Abstract
A field experiment was conducted during the rainy season (May-August) of 2013 and 2014 at the Kogi State Agricultural Development Project Research Farm, Anyigba, Nigeria to investigate the effect of population density and time of introduction of maize on the yield of melon and maize in a melon-maize intercrop. The experiment was a 5 x 3 split-plot laid in a randomized complete block design with three replications. The result indicated that population density and time of introduction of maize had no significant effect on yield and yield components of melon but significant on the number of maize cobs per plot, cob yield/ha and grain yield of maize. Maize grain yield increased with increase in maize population up to 40,000ha-1. Interaction effect of time of introduction and population density was significant on the grain yield of maize. Competition indices like LER and LEC were at advantage. At each level of maize population density, LER was greater than 1, indicating efficiency of resource use while LEC values were more than 0.25 signifying potential productivity of the intercrop. Both LER and LEC values were highest at 4 weeks after planting melon and at 40,000ha-1 of maize. Keywords: Melon, Maize, intercropping, and planting density
