“…Expanding the available area for paper. These findings align with the observations made by Abd El-Azeiz et al (2021) [11] and Salim et al (2022) [16] , who reported notable variations in leaf area. As for intercropping systems, we notice from same table that there are significant differences between arithmetic means of intercropping systems in leaf area trait, as the single soybean treatment recorded highest average for trait, amounting to (205.25) cm 2 , while (2: 2) loading system gave lowest average for trait, amounting to (176.20).…”

A field experiment was carried out in Hissar area of Kirkuk Governorate during the fall season of 2023 AD to determine effect of intercropping systems for Maize with three varieties of soybeans on growth and seed yield in soybeans. Experiment was carried out according to Randomized Complete Block Design (R.C.B.D) and with three replications, as study included two factors. First was three varieties of soybeans, namely (Lee, D, and Shaima), and the second was four intercropping systems, namely (Maize alone), (soybeans alone), (Maize line + soybean line), and (two maize lines + two soybean lines). The following results are that intercropping system (1 maize: 1 soybean) was superior in plant height, reaching (106.08) cm, while soybean cultivation alone was superior in traits of leaf area, number of vegetative branches, number of pods per plant, and in single plant yield, with means reaching (205.25) cm and (8.70) shoots. Plant and (99.71) pods. Plant and (33.22) grams. As for varieties that surpass Shaima variety in plant height, leaf area, number of branches on plant and weight of 300 seeds, it reached (128.14) cm, (191.47) cm 2 and (8.45) branches. Plant and (38.66 grams, respectively, and Lee variety was superior in number of pods per plant and Single plant yield, reaching (101.38) pods. Plant and (32.70) grams. plant. As for interaction between parameters of varieties and intercropping systems, intercropping system (1 maize: 1 soybean variety, Shaima) gave highest average for two traits of plant height and weight of 300 seeds, amounting to (142.23) cm and (39.66) grams, respectively and intercropping system surpassed planting alone for Shaima variety in number of branches. Vegetative growth reached (9.60) branches of a plan and intercropping system (2 maize: 2 soybean variety Lee) was superior in number of pods per plant at a rate of (105.63) pods. A plant, while the loading system was superior to cultivation alone for Lee variety in terms of single plant yield, reaching (33.56) gm.

“…One possible explanation can be attributed to the Si ability in modifying cell wall metabolism by improving cell wall enlargement and tissue extensibility, 25 or avoiding chlorophyll damage. 14 These improvements in plant growth due to different methods of Si application were previously reported in salt-stressed sunflower plants, 21,27 faba bean, 23 cucumber, 32 sunflower, 26,30 soybean plants, 45 and cotton. 46 The results suggest that Si has the ability to improve plant growth under different salinity conditions.…”

BACKGROUND Soybean is widely cultivated around the world, including regions with salinity conditions. Salt stress impairs plant physiology and growth, but recent evidence suggests that silicon (Si) is able to mitigate this stressful condition. Therefore, the purpose of this study was to evaluate how different strategies of Si application impact on salt stress tolerance of an intermediate Si accumulator species (soybean). Therefore, we applied four treatments: Si‐untreated plants (Si 0); foliar spraying at 20 mmol L−1 (Si F); nutritive solution addition at 2.0 mol L−1 (Si R), and combined foliar spraying at 20 mmol L−1 plus nutritive solution at 2.0 mmol L−1 (Si F + R). We investigated how Si application modified growth, leaf gas exchange, photosynthetic pigments, chlorophyll fluorescence, relative water content (RWC), nutrient accumulation, and ion homeostasis of soybean plants submitted to different levels of salt stress (50 and 100 mmol L−1 NaCl). RESULTS Salinity induced an expressive reduction in ion accumulation, plant water status, and growth of soybean, while Si application promoted contrary effects and increased potassium (K+) accumulation, water status, photosynthetic pigment content, chlorophyll fluorescence parameters, and gas exchange attributes. Additionally, Si application enhanced Si accumulation associated with decreased Na+ uptake and improved morpho‐physiological growth. CONCLUSION The use of exogenous Si can be an efficient strategy to attenuate the harmful effects of salt stress in soybean plants. The best application strategy was observed with combined foliar spraying with Si included in the nutritive solution (Si F + R). © 2023 Society of Chemical Industry.

“…Additionally, the increased seed yield under hot conditions indicates the potential of Giza 111 as a resilient crop variety for regions with high temperatures and salinity levels. The best way to increase vegetative growth, chlorophyll content, leaf relative water content, proline content and antioxidant enzyme activity was to spray arginine at a dose of 300 mg/L with Giza 111 60 . These data indicate that each of these two factors act dependently on seed yield and yield components.…”

Background and Objective: Agriculture in Upper Egypt faces challenges due to the region's high salinity and high temperatures. A field trial was conducted in 2021 and 2022 summer seasons at the newly reclaimed soils of the Agricultural Research Station of Al-Marashda, Qena Governorate, Egypt. The study aimed to evaluate the effects of foliar spraying of amino acids with micronutrients in addition to water (as control), on seed yield and its quality of Giza 21, Crawford and Giza 111 under reclaimed soil conditions in Upper Egypt. Materials and Methods: Twelve treatments were the combinations between foliar spraying of four rates of amino acids with micronutrients (1.0, 1.5 and 2.0 cm 3 /L in addition to water as control) and three soybean varieties (Giza 111, Giza 21 and Crawford). The experiment was arranged in a split-plot design with three replicates, foliar spraying of amino acids with micronutrient rates was assigned in the main plots and the three soybean varieties were distributed in the sub-plots. Results: The Giza 111 variety showed superior performance compared to other varieties, exhibiting the highest vegetative growth when treated with 2.0 cm 3 /L of amino acids and micronutrients on its leaves. At harvest, foliar spraying of amino acids with micronutrients at a rate of 2.0 cm 3 /L on soybean plants led to superior seed yield and its components, as well as seed quality, compared to the other rates. Similarly, Giza 111 outperformed Crawford in terms of pod number/plant, seed yield/plant and seed yield/fad, as well as seed quality. Conclusion: The Giza 111 exhibited a significant increase in seed yield and its quality when treated with 2.0 cm 3 /L of amino acids with micronutrients, leading to the highest profitability under environmental conditions in Upper Egypt.
