“…Although some studies have reported no marked yield reduction in continuous wheat cropping [30], substantial investigations have revealed that the yield of wheat and barley decreased after continuous cropping in different regions [31,32]. Furthermore, there are various reasons for decreases in crop yield under continuous cropping, such as broken soil-micro-organism balance, deterioration of soil nutrients, and accumulated viruses resulting in plant diseases [33][34][35]. However, a systematic survey on redox regulation associated with continuous cropping has been neglected during past decades, involving the simple measurement of antioxidant enzymes such as SOD and CAT [27,36].…”

Continuous spring cropping of Qingke (Hordeum viilgare L. var. nudum Hook. f.) results in a reduction in grain yield in the Xizang autonomous region. However, knowledge on the influence of continuous cropping on grain yield caused by reactive oxygen species (ROS)-induced stress remains scarce. A systematic comparison of the antioxidant defensive profile at seedling, tillering, jointing, flowering, and filling stages (T1 to T5) of Qingke was conducted based on a field experiment including 23-year continuous cropping (23y-CC) and control (the first year planted) treatments. The results reveal that the grain yield and superoxide anion (SOA) level under 23y-CC were significantly decreased (by 38.67% and 36.47%), when compared to the control. The hydrogen peroxide content under 23y-CC was 8.69% higher on average than under the control in the early growth stages. The higher ROS level under 23y-CC resulted in membrane lipid peroxidation (LPO) and accumulation of malondialdehyde (MDA) at later stages, with an average increment of 29.67% and 3.77 times higher than that in control plants. Qingke plants accumulated more hydrogen peroxide at early developmental stages due to the partial conversion of SOA by glutathione (GSH) and superoxide dismutase (SOD) and other production pathways, such as the glucose oxidase (GOD) and polyamine oxidase (PAO) pathways. The reduced regeneration ability due to the high oxidized glutathione (GSSG) to GSH ratio resulted in GSH deficiency while the reduction in L-galactono-1,4-lactone dehydrogenase (GalLDH) activity in the AsA biosynthesis pathway, higher enzymatic activities (including ascorbate peroxidase, APX; and ascorbate oxidase, AAO), and lower activities of monodehydroascorbate reductase (MDHAR) all led to a lower AsA content under continuous cropping. The lower antioxidant capacity due to lower contents of antioxidants such as flavonoids and tannins, detected through both physiological measurement and metabolomics analysis, further deteriorated the growth of Qingke through ROS stress under continuous cropping. Our results provide new insights into the manner in which ROS stress regulates grain yield in the context of continuous Qingke cropping.

“…Studies have found those organic fertilizers made from poultry manure are rich in a variety of organic acids, peptides, and rich nutrients including nitrogen, phosphorus, and potassium, thus are able to provide micronutrients for crop growth [4], alleviate soil acidification and improve soil quality [5,6]. Zheng et al found that long-term application of organic fertilizer was beneficial to the improvement of soil conductivity, and significantly increased the activities of Cu, Zn, Fe, Mn, Ca, Mg, macronutrients, available nutrients, and enzymes [7]. Qaswar et al found that the application of organic fertilizer could increase the total amount of soil nutrients such as SOM, total nitrogen (TN), and total phosphorus (TP), and also increase the content of available nutrients -Alkali hydrolyzed nitrogen (AN), available phosphorus (AP), and available potassium (AK) in soil [8].…”

BackgroundReductive soil disinfestation (RSD), which involves creating anaerobic conditions and incorporating large amounts of organic materials into the soil, has been identified as a reliable strategy for reducing soilborne diseases in successive cropping systems. However, limited research exists on the connections between soil microorganism composition and plant diseases under various types of organic material applications. This study aimed to evaluate the effects of distinct RSD strategies (control without soil amendment; RSD with 1500 kg ha−1 molasses powder; RSD with 3000 kg ha−1 molasses powder; RSD with 3000 kg ha−1 molasses powder and 37.5–41.3 kg ha−1 microbial agent) on the plant disease index, bacterial community composition and network structure in rhizosphere soil.ResultsRSD treatments significantly reduced the occurrence of black shank disease in tobacco and increased soil bacterial diversity. High amounts of molasses powder in RSD treatments further enhanced disease inhibition and reduced fungal abundance and Shannon index. RSD also increased the relative abundance of bacterial phylum Firmicutes and fungal phylum Ascomycota, while decreasing the relative abundance of bacterial phyla Chloroflexi and Acidobacteriota and fungal phylum Basidiomycota in rhizosphere soil. A multiple regression model identified bacterial positive cohesion as the primary factor influencing the plant disease index, with a greater impact than bacterial negative cohesion and community stability. The competition among beneficial bacteria for creating a healthy rhizosphere environment is likely a key factor in the success of RSD in reducing plant disease risk.ConclusionRSD, especially with higher rates of molasses powder, is a viable strategy for controlling black shank disease in tobacco and promoting soil health by fostering beneficial microbial communities. This study provides guidelines for soil management and plant disease prevention. © 2024 Society of Chemical Industry.
