THE APPLICATION OF PEATY MINERAL SOIL WATER IN IMPROVING THE ADAPTABILITY OF BLACK SOYBEAN TOWARD ALUMINIUM STRESS ON TIDAL MINERAL SOIL WITH SATURATED WATER CULTURE
ABSTRACT: Soybean development
in mineral soils of tidal land is hindered by aluminum toxicity. Modification of growing environment and the
use of tolerant variety are feasible alternatives. Experiment was conducted
with several objectives (1) to identify growth and yield of black soybean at
depths of water table, (2) to identify growth and yield of black soybean as
effected by application of ameliorants, (3) to identify growth and yield of black
soybean, (4) to identify interaction between depth of water table, type of
ameliorant, and black soybean variety. The experiment was mineral soils with
watershed B type of tidal land in South Sumatera on May to August 2014. Factors investigated were depth of water
table (10 and 20 cm), (Tanggamus – as control, Cikuray, Ceneng) and ameliorant
type (river water, peaty mineral soil water, and high-tide water). These
factors were arranged in a Split-plot Design.The results demonstrated that, for
growing black soybean, soils with water table depth of 20 cm was better than
those of 10 cm, peaty mineral soil water ameliorant was better than river water
or high-tide water ameliorant, Ceneng produced higher yield, but not to those
of Cikuray. There was no interaction
between surface water depth, ameliorant and variety.
