“…This can be seen by reducing the application of synthetic fertilizers by up to 25% to plants inoculated with mycorrhizae [9], thereby reducing the accumulation of chemical fertilizers on agricultural land. The role of mycorrhizae in increasing plant growth and yield as well as in water saving and P dose has been reported by [10,11,12]. Empowerment of mycorrhizae is a very promising alternative to sustainable farming systems and saving natural resources [13,14,15,16].…”

One effort to improve soil fertility and plant productivity is through the inoculation of arbuscular mycorrhizae. Mycorrhizae plays a role in increasing the absorption of phosphorus elements in the soil. The study aimed to determine the effect of the inoculation of arbuscular mycorrhizae on increasing the growth and production of chili. The experiment was carried out in the highlands of West Bandung in 2017-2018. The experimental design used was a randomized completely block design (RCBD) with 5 treatments and 5 replications. The treatments consisted of control, 2 kg/m2 mycorrhizae in the nursery, 4 kg/m2 mycorrhizae in the nursery, 10 g/plant mycorrhizae at transplanting, and 20 g/plant mycorrhizae at transplanting. The mycorrhizae used was Glomus sp. in the form of inoculum (soil as a carrier). Variables observed included soil chemical properties, degree of root infection, vegetative growth, and yield of chili. Data were analyzed using analysis of variance (anova) and continued with Tukey’s Honestly Significantly Difference (Tukey’s HSD) test at 5% significancy level. The results showed that the inoculation of mycorrhizae to andisol on low P soils increased soil P availability, degree of root infection, vegetative growth, and red chili production, but high doses hurt chili yields. The inoculation of mycorrhizae doses of 2 kg/m2 in the nursery and 10 g/plant at transplanting can increase red chili production by 13.19% and 15.59%. To see the effectiveness of mycorrhizae more clearly, it is suggested to test mycorrhizae on chili in the dry season and on marginal soils.

Purpose Arbuscular mycorrhizal fungi (AMF) perform an ancestral and essential association with plant roots, where plants provide carbohydrates and lipids, and the fungi respond by translocating water and nutrients to the roots through the hyphae. There is a need to investigate the microbial community associated with the rhizosphere of mycorrhizal plants in response to the multiple benefits (e.g., improved nutrition and stress resistance) provided by the association. In this work, we analyzed the bacterial communities associated with the rhizosphere of plants and their response to mycorrhizae in low P conditions. Methods For this purpose, inoculated and non-inoculated B73 corn plants were grown with a consortium of mycorrhizal fungi under low phosphorus conditions. Mycorrhiza response in B73 and the interaction with rhizosphere microbiome were characterized by sequencing the bacterial 16S rRNA gene. Results Inoculated plants showed increased greater growth in leaf and root parameters in low P conditions. Bacterial microbiome showed changes in beta diversity and some OUTs significantly regulated by AMF presence. Conclusion These data confirm the importance of mycorrhizae in phosphorus stress and rhizosphere community changes as a possible mechanism to improve plant growth.

In recent decades, numerous studies have examined the effects of climate change on the responses of plants. These studies have primarily examined the effects of solitary stress on plants, neglecting the simultaneous effects of mixed stress, which are anticipated to transpire frequently as a result of the extreme climatic fluctuations. Therefore, this study investigated the impact of applied chitosan on boosting the resistance responses of peanuts to alkali and mixed drought-alkali stresses. Peanuts were grown in mid-alkaline soil and irrigated with full irrigation water requirements (100%IR), represented alkali condition (100% IR × alkali soil) and stress conditions (70% IR × alkali soil—represented mixed drought-alkali conditions). Additionally, the plants were either untreated or treated with foliar chitosan. The study evaluated various plant physio-chemical characteristics, including element contents (leaves and roots), seed yield, and irrigation water use efficiency (IWUE). Plants that experienced solitary alkali stress were found to be more vulnerable. However, chitosan applications were effective for reducing (soil pH and sodium absorption), alongside promoting examined physio-chemical measurements, yield traits, and IWUE. Importantly, when chitosan was applied under alkali conditions, the accumulations of (phosphorus, calcium, iron, manganese, zinc, and copper) in leaves and roots were maximized. Under mixed drought-alkali stresses, the results revealed a reduction in yield, reaching about 5.1 and 5.8% lower than under (100% IR × alkali), in the first and second seasons, respectively. Interestingly, treated plants under mixed drought-alkali stresses with chitosan recorded highest values of relative water content, proline, yield, IWUE, and nutrient uptake of (nitrogen, potassium, and magnesium) as well as the lowest sodium content in leaves and roots. Enhances the accumulation of (N, K, and Mg) instead of (phosphorus, calcium, iron, manganese, zinc, and copper) was the primary plant response to chitosan applications, which averted severe damage caused by mixed drought-alkali conditions, over time. These findings provide a framework of the nutrient homeostasis changes induced by chitosan under mixed stresses. Based on the findings, it is recommended under mixed drought-alkali conditions to treat plants with chitosan. This approach offers a promising perspective for achieving optimal yield with reduced water usage.
