PENGARUH PEMBERIAN URINE SAPI DAN PUPUK NPK TERHADAP KOMPONEN PRODUKSI TANAMAN JAGUNG MANIS(Zea mayssaccharata Sturt)DI LAHAN GAMBUT
Abstract: This study aimed to
determine the effect of cow urine and NPK fertilizers, as well as getting the
best dose on production component of sweet corn on peatlands. The research was
conducted on peat types sapric in Experimental Farm, Faculty of Agriculture
Rimbo Panjang TambangDistrict of Kampar Regency and conducted over three months
starting in December 2015 to March 2016. The study was conducted using a
factorial RAL consisting of two factors with the first factor is giving of cow
urine U1: cow urine concentration of 150 ml/l, U2: cow urine concentration of
300 ml/l, U3: cow urine concentration of 450 ml/l and U4: cow urine
concentration of 600 ml/l. The second factor is the NPK fertilizer is P0:
without fertilizer NPK, P1: award NPK 150 kg/ha and P2: award NPK 300 kg/ha.
Data were analyzed statistically using analysis of variance followed by
Duncan's multiple range test at 5% level. Parameters measured were plant growth
rate, production per plot, weight per cob without husk, cob without husk
lengthand diameter cob without husk.The results showed interaction NPK
fertilizer of cow urine and cow urine as well as single factor effect is not
real to each parameter of observation. Giving a single factor NPK showed an
increased rate of plant growth, production per plot, weight per cob without
husk, without husk cob lengthand cob diameter without husk. Increased
production of sweet corn is highest at a dose of 300 ml of cow urine treatment
with NPK fertilizer 150 kg/ha of 6,53 kg/5,25 m2 (equivalent to 5,0 tons/ha),
increased 83% compared with no fertilizer NPK and 150 ml cow urine.
