Abstract

[ENGLISH]

The experiment was conducted in the Field Research, in Kumendung village, Muncar, Banyuwangi from November 2012 until February 2013. The objectives of the study was to evaluate the effect of NPK fertilizer in some accession of maize on it’s growth and production. It’s also evaluate the protein content of the accession under different fertilizer treatment. The experiment was set up as a split plot design with three replications. Main plot were NPK aplication rates (200, 300, 400 kg NPK ha-1) and the sub-plots were accesion number ( V1 = Srikandi Kuning x Manado Merah ; V2 = Bisma x Srikandi Kuning ; V3 = Srikandi Kuning x Bisma ; and V4 = Bisma x Manado Merah). An split plot statistical analysis of varience (ANOVA) and Duncan Multiple Range Test (DMRT) at 5 % level of probability according to Hanafiah, (2005) was realized using the excel program. Growth and yield parameters recorded at different stages of crop growth and development. There were plant height, leaves number above the ear, leaves number under the ear, tassel emergence, silk emergence, physiologically ripe age, ear lenghth, ear weight, ear circumference, ear weight per plot, kernel weight, kernel weight per plot, 100-grain weight, and protein content. The result showed that no significant different affected by the defferent NPK application rates on these accession. Base on the character selection, the yielding of all accession were higher than Bisma variety. Content of the accession were 11,14 ; 10,25 ; 10,95 ; and 10,10 mg g-1 for V1, V2, V3, and V4, respectively.

Penelitian dilakukan di lahan Desa Kumendung Kecamatan Muncar Kabupaten Banyuwangi pada bulan November 2012 hingga Febuari 2013. Tujuan dari percobaan ini adalah untuk mengevaluasi pengaruh pupuk NPK terhadap pertumbuhan dan produksi beberapa Aksesi jagung, dan mengevaluasi kadar protein yang terkandung didalamnya. Percobaan menggunakan Rancangan Split Plot dengan tiga ulangan. Petak utama adalah Pupuk NPK (200, 300, 400 kg NPK ha-1) dan sub-plot adalah aksesi jagung (V1 = Srikandi Kuning x Manado Merah, V2 = Bisma x Srikandi Kuning, V3 = Srikandi Kuning x Bisma, dan V4 = Bisma x Manado Merah). Hasil percobaan dianalisis dengan menggunakan analisis varian (ANOVA) dan Duncan Multiple Range Test (DMRT) pada taraf α 5% (Hanafiah, 2005) dengan menggunakan program excel. Parameter pengamatan meliputi tinggi tanaman, jumlah daun atas dan dibawah tongkol jagung, umur berbunga jantan, umur berbungan betina, umur masak fisiologis, berat tongkol per petak (kg), berat pipilan per petak (kg), berat tongkol per tanaman (g), panjang tongkol isi (cm), lingkar tongkol (cm), berat 100 biji per tanaman (g), dan kandungan protein biji jagung (mg g-1). Hasil penelitian menunjukkan bahwa tidak ada perbedaan yang nyata antar perlakuan yang dicobakan pada parameter yang diamati. Perlakuan penambahan pupuk NPK tidak menunjukkan pengaruh yang nyata pada semua parameter. Berdasarkan pemilihan karakter, semua aksesi terpilih lebih tinggi dibanding varietas Bisma. Kandungan protein rata-rata aksesi yang diuji yaitu 11,14 ; 10,25 ; 10,95 ; dan 10,10 mg g-1 masing-masing untuk V1, V2, V3, dan V4.
