SUMMARY Gunedi Saufa Asri . Effect of Planting Distance and Concentration Organic Liquid Fertilizer Top G2 Against Plant Growth and Yield Rosella ( Hibiscus sabdariffa L. ) under the guidance of Biological Mardhiah as primary mentors and tutors Erida Nurahmi as members . This study aimed to determine the effect of spacing and concentration G2 TOP liquid organic fertilizer on growth and yield of Roselle , and apparent absence of interaction between the two factors. The research was conducted at the Experimental Station of the Faculty of Agriculture of Banda Aceh, which started from March 2011 to September 2011. Materials and tools used are the seeds rosella sabdariffa varieties , manure , polybag, hoes, rakes, yells, machetes, analytical scales, meter, signage, stationery and writing. This study uses a randomized complete block design ( RAK ) 3 x 3 factorial with 3 replications. There are two factors studied were spacing consists of 3 levels ie 60 cm x 60 cm , 80 cm x 80 cm , 100 cm x 100 cm and the concentration of liquid organic fertilizer TOP G2 consisting of 3 levels ie 2 ml / l of water , 4 ml / l of water , and 6 ml / l of water. Variables measured against the roselle plant include plant height ( cm ) , number of branches , number of petals, flower petals and wet weight ( g ) per plant . Spacing is very significant effect on the number of branches per plant life of 60 days after planting and the heavy wet petals , significantly affect the number of branches per plant life of 45 days after planting and no apparent effect on plant height at 15, 30 , 45 and 60 days after planting , the number of branches per plant life 15 and 30 days after planting , and the number of petals per plant ages 65 and 75 days after planting . At the treatment plant spacing , number of branches per plant best in treatment spacing of 60 cm x 60 cm and wet weight per plant rosella flower petals on the best treatment spacing of 80 cm x 80 cm. TOP liquid organic fertilizer G2 very significant effect on plant height at 30 , 45 and 60 days after planting , the number of branches at 15, 45 and 60 days after planting , the number of petals aged 65 and 75 days after planting , and flower petals wet weight per plant . Furthermore no significant effect on plant height age 15 HST and number of branches per plant at 30 days after planting . Concentration of liquid organic fertilizer TOP G2 gives growth and yield of roselle best in treatment 6 ml / L of water . There is a very real interaction between spacing treatments with liquid organic fertilizer concentration TOP G2 to the number of branches per plant at the age of 60 HST . Best combination of treatments are on treatment spacing of 100 cm x 100 cm with a liquid organic fertilizer concentration TOP G2 6 ml / L of water .
