ABSTRACT
V
Field trials were sited on soils belonging to the Ultisols family at
three sites (Pokuase Agric. Research Station, Parrico and Silwood farms)
within the southern forest-savanna ecotone to determine the influence of
different N/K20 fertilizer ratios on the yield and quality of pineapple.
A split-plot design was used with two (2) P levels on main plots and six
(6) N/K20 fertilizer ratios on sub-plots was used.
Soil samples were taken from the three (3) sites. Leaf samples of
the pineapple crop were also taken at the 6th, 10th, and 12th months for
the different stages during the plant growth. From the physical and
chemical properties of the soils, it was observed that the soils do not
differ in their fertility status. However, from the rainfall distribution,
Parrico and Silwood sites were observed to be wetter than Pokuase.
Except for significant treatment effects (P< 0.05) on leaf per cent K
at Pokuase and per cent Ca and N at Parrico, there was no other significant
treatment effect. There was, however, a general increment in the
concerntrations of leaf K, N, Ca and Mg and decrease in the concerntration
of leaf P through the growing period.
Mean fruit weight at Pokuase was lower than those at Parrico and
Silwood. Most of the fruits from Parrico and Silwood were however heavier
than the recommended sizes for the export market. Fruits from all sites
were of good quality in terms of
acidity and sugar content. Some significant correlations were obtained
between leaf nutrient concerntrations at various stages of growth and mean
fruit weight, acidity and sugar content of the fruits.
