers offer alternatives synthetic ones, potentially alleviating agricultural challenges.
