Abstract

Light is of great importance to man, animals and plant, as the growth of plants upon which man depends cannot be accomplished without light. The effect of different frequencies of the visible light in the electromagnetic spectrum on snails (Archachatina marginata) was investigated. The analysis involves both the volume (size) and weight changes for a period of 16 weeks. The dark condition yielded the maximum size gain, followed by the yellow light. The blue light on the other hand produces the highest weight gain, followed by the dark condition. Yellow light recorded weight loss on the snails. We observed that natural daylight inhibits snails’ growth rate. Poor correlation between snails’ size and weight gain (C = 0.071) suggests that weight gain in snails is not necessarily a function of size. Our results compares well with previous observations that snails grow faster under dark condition. We proposed that more of these studies be initiated over a longer experimental observation period for enhanced and sustainable agricultural productivity.
