Increasing Soybean (Glycine max L) Drought Resistance With Osmolit Sorbitol

Efforts to increase soybean production has been pursued for years in Indonesia through the process of
intensification and extensification. Increased production through intensification of increasing grain yield per
hectare, among others includes the improvement of cultivation system such as the use of cultivars that have
superior resistance to drought. Increased soybean production has been through the expansion of planting areas
utilizing available idle dry land. However, one of the constraints faced in dryland agriculture was the limited
water supply due to low intensity of rainfall that leads to low crop production. In order to ensure that soybeans
are cultivated on dry land remains capable of high production, it is necessary to physiologically engineered the
soybean with an open stomata. The study was conducted in the greenhouse of Balai Penelitian Tanaman
Serealia (BALITSEREAL) Maros, Sulawesi, Indonesia with a completely randomized block design h factorial
pattern. The first factor was the water stress stadia while the second was the amount of sorbitol osmolit
concentration application. Results indicated that there was an interaction between the plant height growth and
number of leaves between the water clamping time and concentration of the osmolit sorbitol. The vegetative
stage especially during flowering and pod formation was inhibited when the water was clamped, but by spraying
osmolit sorbitol, soybean growth interms of its height and number of leaves was enhanced. This study implies
that the application of osmolit sorbitol may enhance the drought resistance of soybean growth. Future research
suggested that more work should be done on the application of osmolit sorbital to other agriculture crops to
increase their drought resistance in the drylands.
