Pengaruh Lebar Bedengan dan Jarak Tanam Terhadap Pertumbuhan dan Hasil Benih Kentang (Solanum tuberosum L.) Generasi Dua (G2) Varietas Granola

he experiment was conducted in Experiment Station of Indonesia Institute for VegetableResearch (IIVR) Cikole Village, Lembang Subdistrict, West Bandung District, in October2015 to January 2016. The aim of this experiment was to find out the highest result ongrowth and yield of seed potato (Solanum tuberosum L.) Second Generation (G2) Granolavariety.The method experiment was used experimental method. It arranged in randomizedblock design (RBD) factorial, with four replications. There were two factors i.e: L= Bedwide and J= Plant spacing, with each - each consisting of three levels: l1 (80 cm), l2 (90 cm),l3 (100 cm) and j1 (10 cm), j2 ( 15 cm), j3 (20 cm). The results showed that there wereinteraction between bed wide and plant spacing on canopy diameter in 63 day after planting(dap), but its were not interaction on plant height, number of tubers per plant, tuber weight per plant and weight of tuber per plot. The highest canopy diameter of 26.75 cm was achieved by treatment l2j2 (90 cm x 15 cm).Key words :Solanum tuberosum; bed wide; plant spacing; growth; granola variet
