Effects Of Intercropping Maize (Zea Mays) With Butternuts (Cucurbita Moschata) At Varying Butternut Population Levels On Maize Growth, Yield And Weed Supression

ABSTRACT Intercropping is a cultural technique which gives crops a competitive advantage on weeds therefore contributes to weed management. There is need to choose the plant population which results in weed suppression whilst not negatively affecting the component crops yield. The experiment was set in a Randomised Complete Block Design with 5 treatments which are sole maize crop, maize-butternut intercrops at butternut densities of (30%, 40% and 50% of maize population which is 111...

EVALUATION OF THE POWDER OF Piper guineense AND Pirimiphos-methyl FOR THE CONTROL OF COWPEA STORAGE WEEVILS (Callosobruchusmaculatus)

ABSTRACTThe insecticidal effects of Piper guineense and Pirimiphos-methyl was evaluated on cowpea. The treatments used were P. guineenseat 0.2, 0.4, 0.6, 0.8, and 1g as well as Pirimiphos-methyl at 0.1g per 20g of cowpea seeds, each laid out in Complete Randomized Design (CRD) in the laboratory. Results indicated that P. guineense at 1g   concentration   significantly   (P
