A field experiment was carried out at the Department of Agronomy Experimental Farm, Faculty of Agriculture, Assiut University, during the growing seasons 2017/18 and 2018/19 to study the impact of foliar spray by some Nano Micro-nutrients on grain yield and quality of three cultivars of bread wheat. Randomized complete block design (RCBD) was used in this experiment in three replications using strip plot arrangement. The bread wheat varieties i.e., Sids-1, Sids-12, and Gemmeaza-11 were arranged vertically, while foliar sprays with tap water (solvent as a control) and Iron, Manganese, Zinc, Iron + Manganese, Iron + Zinc, Manganese+ Zinc and Iron + Manganese + Zinc in Nano form at 200 ppm concentration were distributed horizontally. In both seasons, the foliar spray treatment with certain micronutrient nano-particles had a significant impact on grain yield, flour percentage, coarse bran percentage, wet gluten percentage, and dry gluten percentage. As a result, wheat plants sprayed with Fe + Mn + Zn had the greatest average values of the previous traits. Furthermore, the cultivars studied had a substantial impact on the majority of the traits studied. In addition, in both seasons, the Sids-1 cultivar produced the greatest mean values of the most investigated traits. In both the 1 st and 2 nd seasons, the interaction between some micro-nutrients, nano-particles, and cultivars had a significant (P ≤ 0.05) and highly significant (P ≤ 0.01) impact on fermentation time. In this approach, the Sids-12 cultivar, which was sprayed with Mn+Zn in the 1 st season, and the same cultivar when sprayed with Mn or Fe+Zn in the 2 nd season, yielded the most elevated mean values of fermentation time (37.00 and 36.50 minutes within the two seasons).

A field experiment was carried out at the Agronomy Department. Experimental Farm, Agriculture Fac., Assiut Univ., during the growing seasons of 2020/21 and 2021/22 to study the effect of nitrogen fertilizers rates and planting methods on grain yield and its components of six wheat cultivars (bread wheat) (Misr 2, Sids 14, Gemaiza 11, Shandweel 1, Giza 171 and Sids 12). A randomized complete block design (RCBD) was used in this experiment with three replications using strip -plot arrangement. The planting methods (flat, ridges and raised beds) were arranged horizontally, while nitrogen rates (50, 75 and 100 kg/feddan.) were arranged vertically as well as the tested wheat cultivars were dole out in the sub plots. The outcome expressed that Gemmeiza11 cultivar recorded the maximum significant mean values of all examined characters (seed index, weight of kernels per spike, grain yield (ardeb/feddan.) and straw yield (ton/feddan.)) compared with other wheat cultivars examined except the number of kernels spike -1 trait which reacted significantly for Sids 12 in both seasons. Furthemore, the nitrogen application level 100 kg/fed. recorded maximum significant average values of grain yield (ardeb/feddan.) and straw yield (ton/feddan) in both seasons. Also, planting wheat plants on raised beds gained the maximum mean values of grain and straw yields in both seasons compared to other tested planting methods.
