Pemberian Pupuk Kalium pada Sistem Tumpangsari Tanaman Jahe dan Jagung dengan Jarak Tanam Berbeda
Abstract: This research aim
was to know the dose of potassium fertilizer and different plantspacing of
ginger between corn plants to increase produce the ginger crop and cornwhich
conducting at multiple cropping system. This research was conducted usingthe
Completelly Randomized Block Design of the planning (RAK) factorial con-sisted
of 2 factor and 3 repeated. The first factor was potassium fertilizer
including0 kg KCl/ha, 100 kg KCl/ha, 200 kg KCl/ha, and 300 kg KCl/ha. The
second factorwas different plant spacing of ginger crop including 25 x 35 cm,
30 x 40 cm, and35 x 45 cm. Every treatment and replication was 2 x 2 m.
Parameter observed wereheight of ginger crop and corn crop, relative growth
rate of ginger crop and corncrop, number of ginger crop, heavy of wet ginger
crop, heavy of dry ginger crop,the time of appear that flower of corn, the wind
of corn crop, heavy of dry corncrop, and heavy 100 of grain. Analysis was
continued by Duncan New MultipleRange Test the (DNMRT) of level 5 %. Research
indicate that the giving of potas-sium fertilizer with dose 100 kg/ha and 25 x
35 cm of ginger crop spacing representthe best treatment to increase produce
the ginger of each crop and that the giving ofpotassium fertilizer with dose
300 kg/ha and 30 x 40 cm, 35 x 45 cm represent thebest treatment to increase
produce the corn of each crop.
