Dampak Pemberian Pupuk Urea Dan Pupuk Kandang Ayam Terhadap C organik, Total Dan Serapan N, Serta Pertumbuhan Tanaman Jagung Pada Inceptisol Asal Kwala Bekala
ABSTRAK
Penelitian ini bertujuan untuk mengetahui dampak pemberian pupuk urea
dan pupuk kandang ayam terhadap C-Organik, total dan serapan N serta
pertumbuhan tanaman jagung (Zea mays L.) pada tanah Inceptisol Kwala Bekala.
Penelitian ini dilakukan di Rumah Kasa, Laboratorium Kimia dan Kesuburan
Tanah, PT. Nusa Pusaka Kencana Analytical & QC Laboratory(Asian Agri
Group) serta Balai Penelitian dan Riset Fakultas Pertanian Universitas Sumatera
Utara. Penelitian ini menggunakan rancangan acak kelompok (RAK) faktorial
yang terdiri dari 2 faktor dengan 3 ulangan faktor I : pupuk urea (U) dengan 4
taraf yaitu : U 0 =0 g/polybag, U 1 =1g/polybag, U 2 =1,5g/polybag, U 3 = 2g/polybag
dan Faktor II : pupuk kandang ayam (A) dengan 4 taraf yaitu :
A 0 = 0 gr/polybag, A1 = 50 gr/polybag,
A 2 = 100 gr/polybag, A3 = 150
gr/polybag.
Hasil penelitian menunjukkan bahwa aplikasi pupuk nitrogen berpengaruh
sangat nyata meningkatkan serapan N tanaman dan nyata meningkatkan bobot
kering tanaman. Pemberian pupuk kandang ayam berpengaruh sangat nyata
terhadap peningkatan pH tanah, N tanah, serapan N, C-organik, tinggi tanaman,
berat kering tajuk dan berpengaruh nyata terhadap penambahan bobot kering akar.
Perlakuan terbaik pada perlakuan pupuk urea U 1 = 1gr/ polybag dan pupuk
kandang ayam A3 = 150 gr/polybag
Kata Kunci
: Urea, pupuk kandang ayam, Serapan N, Inceptisol.

ABSTRACT
The aim of the research was to examine the effect of fertilizer and chicken
manure on C-Organic, total and N uptake and growth of maize crop (Zea mays
L.) on Inceptisol Kwala Bekala. This research was mplemented at Rumah Kasa,
Laboratory of Chemistry and Soil Fertility, PT. Nusa Pusaka Kencana Analytical
Laboratory & QC (Asian Agri Group) and Research Center of the Faculty of
Agriculture, University of North Sumatra. This research used factorial
randomized block design consisting of 2 factors with 3 replications of factor I:
urea fertilizer (U) with 4 dosage levels: U0 = 0 g / polybag, U1 = 1g / polybag,
U2 = 1.5g / Polybag, U2 = 2g / polybag and factor II: chicken manure (A) with 4
dosage levels ie: A0 = 0 gr / polybag, A1 = 50 gr / polybag, A2 = 100 gr /
polybag, A3 = 150 gr / Polybag.
The results show that the application of highly significant fertilizer
improves uptake. The provision of chicken manure was highly significant to the
increase of soil pH, soil N, N, C-organic uptake, plant height, canopy dry weight
and significantly increased root dry weight. The best treatment on urea fertilizer
U1 = 1gr / polybag and chicken chicken fertilizer A3 = 150 gr / polybeg
Keywords: Urea, chicken manure, N uptake, Inceptisol.
