Precision agricultural (PrA) technology relies on the utilization of special equipment to access real time observations plant health status, chlorophyll, nitrogen content, and soil moisture content. In this research new PrA (i.e., SPAD (Soil Plant Analysis Development), UAV-based NDVI (Unmanned Aerial Vehicle-based Normalized Difference Vegetation Index) were used monitor maize yield based different filed trials in eastern part Hungary. Our study aimed examine specifically measurements for monitoring GY under irrigated rainfed experimental setups Hungary with varied treatment year 2022. The results showed that increased all treatments (14.7 %; p < 0.05) from V6–V8 treatments, decreased significantly (p by 13.9 % (R1) 30.6 (R3). However, implementation irrigation values majority treatments. Also, reveal that, conditions highest value (0.703, 0.642) was obtained V12 (A120 treatment) (0.728, 0.662) Vn treatment). Remarekedly, led significant differences compared none irrigated. On other hand, 120 kg N ha−1 before sowing GY, especially (8.649 Mg ha−1). overall mean 6.256 ha−1, while it 37.2 reached 8.581 0.05). conclusion, will support farmers making informed decisions regarding fertilization strategies timing, which turn maximize minimize risk.
