“…Yadav and Dhanai (2017) and Attia et al (2018) stated that plant height increased significantly with the increasing doses of N fertilization. These findings are consonance with the reports of Amjed et al (2011), Chibsa et al 2016and Gangwar and Lodhi (2018). The interaction between irrigation and Nlevels on plant height had a significant effect in both seasons.…”

“…The increase in spike length may be attributed to the better utilization of nutrients using the adequate moisture, which helps the crop to better utilize the nutrient and made the plant more efficient to express its potential in photosynthesis activity and effect to increase length of spike. Many authors reported that spike length increased by increasing available soil moisture (Ahmed and Sherif, 2014, Teama et al, 2016, Beyenesh and Nigussie, 2017, Attia et al, 2018and Gangwar and Lodhi, 2018.…”

“…Suitable scheduling of sprinkler irrigation is critical for operative water management in crop production, particularly under conditions of water scarcity (Pereira et al, 2002). Decreasing the irrigation requirements from 100% to 50% significantly decreased most of growth characters, yield and its components, protein while, water use efficiency significantly increased (Abdelraouf et al, 2013, Mansour et al, 2016and Gangwar and Lodhi, 2018. Increasing irrigation amounts up to 100% of irrigation requirement significantly increased grain yield (Teama et al, 2016), while WUE and IWUE decreases with increasing amount of irrigation water (Beyenesh andNigussie, 2017 andEissa et al, 2018).…”

Tow field experiments were carried out at the Experimental Farm of the Water Studies and Research Complex (WSRC) Station, National Water Research Center, in Abu Simbel, Toshka Region, Egypt during two winter seasons 2015-16 and 2016-17. The main objectives were to study the effect of different irrigation levels [A 1 =100% of crop water requirements (ET crop), A 2 =80% ET C and A 3 =60% ET C ], three rates of nano-fertilizer (lithovit) (B 1 =0, B 2 = 200 and B 3 =400ppm), three levels of nitrogen fertilizer (C 1 =60, C 2 =80 and C 3 =100 kg N fed-1) and their interactions on yield and its component, water use efficiency (WUE), fertilizer use efficiency (FUE) and quality of durum wheat plants. The experimental design was a strip-split plot with three replications. The tested agronomic traits were: plant height, No. of tillers m-2 , spike length, No. of grains spike-1 , 1000-grain weight, grain yield, water use efficiency (WUE), irrigation use efficiency (IWUE), fertilizer use efficiency (FUE) as well as protein and ash content, hectoliter weight and Hegberg falling number. The results indicated that the irrigation levels, nano-fertilizer concentrations and N-levels had significant effects on most yield component, water parameters, fertilizer use efficiency and quality of wheat plants in both seasons. Increasing irrigation levels from 60% to 100% increased all agronomic traits and FUE, but WUE, IWUE and falling number were decreased. The treatment of 400 ppm nano-fertilizer produced high values of all yield parameters, water relation, FUE except falling number. Increasing N-levels from 60 to 100 kg N fed-1 increased all studied traits, but FUE and falling number were deceased. The maximum grain yield (2192.4 and 2251.6), (2026.8 and 2075.7) and (1904.3 and 1964.3 kg fed-1) were produced when 100% of irrigation water, 400ppm of lithovit and 100 kg N fed-1 were applied in the two seasons, respectively. Based on the obtained results, it could be concluded that highest irrigation level of 100%, nano-fertilizer concentration of 400 ppm in combination with Nlevel of 100 kg fed-1 is suitable for Toshka climatic conditions to increase the grain yield and quality of wheat (Triticum durum L.).

“…The reduction in these traits was might be due to the lower amount of water supply in root zone, which caused a depression in plant growth and photosynthesis activity, and hence reducing in dry matter production and grain yield. Similar results were reported by Dong et al (2011), Attia et al (2016, and Gangwar and Lodhi (2018). Results have also indicated that high level of Nitrogen fertilization has significantly affected wheat grains yield and its traits in both seasons (Table 1).…”

“…Results have also indicated that high level of Nitrogen fertilization has significantly affected wheat grains yield and its traits in both seasons (Table 1). The role of nitrogen was may be due to improving plant growth and chlorophyll content, which reflected on yield and its components (Zewail, 2007;Abdelkhalek et al, 2015;Attia et al, 2018;and Gangwar and Lodhi, 2018). In addition, the combined effect of water stress and nitrogen levels was also effective on yield and yield characteristics during both seasons.…”

Water stress and nitrogen deficiency are two constraints that negatively affect growth and productivity of wheat plants. Moreover, the interaction between these two stresses could affect the susceptibility of wheat plants to insect attack. In order to examine the influence of drought stress and nitrogen fertilization on piercing-sucking insect pests, the population abundance of four cereal aphid species; English grain aphid Sitobion avenae, wheat aphid Schizaphis graminum, Bird cherry-oat aphid Rhopalosiphum padi, and corn leaf aphid Rhopalosiphum maidis has been monitored in two water treatments (water stress and well-watered) and two nitrogen levels (120 and 180 kg N ha -1 ). Results revealed that S. graminum was the most dominant specie in all treatments, followed by S. avenae. The population of all aphids tends to increase in the second half of the season coinciding with the emergence of wheat spikes. Stressed-wheat plants attracted more aphids, especially when water deficit synchronizes with an increase in N fertilization. Aphids vigorously thrive better on stressed plants amended with high nitrogen level. Contrary, the lower infestation rate was observed in well-watered plots with lower nitrogen rate. Plant characteristics, such as days to heading, plant height, and chlorophyll content were significantly decreased in drought-stressed plants, while higher N rates increased such parameters. Grain yield and its components were reduced with drought stress and reduced nitrogen fertilization. The current study advocates avoiding severe drought concurrently with an increasing in nutritional augmentation which it might contribute in an increase in insect pest infestation and decreasing in wheat plant traits.

T HE effects of two levels of drought stress (25% and 50% of FC) and the control (75% FC) on the growth, some physiological processes and some metabolites in wheat (Triticum aestivum, cv. Masr 2) at seedling (30 days), vegetative (65 days) and yield (160 days) stages were studied. The ameliorative effects of the foliar spray for the harmful effects of drought by the bio-stimulant yeast extract (10%) or the mineral fertilizer lithovit (3.8%) were also studied. The results showed that both levels of drought stress decreased all of the measured growth criteria and chl a and chl b at both growth stages. The foliar spray with yeast extract or lithovit resulted in the alleviation of these inhibitory effects. Carotenoids increased with drought stress but decreased using both foliar spray treatments. Carbohydrates and total soluble proteins decreased under both drought levels, but using yeast extract or lithovit treatment alleviated these effects. Higher activities of catalase, peroxidase and ascorbic oxidase were recorded under the two stress levels, while yeast extract and lithovit treatments inhibited them. At yield stage, both drought levels resulted in severe reduction in all yield parameters, carbohydrates and total soluble proteins contents in the produced grains. Foliar spray with yeast extract or lithovit improved all the measured parameters of yield and increased the contents of the metabolites in the grains. Although lithovit was slightly more effective than yeast extract, the latter treatment seems preferable as it is a natural product with no apparent residual effects on plants and soil.
