Abstract: | Respon Pemberian Biochar Sekam Padi Dan Pupuk Kalium Fosfat Terhadap Pertumbuhan Dan Produksi Tanaman Kedelai (Glycine max (L.) Merril). Skripsi ini bawah bimbingan Bapak Ir. Gusmeizal, MP selaku ketua pembimbing dan Ibu Dr. Ir. Sumihar Hutapea, MS selaku anggota pembimbing. Penelitian ini dilaksanakan di lahan percobaan Fakultas Pertanian Universitas Medan Area yang berlokasi di Jalan PBSI No. 1 Medan Estate, Kecamatan Percut Sei Tuan dengan ketinggian tempat sekitar 22 m di atas permukaan laut (dpl), sejak September hingga Januari 2021. Penelitian ini dilakukan dengan menggunakan Rancangan Acak Kelompok (RAK) Faktorial yang terdiri dari 2 faktor perlakuan yaitu: 1). Pemberian Biochar Sekam Padi (notasi B) dengan 4 taraf perlakuan, yakni: B0= Tanpa biochar sekam padi; B1= Pemberian biochar sekam padi pada dosis 10 ton/ha; B2= Pemberian biochar sekam padi pada dosis 20 ton/ha; B3= Pemberian biochar sekam padi pada dosis 30 ton/ha. 2). Pemberian Pupuk Kalium Fosfat (notasi P) dengan 4 taraf perlakuan, yakni: P0= Tanpa pupuk Kalium Fosfat; P1= Pemberian pupuk Kalium Fosfat pada konsentrasi 0,3 %; P2= Pemberian pupuk Kalium Fosfat pada konsentrasi 0,6 %; P3= Pemberian pupuk Kalium Fosfat pada konsentrasi 0,9 %. Parameter yang diamati dalam penelitian ini adalah tinggi tanaman, jumlah daun, jumlah cabang, hari berbunga, panjang akar, berat akar segar, berat akar kering, biomassa tanaman, jumlah polong, jumlah biji, berat biji, dan berat 100 biji. Hasil yang diperoleh dalam penelitian ini, yakni: 1). Pemberian biochar sekam padi berpengaruh sangat nyata pada parameter tinggi tanaman umur, jumlah daun, jumlah cabang, dan berat biji, berpengaruh nyata pada parameter, panjang akar, biomassa tanaman, berat akar segar, berat akar kering, dan berpengauh tidak nyata pada parameter hari berbunga, jumlah polong, jumlah biji, dan berat 100 biji. Perlakuan pemberian biochar sekam padi pada dosis 30 ton/ha merupakan hasil yang terbaik. 2). Pemberian pupuk kalium fosfat berpengaruh sangat nyata pada parameter tinggi tanaman, jumlah daun, jumlah cabang, jumlah polong, jumlah biji, dan berat biji, berpengaruh nyata pada parameter biomassa tanaman, dan berat 100 biji, dan berpengaruh tidak nyata pada parameter hari berbunga, panjang akar, berat akar segar, dan berat akar kering. Perlakuan pemberian pupuk kalium fosfat pada konsentrasi 0,9 % merupakan hasil yang terbaik. 3). Interaksi pemberian biochar sekam padi dan pupuk kalium fosfat berpengaruh tidak nyata pada seluruh parameter. Response of Rice Husk Biochar and Potassium Phosphate Fertilizer on Growth and Production of Soybean (Glycine max (L.) Merril). This thesis under the guidance of Mr. Ir. Gusmeizal, MP as the head of the supervisor and Mrs. Dr. Ir. Sumihar Hutapea, MS as the supervising member. This research was conducted in the experimental field of the Faculty of Agriculture, University of Medan Area, which is located at Jalan PBSI No. 1 Medan Estate, Percut Sei Tuan Subdistrict with an altitude of about ± 22 m above sea level (asl), from September to January 2021. This research was conducted using a Factorial Randomized Block Design (RAK) consisting of 2 treatment factors, namely: 1 ). Provision of Rice Husk Biochar (notation B) with 4 levels of treatment, namely: B0 = No rice husk biochar; B1= Rice husk biochar at a dose of 10 tons/ha; B2= Rice husk biochar at a dose of 20 tons/ha; B3= Rice husk biochar at a dose of 30 tons/ha. 2). Provision of Potassium Phosphate Fertilizer (P notation) with 4 treatment levels, namely: P0 = No Potassium Phosphate fertilizer; P1= Potassium phosphate fertilizer application at a concentration of 0.3%; P2= Potassium phosphate fertilizer application at a concentration of 0.6%; P3= Potassium phosphate fertilizer application at a concentration of 0.9%. The parameters observed in this study were plant height, number of leaves, number of branches, flowering days, root length, fresh root weight, dry root weight, plant biomass, number of pods, number of seeds, seed weight, and weight of 100 seeds. in this study, namely: 1). The application of rice husk biochar had a very significant effect on the parameters of plant height, age, number of leaves, number of branches, and seed weight, had a significant effect on parameters, root length, plant biomass, fresh root weight, dry root weight, and had no significant effect on flowering day parameters. , number of pods, number of seeds, and weight of 100 seeds. The treatment of rice husk biochar at a dose of 30 tons/ha was the best result. 2). The application of potassium phosphate fertilizer had a very significant effect on the parameters of plant height, number of leaves, number of branches, number of pods, number of seeds, and weight of seeds, significantly affected parameters of plant biomass, and weight of 100 seeds, and had no significant effect on parameters of flowering day, length roots, fresh root weight, and dry root weight. The treatment of potassium phosphate fertilizer at a concentration of 0.9% was the best result. 3). The interaction of rice husk biochar and potassium phosphate fertilizer had no significant effect on all parameters. |
