Pemberian Dosis POC Jakaba Terhadap Pertumbuhan dan Produksi Tanaman Pakcoy (Brassica rapa L.)
Application of Jakaba LOF Doses on Growth and Production of Turnip Greens (Brassica rapa L.)
Abstract
Tanaman pakcoy (Brassica rapa L.) termasuk salah satu jenis sayuran yang mudah untuk dibudidayakan dan berumur pendek. Tanaman pakcoy menjadi salah satu jenis sayuran yang banyak dikonsumsi oleh sebagian besar masyarakat. Penelitian ini bertujuan untuk menganalisis dosis pemberian POC jakaba yang tepat terhadap pertumbuhan dan produksi tanaman pakcoy. POC Jakaba merupakan pupuk cair hasil fermentasi yang berasal dari bahan anorganik kaya akan nutrisi dan mikroorganisme yang menguntungkan bagi tanaman. Penelitian dilaksanakan di lahan Politeknik Pertanian Negeri Payakumbuh pada bulan Mei sampai bulan Juni tahun 2023. Metode yang digunakan adalah desain eksperimen dengan Rancangan Acak Lengkap (RAL) yang dilakukan dengan 3 perlakuan yaitu pupuk anorganik NPK(16:16:16), 20 ml/L dan 40 ml/L POC jakaba dengan 6 ulangan serentak. Hasil penelitian menunjukkan bahwa pemberian dosis POC jakaba terhadap pertumbuhan dan produksi tanaman pakcoy memberikan hasil berbeda nyata pada variabel pengamatan panjang daun, tinggi tanaman dan bobot segar tanaman. Perlakuan terbaik ditunjukan pada dosis 40 ml/L = 13,62 cm, tinggi tanaman = 19,79 cm dan bobot segar tanaman = 129,73 gr. Hasil tidak berbeda nyata ditemukan pada variabel pengamatan jumlah daun, dan lebar daun.
Turnip greens (Brassica rapa L.) are a type of vegetable that is easy to grow and short-lived. Turnip greensplants are a type of vegetable that is widely consumed by most people. This study aims to analyze the correct dosage of Jakaba Liquid Organic Fertilizer (LOF) on the growth and production of turnip greensplants. Jakaba LOF is a fermented liquid fertilizer derived from inorganic materials rich in nutrients and microorganisms that are beneficial to plants. The research was conducted at the Payakumbuh State Agricultural Polytechnic land in May to June 2023. The method used was a Completely Randomized Design (CRD) with 3 treatments, namely NPK inorganic fertilizer (16:16:16), 20 ml/l and 40 ml/l of Jakaba LOF with 6 replications simultaneously. The results showed that the dosage of Jakaba Liquid Organic Fertilizer on the growth and production of turnip greensplants gave significantly different results on the observation variables of leaf length, plant height and plant fresh weight. The best treatment was shown at a dose of 40 ml/L = 13.62 cm, plant height = 19.79 cm and plant fresh weight = 129.73 g. The results were not significantly different in the observation variables of number of leaves, and leaf width.
