UJI KEMIRINGAN TALANG TERHADAP PERTUMBUHAN DAN HASIL TANAMAN CAISIM (Brassica juncea L.) HIDROPONIK DENGAN SISTEM Nutrient Film Technique (NFT)
Abstract
The research design used is experimental method using a randomized block design (RAK) with 4 treatments and 6 replications, each replication consisted of 13 plants, the number of plants examined as many as 312 plants. The number of plants observed in experimental unit that is 10 plants sample. The treatments studied were P1 = 1%, P2 = 3%, 5% P3, P4 = 7%. The parameters observed were plant height (cm), number of leaves (leaf), fresh weight of plants (g), weight wet above (g), weight wet under (g), leaf area (cm2) and plant dry weight (g ). Based on the results of the study concluded that, the slope of the gutter hydroponics good influence on the growth and yield of caisim (Brassica juncea L.) in hydroponic systems Nutrient Film Technique (NFT). Hydroponics gutters slope in treatment P4 (7%) resulted in the growth and yield better caisim, ie an average plant height of 35.49 cm at age 21 HST, as wide as 3522.62 cm2 leaf area, plant fresh weight average amounting to 75.62 g wet weight above average crop of 66.63 g and the weight of the wet below the average of 8.99 g.
