The Effect Of Nano Technology Liquid Organic Fertilizer On The Growth Of Spinach (Amaranthus hybridus l.) Cultivated Hydroponically

Hydroponic cultivation using a wick system is one of the techniques used to increase production spinach (Amaranthus hybridus L.). One disadvantages hydroponics occurrence nutrient deposition, reduce deposition in apply nanotechnology break down particles planting medium and nutrients used, that become smaller more easily absorbed by plants, precipitation system. This research was conducted RAL method (Completely Randomized Design) which consisted 6 treatments 4 replications namely Control (Well water + AB Mix), P1 (Nano technology 100% P2 (nano 25% POC+75% P3 water+50% POC+50% P4 water+75% POC+25% P5 water+100% POC). The data obtained were analyzed means variance (ANOVA) followed DMRT test at 5% level. results this study are there an effect use nano liquid organic fertilizer on growth can be seen highest plant with 29.975 cm, number leaves 34 leaves, leaf area control 13,71 cm2, wet weight 17 gr, dry 1.3 gr. has influence green cultivated hydroponically.
