ABSTRACT Background Drought stress (DS) impedes plant growth and development by impairing the uptake of nutrients, such as magnesium, which is central to many physiological processes, particularly photosynthesis. Leaf application was proposed be an effective strategy compensate for inadequate Mg 2+ supply from nutrient solution. Aim The present study designed investigate role leaf in ameliorating anatomy chloroplast ultrastructure changes faba beans grown under DS. Methods Hydroponically plants were subjected DS various levels , i.e. sufficient (0.5 mM), deficient (0 leaf‐application (250 mM). Light transmission electron microscopy (TEM) conducted examine ultrastructural changes. Results deficiency alone significantly affected biomass Additionally, sucrose concentration, oxidative stress, lipid peroxidation increased. Accordingly, excessive deposition photoassimilates source organs due inhibition phloem loading results a disruption thylakoid structures leading damage. In current partially ameliorated functions, most notably chlorophyll photosynthesis transpiration rate, biomass, preservation chloroplast. Conclusion Although via roots enhanced drought tolerance, compared application. However, proven efficient mitigating field trials. Therefore, foliar should prioritized further investigation relevant environmental conditions.

Using conservation tillage to grow crops that enhance soil quality, such as legumes, seems be one of the best solutions for sustainable agriculture. The field study was conducted identify effect cultivation technology and fertilization, via strip-tilling (reduced) vs. plowing (conventional), on availability uptake NPK Mg, well growth shoots roots yield green peas (Pisum sativum L.). research carried out in central Poland (53°05′16.8″ N, 19°06′14.4″ E) over two growing seasons 2016 2017. Our has shown spatial distribution macroelements is influenced by method. nutrient peas, their parameters, were also system. However, observed mainly first year study, which had less precipitation higher temperatures. In general, our strip-till a positive impact plants, contributing longer biomass accumulation, especially part season. 2016, with rainfall, under produced more pods per plant than (by 13.8%). 2017, precipitation, an increase compared 9.1%), but this difference not statistically significant. To sum up, strip-tillage have macroelements, can recommended production crop.

Nutrient deficiencies are a major cause of yield loss under abiotic stress conditions, so proper nutrient management can reduce the negative effects to some extent. Nutrients alleviate by activating resistance genes, enhancing antioxidant enzyme activity, creating osmoprotectants in cells, reducing reactive oxygen species (ROS) increasing cell membrane stability, synthesizing proteins associated with tolerance, and chlorophyll content leaves. The current review highlights changes soybean metabolic activity caused drought vital functions deficiency primary (N, K, P) secondary macronutrients (Ca, Mg, S). role adverse water deficit is highlighted. Under stressed appropriate options be implemented minimize ensure good yields. Balanced fertilization helps activate various plant mechanisms mitigate stresses improve resistance/tolerance. therefore viable technique for environmental crop productivity.
