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.

Accurate regional crop classification, acreage estimation, yield prediction, and water requirement assessment are essential for effective agricultural planning market forecasts. This study uses an integrated geospatial statistical approach to assess major winter crops wheat sugarcane cultivation in Ghotki District, Pakistan, from 2017/18 2022/23. It combines satellite data Landsat 8 Sentinel-2, ground truthing, reporting records analyze key factors such as area, gradients, vegetation health, normalized difference index (NDVI)-based models, requirements, total irrigation consumption. Results showed that areas ranged 15% 19%, with the highest coverage observed 2021/22 season. Sugarcane 6% 10%, peaking 2018/19 A strong linear association between NDVI (R2 = 0.86) was observed. Wheat predictions utilized regression, robust regression all of which were validated by findings. Irrigation demand season calculated at 1887 million cubic meters (MCM) 2017/18, 1357 MCM supplied Sindh Drainage Authority (SIDA). By 2020/21, reached 2023 MCM, while SIDA’s supply MCM. These results highlight significance integrating analysis provide timely, reliable estimates cropped areas, forecasting, dynamics, planning. The proposed methodology contributes a scaleable solution informed decision-making resource management, applicable across other districts Pakistan on global scale.

Climate changes and the cost of irrigation water in semi-arid areas seriously reduce availability for irrigation. The optimal allocation resources to limit overexploitation are necessary these regions. A field trial aimed evaluate regimes (60, 80, 100% based on capacity, abbreviated as FC60, FC80 FC100) organic fertilizer (0, 15, 30 t ha-1 farmyard manure, FYM) two rapeseed varieties (Hydromel Nathalie) region Qazvin, Iran. highest lateral growth (branch number) was observed Hydromel cultivar with application 15 manure (FYM30 FYM15) under FC100 conditions. Comparison between cultivars showed that Nathalie less affected by FYM chlorophyll content decreased FC60; however, no significant difference FC100. maturity earlier than Hydromel.

In arid and semiarid regions, agricultural producers, including cashew growers, grapple with the challenges of cultivating crops in harsh environmental conditions. To address this issue, conditioning materials capable maintaining soil moisture levels even during droughts presents a promising solution. Herein, we synthesized superabsorbent hydrogel composite comprised starch-grafted-poly(sodium acrylate) embedded 20% (w/w) kaolin (KAO), designed to enhance quality seedlings. Characterization through Fourier transform infrared (FTIR) X-ray diffraction (XRD) analyses confirmed its successful synthesis. The incorporation KAO influenced thermal, morphological, swelling properties composite, as result interaction between clay starch. Moreover, exhibited improved water absorption capacity kinetics, demonstrating behavior. Our findings demonstrated that addition just 1% effectively enhanced retention. Notably, placement within column proved critical extending interval irrigation cycles. Field experiments revealed seedlings cultivated conditioned positioned deeper pot notable improvements morphological parameters such plant height, stem diameter, leaf count, especially over prolonged cultivation periods. Besides, these displayed increased vigor overall quality, essential for establishment robust healthy orchards. Overall, study underscores potential cost-effective material enhancing cashews other crop yields regions limited availability.
