Utilization Of Various Fish Dung On The Growth And Production Of Lettuce (Lactuca Sativa L.) In The Aquaponic System



The growing population where is not followed by accretion of land and in increased and as well as the high over its role in taking function of farmland into land other uses, made of farmland are increasingly limited. Whereas the needs food and vegetableskept rising throughout. Hence aquaponic of providing an alternative farming in land limited by combining system aquatics and hydroponic in the environment symbiotic. This study aims to evaluate the effect of various types of fish dung on the growth and production of lettuce (Lactuca sativa L.) on the aquaponic system. This research conducted on Agriculture Faculty experimental land of University of Muhammadiyah Sumatera Utara. The research used Randomized Block Design (RBD) non factorial with a factor that be researched was dung of fishes of five of a kind fish, namely: K1: catfish dung of fishes, K2: tilapia dung of fishes, K3: gurame dung of fishes, K4: goldfish dung of fishes and K5: bawal dung of fishes. Parameter that measured covering: plant height, number of leaves, weight per plant. The result showed that dung of fishes had significant effect on plant height, number of leaves, and weight per plant. Thus, the various dung of fishes in aquaponic system had significant effect on the growth and yield of lettuce
