Abstract

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

Abstract

Hydroponics is a method of agriculture in which earth is not used. Among the plants amenable to hydroponic cultivation is red lettuce. One disadvantage of hydroponic cultivation is the occurrence of nutrient deposition, particularly in the wick system, where the nutrient water does not move. A technique that can lessen the amount of nutrient deposition that occurs in hydroponic systems is required in light of the aforementioned issues. Nanotechnology is one of the technologies developed. The five treatments and four replications in this study were P1 = AB Mix 100 percent, P2 = AB Mix 75 percent + POC Nano 25 percent, P3 = AB Mix 50 percent + POC Nano 50 percent, P4 = AB Mix 25 percent + POC Nano 75 percent, and P5 = POC Nano 100 percent. ANOVA (Analysis of Variance) was used to analyze the data, and the Duncan's New Multiple Range Test (DMRT) test at level 5 followed. The effects of nanotechnology-enhanced liquid organic fertilizer on red lettuce growth, including height, leaf area, number of leaves, fresh weight, and dry weight, were examined. The highest average plant is at P3 with a plant height of 36.42 cm, the highest average number of leaves is at P3 as many as 11.25 strands, the widest average leaf is at P4 with an area of ​​40.25 cm2, the average weight The highest wet weight was P4 with a weight of 17.01 g, and the highest average dry weight was P2 with a weight of 1.32 g.
