In this blog post, we’ll explore everything you need to know about growing Norland potatoes, focusing on their key plant traits, growing habits, and tips for ensuring a successful crop.

Overview of Norland Potatoes

Norland potatoes are an early-maturing red-skinned variety, popular for their smooth texture and suitability for a wide range of culinary uses. This versatile potato variety performs well in many climates, making it a go-to choice for both small-scale gardeners and large agricultural operations. Below, we will dive into the key plant characteristics that make Norland potatoes stand out.

Key Plant Characteristics of Norland Potatoes

Maturity: Early to Intermediate

One of the primary advantages of Norland potatoes is their early maturity, which typically falls in the intermediate to late range. Growers can expect to harvest Norland potatoes days to maturity is as little as 70 to 90 days after planting, depending on growing conditions. This early-maturing nature makes them an excellent choice for regions with shorter growing seasons or for those looking to enjoy fresh potatoes early in the summer.

For gardeners interested in a staggered harvest, Norland potatoes can be planted early in the season and followed by later-maturing varieties to extend the potato harvest period.

Growth Habit: Semi-Erect

Norland potatoes have a semi-erect growth habit, which means the plants grow relatively upright but may spread slightly as they mature. This growth style helps the plants maintain good air circulation, reducing the likelihood of fungal diseases and encouraging healthy growth.

The semi-erect habit of Norland potatoes also makes them easier to manage in the garden, as they require less space than sprawling varieties. However, to prevent tubers from being exposed to sunlight and turning green, it’s essential to hill the soil around the base of the plants as they grow.

Foliage Cover: Good

Another beneficial trait of Norland potatoes is their good foliage cover. The dense, leafy canopy not only protects the tubers from sunlight but also helps retain moisture in the soil, reducing the need for frequent watering. This foliage cover provides a natural shield against some common pests and diseases, making Norland potatoes a relatively low-maintenance crop.

A well-covered plant also means better weed suppression, as the thick foliage will outcompete many unwanted plants. This results in healthier growth and less time spent weeding for the grower.

A vibrant flower display usually suggests that the plant is thriving and likely to produce a good crop.

Pollen Fertility: High

One interesting trait of Norland potatoes is their high pollen fertility, which means that these plants produce a large quantity of viable pollen. While Norland potatoes are typically grown from seed potatoes (tubers), high pollen fertility can be beneficial for breeding purposes or for gardeners who are interested in experimenting with potato seeds. High pollen fertility may also increase the likelihood of cross-pollination with other nearby potato varieties, although this doesn’t impact tuber production in the current season.

Growing and Harvesting Norland Potatoes

Soil Preparation

To grow Norland potatoes successfully, start by selecting well-drained, loose soil. Potatoes do best in soil with a pH of 5.0 to 7.0. Loosening the soil to a depth of 12 to 18 inches will allow the tubers to develop fully. Adding compost or well-rotted manure to the soil will improve its fertility and structure.

Planting and Spacing

Plant Norland seed potatoes in rows, spaced 12 to 15 inches apart, with 30 inches between rows. The seed pieces should be buried 3 to 5 inches deep in the soil. Planting should be done in early spring once the danger of frost has passed, but the soil is still cool.

Hilling and Maintenance

As the Norland potato plants grow, hill the soil around the base of the plant to cover the developing tubers and prevent them from turning green. This also encourages more tuber production.

Regularly check for pests like Colorado potato beetles, aphids, and wireworms. Norland potatoes are generally resistant to many common potato diseases, but it’s still a good practice to rotate crops and maintain good garden hygiene.

Harvesting

Norland potatoes can be harvested early as “new potatoes” or left in the ground for a more mature crop. For new potatoes, harvest about 70 to 80 days after planting. For a more mature crop, wait until the foliage begins to die back before harvesting. Gently dig around the plants to avoid damaging the tubers.

Norland potatoes are classified as a fairly firm, multi-purpose type, which means they hold their shape well when cooked. This makes them an excellent choice for a wide range of cooking methods, including boiling, steaming, roasting, and frying. Their firm texture ensures that they don’t fall apart easily during cooking, making them particularly well-suited for dishes like potato salads, casseroles, or soups where you want the potatoes to maintain their form.

