Abstract
An experiment was carried out during 1989 wet season at
the Horticultural Field Unit of the Institute for Agricultural
Research, Samaru, Zaria, to study the effects of two
transplantings dates (5th July 1909 and 26th July 1989), three
planting densities (20,000, 40,000 and 60,000 plants/ha) and
four nitrogen levels (0, 30, 60 and 90 kg N/ha) on the growth
and yield of garden egg.
Transplanting on 5th July 1989 significantly increased
number of leaves per plant and fruit diameter while fruit
yield per plant, leaf area index and total dry weight per
plant were significantly decreased. The rest of the parameters
tested were not significantly influenced by transplanting on
different dates.
Increasing plant population significantly decreased stem
diameter, number of branches per- plant, number of leaves per
plant, plant leaf spread, leaf dry weight, stem dry weig/nt and
total dry weight. Similarly, fruit fresh weight, fruit dry
weight and number of fruits were significantly decreased with
increase in plant population. Number of leaves per m2, leaf
area index, fruit dry weight per plot and total yield per
hectare were however, significantly increased with increase in
plant population.
Nitrogen application significantly increased all the
growth and yield parameters measured over the control in all
the weeks studied. Fruit fresh weight, fruit dry weight per
plant. Fruit dry weight per plot and total yield per hectare
were progressively increased each additional 30 kg N/ha up
to 90 kg N/ha. Total fruit yield per hectare was significantly
increased from 4.19 tons in the control to 7.37. 9.98 and 11.55
tons by the application of 30, 60 and 90 kg M/ha respectively
which correspond to 76,133 and 175% inoreasa owr the control
respectively.
Significant interactions were recorded between the
factors on most of the parameters tested.
Similarly, significant and positive correlation was
obtained between fruit yield nd all parameters tested except
number of days to 50%flowering which was negatively correlated
with fruit yield.
