The effect of chemical fertilizer on growth performances of Arachis hypogaea under two light intensity on bris soil.

In this study, Beach Ridges Interspersed with Swales (BRIS) soil which was ahigh sandy texture had been used to measure the germination of groundnut. They were poor both in physical and chemical properties likes low fertility, lack of nutrients, high permeability, high soluble salts and poor water holding. The objective of this study was to determine the effects of chemical fertilizer and the most suitable light intensity for groundnut production on the BRIS soil. This experiment was laid out in a Split-plot design with two treatments which consisted of BRIS soil and BRIS soil with chemical fertilizer and was placed under two different light intensity. Growth and yield parameters such as height, diameter, number of branches and leaflets and biomass production were assessed. To grow crops successfully, these soils must be improved. These results shown that addition of NPK fertilizer to BRIS soil improved BRIS soil health and increased groundnut production. Adding NPK fertilizer to BRIS soil significantly increased the nutrient to the soil and production of the groundnut.
