“…PSM has been widely accepted as an environmentally friendly and easy-to-obtain P fertilizer for increasing soil orthophosphate concentrations and the geochemical P cycle since the early 20th century [41]. PSM produces organic acids and enzymes such as phosphatase and pyrophosphatase which can dissolve P to become available [64,65]. PSM has many roles for plants, including growth boosters [39], biocontrol and bioremediation activities [40], and increasing plant growth and fruit yields [41].…”

In an effort to mitigate the environmental impact of chemical fertilizers while promoting soil sustainability, this study investigated the potential of rhizosphere-associated microorganisms to augment nutrient uptake and growth in melon crops. Soil samples were procured from three distinct melon fields and subjected to serial dilution techniques for microbial isolation on Nutrient Agar (NA) and Potato Dextrose Agar (PDA) media. Subsequent screening identified select isolates with capabilities for nitrogen fixation, phosphorus and potassium solubilization, indole-3-acetic acid (IAA) production, and antagonism against pathogens. Two bacterial isolates, designated BS 1A and BK 1, and one fungal isolate, FW 2B, were earmarked for their plant growth-promoting microorganism (PGPM) potential. Sequence analysis revealed homology of BS 1A with Pseudochrobactrum sp., BK 1 with Bacillus cereus, and FW 2B with Trametes polyzona. A greenhouse experiment employing a completely randomized design evaluated the effects of these isolates on melon growth. Control treatments included a positive control (C+), receiving the recommended dosage of NPK fertilizer, and a negative control (C-), devoid of both NPK and microbial treatments. The application of B. cereus, Pseudochrobactrum sp., and T. polyzona was observed to significantly elevate plant biomass and nutrient acquisition, with B. cereus demonstrating the most pronounced effect, rivalling that of chemical fertilization. The results of this study highlight the potential of utilizing select soil microorganisms as biostimulants, which could play a significant role in increasing the productivity of melon crops, thereby supporting the advancement of sustainable agricultural methodologies.

“…This is because many useful bacteria grow in the rhizosphere soil, one of which is NFB and PSB [4]. The advantage of bacteria in nitrogen fixation is that it increases the efficiency of soil nitrogen, while the advantage of bacteria in phosphate solubility is that it releases phosphate from what was initially unavailable to become available to plants [5,6].…”

Rhizobacteria inhabit the root area of flora and can act as nitrogen fixers and phosphate solvents. This study aims to determine the potential of indigenous dryland rhizobacteria for fixing dissolved nitrogen and phosphate in an artificial medium. Rhizobacteria isolated from rice varieties Inpago 12 and understorey (Eleusine indica L.) have the potential for nitrogen fixation and phosphate solubility. The outcome of morphological observations obtained two types of NFB isolates from each isolate source, while PSB obtained three types of isolates. The highest total NFB population was in the T1J1 isolate at 1.46 x 105 CFU/g, while the highest PSB was in the U2P2 isolate at 8.2 x 104 CFU/g. Further study is needed to determine the potential of rhizobacteria from rice varieties Inpago 12 and understorey (Eleusine indica L.) in dryland for quantitative nitrogen fixation and phosphate solubility.

Phosphate is an essential macro element that has a necessary function as a constituent of ATP and DNA in plants. However, the availability of dissolved phosphate in the soil is minimal because it tends to bind with soil minerals to form phosphate complexes. With rhizosphere fungi, the low available phosphate in the soil can be overcome. This study aimed to determine the character and potential of fungi capable of dissolving phosphate. The source of the isolates used was a collection of rhizosphere fungus isolates under the red jabon stand. Purification was carried out using the point method on PDA media. The phosphate dissolving ability test was done using the standard method using liquid pikovskaya media and then analyzed descriptively and quantitatively. Eighteen rhizosphere fungus isolates were observed, two of which could dissolve phosphate, respectively, obtained from isolates JCS16 with a concentration value of 10.48 ppm, JCS 13 with a concentration value of 10.06 ppm.
