Hydro-priming is a seed pre-treatment technique, explored as a potential factor influencing the early seedling development of different maize cultivars. This study investigates germination rates, seedling vigor, and other growth factors in a planned way to help researchers identify the best hydro-priming times for different types of maize. This will lead to better farming methods and higher crop yields. The objective of this study is to compare the growth parameters of different maize varieties under various seed priming durations. In this regard, the laboratory experiments investigate the influence of hydro-priming treatments such as P0, P1, P2, P3, and P4 by 0, 3, 6, 9, and 12 h, respectively. Results showed that all priming methods upgraded germination parameters. The maximum seed germination (%) of different maize varieties, i.e., P4040 (95.2%), P1429 (94.1%), and Akbar (88.2%), were recorded for the P4 treatment compared to the control. At the same time, the greater shoot (46.4%) and root (286.9%) dry matter were noted in treatment P4 (12 h) in the P4040 variety than in the P0 treatment. Notably, the treatment involving the application of P4 (12 h) treatment-primed seed of maize seedlings is related to greater root shoot fresh and dry matter. It is suggested that this research could have practical implications for optimizing agricultural practices and improving the overall productivity of maize crops.
