Background: The use of lanthanum (La) as a rare element has increased in agriculture. Summer savory (Satureja hortensis L.) is an herbaceous and medicinal plant that has received attention recently. The present study aimed to investigate the effects of foliar application of zinc (Zn), copper (Cu), manganese (Mn), and La at different growth stages, including vegetative, reproductive, and vegetative to harvest on morphological and physiological traits of S. hortensis under hydroponic and soil conditions in the greenhouse. The study was arranged in a factorial experiment based on a completely randomized design (CRD) with three replications.
Results: Results of hydroponic condition showed that foliar application of Cu, Zn, and Mn were the most effective treatments to improve the measured morphological and physiological traits. Moreover, La was not more appropriate in increasing the quantitative and qualitative characteristics. Also, results showed that in soil cultivation, foliar application of micronutrient elements increased the ratio of leaf-to-stems, antioxidant compounds, and the percentage of essential oils, while the application of Mn, Cu, Zn, and La did not have positive effects on the increase in vegetative characteristics in all three stages of foliar application compared with the control treatment.
Conclusions: Cu, Zn, and Mn in appropriate concentrations can increase growth and physiological characteristics of summer savory in hydroponic systems.

Nanoparticles play a significant role in enhancing crop yield and reducing nutrient loss through precise nutrient delivery mechanisms. However, it is imperative to ascertain the specific plant physiology altered by these nanoparticles. This study investigates the effects of green-synthesized nanoparticles, specifically boron nitride and sulphur, on sunflower yield, seed quality, and physiological activities.

Background: The imbalance between Egypt's water requirements and supply necessitates the use of unconventional water sources, such as treated sewage water (TSW) and agricultural drainage water (ADW), to combat water scarcity. This study investigated the effects of foliar glycine betaine (GB) on vegetative growth parameters, physiological characteristics, photosynthetic pigments, leaf element contents, anatomical leaf structures, and antioxidant activity. The experiment was conducted in two successive seasons (2021/2022 and 2022/2023) using Kapok seedlings irrigated with ADW and TSW at different mixing ratios with normal irrigation water (NIW) (25%, 50%, 75%, and 100%), combined with foliar spraying of GB at concentrations of 0.

Detrimental effects of terminal heat stress could be mitigated by exogenous application of synthetic compounds by preserving cell membrane integrity and protecting against oxidative damage. A field experiment was conducted to test the application of seven synthetic compounds on wheat growth traits: (1) thiourea (20 mM and 40mM); (2) potassium nitrate (1% and 2%); (3) sodium nitroprusside (400 μg mL-1 and 800μg mL-1 ); (4) dithiothreitol (25 ppm and 50ppm); (5) salicylic acid (100 ppm and 200ppm); (6) thioglycolic acid (200 ppm and 500ppm); and (7) putrescine (4 mM and 6mM). These compounds were applied at the anthesis and grain-filling stages to enhance physio-biochemical traits and yield attributes of wheat (Triticum aestivum ) cvs GW-11 and GW-496 under terminal heat stress.

Salinity is one of the predominant abiotic stressors that reduce plant growth, yield, and productivity. Ameliorating salt tolerance through nanotechnology is an efficient and reliable methodology for enhancing agricultural crops yield and quality. Nanoparticles enhance plant tolerance to salinity stress by facilitating reactive oxygen species detoxification and by reducing the ionic and osmotic stress effects on plants.
