“…Many reports have revealed the positive impact of biostimulants on ornamental production from propagation and planting (El-Serafy 2015; El-Serafy and El-Sheshtawy 2017; Parađiković et al 2017) to postharvest (El-Sheshtawy and El-Serafy 2016; El-Serafy 2019; Hassan and Fetouh 2019), as well as on many horticulture crops (El-Serafy 2018;Ahmad et al 2019;Stamford et al 2019;El-Serafy and El-Sheshtawy 2020). Chitosan is a form of deacetylated chitin, obtained from the outer shell of Crustacea, such as crabs, krills, or shrimps (Sandford and Hutchings 1987), and found also in insects cuticle and fungi cell walls.…”

Cordyline is one of the most important indoor pot plants and has a high request in the global market. As a bio-stimulant, chitosan could be used to enhance the plant growth and productivity, despite the variation in growth analysis and phenotypic plasticity of several plant species in response to chitosan supplement. Cordyline seedlings were foliar sprayed with five concentrations of oligo-chitosan (0, 25, 50, 75, and 100 mg L −1) for 4 months. Oligo-chitosan induced rapid growth of cordyline seedlings, in terms of larger specific leaf weight (SLW) and higher relative growth rate (RGR A), as well as improving the efficiency of plant photosynthesis (high net assimilation rate (NAR) or low specific leaf area (SLA)). Root growth rate (RGR R) has also increased by 89.13% with the application of 50 mg L −1 oligo-chitosan, which reflected on higher plant biomass (BM) in comparison to the control. Consequently, root biomass (RM) showed the greatest plasticity index (PPI) that enhanced growth, productivity, and quality as well as the marketability of cordyline seedlings. Foliar spray of 50 mg L −1 oligo-chitosan improved plant growth, root development, and plasticity index, resulted in increased quality and marketability of cordyline seedlings.

“…The suitability of organic matter to finetune the nutrient supply to the crop requirement is characterized by the fast N availability provided (Tei et al, 2020). Biofertilizer was also recommended for providing N nutrient in lettuce grown in a Ultisol (Stamford et al, 2019).…”

Rorippa indica L. Hiern is a local vegetable that is widely consumed by Dayak’s tribe in Central Kalimantan, Indonesia. It is mostly traditionally cultivated without fertilizers, resulting in low productivity. The research aimed to investigate the effect of fertilizers and soil type on the growth characteristics and N uptake of R. indica. The experiment was arranged in a factorial completely randomized design consisting of two factors with four replications. The first factor was fertilizer application (control, 20 t ha-1 of chicken manure, and 600 kg ha-1 of NPK), and the second was soil type (peat and Ultisol). The results revealed that the interaction of fertilizers and soil type gave a non-significant effect on all variables observed, except N uptake. The application of NPK increased the plant height and number of leaves significantly. Compared to control, the increment was 112.50% and 130.32%, respectively, and chicken manure application increased the dry weight (327.87%), N total (310.16%), and N uptake of plants by 478% in peat soil and 228% in Ultisol. This finding concludes that 20 t ha-1 of chicken manure can be applied to increase the productivity of R. indica.

“…In recent times, there has been a growing interest in finding substitutes for chemical fertilisers in order to address their adverse impact [4,5]. Microbial fertilisers have emerged as a promising alternative for organic and sustainable agriculture, garnering significant attention in fertiliser research [6][7][8]. Numerous studies have demonstrated that the use of microbial fertilisers can enhance soil organic carbon content, promote soil enzyme activity, increase fertiliser utilisation, stimulate crop growth, and impact the structural and functional diversity of soil microbial communities [9][10][11][12].…”

(1) Background: Low-calcium stress can have adverse effects on the rhizosphere environment of cucumber, subsequently impacting cucumber growth. However, plant-growth-promoting rhizobacteria can directly or indirectly enhance plant growth and induce plant tolerance, thereby mitigating the detrimental effects of low-calcium stress on cucumber growth. This study aims to elucidate the role of Bacillus amyloliquefaciens QST713 in the rhizosphere environment of cucumber under low-calcium stress, providing a theoretical basis for the application and promotion of Bacillus amyloliquefaciens. (2) Methods: This study used the ‘JinYou NO.4′ cucumber variety as test material, setting four treatments of CK, CK+Q, LCa, LCa+Q. We conducted measurements of plant height and stem diameter for four groups of cucumber plants: before treatment (0 d), and at 10 d, 20 d, 30 d, and 60 d after treatment. Additionally, we determined the biomass of cucumber plants under different treatments during the peak fruiting period. Inter-root matrix samples of cucumber were collected during the fruiting late period, and the physical and chemical properties and nutrient contents of the inter-root matrix of cucumber were determined, and bacterial microbial diversity and bacterial microbial communities were analysed using Illumina-MiSeq high-throughput sequencing technology. (3) Results: Low-calcium stress significantly inhibits the growth of cucumber plants. However, the application of Bacillus amyloliquefaciens QST713 effectively mitigates the inhibitory effects of low-calcium stress on cucumber growth. The application of Bacillus amyloliquefaciens QST713 was able to improve the physicochemical environment of the matrix and enhanced the absorption and utilisation of matrix nutrients in cucumber. The high-throughput sequencing analysis showed that the richness and diversity of bacterial communities and the number of bacteria decreased significantly under low-calcium stress, and increased significantly after the application of Bacillus amyloliquefaciens QST713. The composition of the dominant bacterial groups of the inter-root matrix of cucumber was basically the same among the four treatments, and the main difference was in the abundance of bacteria. The application of Bacillus amyloliquefaciens QST713 increased the relative abundance of bacteria that decreased under low-calcium stress, and decreased the relative abundance of bacteria that increased under low-calcium stress. (4) Conclusions: The results of this study elucidated the positive effects of Bacillus amyloliquefaciens QST713 on the growth and inter-root environment of cucumber under low-calcium stress, and provided a theoretical basis for in-depth research on the resistance of Bacillus amyloliquefaciens and its popularised application.