Because of their multi-purpose nature, Norland potatoes offer versatility in the kitchen. Whether you’re looking to mash, roast, or fry, their consistent texture makes them a reliable choice for various recipes.

After-Cooking Blackening: Trace

One of the more favorable traits of Norland potatoes is their trace after-cooking blackening. After-cooking blackening refers to the discoloration that some potatoes may exhibit after being cooked and left to cool. Potatoes that blacken after cooking can lose some of their visual appeal, especially in dishes where presentation is key.

Norland potatoes have minimal after-cooking blackening, which means that they retain their attractive appearance after cooking. This makes them ideal for dishes where the potatoes need to be prepared in advance and then served later, such as in buffet settings or meal prep for family dinners.

Dry Matter Content: Medium to Medium-High

The dry matter content of a potato refers to the proportion of solids (mainly starch) in the tuber, as opposed to water. Norland potatoes have a medium to medium-high dry matter content, making them a balanced potato variety for both moist and fluffy textures. Potatoes with higher dry matter content tend to be fluffier and drier when cooked, while those with lower dry matter content are waxier and moister.

Norland’s medium to medium-high dry matter content makes them great for achieving a fluffy texture when baked or roasted, while still retaining some moisture, which is ideal for boiling or steaming.

Starch Content: Low to Medium-High

Norland potatoes have a low to medium-high starch content, giving them a middle ground between waxy and starchy potatoes. Potatoes with low starch content, often referred to as waxy potatoes, hold their shape well after cooking, while those with higher starch content are more prone to breaking apart, resulting in a fluffier texture.

Because Norland potatoes fall in the low to medium-high range for starch content, they can be used in a wide variety of dishes. For recipes requiring potatoes to retain their shape, such as scalloped potatoes or salads, Norland potatoes’ lower starch level helps keep them intact. On the other hand, their moderate starch content also allows them to achieve a light, fluffy consistency when mashed or baked.

Culinary Uses of Norland Potatoes

Thanks to their multi-purpose texture, Norland potatoes are incredibly versatile and can be used in various ways:

• Boiling and Steaming: Norland potatoes retain their shape well when boiled or steamed, making them ideal for potato salads or as a side dish served with butter and herbs.
• Roasting and Baking: The medium-high dry matter and starch content allow Norland potatoes to become crispy on the outside while maintaining a fluffy interior when roasted or baked.
• Mashing: Though they aren’t as starchy as russet potatoes, Norland potatoes still mash well, resulting in a smooth and slightly creamy texture.
• Frying: While they aren’t the go-to for frying, Norland potatoes can be used for home fries or hash browns where a fairly firm texture is desired.

Resistance to Fungal Diseases in Norland Potatoes

Norland potatoes are not only known for their high yield, large tubers, and excellent culinary qualities, but they also offer good resistance to various fungal diseases. This makes them a robust and reliable choice for farmers and gardeners, especially in regions prone to fungal outbreaks. We’ll explore Norland potatoes’ resistance to key fungal diseases, such as late blight, powdery scab, and wart, and how these traits benefit growers.

Resistance to Late Blight on Tubers: Medium to High

Norland potatoes offer medium to high resistance to late blight on tubers, a crucial trait for growers who face the threat of this devastating disease. Late blight, caused by the pathogen Phytophthora infestans, is notorious for rapidly destroying crops, especially during wet and humid conditions. It can affect both the foliage and tubers, leading to significant yield losses if not controlled.

Norland potatoes’ resistance to late blight on tubers means that even in environments where blight is present, the tubers themselves remain largely unaffected. This helps protect the quality and marketability of the harvested potatoes, making Norland a safer choice in blight-prone areas.

Resistance to Late Blight on Foliage: Medium to Medium-High

In terms of late blight resistance on foliage, Norland potatoes demonstrate medium to medium-high resistance. While not immune, this resistance level means that the plants can tolerate moderate exposure to the disease without a severe impact on overall growth and yield. Proper field management, such as using fungicides and practicing crop rotation, can further help minimize the spread of late blight in the foliage.

