Uji Asosiasi Bakteri Rhizobium Terseleksi dengan Leguminosa Pakan dalam Kondisi Tercekam Salin
ABSTRACT: The research aim was
to investigate association selected rhizobium bacteria with legumes in salinity
stress. Plant media was salin soil that have EC = 20.45 mmhos/cm which taken
from Morosari beach, Sayung, Demak. Rhizobium isolate applied was tolerant to
12.000 ppm of NaCl that equaled to electrical conductivity of 20 mmhos/cm. The
research was carried out in green house of Laboratory of Forage Science
Diponegoro University Semarang. The design arranged was completely randomized
design with factorial design 2 x 4 in 3 repeatations. First factor was kind of
legumes, T1 = lamtoro (Leucaena leucocephala); T2 = turi (Sesbania
grandiflora). and second factor was kind of rhizobium isolates, I1 = without
isolate; I2 = rhizobium that was isolated from lamtoro, I3 = rhizobium that was
isolated from turi; I4 = combination isolate from lamtoro and turi. The crop
growth was observed up to 10 weeks of age. The parameters were 1) crops heigh;
2) sum of leaf crops; 3) fresh weight production; 4) dry weight production; 5)
amount and fresh weigh of effective root nodules. The study showed the growth
and production of turi in saline media of EC 20.45 mmhos/cm was higher than
lamtoro. Root nodule of turi was formed, but lamtoro was not. Turi was more
tolerant than lamtoro at very saline media.
