PERTUMBUHAN DAN HASIL TIGA VARIETAS CABAI MERAH (Capsicum annuum L.) DENGAN APLIKASI KALIUM SULFAT
Abstract: This research was
conducted in the experimental field of Agricultural Faculty of North Sumatra
Muhammadiyah University with a height of ± 27 meters dpl, held in july - nov
2012. This study aims to determine the best dose frequency of k2so4 on growth
and the result of red chili varieties. This research was conducted using the
split plot design with two factors; the varieties factor as the main plot with
3 kinds of varieties, named, V1 = TM 999, V2 = Lado, V3 = Landung; and the dose
and frequency factors of k2so4 as subplot with 10 stages of treatment which is:
K0 = 0, dose = 1.5 g / liter frequency 6 x (K1), 9 x (K2) and 12 x (K3), dose =
3 grams / liter frequency 6 x (K4), 9 x (K5) and 12 x (K6), dose = 4.5 g /
liter frequency 6 x (K7), 9 x (K8) and 12 x (K9). The fertilizing was cunducted
in the morning at 06.30 am - 08.30 am. The measured variables are plant height,
numbers of chlorophyll, age of flower, numbers of flower, the percentage of
deciduous fruit, weight of fruit/plot. Varieties show significant differences
in plant height, numbers of chlorophyll leaf, age of flower, numbers of flower,
the percentage of deciduous fruit, numbers of fruit, weight of fruit, weight of
fruit per plot, moisture content and storability. Dose and frequency treatment
of potassium sulfate is significantly different from controls. The best dose
and frequency of this research is K9 which is 4.5 g/liter k2so4 with 12 time
frequency during the growing season in TM 999 and Landung while the varieties
of Lado are at dose of 3 g/liter of water with 12 times in giving (K5).
