Morphological Analysis And Production Of Sweet Potato Plants (Ipomea Batatas L. (Lamb)) In The Highlands And Lowlands Of North Sumatra
Introduction
Sweet potatoes (Ipomoea Batatas L. Lamb) are a staple crop in many parts of the world, including Indonesia. They are a rich source of essential nutrients, vitamins, and minerals, making them an excellent food choice for people of all ages. However, the production and morphology of sweet potatoes can vary greatly depending on the location, climate, and soil type. In North Sumatra, sweet potatoes are grown in both highland and lowland regions, with each region having its unique characteristics and challenges.
Research conducted by Dwi Sri Utari, under the guidance of Emmy Harso Kardhinata and Revandy I. M. Damanik, aimed to investigate the morphological analysis and production of sweet potatoes in the highlands and lowlands of North Sumatra. This study was conducted from March to August 2016, using a descriptive survey method and judgemental sampling techniques.
Research Methodology
The study was conducted in two research locations: Deli Serdang Regency, which represents the lowland regions, and Tanah Karo Regency, which represents the highlands. The research locations were chosen based on their geographical characteristics, climate, and soil type. The study used a descriptive survey method, which involved collecting data on the morphology and production of sweet potatoes in each location.
The sampling technique used was judgemental sampling, which involved selecting samples based on their representativeness of the population. The samples were selected based on their characteristics, such as soil type, climate, and location height.
Morphological Analysis
The morphological analysis of sweet potatoes in the highlands and lowlands of North Sumatra showed significant differences between the two regions. In the lowlands, sweet potatoes tend to have larger leaves and are more susceptible to pest attacks. In contrast, sweet potatoes grown in the highlands are smaller and more resistant to pest attacks due to the cooler weather.
The genetic nature of each genotype also plays a significant role in shaping the morphological characteristics of sweet potatoes. Genotype 1 and 2 of Deli Serdang showed a significant difference in terms of tubers and leaf thickness, while genotype 3 and 4 of the Karo soil showed better resistance to drought conditions.
Sweet Potato Production
The production of sweet potatoes in the highlands and lowlands of North Sumatra also showed significant differences between the two regions. In the lowlands, sweet potato production tends to be higher due to the more moist and warmer climate. In addition, the humidity of the soil is sufficient to support optimal sweet potato growth.
In contrast, sweet potato production in the highlands is lower due to the cooler weather and drier soil. However, the quality of the tubers can be better with a sweeter taste and a denser texture.
Factors Affecting Sweet Potato Production
Several factors affect the production of sweet potatoes in the highlands and lowlands of North Sumatra. These factors include soil fertility, fertilizer administration, and cultivation practices. Farmers who apply good agricultural techniques and use organic fertilizer consistently tend to get better harvests, both in the lowlands and highlands.
Conclusion
The research conducted by Dwi Sri Utari provided a clear picture of the morphological variations and production of sweet potato plants in two different ecosystems in North Sumatra. By understanding the different genotype characteristics, farmers can choose the most suitable type of sweet potato to be cultivated, according to existing environmental conditions.
It is hoped that this research can be a reference for the development of sweet potato agriculture in Indonesia, especially in optimizing agricultural products in various locations. The findings of this study can also be used to inform policy decisions and agricultural practices in the region.
Recommendations
Based on the findings of this study, the following recommendations are made:
- Genotype selection: Farmers should select the most suitable genotype of sweet potato based on the existing environmental conditions in their region.
- Soil fertility management: Farmers should manage soil fertility by using organic fertilizers and good agricultural practices to optimize sweet potato production.
- Cultivation practices: Farmers should adopt good cultivation practices, such as crop rotation and intercropping, to optimize sweet potato production.
- Climate change adaptation: Farmers should adapt to climate change by using drought-tolerant sweet potato varieties and implementing conservation agriculture practices.
By implementing these recommendations, farmers can optimize sweet potato production and improve the livelihoods of rural communities in North Sumatra.
Limitations of the Study
This study has several limitations, including:
- Small sample size: The study had a small sample size, which may not be representative of the entire population.
- Limited geographical scope: The study was conducted in only two research locations, which may not be representative of the entire region.
- Limited data collection: The study relied on secondary data, which may not be accurate or up-to-date.
Future studies should aim to address these limitations by increasing the sample size, expanding the geographical scope, and collecting primary data.
Future Research Directions
Future research should focus on the following areas:
- Genetic diversity of sweet potatoes: Further research should be conducted to investigate the genetic diversity of sweet potatoes in the highlands and lowlands of North Sumatra.
- Climate change impact on sweet potato production: Research should be conducted to investigate the impact of climate change on sweet potato production in the highlands and lowlands of North Sumatra.
- Sweet potato value chain development: Research should be conducted to investigate the development of the sweet potato value chain in North Sumatra, including post-harvest handling, processing, and marketing.
By addressing these research gaps, future studies can provide a more comprehensive understanding of the morphological analysis and production of sweet potatoes in the highlands and lowlands of North Sumatra.
