The Growth Of Lettuce (Lactuca sativa) Hydroponically In Simple Wick System On Various Types Of Nutrient Composition

The supply of hydroponic nutrients needs to consider economic, practical and resource saving aspects. It is necessary know the best composition type that can be used in a system. use liquid organic fertilizers (POC) as an alternative nutrients, especially wick system, has already begun including widely available such NPK + Gandasil utilizing chicken feather waste been made form fertilizer. This research expected provide overview potential for nutrient sources growing media by resources. study was started from June August 2020, using single randomized block design (RBD) consisting 5 (five) treatment levels, namely: K0 = AB mix (control) 50 ml / 10 L water, K10 g 5g 10L water. K11 1/2 dose Abmix ½ Gandasil, K12 4800ml POC feathers K13 results showed had no significant effect on plant height weeks 1,2,3 4, leaf length 1 2 number leaves 4. weeks. 3rd 4th week.The obtained at K0. (Abmix), which significantly different k10 k12 treatments, not all k11 13 treatments.At week also k0 treatments. real with other There utilization, because it able approach growth standard variables number.
