“…Therefore, as a result of the many benefits mentioned earlier of applying KH, plants work on reducing the level of proline, which is considered a guide for improving plant conditions. In this regard, this study is not consistent with other studies claiming that applying K to stress plants leads to an increase in proline levels, as mentioned by (Bahrami and Hajiboland 2017;Desoky et al 2017;Jan et al 2019). In this concern, previous studies demonstrated that the relationship between proline and K varies and depends on such factors as (the taken plants part, the application methodology, and the used concentrations of K).…”

Previous studies have demonstrated the impact of potassium humate (KH) and chitosan (CH) on ameliorating drought effects, but their combined applications in promoting these benefits are still unfound. Therefore, the current study aims to evaluate the efficacy of KH and CH on corn growth, yield, nutrient contents, and water productivity under full and limited irrigation conditions. Under the drip irrigation system, a split-plot experiment was performed with three replications in the second week of February in the seasons of 2021 and 2022. The main plot was equipped with a valve and a flow emitter to control the amount of the targeted irrigation levels (full irrigation and limited irrigation from the development stage onwards), as well as four foliar applications in the subplot (0, CH 500 mg l−1, KH 3000 mg l−1, and CH 500 mg l−1 + KH 3000 mg l−1). It was found that separate foliar applications of KH or combined foliar applications of KH + CH had a significant impact on the most examined traits. However, compared to the control, adopting limited irrigation and applying combined applications thereof have significantly increased iron, zinc, manganese, oil, protein, yield, and water productivity. In addition, this combination decreased proline, and the maximum reduction was observed for the combined application with adopting full irrigation. In arid regions, the researcher recommends treating stressed plants with combined foliar applications of KH + CH, which could help plants overcome the negative effects of drought and attain the highest yield and water productivity.

“…This may due to the role of proline in plant development particulary in reproductive phase also, play vital role in response of plant to environmental stress and protein synthesis. Similar results were obtained by (Desoky et al, 2017), (Arif Shafi et al,2017) and (Khaled et al, 2020) sowing dates and plant methods (A×B) had a significant effect on oil % and oil yield (kg/fed. in both seasons.…”

Two experiments were conducted at South Valley Farm Research Station, Toshka Region, Agriculture Research Center during 2018 and 2019 seasons. To study the effect of different proline concentrations and planting methods and their interaction on the productivity of sesame grown under a drip irrigation system. The experiment was carried out in (RCBD) using strip-plot arrangement with three replications, The two planting methods (terraces and rows) were assigned horizontally while, the four proline concentrations (0.0, 25, 50 and 75 ppm) were allocated vertically. The result showed that the studied planting methods had a significant impact on plant height, frouting zone length, number frouting nods plant -1 , number of seeds capsule -1 , weight of seeds plant -1 , seed yield, oil %, and oil yield traits in both seasons in favor of rows planting methods in most traits except oil percentage in favor of terraces planting methods and proline 50 ppm sprayed at 45 and 60 days after planting DAP recorded significantly higher seed yield (579.02 and 586.99 kg fed -1 ) and yield attributes in both seasons, except plant height was not significant in the two seasons, frouting zone and oil percentage in the second season. The interaction between planting methods and proline concentrations had a significant impact on all traits in both seasons, except plant height and number of seeds capsule -1 in the 2 nd season and frouting zone in both seasons. Consequently, the maximum average values of oil yield (294.62 and 302.98 kg fed -1 ) in the 1 st and 2 nd seasons, respectively.

“…Proline accumulates when the amount of free amino acids in plant tissues increases with salt because higher salinity slows down protein synthesis (El-Leboudi et al, 1997). Farhad et al (2015), exogenous application of proline significantly boosted wheat growth, yield components including grain and straw yields, and these effects were positively correlated with higher percentages and absorption of N, P, K, and S. According to Desoky et al (2017), wheat's growth and production were improved by applying proline to the leaves at a rate of 0.2%, reducing the harmful impacts of drought stress.…”

In order to investigate the impact of foliar fertilization treatments (NPK fertilizer, nano-fertilizer, salicylic acid (SA) and proline acid and its mixture) on productivity and grain quality of wheat cultivar (Sids-14), two field experiments were conducted at a private farm in Ezab El-Arab Village, Aga District, Dakahlia Governorate, Egypt, during the 2020-2021 and 2021-2022 seasons. Under three irrigation treatments, the plants were given four irrigations (control), three irrigations were given while the second irrigation was skipped, and three irrigations were given while the final irrigation was withheld. The trials utilized a strip-plot design with three replications. The yield, its components, and the grain quality characteristics of wheat were drastically reduced throughout the course of the two growing seasons by missing the second irrigation or withholding the final irrigation. When spraying with a combination of NPK fertilizer + nano-fertilizer + SA + proline acid in both seasons, the greatest values of yield, its components, and grains quality characteristics of wheat were noted. Withholding the last irrigation (plants received 3 irrigations) and spraying a mixture of NPK fertilizer at the rate of 5 g/liter + nano-fertilizer at the rate of 0.75 ml/liter water + 200 ppm of salicylic acid at the rate of + proline acid at the rate of 200 ppm in each spraying under the environmental conditions of Dakahlia Governorate could be recommended in order to keep grain quality and high production, while simultaneously reducing water requirements.
