PENGARUH KEPEKATAN NUTRISI DAN BERBAGAI MEDIA TANAM PADA PERTUMBUHAN SERTA PRODUKSI BAWANG MERAH (Allium ascalonicum L) DENGAN HIDROPONIK NFT

Abstract

ABSTRACT
 The purpose of this study was to investigate the interaction of the application of AB Mix nutrition and growing media on the growth and production of Shallots (Allium ascalonicum L.) on NFT hydroponics. This study uses a ]Compound Plot Design in the form of a Completely Randomized Design consisting of the main plot, namely the nutrient concentration of AB Mix (N) and subplots of planting media (M). Nutrition AB Mix consists of 4 treatment levels, 600, 1200, 1800, 2400 ppm / l water and various planting media treatments consisting of 3 levels, namely husk, cocopeat, and sawdust charcoal media. Each experimental unit consisted of 4 plants and 2 plants used as samples. The parameters observed were as follows: plant height, harvest age, number of tubers, wet tuber weight, dry tuber weight, tuber weight per tuber, tuber weight loss. The observations of each treatment were statistically analyzed and continued with further tests of Honest Significant Difference at the 5% level. The interaction of the application of AB Mix nutrition and planting media had a real effect on all parameters, with the best AB Mix 1800 ppm and cocopeat growing media. The effect of AB Mix main plot has significantly affected all parameters observed with the best treatment of AB Mix 1800 ppm nutrition. The effect of subplot planting media significantly affected all parameters of observation with the best treatment of cocopeat growing media

The effect of planting media and seed soaking on the growth of true shallot (Allium ascalonicum L.) seeds

“…Cocopeat has a high porosity and aeration level. Aeration in the soil means that nutrient absorption will be efficient (Simbolon et al, 2018). Zeolite can automatically regulate the pH balance of the media due to the unique acidity-wetness properties of zeolite so it is very suitable for use as a planting media component (Mance et al, 2016).…”

Kajian Sistem Hidroponik Menggunakan Ultrasonic Atomizer Untuk Pembibitan TSS (True Shallot Seed) Bawang Merah

“…Gambar 4 menunjukkan letak penanaman benih dalam wadah semai dan pemberian nutrisi dengan sistem aeroponik. Mengacu kepada kajian bahwa penggunaan nutrisi AB Mix pada hidroponik NFT bawang merah hingga konsentrasi 1.800 ppm dapat menghasilkan pertumbuhan yang optimal (Simbolon et al, 2020). Penyemaian dilakukan selama 7 minggu dengan dengan pemberian nutrisi secara bertahap pada masa pembibitan yaitu rentang 135-1,048 ppm.…”

Pengaruh Konsentrasi Pemberian Pupuk Organik Cair Kipahit Terhadap Pertumbuhan Dan Hasil Tanaman Bawang Merah Secara Hidroponik

“…Menunjukkan perbedaan nyata pada perlakuan pemberian pupuk organik cair kipahit. Pada beberapa kali pengamatan perlakuan P6 (100%) menunjukkan jumlah rataan daun terbanyak yaitu 2, 50, 5,50, 6,25, 7,50, 8,75, 9,50, 10,25, dan 9,00. Hasil jumlah rataan daun menunjukkan bahwa kepekatan nutrisi berpengaruh pada pertumbuhan tanaman (Simbolon, 2018). Perlakuan pupuk organik cair kipahit memberikan pengaruh dalam percepatan dan perbanyakan terbentuknya pucuk daun muda, perbaikan tumbuhnya daun dan pucuk yang kurang produktif, membantuk proses regenerasi pada tanaman lebih cepat, memperbaiki proses pendistribusian garam mineral dan asam amino, meningkatkan kualitas umbi yang dihasilkan, pertumbuhan tunas, akar serta batang lebih cepat (Lestari, 2016).…”
