Abstract: Soybean is a protein material and essential commodity in Indonesia. National soybean production has decreased each year. The low production of soybean Indonesia one of them because there is maximal knowledge of farmers in the use of technologies that support sustainable agricultural productionIncreasing number of imported transgenic soybeans and high public awareness of healthy living, then powered back organic farming systems. The research objective which is to determine the response of growth and production of soybean on application of biochar and liquid organic fertilizer. The experiment was conducted in Namo Gajah Village District of Medan TuntunganOn Junetol August 2015, using a factorial randomized block design with two factors, biochar(0, 4, 8, 12t/ha)and liquid organic fertilizer (20, 40, 60 ml / l). Observed were plant height, stem diameter, total leaf area, crop growth rate,net assimilation rate, relative growth rate, age of flowering , age of harvesting, the number of pods per plant lists, the number of empty pods per plant, seeds per plant dry weight, dry weight of seeds per plots, the dry weight of 100 seeds. The results showed that application of biochar increased the number of total leaf area 3,4 and 6 WAP, net assimilation rate 3-4WAP, and dry weight of seeds per plots. liquid organic fertilizer increasing the number of effective stem diameter,total leaf area 4 and 6 WAP andassimilation rate 3-4 WAP.
Abstract (other language): Kedelai merupakan bahan protein nabati dan komoditas penting Indonesia. Produksi kedelai nasional mengalami penurunan setiap tahunnya.Rendahnya produksi kedelai Indonesia salah satunya dikarenakan belum maksimalnya pengetahuan petani dalam penggunaan teknologi produksi yang mendukung pertanian berkelanjutan. Serta semakin banyaknya kedelai impor transgenik dan tingginya kesadaran masyarakat untuk hidup sehat, maka diberdayakan kembali sistem pertanian organik Tujuan penelitian yakni untuk mengetahui respons pertumbuhan dan produksi kedelai terhadap pemberian biochar dan pupuk organik cair. Penelitian dilaksanakan di Medan Tuntungan Desa Namo Gajah pada Juni 2015 sampai Agustus 2015, menggunakan Rancangan Acak Kelompok Faktorial dengan dua faktor yaitu Biochar (0, 4, 8, 12t/ha) dan Pupuk Organik Cair (20, 40, 60 ml/l). Peubah yang diamati adalah tinggi tanaman, diameter batang, total luas laju pertumbuhan tanaman, laju asimilasi bersih, laju pertumbuhan relatif, umur berbunga, umur panen, jumlah cabang produktif, jumlah polong berisi per tanaman, jumlah polong hampa per tanaman, bobot kering biji per tanaman, bobot kering biji per plot, bobot 100 biji kering. Hasil penelitian menunjukkan bahwa pemberian biochar meningkatkan Total Luas Daun 3,4 dan 6 MST, Laju asimilasi bersih 3-4 MST, dan bobot kering biji per plot. Pemberian Pemberian pupuk organik cair meningkatkan jumlah diameter batang, Total Luas Daun 4 dan 6 MST, Laju asimilasi bersih 3-4 MST.
