“…So, under drought conditions, cell division and increase in cell size are difficult to achieve, which further prevents stem elongation and reduces plant height. Gholinezhad (2017) observed that nano-Fe 3 O 4 fertilizer increased plant height and biomass dry yield by about 20% compared to the control (no fertilizer) condition.…”

Drought is one of the most destructive abiotic stresses that impact the growth, physiology, yield, and nutritional quality of seeds of crop plants. In modern agriculture, the use of nanoparticles can be beneficial due to their large surface area and higher potentiality to enter into the plant leaf during foliar application. This study aims to evaluate the effects of foliar spray containing varying doses (0, 100, and 200 ppm) of the nano-iron (Fe3O4) on the growth, physiology, yield, and seed nutritional quality of soybean under drought (40% of field capacity, FC) and well-watered (80% of FC) conditions. Leaf water status, chlorophyll content of leaves, the height of the plant, fresh leaf weight, fresh stem weight, fresh petiole weight, total dry weight, seed yield, and protein and oil content in soybean seeds were found to be suppressed by the applied drought stress. Under both drought (40% of FC) and controlled well-watered (80% of FC) conditions, the foliar application of nano-iron substantially improved the growth, physiology, yield, and quality of soybean seeds. The nanoparticles at 200 ppm increased soybean seed yield by 40.12 and 32.60% in drought and well-watered conditions, respectively, compared to the untreated plants. Furthermore, nano-iron increased the oil content of soybean seeds by 10.14 and 7.87% under drought and well-watered conditions, respectively, compared to the untreated control. Our results indicate that the application of nano-iron improved drought tolerance, yield, and seed quality of soybean, so exogenous foliar sprays of 200 ppm Fe3O4 were more effective than the other treatments in enhancing drought tolerance and can be utilized to reduce losses caused by drought stress in soybean-growing areas.

Other NPs that have enhanced photosynthesis under DS include iron nano‐fertilizer (Gholinezhad, 2017), nano‐chelated nitrogen (Astaneh et al, 2021), Paulownia‐based nano‐fertilizer (Sohrabi et al, 2022), and potassium nano‐fertilizer (Rostami Ajirloo & Amiri, 2022).…”

Balanced photosynthesis is essential for improved plant survival and agricultural benefits in terms of biomass and yield. Photosynthesis is the hub of energy metabolism in plants; however, drought stress (DS) strongly perturbs photosynthetic efficiency due to biochemical and diffusive limitations that reduce key photosynthetic components and close stomata. This review describes photosynthetic responses, chloroplast retrograde signalling, and genetic imprints that curtail DS damage to photosynthetic machinery. While stomatal closure, disrupted photosynthetic systems, over‐reduced electron transport rates (ETR), partial hindrance of the Calvin cycle, and reduced pigment contents strongly affect the repertoire of photosynthetic processes under DS, chloroplast retrograde signalling also has a plausible role in preserving photosynthetic capacity. Progress in agronomic, genetic engineering approaches and isoprene regulation would help to rescue photosynthetic apparatus under DS.

“…They have broad application prospects in biological fields such as bioimaging, biosensing, photocatalysis, and gene delivery. − Since the discovery of fluorescent CDs during the purification of single-walled carbon nanotubes in 2004, different methods for preparing CDs including laser ablation, electrochemical, hydrothermal/solvothermal, and microwave-assisted methods have been developed. Using a carbonization method to prepare CDs also has been reported. − In the past few decades, abundant CD materials have been developed for agriculture applications, for example, monitoring crop health, promoting crop growth, improving the efficiency of fertilizers and pesticides, , controlling diseases and pests, environmental stress, and many other fields. − Compared with other metal-based nanomaterials, carbon-based nanomaterials have lower environmental toxicity and higher biocompatibility due to their nontoxic carbon backbone. − However, in the current research, the synthesis of CDs is small scale, and methods for the mass production of CDs have rarely been reported.…”

In this research, we developed a simple, low-cost, and environmentally friendly method to prepare biomass carbon dots (CDs). We have obtained CDs with high yield, good water solubility, low toxicity, and excellent fluorescence performance by carbonizing peanut bran at high temperature. These CDs can be further used in agricultural production. We found that the peanut bran CDs had a dose−effect relationship on Italian lettuce growth. The fresh weight of the Italian lettuce cultivated under the appropriate concentration of CD solution was 24.3% higher than that of the control group. The contents of K, P, and N in the nutrient solution were decreased, demonstrating the significant improvement of the utilization rate of chemical fertilizers after CD treatment. Our work shows the considerable application prospects of as-prepared CDs in agricultural production.
