TOLERANSI TANAMAN SAWI HIJAU (BRASSICA JUNCEA L.) TERHADAP CEKAMAN SALINITAS GARAM NACL
ABSTRACT: High levels of salt
in the soil may cause the disruption of plant growth, especially the crops.
Mustard greens (Brassica juncea L.) as the main vegetable commodity in West
Kalimantan, is grown on soil with normally salinity level. The purpose of this
research was to determine the growth response of mustard greens (B. juncea)
against the exposure to the NaCl. The research was carried out from August to
Oktober 2014. Research was carried out using the Completely Randomized Design
(CRD), consisting of six treatment concentrations of NaCl i.e., 0 ppm, 2,000 ppm;
4,000 ppm; 6,000 ppm; 8,000 ppm; 10,000 ppm respectively. The results showed
real effects of the treatment on the leaf area, length of the root, wet and dry
weight, but had no real effect on the parameter of the number of chlorophyll.
The whole treatment began to to affect the growth of mustard greens on the
concentration of 4,000 ppm of NaCl. The range of tolerance of mustard green
toward NaCl salt concentration was between 2,000 ppm – 10,000 ppm of NaCl.
