“…The fresh and dry weight was much higher than other studies, as, in most studies, the fresh weight of different basil cultivars grown in the field was in the range of 240.2-1105.9 g m −2 and dry weight was in the range of 47.9-202.8 g m −2 [12,18,20], and in our study, fresh weight was in the range of 378.5-4357.5 g m −2 and dry weight in the range of 65.8-922.5 g m −2 . It is known that the fresh and dry weight of basil are affected by a number of factors such as irrigation, fertilization, sowing time, plant density, weather conditions (temperature, humidity), and genotype [12,18,33,34]. The fresh and dry weight that was found in the present study was higher than other studies because of the higher growth of the basil plants as the plants reached 90 cm in height, possibly due to better growth conditions.…”

Drought is one of the major yield constraints of crop productivity for many crops. In addition, nowadays, climate change creates new challenges for crop adaptation in stressful environments. The objective of the present study was to determine the effect of water stress on five cultivars of basil (Mrs Burns, Cinnamon, Sweet, Red Rubin, Thai) and whether water use efficiency (WUE) can be increased by using the appropriate cultivar. Water stress affected the fresh and dry weight and also the partitioning of dry matter to leaves, flowers, and stems. Also, there are cultivars, such as Mrs Burns and Sweet, which were not affected by the limited amount of water and continued to produce a high amount of dry matter and also showed high essential oil yield. Essential oil content was not affected by the irrigation; however, essential oil yield was affected by the irrigation, and the highest values were found at Mrs Burns. The water use efficiency was affected by the cultivar and irrigation level, and the highest was found at Mrs Burns. The results show that using appropriate cultivars basil can achieve higher WUE and allow saving water resources and utilizing fields in areas with limited water resources for irrigation.

“…We have shown that the primary reasons are decreased energy output and a larger proportion of labor input in the intercropping system. There is thus an urgent need for suitable machine research and technical development to decrease labor inputs in intercropping systems, which should take place alongside ongoing research into other management practices to improve the sustainability and potential of intercropping systems, such as improved irrigation water use efficiency methods [61] and different tillage systems [62].…”

Monocropping systems, which currently dominate China’s major grain production regions, contribute to resource scarcity and environmental pollution. Intercropping has the potential to improve resource use efficiency. However, prior studies of intercropping systems have generally focused on ecological, economic, and social consequences. Here, we make a comparative ecological sustainability analysis on energy capture and efficiency of maize monocropping and maize–soybean intercropping systems through emergy evaluation based on field experiments performed from 2012 to 2014. We find that maize monocropping shows higher sustainability than maize–soybean intercropping in the North China Plain at present. Quantitative results indicate that for maize monocropping, the emergy yield ratio (EYR) and emergy sustainability index (ESI) are 13.7% and 21.1% higher than that of intercropping systems, and the environmental loading ratio (ELR) is 7.3% lower than that of intercropping systems. To further test, we applied three levels of nitrogen fertilizer in intercropping systems (120 kg ha−1, 180 kg ha−1, 240 kg ha−1), and find that a reduced rate of N fertilizer for intercropped system leads to higher sustainability (ESI 5.3% higher) but still lower sustainability than maize monocropping. Key drivers of the different sustainability outcomes are decreased energy output and a larger proportion of labor input associated with intercropping systems.

Developing seeds with a high level of tolerance against salinity and water shortage scan guarantee best seedling establishment in arid and semi-arid agricultural lands. This three-year field, laboratory and greenhouse study proposes the surfactant application to effectively prevent the detrimental impacts of severe environmental conditions on the development of parental plants. The germination rate of six parental seeds of berseem clovers (Trifolium alexandrinum L.) from I 100 (100% irrigation water)/I 100 +s (irrigation water with surfactant, s), I 75 /I 75 +s and I 50 /I 50 +s treatments are studied under seven osmotic salinity potentials (0, -0.2, -0.4, -0.6, -0.8, -1, and -1.2MPa). Plants from seeds developed by surfactant in full and moderate limited irrigation (I 100 and I 75 ) show a favorable germination percentage when under saline stress treatments of -0.4 and -0.8MPa. The highest seedling lengths of 10.2 and 10.3cm were achieved for the seeds produced from I 75 and I 100 +s treatments, respectively. Utilizing the surfactant across all field treatments had a positive effect on the weighted germination index compared to the counterpart treatment. In addition, Seedlings from seeds treated by surfactant in the germination tests have higher shoot/root ratios, which show the efficiency of surfactant application in promoting a better root and shoot development under saline/drought stresses. Core ideasa) Surfactant application enhanced parental seeds tolerance against salinity conditions. b) Seeds developed by severely limited irrigation (I 50 ) had a higher G% (75%). c) Highest seedling lengths (10.2cm) obtained from plants treated by I 75 + surfactant treatment. d) Shoot/root ratio enhanced by surfactant application under salinity stress.
