Optimasi Produksi Empat Varietas Jagung Hibrida Di Kertosono, Kabupaten Nganjuk

Abstract

Maize hybridization system would help Indonesia to become a maize exporter. But the development of maize hybrids in Indonesia is seemed too slow, this impacting in national maize production, which was only 13 million ton per year in 2003. In 2009, the maize hybrid has been planted in about 54% of maize yields. Fertilizing maize is on the most essential and critical parts about growing maize. The objective of the study was to obtain the maximum dosage of composed fertilizer for the highest productivity among four hybrids maize variety in dependingsoil type. The result showed that the prospecting hybrid variety of BI-1 has a maximum production yield of 7.7 ton/ha at the level of fertilizer 1,200 kg/ha and it was only 6.3 ton per ha at zero level fertilizer. Amount of 7.4 ton/ha was achieved by BI-3 maize hybrid at the level of 1,200 kg/ha fertilizer, where those only 5.8 ton/ha at the zero level of fertilizer. The highest productivity was archived by BI-4 where it was 7.1 ton/ha at zero level fertilizer and the highest production yield of 9.2 ton/ha at 900kg/ha of fertilizer, but it was decrease at the level of 1,200 kg/ha fertilizer. Maize variety of DK979 achieved highest productivity of 8.6 ton/ha at 1,200 kg/ha fertilizer and 5.8 ton/ha at zero level fertilizer.

Karakter agronomi beberapa jagung hibrida Padjadjaran dan hubungannya dengan hasil di dataran medium

“…Banziger et al (2004) mengemukakan bahwa varietas unggul baru jagung hibrida diperoleh melalui program pemuliaan tanaman yang berkelanjutan. Upaya tersebut juga didukung oleh kebijakan Kementerian Pertanian 2014 dalam budidaya tanaman jagung dengan target penanaman jagung hibrida mencapai 75% (Sutardjo et al, 2012).…”

Efisiensi Ekonomi Usahatani Jagung Hibrida Di Pulau Madura

“…Penggunaan faktor produksi usahatani jagung hibrida di Pulau Madura seringkali tidak sesuai dengan anjuran sehingga berdampak terhadap biaya dan tingkat produksi yang dihasilkan. Dibuktikan dengan adanya selisih produksi antara usahatani jagung hibrida di Pulau Madura yakni 4,2 ton/ha dengan hasil produksi di Kabupaten Nganjuk yakni 7,1 -9,2 ton/ha (Sutradjo, 2014). Permasalahan lain dalam usahatani jagung hibrida di Pulau Madura adalah tingginya harga input produksi seperti benih yang mencapai harga Rp 75.000/kg dan harga pupuk yang mengalami kenaikan saat masuknya musim tanam.…”
