PEMBERIAN PUPUK AB MIX PADA TANAMAN PAKCOY PUTIH (Brassica rapa L.) DENGAN SISTEM HIDROPONIK RAKIT APUNG

Abstract

This research aims to obtain the proper nutrient concentration and the best nutrient concentration and increase the growth and yield of pakcoy through the floating hydroponic system. The research was conducted in the Experimental Farm of the Faculty of Agriculture, University of Riau from October to November 2019. The research used a non-factorial completely randomized design (CRD), consisting of 5 treatments and 4 replications. The given treatment was the nutrient concentration of AB Mix consisting of 5 levels: AB Mix 1000 ppm, AB Mix 1200 ppm, AB Mix 1400 ppm, AB Mix 1600 ppm, and AB Mix 1800 ppm. The parameters observed were plant height, leaf number, leaf area, root volume, plant fresh weight, and worthy weight consumption. The result showed that all the given treatments did not have significant towards all parameters. The concentration of 1000 ppm is the best concentration of some else, because more efficient, economic and saves the solution uses of nutrien in concentration. Based on the results of a study that has been conducted, to gain growth and the results of white pakcoy plant are both hydroponic can usea concentration of AB Mix 1000 ppm.

PERBANDINGAN PERTUMBUHAN TANAMAN SELADA MERAH (Lactuca sativa var. crispa) MENGGUNAKAN TEKNIK HIDROPONIK SISTEM DFT (DEEP FLOW TECHNIQUE) YANG DIBERI NUTRISI AB MIX DAN PUPUK ORGANIK CAIR DAUN KELOR (Moringa oleifera)

“…crispa) dengan menggunakan 2 media tanam yaitu nutrisi Ab Mix dan Pupuk Organik Cair Daun Kelor relatif memiliki pertumbuhan yang berbeda, sedangkan hasil rata-rata parameter dari tinggi tanaman, jumlah helai daun, lebar daun, bobot brangkasan basah dan morfologi daun memiliki perbedaan antara pemberian Nutrisi Ab Mix dan Pupuk Organik Cair Daun Kelor, berarti nilai rata-rata yang didapatkan yaitu signifikan. Hal ini berkaitan dengan pendapat Syah et al, (2021) Ab Mix merupakan nutrisi hidroponik yang terdiri dari stok A dan Stok B. larutan stok A berisi unsur hara makro yaitu Nitrogen (N), Fosfor (P), Kalium (K), Kalsium (Ca), Magnesium (Mg), dan Sulfur (F), sedangkan stok B berisi unsur hara mikro yaitu Besi (Fe), Mangan (Mn), Boron (B), Tembaga (Cu), Zeng (Zn) dan Molibdenum (Mo). Menurut Tomia et al, (2021), senyawa yang terkandung didalam daun kelor seperti Fosor, Magnesium, Kalsium, Zat besi dan sulfur, sehingga daun kelor dapat dimanfaatkan untuk pembuatan pupuk organik cair, karena dapat meningkatkan efesiensi terhadap tanaman.…”
