Abstract

This research was carried out from February to April 2022, in the yard of Naikoten
Satu Output, Kupang City, with the aim of knowing the combination of the composition of
soil planting media, husk charcoal, and cow dung on the growth and yield of mustard plants.
This research was designed with a completely randomized design (CRD). The treatment
being tested was kobasi the composition of soil planting media material, husk charcoal, and
cow dung manure which consisted of 6 treatments. P0 = Soil (100%), P1 = Soil with rice
husk charcoal (2:1), P2 = Soil with cow manure (2:1), P3 = Soil with rice husk charcoal
(1:1), P4 = Soil with cow dung manure (1:1), P5 = Soil with husk charcoal and cow dung
manure (1:1:1). Each treatment was carried out in four (4) replications. Observational
variable data (height, number of mustard leaves, total plant fresh weight and net fresh
weight of mustard greens were analyzed using Variety Print Analysis, followed by Duncan
Multiple Range Test (DMRT) at 5% level. The results showed: 1). The combination
treatment of soil media composition, husk charcoal, and cow manure had a significant and
very significant effect on the height and number of leaves of mustard plants at observations
3 and 4 MSPT (1 WAP and 2 WAP), gross fresh weight, and net fresh weight, 2) . The
combination treatment of soil media composition, husk charcoal, and cow manure ratio 1: 1:
1 (P5) gave the best results on plant height, number of leaves, fresh gross weight, fresh net
weight, each of which was 28.70 cm for height. plants, 10.50 leaves for the number of
leaves, 39.00 grams for fresh gross weight and 35.08 grams for fresh net weight of mustard
greens.
