| dc.description.abstract | Enhancement soybean production can be done by utilizing suboptimal land,
including saline land due to the limited agricultural land. However salinity
becomes the limiting factor soybean growth, which inhibits growth impacting
yield decline and the worst conditions can caused crop failure. This research
aimed to assess the effect of ascorbic acid and gibberellins in overcome the
adverse effects of salinity on two soybean genotypes (Glycine max (L.) Merrill).
This research uses the Split-Split Plot Design which consists of three factors with
three replications, as the main plot i.e. gibberellin concentration consisting of: G0
(without gibberellins) and G1 (100 ppm), as the subplot i.e. genotypes consisting
of: V1 (Non-Selection) and V2 (Selection) and as the sub-sub plot i.e. ascorbic
acid concentration consisting of: A0 (without ascorbic acid), A1 (200 ppm),
A2 (400 ppm) and A3 (600 ppm). The results showed that the ascorbic acid
concentration significantly increase the weight of 100 grain, plant height ages 2, 6
and 8 week after planting (WAP) and the number of productive branches where
the best results are obtained up to a concentration of 200 ppm and a decrease in
the concentration of 400 and 600 ppm. Soybean genotypes Non Selection
significantly had a higher number of productive branches as compared with
soybean genotypes Selection but generates the highest number of empty pods.
Giving of gibberellin 100 ppm do not increased production but significantly
increase plant height ages 6 and 8 WAP and the number of productive branches.
Interaction between the concentration of gibberellin and ascorbic acid do not
increased production but significantly increase the content of chlorophyll b and
accelerate harvest age, the best combination is found on the giving of gibberellin
100 ppm and ascorbic acid 600 ppm. While the interaction between the
concentration of gibberellins, genotypes and ascorbic acid not significant effect on
all components of growth and yield. | en_US |
