Abstract Upper Egypt experiences high temperatures during summer and low winter, which significantly impacts the sowing dates of maize in this region. The productivity crops water use efficiency can be greatly affected by stress (SDs). Therefore, it is crucial to determine optimal irrigation level SDs based on local conditions. To assess effects, two levels were employed: (1) control (full applied) (2) 70% water. Field experiments conducted at National Water Research Center's studies research complex station Toshka. aim was evaluate limited irrigation) across five (early: mid-February March, normal: mid-June, late: mid-August September) both 2019 2020, order identify ideal date (SD) level. normal SD resulted an increased growth season length between plant emergence maturity. Conversely, late reduced number days until maturity, resulting higher grain yields (WUE). Notably, September, coupled with level, yielded highest WUE, a 7014 kg ha −1 WUE 0. 9 m −3 . Based findings, recommended that regions similar conditions consider cultivating seeds adopting achieve N uptake, traits (plant height, ear length, weight, rows per ear, index weight), yield, WUE.

One such strategy the application of potassium humate (Kh) and cobalt (Co), which have been reported to enhance resistance plants. Therefore, present experiment was designed investigate whether Kh Co could positively affect proline, chlorophyll mineral elements contents, antioxidant defense systems in turn will impact water under different irrigation strategies. In 2021 2022, open-field experiments were conducted by using split-plot design. The main plots divided represent (ST), with additional control full requirements (ST1). Four STs implemented, ST1, followed 75%, 50%, 25% ST2, ST3, ST4 respectively, next irrigation, requirements, so on. subplots, peanut plants treated tap (Control), at 2 g l −1 3 , Co, + . yield negatively affected implementation ST4, despite increase proline contents. Furthermore, decrease relative content, enzymes, protein, nutrient elements. However, or showed better improvements most studied parameters.

Published: March 26, 2024

Abstract The knowledge of proper fertigation across various irrigation levels is necessary for maximizing peanut yield and use efficiency in arid areas, it also can effectively alleviate the risk nutrient deficiency induced by water stress. This study evaluated effectiveness cobalt combined with two zinc application methods on uptake, yield, varying levels. A split-split plot experiment was carried out 2021 2022. Three gross requirement (GWR) (100%, 80%, 60%) were designated main plots. Subplots featured plants treated either 0 or 7.5 mg L −1 cobalt. sub-sub plots assessed chelated effects at rates 2 g via foliar soil applications. In comparison to control (100% GWR), uptake decreased, sodium being exception, there an increase pH 60% GWR. results showed significant reductions approximately 60.3% 38.1%, respectively. At this level, applying soil, alone cobalt, led increases 89.7% 191.3% relative control. Also, it’s crucial note that negatively affected iron copper GWR, but impact lessened soil-applied zinc. Hence, under a similar circumstance, treating stressed additional applications + could enhance improve yield. On other hand, 80% combination foliar-applied had tremendous absorption (nitrogen, phosphorus, magnesium, zinc), resulting enhanced agronomic traits decreased losses. Additionally, yielded 32.4% compared GWR When 70.0% surge use. Based knowledge, suggests using strategy aids countering adverse stress, ultimately leading efficiency.