For growers, this resistance level provides a buffer against the rapid defoliation caused by late blight, allowing the plants to continue photosynthesizing and producing healthy tubers, even under moderate disease pressure.

Resistance to Powdery Scab (Spongospora subterranea): Medium to High

Norland potatoes exhibit medium to high resistance to powdery scab, a soil-borne disease caused by the pathogen Spongospora subterranea. Powdery scab affects the roots and tubers, causing unsightly scab-like lesions on the potato surface, which can reduce market value and increase susceptibility to secondary infections.

This medium to high resistance is advantageous for growers because it reduces the risk of powdery scab outbreaks, particularly in fields with a history of the disease or in regions where conditions favor its spread (cool, wet soils). The reduced likelihood of scab formation on tubers helps maintain the potatoes’ visual appeal, making them more suitable for commercial markets.

Resistance to Wart (Synchytrium endobioticum): Field Immune

One of the most impressive traits of Norland potatoes is their field immunity to wart, a serious disease caused by Synchytrium endobioticum. Wart is a quarantine disease in many parts of the world, as it can severely deform potato tubers, rendering them unmarketable and leading to long-term soil contamination.

How Norland’s Disease Resistance Benefits Growers

Norland potatoes’ field immunity to wart means they are highly resistant to infection, making them a reliable option for growers in regions where wart is a concern. This level of resistance also helps prevent the spread of wart in the field, contributing to healthier crop cycles and fewer quarantine restrictions.

The combination of medium to high resistance to late blight, powdery scab, and field immunity to wart offers several advantages for growers:

1. Reduced Crop Losses: Norland potatoes’ resistance to major fungal diseases minimizes the risk of crop failure, allowing for more consistent and higher yields.
2. Lowered Fungicide Use: While some disease management practices, such as fungicide applications, may still be necessary, Norland’s natural resistance reduces the need for excessive chemical treatments, helping to lower input costs and reduce environmental impact.
3. Enhanced Marketability: Tubers that are less affected by diseases like powdery scab and late blight maintain their appearance and quality, making them more appealing to buyers in both fresh markets and processing industries.
4. Field Safety and Sustainability: Wart immunity and resistance to soil-borne diseases like powdery scab help keep fields healthy for future crops, making Norland potatoes a sustainable choice for long-term agricultural planning.

Resistance to Bacterial Diseases in Norland Potatoes

Norland potatoes are not only known for their high yields and versatility in the kitchen but also for their resilience against certain bacterial diseases. One of the key bacterial threats to potatoes is common scab, caused by Streptomyces scabies. We’ll focus on Norland potatoes’ resistance to common scab and explain how this trait benefits growers and contributes to healthier, more marketable crops.

Resistance to Common Scab (Streptomyces scabies): Medium to High

Norland potatoes exhibit medium to high resistance to common scab, a widespread bacterial disease that affects potato tubers. Common scab causes rough, cork-like lesions on the surface of the tubers, which can significantly reduce the aesthetic and market value of the potatoes. While common scab does not usually affect the internal quality of the potato, its appearance can make tubers less desirable for fresh market sales.

The medium to high resistance of Norland potatoes to common scab means that they are better equipped to withstand infection compared to more susceptible varieties. While no potato is completely immune to common scab, Norland’s resistance helps reduce the severity and extent of scab lesions, leading to higher-quality tubers with a smoother appearance.

How Resistance to Common Scab Benefits Growers

The medium to high resistance of Norland potatoes to common scab offers several advantages for farmers and gardeners:

1. Improved Crop Quality: With reduced scab formation on tubers, Norland potatoes maintain a smoother, more appealing skin. This is particularly important for fresh market sales where appearance is a key factor.
2. Lower Economic Losses: Common scab can significantly diminish the marketability of potato crops, especially for those intended for direct consumer sales. Norland potatoes’ resistance helps minimize these losses by producing higher-quality tubers.
3. Reduced Reliance on Chemical Control: Although environmental conditions and soil management practices play a significant role in the development of common scab, growing resistant varieties like Norland potatoes can reduce the need for intensive chemical treatments. This lowers input costs and helps promote more sustainable farming practices.
4. Adaptability to Different Soil Conditions: Common scab thrives in alkaline soils, but Norland potatoes’ resistance means they can still perform well in such environments with proper crop management. This gives growers more flexibility in choosing planting sites without worrying as much about common scab outbreaks.

