Abstract
In order to study the response of cucumber to different
Ahmadu Bello University Zaria during the 1992 rainy season. Four
N levels (0 nitrogen levels and planting densities a field trail was
conducted at the Institute of Agricultural Research Farm, Samaru,
, 25, 50, 75kg/ha) and four planting densities
(10,000, 20,000, 30,000 and 40,000 plants/ha) were tested in
factorial combinations. The experiment was laid out in a
randomized complete block design.
Nitrogen application significantly increased fresh and dry
weight of the vines, mean fruit weight, circumference of fruit,
and total yield per ha. The mean fruit weight and yield per/ha
were maximum at 75 kg N/ha. Although values at 75 KgN were not
significantly different from those at 50 KgN/ha, the regression
of yield/ha on nitrogen lof levels was linear (r2= 14.6%)The fresh and dry weight of the vines were reduced but the
fruit circumference, lenght and yield/ha were increased as plant
density was increased from 10,000 to 30,000 plants/ha. The
regression of yield/ha on plant density indicate a linear
response (r2= 23.9%).
The interaction between nitrogen levels and plant density was significant on the fresh and dry weight of vine,increasing
density without applied N had no significant effect on vine fresh
weight and dry weights. Maximum fruit yield/ha was obtained with
40,000 plants/ha at 75 KgN/ha in this experiment. The linear
yield responses to both N and plant density suggest even higher
plant density and N levels. Further work is needed to determine the optimum levels of density and N
