“…Micronutrients have a unique role in plant growth and development and, in many cases, represent a limiting factor for maximum production. − Various application methods of micronutrients in plants through broadcast, foliar spray, and pre-sowing seed treatment methods are being followed. − Furthermore, applying micronutrients through the soil and seed treatment could assist plants through early critical growth stages toward yield improvement. , However, among those micronutrients, iron is special in many aspects due to its sensitivity to many climatic and edaphic conditions that facilitate its fixation or unavailability. , Iron is one of the essential elements for plant growth and is crucial in photosynthetic reactions, activating numerous enzymes involved in the transfer of energy, reduction and fixation of nitrogen, the formation of lignin, and its contribution to ribonucleic acid synthesis . Zinc is the second most abundant transition metal in organisms after iron.…”

Nanocitrates of iron (Fe) and zinc (Zn) in the form of plant nanonutrients were examined for their behavior in soil and the uptake of these by 20-day old groundnut (Arachis hypogaea) seedlings under greenhouse conditions. The Fe (0.04 to 0.008 mmol/kg of soil) and Zn (0.02 to 0.004 mmol/kg of soil) nanocitrates were applied to soil and compared with commercial counterparts (FeSO 4 , ZnSO 4 , nano-Fe, nano-Zn, Fe-EDTA, Zn-EDTA). The combined nanocitrate compositions were also formulated by physical means and characterized. The plant uptake of Fe and Zn was determined through atomic absorption spectrometry (AAS). All the treated plants showed good germination and higher vigor indexes compared to the control treatments. The highest available Fe and Zn soil contents after leaching were 150.5 and 18.9 mg/kg, respectively, in combined nanocitrate compositions, whereas in the control (untreated) soil, the Fe and Zn contents were 6.0 and 0.7 mg/kg, respectively. The plant's Fe content was 0.48 mg/pot for the combined nanocitrate composition, and that of the untreated plant sample was 0.02 mg/pot. The plant's Zn content was 82.3 μg/pot for pure zinc citrate, and the respective untreated-plant Zn content was 2.1 μg/pot. These values are better than those observed for commercial fertilizers. Additionally, no trend in promotional and antagonistic correlations between Fe and Zn in combined nanocitrates was observed in the studied period (20 days in duration). Among the 34 synthesized citrates, six nanocitrates show promising trends for evaluation under field conditions with higher stability.

“…The sample containing 10 vol % CF (WG100CF10) degraded slightly faster than the WG100, possibly due to voids between the CF and WG matrix facilitating the microorganism’s interaction with the protein matrix (Figure a). The sample’s biodegradation behavior aligns with previous reports on thermally processed protein-based bioplastics . Thus, it was demonstrated here that gluten could be used as a matrix to produce single-use thermoprocessed microplastic-free items with rapid biodegradability.…”

Biocomposites based on wheat gluten and reinforced with carbon fibers were produced in line with the strive to replace fossil-based plastics with microplastic-free alternatives with competing mechanical properties. The materials were first extruded/compounded and then successfully injection molded, making the setup adequate for the current industrial processing of composite plastics. Furthermore, the materials were manufactured at very low extrusion and injection temperatures (70 and 140 °C, respectively), saving energy compared to the compounding of commodity plastics. The sole addition of 10 vol % fibers increased yield strength and stiffness by a factor of 2−4 with good adhesion to the protein. The biocomposites were also shown to be biodegradable, lixiviating into innocuous molecules for nature, which is the next step in the development of sustainable bioplastics. The results show that an industrial protein coproduct reinforced with strong fibers can be processed using common plastic processing techniques. The enhanced mechanical performance of the reinforced protein-based matrix herein also contributes to research addressing the production of safe materials with properties matching those of traditional fossil-based plastics.

“…Horticulture is a branch of agriculture that includes study of the growth and productivity of vegetables, fruits, and ornamental or medicinal crops (Jiménez-Rosado et al 2022). Global horticulture production in 2020 was 329.86 million tons, which represents an increase of nearly 2.93% compared with 2019 (FAOStat 2022).…”

GRICULTURE is very important for humanity as it supplies human needs ranging from food to fiber, feed for animals and energy. The production of seedlings is of great agricultural importance, especially in horticultural nurseries. Producing vigorous and healthy seedlings like banana and strawberry using biological nanofertilizers (bionanofertilizers) is presented in this mini-review. Due to their properties, bionanofertilizers have received increasing interest in agriculture, particularly during transplanting or the production of seedlings. Many studied seedlings attributes, such as the plants' antioxidants systems, nutritional status, and quality parameters of seedlings have been improved through the use of bionanofertilizers. The most important impacts of bionanofertilizers may include enhancing production of seedlings or plants under biotic and abiotic stresses through the improvement of attributes like physiological, biochemical, and molecular characteristics. This diagrammatic mini-review will focus on biological nanofertilizers and their potential uses in horticultural crop production.
