RESPON TANAMAN KACANG TANAH (Arachis hypogaea L.) TERHADAP PUPUK BOKASHI DAN NPK

Abstract

This study aims to determine the fertilization combination effect of Bokashi and NPK on growth and yield of peanut. The research was conducted on land Gading Kulon village,Dau Subdistrict, Malang District in July to September 2014. The study was conducted using a randomized block design (RAK), which consists of two factors: 1) Factor 1 Type Bokashi: B1 = Bokashi chicken manure and B2 = Bokashi husk, 2) factor 2 dose NPK: D0 = Without NPK, D1 = 50 kg / ha of NPK and D2 = 100 kg / ha NPK. There were six combinations of treatments, each treatment was repeated 4 times, so there were 24 experiments. The variables measured were plant height, leaf number, number of branches, biomass plants, pods, pods wet weight, dry weight of pods. Each plot experiment was observed 5 plants. The results showed that there were an interaction between Bokashi type and NPK fertilizer on the plant height age of 21 days, the number of leaves 14 days old, 14 days old branch number and weight of pods wet and dry peas weight. Separately, NPK fertilizer effect on plant height age of 21 days while Bokashi fertilizer effect on plant biomass. The best result of Peanut yield (pod wet, dry pods) is obtained at treatment Bokashi chicken manure with NPK 50 kg / ha (B1D1) and did not differ with Bokashi husk without NPK (B2D0) and Bokashi rice husk with NPK 100 kg / ha (B2D2 ).

Penelitian bertujuan untuk mengetahui pengaruh kombinasi pemupukan bokashi dan NPK terhadap pertumbuhan dan hasil kacang tanah. Penelitian dilaksanakan di lahan Desa Gading Kulon, Kecamatan Dau, Kabupaten Malang pada bulan Juli sampai bulan September 2014. Penelitian dilakukan dengan metode Rancangan Acak Kelompok (RAK) yang terdiri dari 2 faktor yaitu: 1) Faktor 1 Jenis Bokashi:B1 = Bokashi kotoran ayam dan B2 = Bokashi arang sekam, 2) Faktor 2 Dosis NPK: D0 = Tanpa NPK, D1 = 50 kg/ha NPK dan D2 = 100 kg/ha NPK. Jadi terdapat 6 kombinasi perlakuan, masing-masing perlakuan diulang 4 kali, sehingga terdapat 24 perlakuaan.Variabel yang diamati, tinggi tanaman, jumlah daun, jumlah cabang, biomassa tanaman, jumlah polong, bobot polong basah, bobot polong kering. Setiap petak percobaan diamati 5 tanaman. Hasil penelitian menunjukan bahwa terdapat interaksi antara jenis bokashi dan pupuk NPK terhadap tinggi tanaman umur 21 hari, jumlah daun umur 14 hari, jumlah cabang umur 14 hari, berat polong basah dan berat polong kering. Secara terpisah pupuk NPK berpengaruh terhadap tinggi tanaman umurn 21 hari sedangkan pupuk bokashi berpengaruh terhadap biomassa tanaman.Hasil kacang tanah (polong basah dan polong kering) terbaik diperoleh pada bokashi kotoran ayam dengan NPK 50 kg/ha (B1D1) dan tidak berbeda dengan bokashi arang sekam tanpa NPK (B2D0) maupun dengan NPK 100 kg/ha (B2D2).
