Hasil penelitian ini menunjukkan bahwa perlakuan benih menggunakan rizobakteri jenis Necercia sp dengan kerapatan inokulum 108 cfu/ml nyata meningkatkan vigor benih pada tolok ukur  indeks vigor yaitu 40% dan Pseudomonas capacia dengan kerapatan inokulum 109 cfu/ml juga merupakan kombinasi perlakuan terbaik dalam meningkatkan berat kering kecambah normal yaitu 69,33 mg.Treatment Of Plant Growth Promoting Rhizobacteria (PGPR)With Multiple Levels of Rhizobacteria Inoculum Density On Viability and Vigor Of Expired Red Chilli Seeds (Capsicum annuum L.Abstract. Biological seed treatment is one of the seed treatment using microorganisms such as plant growth-promoting rhizobacteria (PGPR). This study aims to determine the type of rhizobacteria and inoculum density that can increase the viability and vigor of expired chili seeds. This research uses Completely Randomized Design (CRD) factorial pattern with 2 factors and 3 replications. The first factor is the type of rhizobacteria (R) consists of five levels, namely R1: Necercia sp; R2: Bacillus polymixa; R3: Actinobacillus suis; R4: Azotobacter sp; R5: Pseudomonas capacia. The second factor is the density of rhizobacteria inoculum consisting of three levels namely K1: 107 cfu/ml; K2: 108 cfu/ml; K3: 109 cfu/ml. The results of this study showed that the seed treatment using the Necercia sp-type rizobacteria with 108 cfu/ml inoculum density significantly increased the seed vigor on the vigor index benchmark of 40% and Pseudomonas capacia with 109cfu/ml inoculum density was also the best treatment combination in increasing dry weight normal sprout is 69,33 mg.

Plant growth-promoting rhizobacteria with multiple growth-promoting traits play a significant role in soil to improve soil health, crop growth and yield. Recent research studies have focused on the integration of organic amendments with plant growth-promoting rhizobacteria (PGPR) to enhance soil fertility and reduce the hazardous effects of chemical fertilizers. This study aims to evaluate the integrated application of biochar, compost, fruit and vegetable waste, and Bacillus subtilis (SMBL 1) to soil in sole application and in combined form. The study comprises eight treatments—four treatments without inoculation and four treatments with SMBL 1 inoculation in a completely randomized design (CRD), under factorial settings with four replications. The results indicate that the integrated treatments significantly improved okra growth and yield compared with sole applications. The integration of SMBL 1 with biochar showed significant improvements in plant height, root length, leaf chlorophyll a and b, leaf relative water content, fruit weight, diameter and length by 29, 29, 50, 53.3, 4.3, 44.7 and 40.4%, respectively, compared with control. Similarly, fruit N, P and K contents were improved by 33, 52.7 and 25.6% and Fe and Zn in shoot were 37.1 and 35.6%, respectively, compared with control. The results of this study reveal that the integration of SMBL 1 with organic amendments is an effective approach to the sustainable production of okra.

Soil is a dynamic ecosystem which provides support to plant life. Microorganisms inhabiting the rhizosphere region of soil play a key role in agriculture by promoting the exchange of plant nutrients and reducing the application of chemical fertilizers to a large extent. Engineering of rhizospheric region through exploitation of specific microorganisms leads to higher microbial diversity in the soil which in turn plays a significant role in maintaining the soil health. The present work envisages the isolation, screening and biochemical profiling of potent plant growth promoting rhizobacteria from various rhizospheric soils in and around Bangalore. Sixty isolates from rhizospheric region of fourteen different agricultural soils were screened for plant growth promoting traits such as phosphate solubilization, siderophore production, Ammonia, HCN & Phytohormone production. Twelve isolates that exhibited plant growth promotional traits were further subjected to screening for drought and salt tolerance. Among the twelve isolates, four potential isolates namely Serratia marcescens, Pseudomonas aeruginosa and Acinetobacter pittii were identified based on biochemical methods and 16SrRNA sequencing.

Bacteria play a vital role in the quality of soil, health, and the production of plants. This has led to several studies in understanding the diversity and structure in the plant rhizosphere. Over the years, there have been overwhelming advances in molecular biology which have led to the development of omics techniques which utilize RNA, DNA, or proteins as biomolecules; these have been gainfully used in plant–microbe interactions. The bacterial community found in the rhizosphere is known for its colonization around the roots due to availability of nutrients, and composition, and it affects the plant growth directly or indirectly. Metabolic fingerprinting enables a snapshot of the metabolic composition at a given time. We review metabolites with ample information on their benefit to plants and which are found in rhizobacteria such as Pseudomonas spp. and Bacillus spp. Exploring plant-growth-promoting rhizobacteria using omics techniques can be a true success story for agricultural sustainability.
