The application of chemical fertilizers for plant growth and protection is one the reasons environment ecosystem destruction, thus, sustainable agriculture gaining popularity in research among farming communities. Although most soils are high total phosphorus (P), a large portion unavailable to plants regarded as growth-limiting factor. P-solubilizing bacteria (PSB) exploitation newly developed bio-solution enhancing rhizosphere P availability; however, effect these on soil quality different phases remains unknown. This study aims evaluate impact five strains PSB, isolated from legume rhizosphere, two (Vicia faba Pisum sativum) certain properties. efficient PSB used characterized by P-solubilization, ACC deaminase activity, fixation N, IAA, HCN, siderophores production. activity tested vitro vivo under controlled conditions supplemented with rock (RP). According our findings, all PSBs outperformed control terms legumes percentage ranging 77.78 88.88%, respectively. results showed that treatments significantly improved parameters like nitrogen- (N) P-content (67.50, 23.11%), Also, an increase fresh dry weights above- (41.17, 38.57%) below-ground biomasses (56.6, 42.28%), Compared control, this leads 72% root length, 40.91% weight, 40.07% weight. Rhizospheric displayed levels P, organic matter. All were found have higher alkaline phosphatase, basal respiration, β-glucosidase than control. It concluded multi-traits can be alternative utilizing enhance growth. Despite potency PSBs, its use source development implies focusing crop species adaptation, stress tolerance climate resilience.

Enhancing sustainable crop production through integrated nutrient management: a focus on vermicompost, bio-enriched rock phosphate, and inorganic fertilisers – a systematic review

Frontiers in Agronomy, Год журнала: 2024, Номер 6

Опубликована: Авг. 6, 2024

Securing a consistent food supply remains pressing global challenge, particularly for small-scale farmers grappling with obstacles in enhancing agricultural yields, especially tropical soils. Integrated Nutrient Management (INM) techniques, employing organic manures like vermicompost and bio-enriched rock phosphate, emerge as recommended solutions. Vermicompost is lauded its nutrient richness positive soil health impacts. At the same time, phosphate serves sustainable alternative to conventional phosphorus fertilisers, specifically tailored conditions. Despite individual studies assessing effects of vermicompost, soluble fertilisers on plant growth, comprehensive overview their combined application noticeably lacking. To fill this gap, study employs Preferred Reporting Items Systematic Review Meta-Analysis (PRISMA) method explore synergies combining these elements impacts crop production environment. This review among first comprehensively summarize complexities chemical various crops. It thoroughly examines potential advantages, disadvantages, systems, socio-economic implications, existing policies governing usage. Our findings reveal that leads significant improvements yield, properties. The optimal impact observed when constitutes 25% fertiliser comprises 75 or 100% dosage. Moreover, incorporating mixture phosphate-solubilizing bacteria (PSB) strains further enhances effects. findings, we identified gaps approaches addressing socio-cultural dimensions lack literature prevailing regarding use systems highlighting need more holistic understanding incorporation better grasp institutional frameworks guiding practices. However, secure production, integrate biofertilisers fertilisers. In fostering adoption inclusive practices small rural properties, it advisable incorporate education into farmer training programs.
