“…As expected the effect of the interaction on both ear length and diameter (Table 6), the highest values (22.6 and 5.10 cm, respectively) were obtained with T12 (50%Min-N+50% Org-N + Bio-N) plus zinc-nano (Kume et al, 2021).…”

Large fluctuations in the weather come within the climate change crisis in Egypt and could lead to an irreversible change in the environment. As a result of these changes, the production of agricultural crops that are not accustomed to such a climate is declining. Significant warming has been manifested over the past 30 years, with average annual temperatures increasing by 0.53°C per decade. So, a field experiment was executed during the two consecutive summer seasons of 2021 & 2022 inside the Nile Delta of Egypt at the experimental farm of Tag El-Ezz research station, ARC, Dakahlia governorate, (located at 30o 59\ N latitude, 31o 58\ E longitude´) to investigate the influence of applying three different combinations of N fertilizer sources as mineral, organic and biological fertilizers and Zinc compounds on yield and its components of corn (Zea mays L.) plants (white single cross-type Giza 128). Each experiment contained twelve treatments which were the combinations of the three different nitrogen source combinations (100% of the recommended Min-N, 50% Min-N+ 50% Org-N and 50% Min-N + 50% Org-N +Bio-N)) and four sources of Zinc forums (Control-without), zinc sulfate, zinc-EDTA and zinc-nano). The experimental statistical design was a split-plot system with three replications. The Ntreatments were in the main plots, whereas, Zinc forms occupied the sub-plots as a foliar application. The results revealed that the application of Min-N with Org-N in combination with Bio-N resulted in increasing yield and yield components significantly. Application of 50% Min-N+ 50% Org-N combined with Bio-N produced higher length of the ear (cm),, grains weight ear -1 , grain yield & biological yield of maize. Foliar application with zinc improved yield and its components of maize and higher length of the ear, 100-grain weight, grains weight per ear, grain yield and biological yield as compared with the control. The best results were observed with ZnO nanoparticle treatment (ZnO-NPs). So, it can be said that fertilizing maize plants with 50%Min-N+ 50% Org-N+ Bio-N combined with spraying plants with zinc nano had a significant impact on yield and its components of maize.
