Response Of Growth Mustard Plant Pakchoy (Brassica Chinensis L.) The Composition Of Plant Medium And Dosage Of Npk By Verticulture



Respons of Growth Mustard Plant Pakchoy (Brassica chinensis L.) to Composition of Plant Medium and Dosage of NPK by Verticulture. The community consumption needs for vegetables are increasing, but mustard pakchoy production is still lacking, so research is needed on various aspects of cultivation techniques including fertilization. The study aimed to obtain the composition of plant medium and dosage of NPK by verticulture. This research was conducted at Deli Serdang in Agustus to September of 2017. Split Plot Design with 3 replicates. The composition of plant medium as the main plot consisted of M1 (charcoal husk: compost: soil), M2 (compost: coconut fiber: soil), M3 (coconut fiber: charcoal husk: soil). The dosage of NPK as subplot consisted N1 (1.5 g-plant), N2 (3 g-plant). N3 (4.5 g-plant). The results indicated that the composition of plant medium (charcoal husk: compost: soil) significantly affected on leaf chlorophyll, leaf area, fresh weight of plant and dry weight of the plant. The dosage of NPK (4.5 g-plant) significantly affected on leaf area, fresh weight of plant and harvest index. The interaction between the composition of plant medium with dosage NPK not significantly to all parameters.
