Introduction

Yam seeds (Pachyrhizus erosus L.Urban) are an important crop in many parts of the world, particularly in tropical regions. However, the viability of yam seeds is often affected by various factors, including the length of drying and storage. In Indonesia, research on the effect of drying and storage on the viability of yam seeds is still limited. Therefore, a study was conducted at the Biology Laboratory, USU Faculty of Agriculture to investigate the effect of drying and storage on the viability of yam seeds.

Methodology

The study used a factorial complete randomized design with two factors: the duration of drying with four levels (K0 = 0 days, K1 = 1 day, K2 = 2 days, and K3 = 3 days) and the storage period with five levels (S0 = 0 weeks, S1 = 2 weeks, S2 = 4 weeks, S3 = 6 weeks, and S4 = 8 weeks). The study was conducted at an altitude of +25 m above sea level in March - May 2010.

Results

The results showed that the length of drying significantly affected the observed parameters, namely the water content of the seeds, the germination rate, and the percentage of germination. Meanwhile, the length of storage significantly affects the germination rate, the percentage of germination, and the fresh weight of sprouts. The interaction between the length of drying and the length of storage also significantly affects the germination rate, the percentage of germination, and the fresh weight of the sprouts.

Discussion

The study reveals that the length of drying and storage has an important role in determining the viability of yam seeds. The results of this study are consistent with previous studies that have shown that drying and storage can affect the viability of seeds.

Long Drying

Drying helps reduce the water content of seeds, thereby reducing the risk of damage caused by fungi and bacteria. The longer the drying time, the lower the water content of the seeds, and the better the viability. However, too long drying can cause seed damage and reduce the germination rate.

The right drying can increase the germination rate, because dry seeds are easier to absorb water and germinate. However, too long drying can cause seed damage and reduce the germination rate. Optimal drying can increase the percentage of germination, because more seeds can germinate.

Long Storage

Long storage affects the ability of seeds to germinate. The longer it is stored, the germination rate decreases, because the seed component is important for germination to experience degradation. The length of storage also affects the percentage of germination. Seeds that are stored for too long will have a lower percentage of germination.

The length of storage affects the growth of sprouts. Seeds that are stored for too long will produce smaller and weaker sprouts.

Long Interaction of Drying and Storage

The results showed that the interaction between the length of drying and the length of storage also affected the viability of seeds. The time combination of drying and the exact time of storage can increase the viability of yam seeds.

Implications for Farmers and Researchers

Knowledge of the effect of the length of drying and storage on the viability of yam seeds is very important for farmers and researchers.

Farmers

Farmers can use this information to determine optimal seed storage strategies, so that seeds still have high viability and can produce healthy plants.

Researchers

Researchers can use this information as a basis for further research, for example to find ways to increase the viability of yam seeds with better drying and storage techniques.

Conclusion

The length of drying and storage has a significant influence on the viability of yam seeds. The time combination of drying and the exact time of storage can increase seed viability and produce healthy plants. This study provides useful information for farmers and researchers to increase yam production and maintain biodiversity.

Recommendations

Based on the results of this study, the following recommendations are made:

Farmers should use optimal drying and storage techniques to increase the viability of yam seeds.
Researchers should conduct further studies to find ways to increase the viability of yam seeds with better drying and storage techniques.
The government should provide support for farmers and researchers to increase yam production and maintain biodiversity.

Limitations of the Study

This study has several limitations, including:

The study was conducted at a single location, and the results may not be applicable to other locations.
The study only investigated the effect of drying and storage on the viability of yam seeds, and did not investigate other factors that may affect seed viability.

Future Research Directions

Future research should investigate the following:

The effect of other factors, such as temperature and humidity, on the viability of yam seeds.
The development of new drying and storage techniques to increase the viability of yam seeds.
The impact of yam production on the environment and human health.

Q: What is the importance of drying and storage in the viability of yam seeds?

A: Drying and storage are crucial factors that affect the viability of yam seeds. Proper drying and storage can increase the germination rate and percentage of germination, while improper drying and storage can lead to seed damage and reduced viability.

Q: How long should yam seeds be dried before storage?

A: The optimal drying time for yam seeds is between 1-3 days. Drying for longer than 3 days can cause seed damage and reduce viability.

Q: What is the effect of storage duration on the viability of yam seeds?

A: The length of storage affects the germination rate and percentage of germination. Seeds stored for too long will have a lower germination rate and percentage of germination.

Q: Can the interaction between drying and storage affect the viability of yam seeds?

A: Yes, the interaction between drying and storage can affect the viability of yam seeds. The time combination of drying and the exact time of storage can increase the viability of yam seeds.

Q: How can farmers use this information to improve yam production?

A: Farmers can use this information to determine optimal seed storage strategies, so that seeds still have high viability and can produce healthy plants.

Q: Can researchers use this information to develop new drying and storage techniques?

A: Yes, researchers can use this information as a basis for further research, for example to find ways to increase the viability of yam seeds with better drying and storage techniques.

Q: What are the implications of this study for the environment and human health?

A: This study provides useful information for farmers and researchers to increase yam production and maintain biodiversity. Proper drying and storage can also reduce the risk of seed-borne diseases and pests.

Q: What are the limitations of this study?

A: This study has several limitations, including the study was conducted at a single location, and the results may not be applicable to other locations.
