Effect of Phosphorus fertilizer on growth and yield of cowpea

                         i.            Abstract

Four types of soil are found in Liberia. Latosols of low to medium fertility occur in rolling hill and cover about three-fourths of the total land surface. Shallow, coarse lithosols, in the hilly and rugged terrain, cover about one-eighth of the land. Infertile regosols, or sandy soils, are found along the coastal plains they are deficient in nitrogen and phosphorus, which retard the growth and yield of crops. Therefore, a study was conducted in the wet season of 2017 at the Cuttington University agriculture training center to evaluate the effect of phosphorus on the growth and yield of cowpea. Treatment consisted of five (5) rates of phosphorus (0, 0.5, 1.0, 1.5, 2.0, kg/beg) combined with one variety of cowpea (IT99K-573-2-1) and laid out in a randomized complete block design (RCBD). Results showed significant response to applied P on pods per plant, grain and Stover yield and 50-seed weight with highest response to the application of 2.0 kg/beg 5. From this study it can be concluded that cowpea yield when applying P it could be recommended for higher yield of cowpea.
