“…Many recent reports on IDM focus on related-topics such as ecological drought (Sadiqi et al 2022) and assessing drought vulnerability for water resources management, e.g., in Central India (Thomas et al 2022), Bangladesh (Islam et al 2023), and Iran (Jalili et al 2023). Some studies have focused on multiple uncertainties (Wang et al 2023a), hydro-systems and cities (de Assis Souza Filho et al 2023), or food (Alves et al 2023), This IDM approach can involve application of materials for mitigation of drought such as addition of nutrients including silicon (Si), potassium nitrate (KNO 3 -) (Alam et al 2023), methyl jasmonate and potassium (Beigi et al (2023), or biochar and methyl jasmonate (Nasiri et al 2023).…”

NGOING climate change is leading to more extreme weather, which affects agriculture in various ways. In semi-arid regions of the world, and even some humid areas, drought stress is becoming more frequent. Prolonged drought periods lead to severe damages to cultivated plants, which impacts water and food resources. This review investigates how drought stress impacts plants and how management practices can be utilized to reduce the negative effects. Special attention is given to nano-farming where application of nanomaterials may ameliorate drought stress by increasing enzymatic antioxidants and decreasing generation of reactive oxygen species (ROS). Despite the promising results of nano-farming we conclude that further research is required, particularly to investigate potential negative effects, for example on nano-toxicity where particles can enter groundwater or into the food chain. Finally, drought stress is a complexed problem that affects all living organisms. A quick fix is not possible, but humankind needs to collaborate and work for a better future for all.

Potassium (K) is an essential macronutrient that determines crop productivity and promotes crop growth under conditions of abiotic stress. In this review paper, peer‐reviewed publications (experimental data) dealing with the role of K administration in the control of cereals growth under drought stress are reviewed and analyzed. Most published research on the impact of K administration on cereals growth under drought focuses primarily on bread wheat (Triticum aestivum L.) and maize (Zea mays L.), along with barley (Hordeum vulgare L.), rice (Oryza sativa L.), pearl millet (Pennisetum glaucum L.), and sorghum (Sorghum bicolor L.). The beneficial effect of K on cereals growth under drought has been related to maintenance of water balance in the crops, increased activity of the antioxidant enzymes, increased synthesis of osmolytes, contribution to a low sodium (Na)/K ratio, extension of the grain filling period, and increase of the grain growth rate and weight. Moreover, K was suggested as a possible way for enhancing nitrogen use efficiency (e.g., bread wheat and sorghum). Nevertheless, the beneficial effect of foliar applied K in dried soil during grain filling differed among bread wheat cultivars, highlighting that the effect of K supply on grain weight may differ depending on application method, that is, administration through the soil or the foliage. Overall, K supply could be exploited as a tool for increasing cereal tolerance to drought, for example, by considering late administration of K through top dressing applications or foliar sprayings. Yet additional information is needed on the rate and the K form, along with the most suitable growth stage for application. Such information could help agronomists develop strategies for high‐quality cereal production in stressful environments.

The use of plant growth-promoting rhizobacteria in crop production necessitates an understanding of the underlying mechanisms. We investigated the potential mechanisms of plant growth promotion by Streptomyces rochei S32 in wheat and tomato crops. MethodsThe effects of S. rochei S32 on plant growth and its antagonistic activity against soil-borne pathogenic fungi were tested in petri dishes. The underlying molecular mechanisms were identi ed based on wholegenome sequencing and bioinformatics analysis. The results of genomic analysis were veri ed by widely targeted metabolomics and mechanism studies of plant growth promotion. ResultsThe growth of crop seedlings treated with the cell-free fermentation broth of S. rochei S32 was markedly improved in 15 d. This effect was demonstrated by increased plant height (24.7%) and root length (17.4%) of wheat (400-fold dilution), as well as extended root length (40.9%) of tomato (200-fold dilution). S. rochei S32 showed antagonistic activity against multiple pathogenic fungi, especially Macropoma kawatsukai. The bacterial genome contains an 8,041,158-bp chromosome and two plasmids. A total of 7486 annotated genes were classi ed into 31 Gene Ontology functional categories. Genomic analysis revealed the potential for the production of indole-3-acetic acid, fungal cell wall hydrolases, antibiotics (e.g., candicidin, streptothricin, borrellin, alba avenone), and siderophores. Thirtynine phytohormones and 2205 secondary metabolites were detected, including indole-3-acetic acid, phytosphingosine, haloprogin, acivicin, and corynebactin. Normal bacterial growth occurred on a nitrogen-free medium. ConclusionS. rochei S32 can promote plant growth directly or indirectly through nitrogen xation and production of phytohormones, extracellular hydrolases, antibiotics, and siderophores.