Resistance to Viral Diseases in Norland Potatoes

Norland potatoes are known for their strong resistance to various diseases, including viral infections that can severely impact potato crops. Viral diseases are often spread by aphids and other vectors, and they can reduce yield, quality, and overall plant health. We’ll explore Norland potatoes’ resistance to key viral diseases such as potato virus A, potato virus Y, and potato leaf roll virus, and explain how these traits benefit growers.

Resistance to Potato Virus A: High to Very High

Norland potatoes exhibit high to very high resistance to potato virus A (PVA). This virus primarily affects the foliage of potato plants, leading to reduced photosynthesis, stunted growth, and decreased yields. Plants infected with potato virus A can show mild to severe symptoms, including mottling and leaf curl.

Norland’s very high resistance to PVA makes it an excellent choice for growers in areas where this virus is common. The high level of resistance ensures that plants remain healthy, with minimal impact from the virus. This trait is particularly beneficial for maintaining both yield quantity and quality, as the plants can continue to grow and produce tubers with minimal interference from PVA.

Resistance to Potato Virus Y (Strain Not Specified): Medium

Norland potatoes have medium resistance to potato virus Y (PVY), one of the most damaging viral diseases affecting potato crops globally. PVY is responsible for a range of symptoms, depending on the strain, including mosaic patterns on leaves, leaf necrosis, and severe yield reductions. Some strains can also cause tuber necrosis, further impacting crop quality.

While Norland potatoes offer medium resistance to PVY, meaning they are not immune but can tolerate some level of infection, growers may need to implement additional control measures, such as insect management (to control aphids, which spread PVY) or planting certified virus-free seed potatoes. The moderate resistance of Norland potatoes can help reduce the severity of PVY infections, but in areas with heavy virus pressure, additional precautions may be necessary.

Resistance to Potato Leaf Roll Virus: Medium

Norland potatoes also show medium resistance to potato leaf roll virus (PLRV). This virus causes upward rolling of the leaves, stunted growth, and, in severe cases, reduced yields and smaller tubers. PLRV is primarily transmitted by aphids and can have long-lasting effects on the crop.

With medium resistance to PLRV, Norland potatoes can withstand some degree of infection, but careful management is still important to prevent outbreaks. In particular, controlling aphid populations and using virus-free seed potatoes can help reduce the risk of PLRV transmission. While Norland’s moderate resistance provides some protection, additional cultural and pest management practices are often required to fully protect the crop from the effects of PLRV.

How Norland’s Viral Disease Resistance Benefits Growers

The resistance of Norland potatoes to viral diseases offers several important advantages for farmers and gardeners:

1. Increased Yield and Quality: High resistance to potato virus A ensures that Norland potato plants remain healthy and productive, leading to better yields and tuber quality. With minimal damage from PVA, the crop is more likely to meet market standards.
2. Reduced Crop Losses: The medium resistance to PVY and PLRV provides some protection against these viruses, helping to mitigate crop losses even in areas where viral infections are common. However, growers may still need to employ integrated pest management strategies to keep virus levels in check.
3. Less Dependence on Chemical Controls: With high resistance to certain viruses, such as PVA, growers can reduce the need for chemical treatments targeting virus vectors like aphids. This helps lower production costs and supports more sustainable farming practices.
4. Enhanced Crop Resilience: By choosing a variety like Norland potatoes, which offer a good balance of resistance to viral diseases, growers can reduce the risk of widespread infection and improve the resilience of their crop, even in challenging growing conditions.

Conclusion

Norland potatoes are a versatile and reliable variety, offering high resistance to key diseases like potato virus A and common scab, along with medium to high resistance to fungal diseases such as late blight and powdery scab.
