Abstract


ABSTRAK. Usahatani hortikultura khususnya sayuran sangat memerlukan kelembaban optimum agar ketersediaan air sesuai kebutuhan sayuran. Dalam budidaya tersebut diperlukan air irigasi untuk mempertahankan lengas tanah juga unsure hara untuk kelangsungan hidup tanaman dan perolehan hasil. Penelitian ini dilaksanakan di Stasiun Percobaan Tanggul (Desa Tawar), Kabupaten Hulu Sungai Selatan Propinsi Kalimantan Selatan pada musim kering 2007. Penelitian ini bertujuan untuk mengetahui akurasi pemupukan dan penggunaan air melalui sistem fertigasi dalam mengembangan tanaman cabai pada lahan kering lebak. Dosis pemupukan ditentukan oleh nilai Konduktivitas Elektrik (KE) dan derajat pH yang dirancang secara otomatis pada setiap fase pertumbuhan tanaman cabai. Penelitian ini menggunakan Rancangan Acak Kelompok dengan perlakuan dosis pemupukan NPK yang diulang sebanyak 3 kali. Peubah yang diamati adalah: keseragaman distribusi tetesan, pertumbuhan tanaman (tinggi, jumlah cabang, dan diameter kelopak) dan hasil. Hasil penelitian menunjukkan bahwa keseragaman distribusi tetesan bernilai >90%. Distribusi jatuh bukaan pada 3 pada 7.08 l h-1 dan Kl 1.19 mS cm-2 menunjukkan pertumbuhan vegetatif dan generative terbaik dengan meningkatkan tinggi 22.17 cm, bobot per tanaman 8.82 kg dan hasil sebesar 7.05 t ha-1.


Utilization of Machine Fertigation Type APH-03 for Chili in Fresh Water Swamp Land

ABSTRACT. Horticulture farming system especially vegetables need optimum soil moisture to full fill its water requirement. Maintaining its water content and nutrient for growing need irrigation system. Application of fertilizer and water in same time that named fertigation system is one of technology that introduced. The research was conducted at experimental station of Tanggul (Tawar village), Hulu Sungai Selatan Regency, South Kalimantan Province at dry season 2007. The object of research was to study the accuracy of fertilizer and water utilization through fertigation system for developing chili crop in dry season at fresh water swamp land. Fertilizer dosage was determine by Electrical Conductivity (EC) value and pH degree and automatically arranged with growing step of chili. Experimental design was randomized complete block design with three replication. The treatment was dosage NPK fertilizer. Parameter that observed was the distribution uniformity (DU), crop growth (height, number of branch and crown diameter) and yield. The result of research showed that distribution uniformity with value >90%. Drop distribution of aperture 3 as 7.08 l h-1 and EC 1.19 mS cm-2 showed better vegetative and generative growth with increase of height 22.17 cm, weight per bed as 8.82 kg and yield as 7.05 t ha-1.
