“…While high biomass production under limited irrigation water availability is an important criterion in selecting the proper forage species, the quality of the forage is also crucial and should be considered in selecting species. When irrigation water is limited, some aspects of forage quality, such as nutritional values, may be compromised 4 . However, the majority of forage quality indices often show some levels of improvement 12 .…”

BACKGROUND Strategies to enhance the efficient use of irrigation water require a major shift in irrigation and cropping systems. It was hypothesized that (i) replacing water‐demanding crops such as corn silage with more drought‐tolerant forages species, (ii) adoption of intercropping instead of monoculture, and (iii) use of alternative irrigation methods, may alleviate the water shortage in semi‐arid regions, while producing high‐quality forage. RESULTS Adoption of drip irrigation (DRIP) and alternate furrow irrigation (AFI) reduced water consumption by 43% and 20%, respectively. Additionally, DRIP produced 11% more biomass than the conventional furrow irrigation. The intercropped ratio of 50% sorghum and 50% amaranth under DRIP maximized forage production and improved irrigation water‐use efficiency (IWUE). Principal component analysis indicated that the DRIP increased the dry matter yield and IWUE, whereas the AFI improved the forage quality. The intercropped ratio of 75% sorghum and 25% amaranth demonstrated the highest yield stability and was considered superior cropping system regardless of the irrigation strategies. CONCLUSIONS DRIP and AFI strategies were effective in reducing water consumption, with DRIP being the most water‐efficient method. Intercropping sorghum and amaranth at a ratio of 50:50 under DRIP resulted in the highest forage yield and IWUE. While sole amaranth had the highest forage quality, intercropping sorghum and amaranth increased dry matter production with better forage quality than sorghum monoculture. Overall, the combination of DRIP and intercropping sorghum and amaranth at a ratio of 50:50 considered as a suitable strategy for improving forage yield and quality, as well as IWUE. © 2023 Society of Chemical Industry.

“…Genotypes with a higher WP under water deficit conditions show more drought tolerance, whereas drought-sensitive genotypes have a lower WP (Tshikunde et al, 2018). The cultivation of a drought-resistant genotype along with irrigation management which includes changing the amount of water consumed in the vegetative and reproductive stages may serve to minimize evapotranspiration and increase water productivity (Balazadeh et al, 2021;Farhadi et al, 2022).…”

“…The area under cultivation for this crop globally is about 164 million ha, of which 0.26% is produced by Iran (FAOSTAT, 2020). In recent years, climate change and the subsequent increase in the incidents and duration of drought have threatened crop production and food security (Balazadeh et al, 2021;Farhadi et al, 2022). Drought stress is one of the most significant factors limiting crop yield, it has different effects at different stages of plant development and profoundly affects agricultural systems and food production (Golzardi et al, 2017;Ashoori et al, 2021;Baghdadi et al, 2021).…”

A field experiment was conducted to evaluate the performance and water productivity of 15 rice genotypes under non-stress and drought-stress conditions in a warm-temperate climate. This study was laid out with a randomized complete block design at two research stations (Abbasabad and Katalom, Iran). Water deficit decreased the grain yield and increased the canopy temperature in all genotypes, but the response of water productivity to drought stress was not the same for the different genotypes. The maximum water productivity in non-stress and stress conditions (0.50 and 0.53 kg m -3 , respectively) were found in landraces. The canopy temperature was a reliable indicator for identifying drought-tolerant genotypes of rice. With each degree increase in canopy temperature, the grain yield decreased by 1 942 kg ha -1 . The biplot analysis demonstrated that landraces were the most suitable genotypes for cultivation under drought-stress and nostress conditions. A principal component analysis based on stress tolerance indices showed that Shastak and Sahel were the most tolerant genotypes to drought stress. Overall, Shastak with a maximum grain yield (4 595 kg ha -1 ), the highest water productivity, and savings of irrigation water by as much as 54% under conditions of drought stress may be introduced as a superior genotype for cultivation under water scarcity conditions and used in future breeding programmes.K e y w o r d s: cultivar, irrigation cut-off, stress tolerance indices, grain yield, water use efficiency
