“…Thus, the synergistic application of biochar and potassium humate gave a higher improvement in SOD, CAT, and POX than sole applications. Similar findings were reported previously [17,19].…”

“…Nutritional contents of onion were enhanced in potassium humate applied as the presence of biochar could have resulted in improved phenolic compound synthesis [28] which has to been linked to a positive relation between bulb carbohydrate, bulb soluble sugars, bulb protein, bulb flavonoid contents and potassium humate applied on onion. Bulb carbohydrate, bulb soluble sugars, bulb protein, and bulb flavonoid contents rely upon transported ions and organic solutes that are converted into glucose inside onion [17,25] where biochar and potassium humate application enhances glucose biosynthesis, contributing to improved quality traits in onion plants.…”

“…Regulation of stomatal conductance is a consequence of potassium inflow and outflow in the stomatal guard cells. Moreover, potassium humate improves the rate of nutrient uptake, plant growth, and productivity as a result of a hormone-like effect, activation of photosynthesis, accelerating cell division, increasing the permeability of plant cell membranes, and improving the plant response to salinity and water stress [17]. Potassium humate can be used as a cheap source of potassium [18].…”

Water scarcity, due to physical shortage or inadequate access, is a major global challenge that severely affects agricultural productivity and sustainability. Deficit irrigation is a promising strategy to overcome water scarcity, particularly in arid and semiarid regions with limited freshwater resources. However, precise application of deficit irrigation requires a better understanding of the plant response to water/drought stress. In the current study, we investigated the potential impacts of biochar-based soil amendment and foliar potassium-humate application (separately or their combination) on the growth, productivity, and nutritional value of onion (Allium cepa L.) under deficient irrigation conditions in two separate field trials during the 2018/2019 and 2019/2020 seasons. Our findings showed that deficit irrigation negatively affected onion resilience to drought stress. However, these harmful effects were diminished after soil amendment using biochar, K-humate foliar application, or their combination. Briefly, integrated biochar and K-humate application increased onion growth, boosted the content of the photosynthetic pigments, enhanced the water relations, and increased the yield traits of deficient irrigation onion plants. Moreover, it improved the biochemical response, enhanced the activities of antioxidant enzymes, and enriched the nutrient value of deficiently irrigated onion plants. Collectively, these findings highlight the potential utilization of biochar and K-humate as sustainable eco-friendly strategies to improve onion resilience to deficit irrigation.

“…Also, K increases the permeability of water in plant membranes, leading to an increase in RWC in leaves. These match with (Kumar and Singh 2017;Ismail and Halmy 2018). Also, applying KH leads to increasing the absorption of Zn, Fe, and Mn than GWR70 control, which, in turn, promoted the enzymes of photosynthesis, and proteins led to improving the effectiveness of photosynthesis and increasing protein content.…”

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.

“…in both seasons application proline at rate 50ppm give the highest value. This may due to the role of proline in plant development particularly in reproductive phase (Awadalla, et al2020), (Ismail and Helmy, 2018) and (Marco et al2015). Concerning the interaction between sowing dates and plant methods, (A×B) had a significant effect on Number of seeds/capsule.…”

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.
