Respon Pertumbuhan dan Produksi Tanaman Jagung Manis (Zea Mays Sacharatasturt.) Terhadap Pemberian Pupuk Organik Cair Urine Sapi dan Pupuk Kompos Limbah Kubis (Brassica Oleraceae)

Abstract

Penelitian dilakukan di Kebun Percobaan Fakultas Pertanian Universitas Medan Area yang berlokasi di jalan kolam No.1 Medan Estate, Kecamatan Percut Sei Tuan dengan ketinggian tempat kira-kira 12 mdpl, topografi datar dan jenis tanah alluvial. Penelitian ini dilaksanakan mulai bulan februari sampai mei 2017. Penelitian ini dilakukan dengan menggunakan Rancangan Acak Kelompok (RAK) Faktorial, yang terdiri dari dua faktor perlakuan yaitu :I. Berbagai konsentrasi pupuk organik cair urin sapi dengan notasi (s) yang terdiri dari 4 taraf, yaitu : U0 = Tanpa POC urin sapi (Kontrol) U1 = 250 ml/l air U2 = 500 ml/l air U3 =750 ml/l air II. Berbagai dosis Pupukkompos limbah kubis dengan notasi (K) yang terdiri dari 3 taraf, yaitu : K0 = Tanpa Pupuk kompos limbah kubis (kontrol) K1= Pupuk kompos limbah kubis 1 kg/plot K2= Pupuk kompos limbah kubis 2 kg/plot. Parameter yang di mati dalam penelitian ini adalah: Tinggi Tanaman (cm), Jumlah daun(helai), Panjang Tongkol (cm), Berat Kotor Tongkol (gr) Berat Bersih Tongkol (gr), Berat bersih tongkol per Plot (gr).

Adapun hasil penelitin yang di peroleh dari penelitian ini, yaitu : 1). Perlakuan POC urin sapi berpengaruh nyata terhadap tinggi tanaman, panjang tongkol, berat tongkol kotor, berat tongkol bersih, dan berat tongkol bersih per plot, tetapi berpengaruh tidak nyata terhadap jumlah daun tanaman jagung manis. Semakin tinggi konsentrasi urin sapi hingga 750 ml/l air maka pertumbuhan dan produksi tanaman jagung manis juga semakin baik. 2). Perlakuan kompos limbah kubis berpengaruh nyata terhadap tinggi tanaman, panjang tongkol, berat tongkol kotor, berat tongkol bersih, dan berat tongkol bersih per plot, tetapi berpengaruh tidak nyata terhadap jumlah daun tanaman jagung manis. Semakin tinggi dosis kompos limbah kubis hingga 2 kg/m2 maka pertumbuhan dan produksi tanaman jagung manis juga semakin baik 3). Interaksi perlakuan POC urin sapi dengan kompos limbah kubis berpengaruh tidak nyata terhadap semua parameter yang diamati. Research conducted at the Experimental Garden Faculty of Agriculture University of Medan Area located at the Pool Street No. 1 Medan Estate, subdistrict Percut Sei Tuan with a height of approximately 12 mdpl, flat topography and alluvial soil type. The study was implemented from February to May 2017.

This study was conducted using the group random Design (RAK) factorial, consisting of two treatment factors: I. Various concentrations of organic cow urine liquid fertilizer with notation (s) consisting of 4 levels, namely: I. Various concentrations of organic cow urine liquid fertilizer with notation (s) consisting of 4 levels, namely: U0 = without the beef liquid organic fertilizer for cow Urine (control) U1 = 250 ml/l water U2 = 500 ml/l water U3 = 750 ml/L water II. Various doses of waste cabbage pupuk compost with notation (K) consisting of 3 levels, namely: K0 = no waste compost fertilizer (control) K1 = waste compost fertilizer Cabbage 1 kg/plot K2 = waste compost fertilizer Cabbage 2 kg/plot. Parameters that are in the die in this study are: high crop (cm), number of leaves (strands), length of cob (cm), gross weight of cob (GR) Net weight of Cob (GR), net weight of cob per Plot (GR).

The results of the study were obtained from this research, namely: 1). liquid organic fertilizer treatment of cow urine is real effect on the plant height, length of cob, gross cob weight, net cob weight, and heavy cob NET per plot, but the effect is not To the number of sweet corn plant leaves. The higher the concentration of cow urine up to 750 ml/L of water then the growth and production of sweet corn plants is also getting better. 2). The compost treatment is real influential cabbage to plant height, long cob, gross cob weight, heavy net cob, and heavy cob NET per plot, but the effect is not real to the number of sweet corn plant leaves. The higher the compost dose of waste cabbage up to 2 kg/m2 then the growth and production of sweet corn plants is also getting better 3). Interaction treatment of beef urine liquid organic fertilizer for cow Urine the compost wastes influence is not real against all the observed parameters.
