In the highlands of Lembang, West Java, researchers have explored an innovative method to enhance shallot cultivation by introducing beneficial fungi known as dark septate endophytes (DSE). These fungi form symbiotic relationships with plants, potentially improving growth and yield.
The study focused on a hybrid of shallots and bunching onions (Allium fistulosum L. x Allium cepa L. var. aggregatum), applying three DSE strains: Dendrothyrium sp., Curvularia sp., and Cladosporium sp. Over a 16-week period, researchers monitored various growth parameters, including plant height, number of leaves, and bulb development.
Findings revealed that DSE application influenced the growth patterns of the crossed-shallots. Notably, the Cladosporium sp. strain increased plant height and bulb number, while the Curvularia sp. strain enhanced plant height, pseudo-stem diameter, leaf diameter, and fresh weight. Interestingly, all treatments extended the harvest time to 16 weeks, longer than the typical 8–13 weeks for standard shallots, suggesting a potential for larger yields.
This research highlights the promise of DSE in sustainable agriculture, offering a natural means to boost crop performance. For farmers in regions like West Java, integrating such beneficial fungi could lead to more robust and productive shallot harvests.
