APLIKASI KOMPOS KULIT BUAH KAKAO DAN PUPUK UREA, TSP DAN KCl TERHADAP PERTUMBUHAN TANAMAN JAGUNG MANIS (Zea mays Saccharata Sturt)
Abstract: Sweet corn is one of
the crops that has a fairly large role in provide the nutritional needs of the
people. One of the effort that can be do
to improve the growth and production of sweet corn is fertilization. The aim of
this research are to determine the effect of interaction of cocoa peel’s
compost and Urea, TSP and KCl fertilizer on growth and yield of sweet corn and
get the best dose of treatment. This research was conducted experimentally by
using Randomized Design Group (RDG) factorial with two factors namely cocoa
peel’s compost treatment consist of 4 levels namely 0 ton/ha (K0); 2,5 tons/ha
(K1); 5 tons/ha (K2); 7,5 tons/ha (K3) and Urea, TSP and KCl fertilizer treatment
consist of 4 levels namely (50 kg
Urea; 37,5 kg TSP; 25 kg KCl)/ha (P1); (100 kg Urea; 75 kg TSP; 50 kg KCl)/ha
(P2); (150 kg Urea; 112,5 kg TSP; 75 kg KCl)/ha (P3); (200 kg Urea;150 kg TSP;
100 kg KCl)/ha (P4) with 3 replications. The parameters focus on plant height,
the ratio of editorial root, cob length without cornhusk, the number of rows
and cob weight without cornhusk/plot. The result of this research shows that
the interaction of cocoa peel’s compost and Urea, TSP and KCl fertilizer there
is no real effect to all the parameters. Giving cocoa peel’s compost 7.5 tons/ha and fertilizer (200 g Urea, 150 g
TSP and 100 g KCl)/ha is the best dose of treatment.
