Abstract

In tropical and semi-tropical climates, the preservation of oilseeds is important for the preservation of germination ability and quality. When the oilseeds are not kept under proper storage conditions immediately after harvest, they immediately begin to deteriorate and lose their quality. This study was conducted in Adana province conditions with a semi-tropical climate type to determine the effects of different storage conditions on soybean seed quality. Trials, storage and laboratory studies were organized and analyzed in factorial coincidence parcels with 2 years and 3 repetitions according to the factorial trial pattern of 25. In the study, factors such as storage time (7 and 9 months), storage condition (traditional warehouse, cold storage warehouse), packaging material (PE sack, vacuum bag) and different large soybean variety (Yeşilsoy, Nazlican) have been determined to affect oil, protein and germination ability on soy seed stocks. At the end of the study, it was determined that the storage time and the variety had a statistically significant level of p ≤ 0.01 on fat, protein and germination rates. At the same time, it was determined that the storage condition p ≤ 0.01 and the package material p ≤ 0.05 were effective on germination, but these two factors had no statistical effect on fat and protein. When the data were evaluated, it was determined that the worst results were obtained from storage with “Traditional warehouse + PE sack” for both varieties in soy storage. In this storage, the very high germination rates of the Yeşilsoy (93.5%) and Nazlican (93%) varieties at the beginning of storage decreased by 56% and 45.83% respectively after 7 months of storage. At the end of 9 months of storage, it was determined that it decreased by 50.33% and 42.67%, respectively. As a result, in the storage of soy; it is determined that the ability to germinate is more protected than other issues provided that small seed soy varieties are preferred, stored in cold storage warehouse and storage time is not more than 7 months. In addition, when the cost as package material is taken into consideration in cold storage warehouse conditions, it is believed that PE material can be used instead of vacuum bag. It is thought that the storage conditions change according to the type and varieties of oilseed and these conditions should be determined by taking into account the environmental conditions according to the varieties.
