Pengaruh Pemberian Kompos Batang Pisang dan Pupuk Organik Cair Ampas Tahu Terhadap Pertumbuhan dan Produksi Tanaman Bawang Merah (Allium ascalonicum L.)

Abstract

Research on shallot plants with a compost of banana stems and POC tofu waste is carried out on Hidayah 1 street, Mabar Hilir Sub-District, Medan Deli District, from April to June 2019. This study aims to determine the effect of banana stem compost and tofu liquid organic fertilizer on the growth and the production of Shallot (Allium ascalonicum L.) plants. This research uses a factorial randomized block design (RBD) consisting of 4 levels of compost banana stems: KO = cow manure, K1 = compost of banana stems 5 tons / ha (0.5 kg / m2)), K2 = compost of banana stem 10 tons / ha (1 kg / m2), K3 = compost of banana stem 15 tons / ha (1.5 kg / m2) and POC of 4 levels tofu waste: PO = control (urea 70 kg, za 150 kg, kcl 84 kg). The parameters observed are plant height, number of leaves, number of tubers, tuber diameter, plant tuber fresh weight per sample, plant tuber dry weight per sample, plant fresh weight per plot, plant tuber dry weight per plot. The results show that the use of banana stem compost and POC tofu waste does not significantly affect all the observation parameters, but the real and very significant effect is the use of cow manure on the number of leaf parameters.
