“…Yield and yield attributes of barley are influenced by levels of salinity are presented in Fig. 4, which revealing that productivity and water use efficiency reduced when salinity rates exceeded 6 dS m -1 (Abd El-Wahed et al, 2015). A better understanding of agronomical responses under conditions of salinity may help programs aiming to improve the salt tolerance of barley.…”

“…are grown in the Mediterranean region due to high tolerance against heat, drought, and salinity compared to other small grains (Zhou, 2009). Barley is considered an important cereal crop in several developing countries, including India, Nepal, Sri Lanka, and Bangladesh, where it is often subjected to severe drought stress that considerably influences crop productivity (Ceccarelli et al, 2007;El-Wahed et al, 2015). Drought experienced in the Mediterranean region is the result of low precipitation coupled with high temperatures in (Hossain et al, 2012a).…”

Drought and salinity stresses in barley: Consequences and mitigation strategies

Recent trends show reductions in crop productivity worldwide due to severe climatic change. Different abiotic stresses significantly affect the growth and development of plants, leading to decreased crop yields. Salinity and drought stresses are the most common abiotic stresses, especially in arid and semi-arid regions, and are major constraints for barley production. The present review attempts to provide comprehensive information related to barley plant responses and adaptations to drought and salinity stresses, including physiological and agronomic, in order to alleviate the adverse effect of stresses in barley. These stresses reduce assimilation rates, as they decrease stomatal conductance, disrupt photosynthetic pigments, reduce gas exchange, enhance production of reactive oxygen species, and lead to decreased plant growth and productivity. This review focuses on the strategies plants use to respond and adapt to drought and salinity stress. Plants utilize a range of physiological and biochemical mechanisms such as adaptation strategies, through which the adverse effects can be mitigated. These include soil management practices, crop establishment, as well as foliar application of anti-oxidants and growth regulators that maintain an appropriate level of water in the leaves to facilitate adjustment of osmotic and stomatal performance. The present review highlighted the adverse effect of drought and salinity stresses barley and their mitigation strategies for sustainable barley production under changing climate. They review also underscored that exogenous application of different antioxidants could play a significant role in the alleviation of salinity and drought stress in plant systems.

“…The differences between the Christiansen's uniformity coefficient (CUC, %) obtained with irrigation depths observed in the field tests and the CUC determined using irrigation depths estimated by one of the proposed methods were also compared. Simulations of CUC values were performed considering four sprinkler heads spaced 18 m x 18 m, by applying the equation 8 (El-Wahed et al, 2015;Maroufpoor et al, 2019):…”

“…The more uniform the water application, the higher the DE Pa , the lower the loss through deep percolation and the smaller the water deficit in the fraction of the irrigated land area that received an irrigation depth lower than d n (Keller & Bliesner, 2000). Therefore, high irrigation uniformity is an essential factor for obtaining high irrigation efficiency and, consequently, greater crop response to irrigation (Darko et al, 2017;El-Wahed et al, 2015;Mantovani et al, 1995). Efforts to improve the irrigation uniformity provide better effects on the crop yield and on the financial return compared to increasing the amount of applied water, especially in regions with water scarcity (Nascimento et al, 2019).…”

Irrigation can provide significant agronomic and financial returns on agricultural activity. The maximization of the benefits obtained from irrigation depends, among other factors, on the water use efficiency, which is intrinsically related to application uniformity. For the sprinkler method, the irrigation uniformity assessment is based on results of labor-intensive field tests in which the two-dimensional water distribution pattern is measured in a grid of catch cans. The aim of this study was to evaluate a simplified methodology for determining the irrigation uniformity using water depth distribution data of a single sprinkler head in operation, positioned at the intersection of two diagonal alignments containing regularly spaced catch cans. Three methods to simulate the spatial water distribution on the alignments were evaluated: linear interpolation (LI), cubic spline (SC) and second-degree polynomial regression (PR). Each of these methods were associated with a procedure to calculate the two-dimensional spatial water distribution. The adequacy of the LI and SC modeling methods was verified by using the Wilcoxon-Mann-Whitney test (p-value < 0.05) applied to the data of the field tests. Mean values of the coefficient of efficiency equals to 0.771 and 0.785 were obtained for the LI and SC methods, respectively. The PR method underperformed the others.

“…The factors influencing the hydraulic processes like water infiltration and uniformity of water distribution need to be considered to improve efficiency of irrigation methods (Hlavek, 1992). The uniformity of water distribution can be achieved to a greater extent using sprinkler and drip irrigation systems (Varlev, 1976;Stern and Bresler, 1983;Seginer, 1983;Moteos et al, 1997;Li and Rao, 2000;Dechmi et al, 2003;Zhang et al, 2013;El-wahed et al, 2015). However, initial cost required to install micro-irrigation systems restrict its use for closely spaced crops viz.…”

Irrigation experiments were conducted during November to April under wheat crop in the winter season of 2012-13 and 2013-14 in the farmerâ€™s field at Galibkhedi village located in Karnal District, Haryana State, India. In the study, collapsible multi-outlet pipe (MOP) along with single outlets pipe (SOP) was tested in farmerâ€™s field under wheat cultivation. Irrigation was carried out in five treatments including tillage (T) with SOP and MOP; zero-tillage (ZT) with SOP and MOP, and furrow irrigation with raised bed (FIRB). Iso-time profile of waterfront spreading and advance indicated that irrigation water distribution was uniform under the plot irrigated using MOP as compared to plot irrigated using SOP. In addition, water distribution was uniform under zero tilled plots as compared to tilled plot. Results implied that MOP has several advantages over SOP in terms of application efficiency (AE) and uniformity of water distribution. Average application efficiency for the first study year was found to be in the order of ZT-MOP (82.41%) > FIRB (76.79%) > ZT-SOP (75.25%) > T-MOP (74.85%) > T-SOP (69.79%). Average application efficiency for the second study year was found to be in the same order as first year with some deviation in values. In the second year values of mean application efficiencies were ZT-MOP (82.58%) > FIRB (77.13%) > ZT-SOP (73.04%) > T-MOP (69.65%) > T-SOP (66.13%). Overall, this study concludes that irrigation under wheat crop using collapsible multi-outlet pipe (MOP) with zero tillage practices is a suitable option for surface irrigation that accomplishes uniform distribution of water with higher application efficiency.
