This study was to investigate if residual earthworm products in a soil left to dry up for five months would still be able to stimulate seed germination. Soil pots were treated with different levels of earthworms and planted with Amaranthus seed which grew for 36 days before they were harvested by uprooting. The pots were left to dry for five months simulating the dry season. The levels of germination correlated with the level of earthworm treatments. This suggests that earthworm products survive in the soil during the five months dry season experienced in this part of Nigeria. Leftover earthworm products must therefore be important to seed germination during the early cropping with the first rains before the earthworms populations build up. That the earthworm products improve total germination suggests that they may contain some enzymatic/catalytic component that affects the efficient utilization of the endosperm such that the embryo survives before the depletion of the endosperm. This may be related to the fact that the earthworm produce plant growth hormones that stimulate cell proliferation and elongation in the radicle. Fast development of the radicle ensures stabilization before depletion of the endosperm.
