Response growth and yield some varieties of corn (Zea mays L.) to
organic fertilizer. The purpose of the experimental was to evaluate
response of varieties to organic fertilizer. Experimental was conducted
using by Randomize Block Design with two treatments consist of hybrid
varieties (P 12, BISI 2, NK 22, DK 3, JAYA 1) and organic fertilizer
(common fertilizer, ABG fertilizer), three replications was used to the
treatments. Data were analyzed using ANOVA and continued using HSD. The
results showed that varieties were significantly to all parameter accept
height of plant at 4 weeks planted. Organic fertilizer were
significantly to height of plant (at 4 weeks planted, at 5 weeks
planted, at 6 weeks planted, at 7 weeks planted) number of leaves (at 4
weeks planted, at 5 weeks planted, at 6 weeks planted), number of
leaves above the ear, male flowering dates, female flowering dates, age
of harvesting, seed fill rate, number of kernel per ear, weight 100 of
seeds and yield of plot. The combination between varieties and organic
fertilizer were significantly to seed fill rate and yield per plot.
Respons pertumbuhan dan produksi beberapa varietas jagung
(Zea mays L.) terhadap pemberian pupuk organik. Tujuan dari penelitian
ini adalah untuk mengetahui respons varietas terhadap pupuk
organik.penelitian ini menggunakan Rancangan Acak Kelompok dengan dua
faktor perlakuan yaitu varietas (P 12, BISI 2, NK 22, DK 3, JAYA 1) dan
pupuk organik (pupuk biasa, pupuk ABG), perlakuan diulang tiga kali.
Data yang diperoleh dianalisis dengan menggunakan ANOVA dan dilanjutkan
dengan Uji Beda Nyata Jujur (BNJ). Hasil analisis data menunjukkan bahwa
varietas berbeda nyata terhadap semua parameter kecuali tinggi tanaman 4
mst. Pupuk organik berbeda nyata terhadap tinggi tanaman 4 mst, 5 mst, 6
mst dan 7 mst, jumlah daun 4 mst, 5 mst dan 6 mst, jumlah daun di atas
tongkol, umur berbunga jantan, umur berbunga betina, umur panen, laju
pengisian biji, jumlah biji per tongkol, bobot 100 biji dan produksi per
plot. Interaksi antara varietas dan pupuk organik berpengaruh nyata
terhadap parameter tinggi tanaman 6 mst dan 7 mst, jumlah daun 5 dan 6
mst, laju pengisian biji dan produksi per plot
