Abstract

Maize (Zea mays L.) is a vital crop, but its productivity is hindered by soil alkalinity, characterised by high pH levels that reduce nutrient availability. This study explores the potential of calcium carbonate seed priming to enhance the germination and early growth of two maize hybrids, CO-6 and VGI (H) M-2, under alkaline conditions. The experiment involved priming seeds with a calcium carbonate solution and testing them in various alkalinity levels (0, 2, 4, 8, and 10%). Results showed that priming significantly improved shoot growth and root length in both hybrids CO-6 and VGI H (M)-2 exhibited varying levels of tolerance to alkalinity, with primed seeds generally outperforming unprimed seeds in shoot growth and root length. This study concludes that calcium carbonate priming can enhance maize tolerance to alkaline soils, improving overall plant health. Further field studies and biochemical tests are recommended to validate these findings and optimise maize cultivation in alkaline environments. This study offers a workable solution to the problems caused by soil alkalinity in maize cultivation, which advances sustainable agricultural techniques.
