“…[ 112 ]. Some studies applied GA and auxin—combined with the use of an aeroponic system—to improve potato yield [ 113 , 114 ]. Integrations of different soilless system designs and PGPB functions may be useful in expanding the range of feasible crops for soilless agriculture.…”

In this literature review, we discuss the various functions of beneficial plant bacteria in improving plant nutrition, the defense against biotic and abiotic stress, and hormonal regulation. We also review the recent research on rhizophagy, a nutrient scavenging mechanism in which bacteria enter and exit root cells on a cyclical basis. These concepts are covered in the contexts of soil agriculture and controlled environment agriculture, and they are also used in vertical farming systems. Vertical farming—its advantages and disadvantages over soil agriculture, and the various climatic factors in controlled environment agriculture—is also discussed in relation to plant–bacterial relationships. The different factors under grower control, such as choice of substrate, oxygenation rates, temperature, light, and CO2 supplementation, may influence plant–bacterial interactions in unintended ways. Understanding the specific effects of these environmental factors may inform the best cultural practices and further elucidate the mechanisms by which beneficial bacteria promote plant growth.

“…Currently, a combination of three bacterial inoculants ( Azospirillum lipoform , Pseudomonas putida , Aztobacter crococum ), and chemical fertilizer nutrition in an aeroponic culture system is the most important factor for the quantitative and qualitative production of healthy potato seeds ( Nasiri et al, 2022 ). The combination bacterial formulation (BF) containing strains of A. chroococcum, A. lipoferum and P. putida has the potential to increase the tuber yield of potato in healthy soil as well as in the soil infested with N. rubicola ( Riaz et al, 2022 ).…”

Potato (Solanum tuberosum L.) is one of the most important crops in maintaining global food security. Plant stand and yield are affected by production technology, climate, soil type, and biotic factors such as insects and diseases. Numerous fungal diseases including Neocosmospora rubicola, causing stem rot, are known to have negative effects on potato growth and yield quality. The pathogen is known to stunt growth and cause leaf yellowing with grayish-black stems. The infectivity of N. rubicola across a number of crops indicates the need to search for appropriate management approaches. Synthetic pesticides application is a major method to mitigate almost all potato diseases at this time. However, these pesticides significantly contribute to environmental damage and continuous use leads to pesticide resistance by pathogens. Consumers interest in organic products have influenced agronomists to shift toward the use of biologicals in controlling most pathogens, including N. rubicola. This review is an initial effort to carefully examine current and alternative approaches to control N. rubicola that are both environmentally safe and ecologically sound. Therefore, this review aims to draw attention to the N. rubicola distribution and symptomatology, and sustainable management strategies for potato stem rot disease. Applications of plant growth promoting bacteria (PGPB) as bioformulations with synthetic fertilizers have the potential to increase the tuber yield in both healthy and N. rubicola infested soils. Phosphorus and nitrogen applications along with the PGPB can improve plants uptake efficiency and reduce infestation of pathogen leading to increased yield. Therefore, to control N. rubicola infestation, with maximum tuber yield benefits, a pre-application of the biofertilizer is shown as a better option, based on the most recent studies. With the current limited information on the disease, precise screening of the available resistant potato cultivars, developing molecular markers for resistance genes against N. rubicola will assist to reduce spread and virulence of the pathogen.

The potato is a horticultural commodity with a high economic value and a consistent selling price. Indonesian potato production, however, remains lower than that of other Asian countries. One reason for this is that environmental sustainability has influenced the expansion of potato cultivation on a plateau, so medium plains have become an alternative. Aside from high-quality seeds, using plant growth-promoting rhizobacteria (PGPR) and Trichoderma sp. as an organic fertilizer is a strategic effort to boost potato yields on medium plains. The focus of this research was to examine how PGPR and Trichoderma sp. affect the growth of potatoes on medium plains. This study was carried out in Temanggung and Sawangan, Magelang, Jawa Tengah, at an altitude of 480 m.a.s.l, using the a complete random design with four different treatments: P0 = control, Treatment P1 = PGPR 20 ml/10 liter water, Treatment P2 = PGPR 40 ml/10 liter water, Treatment P3 = Trichoderma 80 gram/10 liter water, Treatment P4 = Trichoderma 150 gram/10 liter water, and Treatment P5 = PGPR 20 ml/10 liter water + Trichoderma 80 gram/10 liter water. The study found that a combination of PGPR and Trichoderma sp. treatment resulted in better growth than a single PGPR treatment. Keywords: biopesticide, organic fertilizer, PGPR
