Allelopathic effects of aqueous extracts of Lycopodium clavatum and Selaginella uncinata were studied on the seedling growth of Zea mays. To investigate the effects of the extracts on seedling growth, greenhouse experiment was conducted. The plumule length and radicle length were measured for both extracts using a ruler. The result showed that the two extracts had both inhibitory and stimulatory effect on Zea mays radicle growth at different concentrations. Selaginella uncinata extract showed stimulatory effect at 25% and 50% concentrations and inhibitory effect at 75% and 100% concentrations. Lycopodium clavatum on the other hand showed stimulatory effect at 25% concentration only and inhibitory effect at 50%, 75% and 100% concentrations. Radicle length decreased in both extracts with increase in concentration whereas the plumule length increased over the measurement period and also decreased with increase in concentration. The extracts had strong inhibitory effect on radical elongation of seedling than on plumule elongation (Ref: Akpan EN, Denise EM, Ezendiokwelu EL, Anyadike MC. Comparative study of allelopathic effects of aqueous extract of Lycopodium clavatum (L.) and Selaginella uncinata (Desv ex. Poir) on the seedling growth of Zea mays. Discovery, 2018, 54(265), 23-28).
Groundwater study in an area requires the detail knowledge structure and geology. This can be well understood with the help of Geographic Information System (GIS).
Soybean (Glycine max (L.) Merrill) is one of the most important legume crops being introduced into the smallholder farming systems of the Central Highlands of Kenya (CHK) for soil health improvement, income and improved household nutrition.
