Abstract

Penelitian ini bertujuan untuk mengetahui potensi hasil 5 varietas unggul kedelai yang dibudidayakan di lahan kering masam serta memberikan referensi bagi para petani tentang varietas unggul yang mampu berproduksi secara maksimal di lahan kering masam. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) non faktorial dengan menggunakan 5 benih kedelai varietas unggul yaitu Dega 1, Detap 1, Grobogan, Devon 1 dan Dena 1 Parameter yang diamati dalam penelitian ini antara lain: tinggi tanaman, umur berbunga, jumlah cabang produktif, umur panen, jumlah polong per tanaman , berat biji per tanaman, berat 100 biji, dan rata-rata potensi hasil. Hasil penelitian menunjukkan setiap varietas memiliki respon berbeda terhadap lingkungan sehingga pertumbuhan dan potensi hasil yang diperoleh juga berbeda. Pada penelitian ini V2 (Detap 1) memiliki produksi per hektar paling tinggi dibandingkan dengan 4 varietas lainnya. Potensi hasil dan daya adaptasi yang cukup baik di lahan kering masam ditunjukkan oleh V2 (Detap 1) indikator kemampuan potensi hasil dan daya adaptasi tersebut didasarkan atas tingkat produktivitas varietas tersebut.

Abstract

Provision of biochar as a to soil make better either directly or formulated beforehand with other materials such as with a combination of NPK fertilizers is expected to improve soil physical properties. This study aims to determine the effect of biochar application and NPK either single factor or interaction to changes in soil physical properties, as well as the growth and yield of potatoes. Research using randomized block design (RAK), consists of two factors, namely biochar and NPK. Factors biochar consists of four levels, namely; (1) B0 = Biochar doses of 0 tons ha-1, (2) B1 = Biochar dose of 15 ton ha-1, (3) B2 = Biochar dose of 30 tons ha-1, and (4) B3 = Biochar dose of 45 tons ha-1, while NPK consists of three levels, namely; (1) P0 = NPK doses of 0 kg ha-1, (2) P1 = NPK fertilizer dose of 400 kg ha-1, and (3) P2 = NPK fertilizer dose of 800 kg ha-1. Biochar and NPK fertilizers by the interaction of very significant effect on heavy volume, porosity, stability index aggregated, drainage pore fast, pore slow drainage and pore water available soil, plant height ages of 30 and 45 days after planting, the number of tubers per hill, tuber weight per clump, and weight of tuber per plot. The highest value of potato tuber weight per plot found in biochar dose of 30 tons ha-1 with NPK fertilizer dose of 400 kg ha-1 with a yield of potatoes to a maximum of 16.33 kg plot-1. Keywords: biochar, NPK, potato, soil physical properties
