Abstract
This study investigates the effects of varying
concentrations of copper sulphate on the germination and early growth of
soybean (Glycine max) seeds. Copper, an essential micronutrient, plays a
critical role in plant physiological processes but can be toxic at elevated
levels. Soybean seeds were treated with different concentrations of copper
sulphate (0, 25, 50, 75, and 100 ppm) to evaluate germination percentage, mean
germination time, root and shoot length, and seedling biomass over 14 days
under controlled laboratory conditions. Results showed that low concentrations
(25 ppm) of copper sulphate slightly enhanced seed germination and seedling
growth compared to the control, indicating a stimulatory effect. However,
higher concentrations (75 and 100 ppm) significantly inhibited germination rate
and reduced seedling growth parameters, demonstrating copper toxicity. Root
growth was more adversely affected than shoot growth at elevated copper levels,
likely due to direct exposure to copper ions in the growth medium. These
findings suggest that while copper is essential in trace amounts for soybean
development, excess copper sulphate can negatively impact seed germination and
early plant vigour, potentially affecting crop productivity. The study
highlights the importance of managing copper levels in agricultural soils to
avoid toxicity and optimise soybean cultivation.
