A field experiment was conducted at Ibn Al-Bitar Vocational Preparatory School in the Al-Husseiniyah District, located in the northern region of Karbala Governorate. The experiment took place during the spring season of 2022 AD. The objective of the study was to investigate the impact of various concentrations of G-Power ca and spraying dates on the growth and yield of maize. The experimental design employed was a randomized complete block design (RCBD) arranged in a factorial order with three replications. The first factor examined was the different concentrations of the nano fertilizer G-Power ca, specifically at levels of 0, 2, 4, and 6 ml L-1. The second component encompassed three distinct time points for foliar application: spraying at 20 days post-planting, spraying at 40 days post-planting, and spraying at 60 days post-planting. The findings of the study indicate that the application of nano-foliar spraying of G-Power ca at a concentration of 6 ml L-1, two months after planting, resulted in considerably improved outcomes compared to other treatments. This treatment exhibited the highest average values for the characteristics under investigation. Each of the variables in the study possesses distinct characteristics, including plant height (measured in centimeters), leaf area (measured in square centimeters), average number of leaves per plant (measured as leaf.plant-1), average percentage of chlorophyll in the leaves (measured as spad), and total plant yield (measured in kilograms per hectare, denoted as kg.ha1-). These variables were observed and recorded in a sequential manner, with corresponding values of 183, 4209, 14.50, 44.67, and 8012, respectively. Therefore, it can be inferred that the utilization of nano-fertilizer has a major impact on the vegetative characteristics of Maize, resulting in a notable enhancement of the aforementioned qualities
