PERENDAMAN DENGAN MENGGUNAKAN NOVELGRO ALPHAPADAPERKECAMBAHAN BIJI KOPI ROBUSTA (Coffea canephora)
Coffee plant during this export opportunity that is promising because in addition to meet the domestic coffee plant is also able to increase the country's foreign exchange through exports to countries of Europe and America. Robusta coffee is the coffee plant that is very important in the tropics, particularly in Asia and Africa. This research purposes to determine the concentration of PGR Novelgro Alpha optimal set of parameters when the emergence of shoots (days after sowing) and seed germination percentage of Robusta (Coffea canephora) . Research conducted at the Laboratory of Agronomy Lost Shadow s Polytechnic State Agricultural Samarinda. This research held for approximately tw o months from September to October 2015. The study is structured in four treatments (n). w here and every treatment has 25 seeds, the germination observations consisting of n0 Without PGR Novelgro Alpha., n1 concentration of PGR Novelgro Alpha is 0.7 ml / L of w ater., n2 concentration of PGR Novelgro Alpha is 1 ml / L of w ater, and n3 concentration of PGR Novelgro Alpha 1.7 ml / L water. Based on observations when the emergence of shoots in Table 1 indicate that the carrying n0 (w ithout soaking PGR Novelgro Alpha), n1 (immersion concentration of PGR Novelgro Alpha 0.7 ml / L of w ater), n2 (immersion concentration of PGR Novelgro Alpha 1 ml / L of w ater) , n3 (1.7 ml immersion concentration of PGR Novelgro Alpha / L of w ater) in a row is 20 days after sowing, 19 days after sowing, 18 days after sowing and 17 days after sowing and germination percentages Based on the calculation results in Table 2 show that germination percentage based treatment concentration of PGR Novelgro Alpha are respectively 56% (n0), 68% (n1), 76% (n2) and 88% (n3).
