Abstract
Two experiments were designed to study crop mixtures
involving maize and pepper. Seedling age treatments were
also included. In 1980 at Dangora, pepper was mixed with
maize and cowpea planted in the sequence maize-peppercowpea
under rainfed condition. Three maize spacing
treatments of 360, 270 and 180cm. were used. In 1981 at
Samaru, pepper was intercropped with maize in the dry season
under irrigation. Maize was spaced at 240, 180 and 120cm.
Variability was great in both experiments. In 1980, mixed
cropping had an adverse effect on chilli pepper yield and the
relative yield totals (R Y Ts) were less than 1. In monetary
value, however, mixing was better than sole pepper but not as
good as sole maize. Transplanting at 6 weeks gave higher
monetary return than at 8 and 10 weeks with no significance
between 8 and 10. In 1981, sole pepper had higher monetary
value than sole maize and most of the mixed treatments were
intermediate. For treatments with pepper transplanted at 7
weeks old R Y T was about 1 but for the 94 weeks old transplants
R Y T was 1.3, possibly indicating a benefit from mixing.
The late transplanting time performed better in crop
mixtures but not in sole pepper, though the interaction was
not statistically significant. Leaf cover trends were similar
in sole crop and mixtures but the mixtures generally had
greater leaf cover than the mid-point between sole maize
and sole pepper. Cropping pattern and seedling age had
no effect on the proportion of flowers that set fruits.
Maximum fruit set of 41 - 46% was from flowers opening
103 - 115 days from sowing of pepper.
