Abstract
Pepper is a crucial fruit and vegetable that
is grown for commercial purposes due to it pungency. This
study therefore examined the impact of goat, and pig dung on the pungency of
habanero, and chili, pepper varieties while taking into account the effects of
seasons (wet and dry seasons). The study was carried out in the Department of
Plant Science and Biotechnology, Rivers State University, Port Harcourt,
Nigeria. Pepper seeds were nursed, and later transplanted to different
perforated 10L polythene bags containing soil that was amended with different
rates of goat, and pig dungs. The fruit pungency was measured at ripened stage
by using spectrophotometric method. Results showed that: habanero had the
highest pungency (13,519.89±1.32), than chili (893.93±0.24), for habanero
pepper, the highest pungency (28,325.60±1.31) was recorded in the soil amended
with 300g of goat dung during the dry season, while the least (0.00) was
recorded in the control during the wet season; for chili pepper, the highest
pungency (2,369.75±1.22) was recorded in the soil amended with 300g of goat
dung during the dry season, while the least (0.00) was recorded in the control
during the wet season; The application of goat, and pig dungs increased the
pungency of the various pepper varieties, with the wet and dry seasons having a
substantial impact. The use of goat dung is highly recommended in situations
where raising the pungency level is the aim of pepper cultivation.
