reduced when cowpea was sown at the time of
transplanting pepper into pineapple in the rainy season
of 2011 (Table 5). The weight of pineapple fruit +
crown was not significantly influenced by the date of
sowing cowpea into pineapple-pepper intercrops in the
late season of 2011. Conversely, the values of this
parameter reduced significantly when cowpea was
sown at the time of transplanting pepper into
