In Egypt, water shortage has become a key limiting factor for agriculture. Water-deficit stress causes different morphological, physiological, and biochemical impacts on plants. Two field experiments were carried out at Etay El-Baroud Station, El-Beheira Governorate, Agriculture Research Center (ARC), Egypt, to evaluate the effect of potassium silicate (K-silicate) of maize productivity and water use efficiency (WUE). A split-plot system in the four replications was used under three irrigation intervals during the 2017 and 2018 seasons. Whereas 10, 15, and 20 days irrigation intervals were allocated in main plots, while the three foliar application treatments of K-silicate (one spray at 40 days after sowing; two sprays at 40 and 60 days; and three sprays at 40, 60, and 80 days, and a control (water spray) were distributed in the subplots. All the treatments were distributed in 4 replicates. The results indicated that irrigation every 15 days gave the highest yield in both components and quality. The highly significant of (WUE) under irrigation every 20 days. Foliar spraying of K-silicate three times resulted in the highest yield. Even under water-deficit stress, irrigation every fifteen days combined with foliar application of K-silicate three times achieved the highest values of grain yield and its components. These results show that K-silicate treatment can increase WUE and produce high grain yield requiring less irrigation.

“…Nano-fertilizers postpone the release of nutrients and extended the period of fertilizer effects. Obviously, there was an opportunity for nanotechnology to significantly affect energy and the environment by enhancing fertilizers 25,26 . Applying nanoparticles (NPs) to plants is beneficial for plant growth and development due to their relatively greater absorbance and high reactivity 27 .…”

Worldwide, maize (Zea mays L.) is considered an important food and fodder crop. compost as a soil amendment and potassium (K) could enhance the maize yield. Therefore, two field experiments were carried out in the two seasons 2017 and 2018 to study the effects of compost at three levels and four forms of potassium fertilization on the yellow maize hybrid 'Pioneer Sc 30N11' yield components. to conduct the field trials, a split plot system in three replications was established. Three compost levels (0, 5 and 10 ton/ha) were in the main plots, and four potassium forms (untreated, nano-potassium fertilizer, humic acid and potassium sulfate) were in the subplots. Plot size was 10.50 m 2 , with 5 ridges with 3 m length and 0.7 m width. The results indicated that the application of compost (as organic manure) and the potassium forms significantly affected the plant height, ear length, grains number/ rows, grains number/ear, 100-grain weight, straw and biological yields, grain protein and K contents in both seasons. Increasing the compost from 5 to 10 ton/ha increased the yield, its components, protein and K contents. The foliar application of nano-potassium followed by humic acid increased all the studied characteristics. The interaction between compost manure (10 ton/ha) and nano-potassium (500 cm 3 /ha) or humic acid (10 ton/ha) recorded the highest mean values for all parameters during both harvest seasons.

“…The advantage for using starch as stabilizing agent beside to its potential power to convert the ions of silver to zero valent silver, is the presence of huge hydroxy groups, that stabilize these formed nanoparticles in nanoform. In our published work [40][41][42][43][44][45][46] , the prepared nanoparticles was extensively characterized via advanced tools. Secondly, As mentioned in the experiment part for the preparation of SiO2NPs, condensation reaction was carried out for this synthesis.…”

Silver nanoparticles (AgNPs) have been emerged as promising alternative to antibiotic in poultry. Herein, silver-dopped silica nanoparticles (SiO 2 @AgNPs) was prepared in powder form, using starch, via chemical reduction and sol-gel technique followed by full characterization. SiO 2 @AgNPs was applied in poultry diet at three doses (2, 4, and 8 ppm/kg diet). The safety of oral dietery supplementation was estimated through evaluation of growth performance, hematological, biochemical parameters, and oxidative parameters of birds. Moreover, the immunohistochemical of all body organs were also examined. Results showed that, SiO2@AgNPs, has no negative effects on growth performance, hematological, biochemical, and oxidative parameters of birds. Moreover, the immunohistochemical examination revealed minimum inflammatory reactions and lymphoid deplesion at level 8 ppm/kg diet. In conclusion, SiO 2 @AgNPs could be considered as a promising and quite safe nano- growth promotor in broilers when added to birds diet upto level 4 ppm/kg diet.
