The availability and quality of irrigation water in Egypt have become major challenges for the agricultural sector. Thus, increasing productivity improving efficiency are critical goals. A field experiment was conducted under Upper conditions at El-Mattana Agricultural Research Station, Luxor governorate, Egypt, to evaluate effects different methods traditional furrow (Ti), surge (Si), alternate (Ai), on productivity, growth, yield wheat clay loam soil. cultivar MISR2 (Triticum aestivum L.) cultivated during 20/21 21/22 growing seasons, using scheduled after 50% depletion soil available water. results indicated that treatment Si produced greatest plant height (115.0 117.7 cm) grain (7.99 8.16 t ha⁻¹) both respectively. In contrast, Ai resulted lowest values these traits (106.4 107.2 cm 6.94 6.24 ha⁻¹ yield, respectively). total annual rainfall two seasons were recorded as 0 mm. highest amount applied (6522, 6427.2 m3 ha-1) with Ti; while (5493.6, 5175.1 treatments 20/21, (1.75 kg m-3 1.35 first season 1.44 1.20 second Si, most effective saving water, by 15.8% 19.48% over seasons. These suggesting an extra may be saved without any significant loss when applying method. This research contributes developing evidence-based management strategies production arid regions.

Synergistic effect of ammonium and potassium on carrot growth, physio-biochemical mechanisms, and water use efficiency under varying irrigation regimes

Scientific Reports, Journal Year: 2025, Volume and Issue: 15(1)

The beneficial effects of ammonium nitrate and potassium humate on carrots are well-documented. However, their impact physiological biochemical mechanisms under varying irrigation conditions still needs to be explored. Here, we investigated the soil-applied foliar-applied physio-chemical characteristics water use efficiency carrot plants three levels: 100%, 80%, 60% crop evapotranspiration (ETc). Carrot were treated with two rates soil (200 250 kg N ha- 1), foliar 400 g 100 L- four combinations these treatments. Under 80% ETc, combined applications significantly influenced leaf contents chlorophyll a, nitrate, ammonium, catalase, carbohydrate, soluble sugar patterns, enhancing osmotic regulation deficit conditions. Interestingly, when irrigated by 100% ETc instead 80 sprayed 1 in combination was decreased 49.2 30.7%, respectively. We attributed that to: a), observed increments NH4 concentrations leaves which caused negative impacts chlorophyll, b) change C/N N/P ratios. This highlights importance choosing a suitable pattern for crops is adapted. Overall, using at rate 200 attained highest yield efficiency.

Improving maize yield in newly reclaimed soils: effects of irrigation, mulching, and foliar treatments

BMC Plant Biology, Journal Year: 2025, Volume and Issue: 25(1)

Published: May 14, 2025

Abstract Improving maize yield in newly reclaimed soils presents major challenges. This study analyzed the impact of various irrigation methods (drip, sprinkler, and surface), foliar applications (potassium bicarbonate (PoB), methanol, water control), mulching techniques (with without rice paddy straw) on growth, physiology, productivity, use efficiency (WUE) soil over two seasons 2022 2023. The employed a split-split plot design arranged randomized complete blocks with three replications. integration drip irrigation, PoB spray, straw yielded superior results, improving grain (GY,10.0-13.08 t/ha) biological (BY, 51.37–59.53 comparison to control treatments. findings were validated through multivariate analyses, such as principal component analysis (PCA), structural equation modeling (SEM), hierarchical clustering heatmap, radar visualization. PCA revealed that initial components accounted for 85.6% total variance, growth parameters exhibiting strong correlation first (76.8%). Also, SEM BY (0.603), plant height (0.594), net assimilation rate (0.589) exerted most significant direct positive influences GY. Drip demonstrated highest WUE at 3.70 kg/m³, significantly surpassing sprinkler 3.32 kg/m³ surface 3.03 kg/m³. Mulched plots showed better (3.53 kg/m³) compared non-mulched (3.17 kg/m³), application yielding (3.80 kg/m³). Seasonal variations noted, combined mulch reaching (4.20 season, whereas performance (5.49 second season. results highlight opportunity enhance yields soils, potassium application, emerging innovative practice boosting crop optimizing use.
