Effect of super absorbent hydrogel on hydro-physical properties of soil under deficit irrigation

Scientific Reports, Год журнала: 2024, Номер 14(1)

Опубликована: Апрель 1, 2024

Abstract Due to water scarcity challenges, efficient management of irrigation is becoming crucial. Water use efficiency (WUE) involves increasing crop productivity without consumption. This study was carried out the effect hydrogel, deficit and soil type on WUE, hydro-physical properties lettuce productivity. For this purpose, four treatments (100%, 85%, 70% 60% full requirements), hydrogel concentrations (0, 0.1, 0.2 0.3% w/w) three textural classes (clay, loamy sand, sandy-clay soil) were conducted in pot experiment at open field during two consecutive seasons. The results revealed that growth parameters significantly affected by application rates. Hydrogel addition enhanced head fresh dry weights, chlorophyll content, number leaves WUE. Application 85% requirements achieved highest WUE significant yield reductions. Changes studied more dependent texture rate than amount water. decrease saturated hydraulic conductivity bulk density confirms super absorbent hydrogels could be recommended improve retention enhance under conditions.

Potential of Soil Conditioners to Mitigate Deficit Irrigation Impacts on Agricultural Crops: A Review

Water Resources Management, Год журнала: 2024, Номер 38(8), С. 2961 - 2976

Опубликована: Фев. 28, 2024

Abstract In light of the current water scarcity, one strategy for reducing consumption in irrigated agriculture is to reduce amount irrigation compared full crop or other words deficit irrigation. Deficit management may be a critical issue due climate change. Incorporation different soil conditioners can improve hydro-physical properties and mitigate negative effects water-stressed conditions. Recent review articles either addressed specific behavior under covered single type conditioners. This manuscript represents an inclusive providing insight into methods incorporated with Crop response discussed some mathematical models. Three main types are covered: bentonite, biochar, super-absorbent polymers. Mechanisms associated each conditioner enhance retention highlighted as well. Previous study findings were comparatively future prospective, recommendations challenges addressed.

Root distribution, soil water depletion, and water productivity of sweet corn under deficit irrigation and biochar application

Agricultural Water Management, Год журнала: 2023, Номер 279, С. 108192 - 108192

Root modifications can play a vital role in crop adjustments to soil water deficit. It is important understand root growth and depletion patterns develop effective cropping systems, especially semi-arid regions like Texas High Plains (THP). This study evaluated growth, depletion, productivity (WP) of sweet corn under three deficit irrigation treatments [100 %, 70 % 40 evapotranspiration (ETc)] biochar application (hardwood softwood). The experimental units were replicated 4 times split-plot design. results revealed no interaction between for almost all measured parameters. ETc treatment increased the length density (RLD) over 100 during 2019, while differences observed among 2020. Both irrigations (70 ETc) compared ETc, highest being ETc. maintained similar yield WP by 21 across two years. However, resulted significant decline hardwood RLD without affecting status WP. Long-term studies are needed investigate effects beyond years application. In case limited availability, be recommended as an alternative THP US.

Optimizing irrigation and N fertigation regimes achieved high yield and water productivity and low N leaching in a maize field in the North China Plain

Agricultural Water Management, Год журнала: 2024, Номер 301, С. 108945 - 108945

Over-input of nitrogen (N) fertilizer coupled with flood irrigation resulted in low N and water productivity serious NO3--N leaching maize fields the North China Plain (NCP). Drip-fertigation can enhance water-N use efficiency by precisely regulating application. In this study, a three-year drip-fertigation experiment on was carried out during 2018–2020 growing seasons three levels, i.e. 50 (W1, 100 %), 40 (W2, 80 30 mm (W3, 60 five 0 (N0), 90 (N1), 180 (N2), 270 (N3), 360 (N4) kg ha−1 were designed to investigate responses soil consumption, distribution, grain yield (GY), uptake (UN), different application regimes. The results demonstrated that % deficit (W2) obtained comparable GY sufficient (W1), but significantly increased (WP) 7.2 compared W1. Soil contents 0–100 cm layers as rate increased, decreased increase level. When exceeded ha−1, 60–100 greatly increased. With increasing rate, first then tended be stabilized when reached UN showed an trend, while agronomic (AEN) recovery (REN) firstly decreased. consumption ranged from 374 388 186 257 respectively, WP 95 maximum values AEN got 70 value, simultaneously. conclusion, regime at about level (per event) is recommended for drip-fertigated NCP.

Potential Improvements in Crop Production in Egypt and Implications for Future Water and Land Demand

International Journal of Plant Production, Год журнала: 2024, Номер 18(3), С. 313 - 334

Abstract Similar to numerous water- and data-scarce regions, Egypt confronts a critical challenge in sustaining food production for its rapidly growing population. Consequently, the country’s water land resources are under considerable stress require careful management. About half of Egypt’s both annually harvested areas renewable freshwater allocated cultivating rice, maize, wheat, berseem clover. However, extent which crop might be improved how this would impact future requirements remains poorly understood. We analyzed potential improvements these crops quantified their different scenarios. Potential were detected through percentile analysis three remote sensing-derived performance indicators each Nile Delta’s Zankalon region: (i) yield, (ii) productivity, (iii) transpiration fraction (transpiration actual evapotranspiration, T/AET). applied improvementsto construct plausible scenarios sustain domestic until 2050. Our findings indicate limited improve T/AET (< 4%). up 27% yields 14% productivity possible. To meet targets by 2050, national must increase 128, 78, 69, 71% above 2016–2020’s average berseem, respectively. Depending on improvement levels developed scenarios, total area between 5.3 6.4 million ha will required with 18% 28% 36% berseem. Associated amount 59–68 billion cubic meters, divided into 23% 34% 15% Interventions increasing benefit more summer (rice maize) than winter (wheat berseem). discuss likely interventions meeting supply Egypt.
