ABSTRACT

 Two field experiments were conducted at eastern farm of Michael Okpara University of Agriculture Umudike in 2006 and 2007 cropping seasons to determine the optimum plant population of egusi melon (Colocynthis citrullus) (L) O.Ktz) for weed control and yield of sweet corn/egusi melon intercrop. The treatments were laid out in a 2 x 3 x 3 factorial in randomized completer block design (RCBD) with three replicates. There were two cropping systems (sole and intercrop ), three egusi melon planting densities (0, 10,000 and 20,000 plants/ha) and three weeding frequencies (0, l manual weeding 3 weeks after planting (W AP) and two manual weeding at (3 and 8 WAP). The results showed that seed yield of egusi melon was higher with higher egusi plant population in both years whereas sweet com grain yield was not affected by egusi plant population. Yield of sweet com was highest with two wccdings whereas there was no yield difference for egusi melon weeded once or twice. The 20,000 plants per hectare of sole egusi melon population at two manual weedings followed by 20,000 plants/ha egusi intercropped with sweet corn weeded once had the least weed dry matter, indicating efficient low cost weeding management by simple expedient of using biological and cultural weed control strategics. The land equivalent ratio was > 1.0 indicating yield advantages of intercropping system. This showed that sweet com could be successfully intercropped with egusi melon for optimum yield
