Increased Soybean Yield In Saline Soil With The Use Of Resistant Genotypes, Ascorbic Acid, And Arbuscular Mycorrhizal Fungi
Improve Soybean Yields in Saline Land: Integrated Solutions for the Future
Efforts to increase domestic soybean production continue to be carried out, one of which is by utilizing marginal land such as saline land. However, the high levels of salt in the saline land are the main obstacles in soybean cultivation. Soybeans planted on saline land experience osmotic, oxidative, and ion poisoning stress, as well as nutrient deficiencies. This causes low crop yields. The use of saline land for soybean cultivation is a promising approach to increase domestic soybean production, but it requires innovative solutions to overcome the challenges posed by salinity stress.
This study aims to find solutions to increase soybean production in saline land by utilizing salinity resistant genotypes, application of ascorbic acid, and inoculation of indigenous arbuscular mycorrhizhy (FMA). This research was conducted in three stages, each focusing on a different aspect of soybean cultivation in saline land.
First Stage: Selection of Salinity Resistant Genotypes
The first stage of this study focused on soybean mass selection to the fourth generation (F4) to get salinity resistant genotypes. This selection process was carried out in the saline land with a salinity level (DHL) of 5-6 mmhos/cm. Molecular analysis is a crucial step in identifying genes that play a role in salinity tolerance in selected soybeans. The selection results show progress, but plant production and heritability values are still unstable, possibly influenced by fluctuations in the level of soil salinity. Understanding the genetic basis of salinity tolerance is essential for developing effective breeding programs.
Second Stage: Exploration and Identification of Indigenous FMA
The second stage of this study focused on exploration and identification of FMA indigenous from saline land. Five Genus FMA with different characteristics successfully identified, namely *Glomus sp.1, Glomus sp.2, Glomus sp.3, Glomus sp.4, and Glomus sp.5 *. Research shows that the existence of FMA is influenced by the level of soil salinity. The higher the salt content, the less the number of spores and the ability of FMA to infect the host plant. This highlights the importance of understanding the relationship between FMA and soil salinity in saline land.
Third Stage: Testing the Effectiveness of FMA and Ascorbic Acid
The third stage of this study tested the effectiveness of FMA and the application of ascorbic acid in soybean genotype resistant to salinity. The study was conducted in three locations with different salinity levels (DHL 4-5 mmhos/cm, 5-6 mmhos/cm, and 6-7 mmhos/cm). The results show that soybean selected salinity resistant can grow and produce better than Grobogan varieties. The application of ascorbic acid has a positive effect on the growth and production of soybeans in the saline land. Ascorbic acid acts as an antioxidant that helps plants overcome oxidative stress due to salinity stress. FMA inoculation is also proven to increase soybean growth and production in saline land. FMA helps plants absorb water and nutrients more efficiently, thereby increasing growth and yields.
Conclusion
In conclusion, the use of salinity resistant genotypes, ascorbic acid applications, and indigenous FMA inoculation together proved effectively to increase soybean production in saline land. This study provides an integrated solution to overcome the constraints of soybean production in marginal land. With the application of this technology, it is expected to increase domestic soybean production and help achieve the target of soybean self-sufficiency in the future.
Future Directions
This study highlights the importance of integrated solutions in overcoming the challenges of soybean production in saline land. Future research should focus on scaling up the application of this technology to larger areas and exploring its potential in other marginal lands. Additionally, further research is needed to understand the long-term effects of FMA inoculation and ascorbic acid application on soybean production in saline land.
Implications
The findings of this study have significant implications for soybean production in saline land. The use of salinity resistant genotypes, ascorbic acid applications, and indigenous FMA inoculation can increase soybean yields and improve crop quality.
