Reseacher of IPB: The Best Hermetic Plastic Package to Store the Soybean Seeds
Damage to soybean seeds could occur during the seed processing, whether during the harvest, the threshing, and the drying. The speed at which threshing and bouncing the seeds when released on the pods could cause the damage to the seeds that could degrade the quality.
Reseacher from the Department of Agricultural Engineering and Biosystem, Bogor Agricultural University (IPB), Dr.Ir. Emmy Darmawati, explained that the decline in the quality of the soybean seeds during the faster storage took place compared to other plant seeds. As a result, there was a decrease in the seed germination. So that, the soybean seeds to be planted should be stored in a favorable environment.
“The selection of the packaging material is very important, so that the seed moisture content does not change during the storage and the viability of the seed can be maintained. The development of the packaging material is directed by the need to reduce the environmental influences and to increase the shelf life,” she said.
She and her fellow researchers namely Irna Dwi Destiana and Lilik Pujantoro examined the effect of some plastic packaging on the quality of the soybean seeds during the storage.
“We examine the soybean seeds of the varieties of Argomulyo. The seeds are processed and dried to moisture the content of less than 10 percent. The seeds are stored in three types of the plastic packaging i.e.. the HDPE, the hermetic plastic, and the vacuum plastic for 6 months in the warehouse with the room temperature. We want to get the best packaging type for the soybean seed packaging,” she said.
This researcher explained that the type of packaging significantly affected the moisture content and the weight gain during the storage. The water content of the seeds on the HDPE packaging increased during the storage and was closely related to the weight gain. The speed of the engine rotation (rpm) of the threshing also greatly affected the broken grains, where the high rpm had a close relation with the increase of the broken grains.
“From the experiments conducted it is known that the hermetic plastic packaging has the best ability to maintain the water content and to inhibit the addition of the soybean seed weight stored. After the plastic is hermetic, the second position is the vacuum plastic packaging and the last is the HDPE. The soybean seeds stored in the plastic of the HDPE, the hermetic plastic, and the vacuum plastic have a germination of ≥ 70% to 6 months storage and the water content of < 10%,” she said. (IR/Zul)
