Abstract

This study aims to determine the effect of nft aquaponic altitude and the type of growing media on the growth and yield of ground water spinach (Ipomea reptans Poir). This research was carried out at Dokagu UIR Housing Block b No. 2, Air cold Village, Bukit Raya District, Pekanbaru City, Riau Province. It was carried out for 2 months, August – September 2022. This study used a Split Plot Design (RPT) in Factorial RAL. The main plot was the position of the aquaponic elevation (T) which consisted of 3 treatment levels, namely: height 60, 100, and 140 cm . Subplots were a type of planting medium (M) which consisted of 2 treatment levels, namely: rockwool and kale root, 6 treatment combinations were obtained with 3 replications, so there were 18 experimental units. Parameters observed were plant height, number of leaves, economic wet weight, dry weight, root volume, and root canopy ratio. The data were analyzed statistically and continued with the honest significant difference test (BNJ) at the 5% level. The results showed the effect of the main plot of aquaponic elevation position and the type of planting media significantly on the parameters of plant height, number of leaves, root volume, economic wet weight and plant dry weight. All parameters of ground kale plants observed in this study obtained the best results at an aquaponic height of 140 cm and rockwool growing media. Aquaponic altitude position has a real influence on all plant parameters. The best aquaponic elevation position is at a height of 140 cm. The treatment of growing media had a significant effect on all parameters observed and rockwool growing media was the best and had a significant effect on all parameters.
