IntroductionWheat (Triticum aestivum L.) is the leading food crop in the world. It ranks first among the main four crops namely: rice, maize and barley. It occupies about 30% of the world cropping area (FAO, 2016). In Egypt, wheat is considered one of the more strategic grain crops. The cultivated area of wheat reached about 3.1 million faddan in 2015-2016 giving 8.2 million tons of grain, with a national average of about 18.1 ardab/fad. However, the local consumption in the same year surpassed 14-15 million tons. Every year, Egypt imports about 55% of its wheat consumption to face the great needs of the high population increment , hectoliter, density, root length, and protein percentage in both seasons. Gemmeiza 11 superior the other cultivars for both of grain and straw yield and for EC in 2015/16 and for shoot length in both seasons. Giza 168 recorded the highest values for density in both seasons. Increases in nitrogen fertilizer increased significantly number of days to heading and maturity, plant height, spikes/m 2 , grain/spike, grain and straw yield, while decreased 1000 grain weight. There were significant differences among N levels treatments regarding EC, hectoliter weight, density, root length, shoot length, dry weight and protein percentage in both seasons. Application of 100 kg N/fad resulted in higher values than other treatments for all traits except EC in both seasons were decreased.

Managing N inputs in wheat production systems is an important issue in order to achieve maximum profitable production, and minimum negative environmental impact. The aim of this investigation carried out in dry land farming in the Vojvodina province (Serbia) was to estimate the effects of different N fertilization levels (0, 75, and 150 kg N ha -1 ) on some quantitative traits, rain-use efficiency (RUE), N agronomic efficiency (NAE), and N use efficiency (NUE) in two Serbian winter wheat (Triticum aestivum L.) cultivars 'Pobeda' and 'Renesansa'. 'Pobeda' had higher grain yield (4437 kg . NAE and NUE declined at high N rates. Based on the results of this study, farmers should be advised that the use of large amounts of N increases production costs and reduce the economic benefits. The increase in wheat production is possible by selecting adapted genotypes with improved NUE.

The Changes in Yield Response Factor, Water Use Efficiency, and Physiology of Sunflower Owing to Ascorbic and Citric Acids Application Under Mild Deficit Irrigation

Under arid and semi-arid climates, adopting the appropriate tools for alleviating water deficit impacts is a critical factor that affects the physiological characteristics and yield of sunflower. Therefore, in order to find promising field practices in sunflower cultivation, the strip plots design in randomized complete block arrangement was used to examine the effects of two irrigation regimes as 100% (FI) and 85% (DI) of crop evapotranspiration and five antioxidant treatments on physiological and agronomic traits, yield response factor, and irrigation water use efficiency (IWUE) of sunflower. The antioxidant treatments involved two rates of ascorbic acid (150 and 300 mg L−1) and two rates of citric acid (250 and 500 mg L−1), in addition to the check treatment (tap water). The study was conducted for two growing seasons of 2019 and 2020 at the Experimental Farm of Ain Shams University, Egypt, located in a semi-arid environment. Findings showed that exogenous application of higher rate of ascorbic acid, i.e. 300 mg L−1 with FI exhibited the highest increase of chlorophyll a, chlorophyll b and the lowest proline content compared to other interaction treatments. Seed yield was significantly higher with FI plus ascorbic acid 300 mg L−1 and DI plus ascorbic acid 300 mg L−1 treatments than with their counterpart check treatment in both growing seasons. Under DI, IWUE was improved with antioxidant-treated plants compared to untreated plants. Yield response factor as an indicator of crop tolerance to drought was higher than the unit (> 1) under all ascorbic acid and citric acid levels. It could be concluded that ascorbic acid and citric acids partially mitigated the reductions in growth and yield caused by low water supply. However, yield response factor demonstrated that the crop is still sensitive to drought. Thus, other applicable patterns should be adopted to increase the yield potential of sunflower for counteracting the adverse impacts of drought.
