The experiment was conducted at the Faculty of Agriculture, University of Benin, Ugbowo Campus Benin City Nigeria. The experiment was conducted under rain fed condition during the early cropping season (March to November) of the year 2013.
The experimental design was the Randomized Complete Block Design (RCBD) with yam and egusi-melon as the test crops. The trial consisted of 4 levels of NPK 20:10:10 fertilizer (0, 200, 400, 600kg/ha) with 3 cropping systems and replicated 3 times.
It was observed that yam did well in sole than in intercropping. Average tuber yield of yam in fertilizer treatments was also greater than that of unfertilized plants. Also the average tuber yield and number of tubers were significant. The higher tuber yield of yam2.862t/ha and 2.991t/ha was obtained from 400kg/ha treatment in sole and in intercrop planting system. Higher number of tubers of 21.66 was obtained from 200kg/ha treatment in sole planting system.
The mean value of egusi-melon seed yield in intercrop and sole melon was 0.0513t/ha and 0.0511t/ha respectively. And the mean value obtained from average pods size was 28.97cm for sole and 34.0cm for intercrop. From the experiment, plot which was measured 4x1.5m per sub-plot, the average number of egusi-melon gotten was 34.0 for intercrop and 44.0 for sole.
The application of NPK 20:10:10 fertilizer at 400kg/ha had the greatest influence on the yield of egusi-melon both as a sole and as intercrop. The application of 400kg/ha at 6WAP influenced the pod number.
The application of NPK 20:10:10 at 600kg/ha had the greatest influence on vine length and stem girth of egusi-melon both as sole and as intercrop. Average stem girth of 1.19cm in sole and 1.33cm in intercrop was obtained. Vine length of 154.3cm in intercrop as against 156.3cm recorded in sole planting.
The longest vine and the widest stem girth of yam were obtained at 400kg/ha of NPK 20:10:10 fertilizer. Average vine length of 236.2cm in intercrop and 225.7cm in sole at 8WAP was obtained. Average stem girth of 1.55cm in intercrop as against 1.64cm recorded in sole planting.

practice in which two or more crops are grown together in the field
(Onwueme, 1978). One advantage of intercropping is that it increases
yield: more can be grown on a single plot with intercropping.Intercropping
suppresses weed better than sole cropping. It provides an opportunity
to utilize crops themselves as tools for weed management. In
intercropping more complete crop coverage and high population density
