The Effect of Nano Technology Liquid Organic Fertilizer on The Growth of Red Spinach (Amaranthus tricolor L.) Cultivated Hydroponic

Hydroponic cultivation with a wick system is one of the techniques used to increase production red spinach (Amaranthus tricolor L.). One weaknesses hydroponics appearance nutrient deposition. To reduce deposition in system, it necessary apply nanotechnology break down particles growth media and nutrients so that become smaller are absorbed by plants more easily. Reduces precipitation system. This research was conducted using RAL method (completely randomized design) which consisted 6 treatments 4 replications namely Control (Well Water + 100% AB Mix), P1 (Nano Technology P2 25% POC+75% P3 (nano technology water+50% POC+50% P4 water+75% POC+25% P5 water+100% POC). The data obtained were analyzed variance (ANOVA) followed DMRT test at 5% level. results this study use liquid organic fertilizer nano had an effect on plants, seen highest plant height 37.20 cm average number leaves. P4. 28 leaves, leaf surface area 19.95 cm2 P3, wet weight 2.85 g control, dry P1. 0.67g.
