Water stress decreases the health and quality of horticulture crops by inhibiting photosynthesis, transpiration, and nutrient uptake. Application of plant growth promoting rhizobacteria (PGPR) can increase the growth, stress tolerance, and overall quality of field and greenhouse grown crops subjected to water stress. Here, we evaluated Serratia plymuthica MBSA-MJ1 for its ability to increase plant growth and quality of Petunia × hybrida (petunia), Impatiens walleriana (impatiens), and Viola × wittrockiana (pansy) plants recovering from severe water stress. Plants were treated weekly with inoculum of MBSA-MJ1, and plant growth and quality were evaluated 2 weeks after recovery from water stress. Application of S. plymuthica MBSA-MJ1 increased the visual quality and shoot biomass of petunia and impatiens and increased the flower number of petunia after recovery from water stress. In addition, in vitro characterizations showed that MBSA-MJ1 is a motile bacterium with moderate levels of antibiotic resistance that can withstand osmotic stress. Further, comprehensive genomic analyses identified genes putatively involved in bacterial osmotic and oxidative stress responses and the synthesis of osmoprotectants and vitamins that could potentially be involved in increasing plant water stress tolerance. This work provides a better understanding of potential mechanisms involved in beneficial plant-microbe interactions under abiotic stress using a novel S. plymuthica strain as a model.

The low productivity of cocoa plantations in Indonesia is partly due to the low quality of seeds, which refers to the impeded growth of cultivated cocoa nurseries. Seed is the initial growth of plants so the importance of giving special treatment to seeds will refer to better seed growth. Provision of Plant Growth Promoting Rhizobacteria (PGPR) microbes can produce indoleacetic acid (IAA) in plants to improve the quality of plant growth. This study aims to determine the effectiveness of the provision of Plant Growth Promoting Rhizobacteria bamboo rhizosphere against cocoa seed germination. The study was carried out in the farmer group garden, Gantarangkeke District, Bantaeng. This study was arranged in the form of a two-factor factorial design (F2F) in a randomized block design (RBD). The use of cocoa seed type as the first factor consisted of GTB (Gantarangkeke Bantaeng) local cocoa seed and MCC 01 cocoa seed and seed immersion treatment at PGPR rhizosphere bamboo concentration as the second factor consisting of 0% (control) concentration, 5%, 10 % and 15%. The results obtained indicate that administration of seeds with bamboo rhizosphere PGPR affects the germination (100.00%), the speed of seed growth (7.14%/etmal), as well as on abnormal seeds (10.00%). So that the provision of bamboo rhizosphere PGPR on cocoa seeds has an effective influence on seed germination and cocoa seedling development.

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.

<p>To initiate the decomposition process need decomposer inoculants and an easily available nutrient as C sources (sugar, carbohydrate) and N sources (protein, N inorganic fertilizer). Fresh organic materials are suitable sources for all nutrient needed. Cattle manure or Urea is important N sources for the initiation of composting process. Charcoal – Ash is referring the entire remnants of a wood/bamboo burning fire. In reality, what remains after a typical fire in a bamboo or wood burning stove or fireplace is both ash and charcoal. Both ash and charcoal can offer tremendous benefits to the compost and garden soil. In order to enhance the decomposition processes and its quality of compost, addition of other valuable materials are necessary. Therefore preliminary study of synergy of biochar for composting was conducted. The field experiments were conducted in Terantang village, Sampit-Central Kalimantan and laboratory analysis were conducted in the laboratory of ecology and physiology of microorganisms, Reserach Center for Biology Cibinong. The parameters measured were the number of plant growth promoting rhizobacteria after composting and the C/N ratio of the compost. Those all parameters were compared with natural composting (control). The significant higher number of PGPR and better quality of final compost of treated biochar were observed. In this paper, more detail the effect of biochar on composting, its quality of compost and their effect on sorghum nursery will be discussed. </p><p><strong>Keywords</strong>: biochar, compost, plant growth promoting rhizobacteria, sorghum</p>

The introduction of the “Farm to Fork” strategy in the EU will require a significant reduction in mineral nitrogen fertilization, and therefore the introduction of innovative production technologies to prevent a decline in agricultural production. Studies carried out in several locations in Poland in 2016/17–2018/2019 tested the possibility of replacing 30% of the dose of mineral nitrogen with growth activators alone, in combination with plant growth promoting rhizobacteria in the cultivation of winter wheat. It was confirmed that these two combinations allowed the obtention of a higher yield of grain by 13%, compared to the full nitrogen dose. Simultaneously, the grain quality did not change significantly. In some locations, a decrease in the content of nitrates in the soil was observed, which may mean a greater uptake of this nutrient by plants and an increase in the content of some available macro- and micro-elements, mainly phosphorus, magnesium, zinc, copper and iron, and soil organic carbon. Introducing the studied treatment and limiting the fertilization with mineral nitrogen of wheat in Poland by only 30 kg ha−1 N would save its consumption by 72 thousand t per year.

Irrigation Treatments

Chlorophyll fluorescence was measured of H1015 tomato hybrid with different bacterial treatments (B0–B1–B2–B3) and three irrigation treatments: regular irrigated (RI), deficit irrigated (DI) and non-irrigated conditions (I0). The aim of the experiments was to show the effects of plant growth promoting rhizobacteria on the yield, dry matter and vitamin C content of processing tomato during different irrigation treatments, and measuring the chlorophyll fluorescence during the ripening and development stages. According to the results, none of the bacterial treatments had a statistical effect on the quantity and quality of the tomato and on the chlorophyll fluorescence, only the irrigation. Further studies are needed.
