“…The yield increase could be attributed to healthier seeds and improved crop development due to optimal soil moisture in drip-irrigated wheat. DI not only conserves water but also enhances yield, consistent with other studies (Dhawan, 2002;Tiwari et al, 2003;Yuan, 2003;Suna et al, 2023). These results mirror research indicating increased yield and water productivity with DI (Kharrou et al, 2011;Tasal and Pawar, 2015;Wakchaure et al, 2023).…”

This study addresses efficient water usage in wheat cultivation in a semi-arid region of India with clay loam soil and an increasing water supply-demand gap. It focuses on optimizing drip irrigation (DI) scheduling, of wheat crops, based on canopy air temperature difference (CATD) using the crop water stress index (CWSI). The field experiments were conducted for two winter seasons, employing high-discharge drip irrigation (DI) on wheat crop (variety - GW 366) at Junagadh Agricultural University (JAU), Gujarat, India. The experiment had nine treatments, each replicated three times in randomized blocks. The DI treatments labeled as T1 to T6, were irrigated at CATD values of -4, -3, -2, -1, 0, and 1 °C, respectively.. While T7 were irrigated by border irrigation. In order to define upper and lower baselines of CWSI, well watered treatments (T8) and extreme dry treatment (T9) DI were considered. The drip irrigation system (DIS) had an application rate of 7.78 mm/h with a uniformity coefficient of 90.40%. Compared to surface irrigation, DI resulted in water savings ranging from 3.52% (T1) to 43.24% (T6). Using real-time CATD data, the theoretical CWSI (CWSITh) and the vapor pressure deficit (VPD) based semi-empirical CWSI (CWSIVPD) were calculated as 0.3351 and 0.3668, respectively. CATD values showed significant variation in CWSI across treatments. The CWSI demonstrated sensitivity to water stress during critical growth stages. The study identified an optimal CATD of -1 °C, yielding 36.48% higher crop yield (4744 kg/ha), 30.23% water savings (388.42 mm), and notable 95.67% more water use efficiency (12.21 kg/ha-mm,), surpassing the outcomes of border irrigation (3476 kg/ha, 556.74 mm and 6.24 kg/ha-mm). These findings hold significant implications for farmers and policymakers, effectively addressing food and water security concerns. The study underscores the efficiency of DI combined with CATD-based irrigation scheduling in optimizing wheat crop performance. In the context of critical water management, this research provides essential insights for sustainable agricultural practices.

“…Drought stress is one of the most concerning abiotic stresses on crop production because it affects all living things that are present on the surface of the earth (Irfan, M., et al 2023), because of erratic rainfall and changes in the climate, drought stress on plants is becoming an increasingly common problem (Sarkhel, S., et al 2023), the rapid increase in atmospheric temperature has increased the crop's exposure to drought-related stress (Cotrina Cabello, G. G., et al 2023). The extent of the drought stress is unstable because it depends on a variety of variables, including the distribution and amount of rainfall, evapotranspiration, and the soil's capacity to retain moisture (Suna, T., et al 2023). Drought stress lowers crop productivity, which impacts plant water uptake, leaf water status, and gas exchange rates (KHOULOUD, Z., et al 2023).…”

Zinc is a crucial micronutrient found in food that is essential for the development of all living organisms, it plays a vital role in gene expression and various physical processes, its deficiency can lead to disease onset and reduce crop yield, restrict plant development, and lower the quality of produced goods, zinc is also used in fertilizers and the handling of metals to protect them from oxidation. Additionally, Zinc is important in enhancing the human immune system, and its deficiency can result in hair loss, memory loss, skin disorders, and muscular weakness.

“…Enhancing WUE ensures maximizing yield per unit of water, rather than yield per unit of land. Therefore, improving WUE will be reflected in sustainable use of limited water resources 6 , 7 . Deficit irrigation (DI) and the incorporation of soil amendments, including hydrogels, have been proposed to enhance WUE and mitigate negative impacts of water stress in arid and semi-arid regions 8 , 9 .…”

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