Pengguna Pupuk NPK Mutiara pada Metode Tanam Vertikultural Tanaman Bawang Merah ( Allium ascalonicum )

Abstract

Occurence of NPK Mutiara Fertilizer in Verticulture Planting System of Shallots (Allium ascalonicum). Shallots are one of main commodities in Indonesia. Shallots are usually cultivated in a wide range area. Verticulture method is a way to intensify a narrow cultivated area. Shallots cultivation were occured in a ram house in Universitas Medan Area Jl. Kolam No. 1 Medan. Cultivation has been conducted by using top soil as media in ram house with solubled NPK fertilizer into two litres of water. Yields of shallots were occured on B0 (control) was 1,44 g, B1 (50 g/pipe) was 1,03 g, B2 (75 g/pipe) was 0 g, B3 (100 g/pipe) was 0 g and B4 (125 g/pipa) was 0 g. Wet mass of shallots on B0 was 5,16 g, B1 was 3,54 g, B2 was 2,82 g, B3 was 1,17 g dan B4 was 1,37 g. Bulb mass and wet plant mass were indifferent to all treatments. Leaves number on B0 treatment was indifferent to other treatments. Heights on B0 treatment were absolutely different to all treatments except B1. High concentration of fertilization caused the plants dried and died. Further experiments with treatments of NPK fertilizer below 50 g/pipe was advised to the next experiments.
