Penelitian ini dilakukan di lahan percobaan Fakultas Pertanian Universitas Sumatera Utara yang berada ± 25 m dpl mulai Mei sampai Agustus 2015. Tujuan penelitian ini yaitu untuk mengetahui kemampuan pupuk hayati dan tepung cangkang telur dalam meningkatkan pertumbuhan dan produksi tanaman kedelai. Penelitian menggunakan Rancangan Acak Kelompok dengan 2 faktor perlakuan. Faktor pertama adalah pemberian pupuk hayati yaitu 0 ; 5 dan 10 g/kg benih dan faktor kedua tepung cangkang telur yaitu 0 ; 25 ; 50 dan 75 g/polibeg. Hasil penelitian menunjukkan bahwa pemberian pupuk hayati meningkatkan jumlah dan berat bintil akar efektif dan bobot biji kering per tanaman. Sedangkan perlakuan tepung cangkang telur nyata dalam meningkatkan jumlah dan bobot bintil akar efektif. Sedangkan interaksi antara pupuk hayati dan tepung cangkang telur cenderung meningkatkan jumlah dan berat bintil akar efektif dan bobot biji kering per tanaman.
This research was conducted at the experimental field of Faculty of Agriculture, University of Sumatera Utara located ± 25 m above sea level on May to August 2015. The objective of the research was to determine the ability of biological fertilizer and eggshell powder on growth and production of soybean. This research using Randomized Block Design with 2 factors. The first factor was application of biological fertilizer ie (0 ; 5 and 10 g/kg seeds ) and the second factors was eggshell powder ie (0 ; 25 ; 50 and 75 g/plant ). This research showed that application of eggshell powder increased the number and weight of effective nodule and dry seeds weight per plant. While the biological fertilizer treatment significantly increased the number and weight of effective nodule. The interaction among eggshell powder and biological fertilizer tended to increase number and weight of effective nodule and dry seeds weight per plant.
