Pengaruh Populasi Ikan Lele Dan Jenis Media Tanam Terhadap Pertumbuhan Dan Hasil Tanaman Bayam (Amaranthus Sp.) Pada Sistem Akuaponik

This study aims to the interaction between catfish populations and type of growing media on growth yield spinach (Amaranthus sp.) Cultivated by aquaponics system. research was conducted using an experimental method (experiment), from July August 2020 in area PUSKOPAD complex, Tanjungsari District, Sumedang Regency. at altitude 850 m above sea level. The design used Split Plot Design with basic RAK. Which consists 2 factors repetitions. first factor or mainplot is population (i) which 4 levels, namely: (i1) = 0 tails, (i2) 10 (i3) 20 (i4) 30 tails. second subplot planting medium (m) types, (m1) Rockwool, (m2) Oyster mushroom waste, (m3) husk charcoal, (m4) Pumice stone. Based results experiments regarding influence grown aquaponic That there treatment parameters observation plant height days after (DAS) DAS leaf number 35 DAS. use pumice best for cultivation system a sufficient provide nutrient needs needed plants.
