Drought levels of several soybean’s variety (Glycine Max L. Merril)

Abstract. Demand for soybeans in Indonesia is very high however, the domestic production is
not sufficient enough for the community's needs for soybeans so it must be fulfilled through
imports. The slow rate of soybean's production improvement in Indonesia caused by national
low productivity that only reaches 1.30 tons/ha. While the potential increase in national
soybeans can reach 2.2 million tons/ha. This research aims to find out some soybean varieties
that are tolerant and sensitive to drought stress. This research was carried out at the Green
House Cereals Plant Hall in Maros Regency, which began in July to October 2018. This
research used factorial Randomized Group Design (RGD), Factor I is a soybean variety (V),
consists of 4 varieties, namely : V1 = Tanggamus (tolerant to drought stress), V2 = Wilis
variety (tolerant to drought stress), V3 = Anjasmoro variety (sensitive to drought stress), V4 =
Argomulyo variety (sensitive to drought stress). The second factor is drought stress level (K)
consists of 3 levels, namely: K1 = 80% field capacity, K2 = 60% field capacity, K3 = 40%
field capacity. The results obtained that there is a decrease in all characters of the seed yield up
to 50% along with the decrease in availability of groundwater in all tested varieties. The
Tanggamus variety as a tolerant variety is still able to maintain several characters better than
the other three varieties at 40% water availability, namely the number of pods, root length and
stomata density. There are interactions between several soybean varieties and the level of
drought stress on observations of plant growth and observation
