Respon Pemberian Pupuk Organik Cair Keong Mas dan Biochar Kendaga Biji Karet Terhadap Peningkatan Produksi Tanaman Padi Hitam (Oriza Sativa L.)

Abstract

Black rice plants have an effect on plant height, number of tillers, and dry weight of straw per clump, but do not affect flowering age, grain weight per bed, weight per 1000 grains of grain, weight of filled grain, and weight of non-contained grain. This research was conducted in February 2020 until completion in the experimental field of the Faculty of Agriculture, University of Medan, Jalan PBSI No.1Medan Estate, Percut Sei Tuan District, Dli Serdang Regency with an altitude of 22 meters above sea level and alluviall soil types, flat topography and soil pH. 5-7. The method used in this research was the factorial randomized block design (RAK) method which consisted of 2 treatment factors, namely: 1) The golden snail liquid organic fertilizer consisted of 4 treatment levels, namely: K0 = without liquid organic fertilizer. control); K1 = 1% mas snail liquid organic fertilizer (100 ml / liter); K2 = 2% mas snail liquid organic fertilizer (200 ml / liter); K3 = 3% mas snail liquid organic fertilizer (300 ml / liter) and 2) Kendaga rubber seed Biochar consists of 4 treatment levels, namely: B0 = Control (without treatment); B1 = Biochar kendaga rubber seeds at a dose of 5 tons / Ha (0.5 Kg / plot); B2 = Biochar kendaga rubber seeds with a dose of 10 tons / Ha (1 Kg / plot); B3 = Biochar kendaga rubber seeds at a dose of 15 tonnes / ha (1.5 kg / plot). Tanaman padi hitam berpengaruh terhadap tinggi tanaman, jumlah anakan, dan berat kering jerami per rumpun, namun tidak berpengaruh terhadap umur berbunga, bobot gabah per bedengan, bobot per 1000 butir gabah, bobot gabah berisi, dan bobot gabah tidak berisi. Penelitian ini dilaksanakan pada bulan Februari 2020 sampai dengan selesai di lahan percobaan Fakultas Pertanian Universitas Medan Area Jalan PBSI No.1Medan Estate, Kecamatan percut Sei Tuan Kabupaten Dli Serdang dengan ketinggian tempat 22 meter diatas permukaan laut dan jenis tanah aluviall,topografi datar dan pH tanah 5-7.Metode yang digunakan dalam penelitian ini adalah metode Rancangan Acak Kelompok (RAK) Faktorial yang terdiri dari 2 faktor Perlakuan yaitu: 1)Pupuk Organik Cair keong mas terdiri dari 4 Taraf Perlakuan yaitu: K0= tanpa pupuk organik cair keong mas (kontrol) ; K1 = pupuk organik cair keong mas 1 % (100 ml/liter) ; K2 = pupuk organik cair keong mas 2% (200 ml/liter); K3 = pupuk organik cair keong mas 3% (300 ml/liter) dan 2) Biochar kendaga biji karet terdiri dari 4 Taraf Perlakuan yaitu: B0= Kontrol (Tanpa Perlakuan); B1= Biochar kendaga biji karet dengan dosis 5 Ton/ Ha ( 0,5 Kg/ Plot) ;B2= Biochar kendaga biji karet dengan Dosis 10 Ton/ Ha (1 Kg/ Plot); B3 = Biochar kendaga biji karet dengan Dosis 15 Ton/Ha ( 1,5 Kg/Plot).
