Pengaruh Beberapa Media Tanam terhadap Karakter Agronomis dan Kandungan Klorofil Microgreens Sawi (Brassica Juncea L.)

Abstract

The success of growing microgreens cannot be separated from the use of planting media, the planting media functions as a standing medium and provides nutrients and water that will be absorbed by the roots for the plants to grow. This research aims to analyze the effect of several planting media on the agronomic characteristics and chlorophyll content of mustard greens (Brassica juncea L.). This research was carried out in Bangun Sari Village, Tanjung Morawa District and the Laboratory of the Faculty of Agriculture, University of North Sumatra from May 2024 to June 2024. The research used a non-factorial Randomized Group Design (RAK) repeated six times with several planting media treatments consisting of rockwool, charcoal husk, cocopeat, and a mixture of husk charcoal: cocopeat (1:1). The results showed that the planting medium had a significant effect on increasing plant height and wet weight but had no significant effect on the number of leaves, chlorophyll a content, chlorophyll b content and total chlorophyll content. The planting media were husk charcoal, cocopeat, and a mixture of husk charcoal: cocopeat produced higher plant height and wet weight and showed significant differences compared to rockwool planting media.
