Temperature Requirements
The plant grows best in an environment with cool summers and cold winters. It has been observed to grow best in temperatures ranging from 60-70° F, and it is tolerant of temperatures dipping below freezing. Springtime temperatures of around 55°F are optimal for germination.
Soil Requirements
Zizania palustris L. var. interior (Fassett) Dore prefers to grow in wet or flooded soils. The ideal soil pH range is between 6.0 and 7.5. The plant also requires high nutrient availability, particularly for nitrogen and phosphorus. The rhizomes should be planted in soil that is loose and well-draining to avoid waterlogging.
Cultivation Methods
Zizania palustris L. var. interior (Fassett) Dore, commonly known as Northern Wild Rice, is an aquatic plant that thrives in wetlands such as marshes, bogs, and shallow lakes. To cultivate it, you need to plant the seeds in shallow water with soil that is rich in organic matter like peat or compost.
Before planting, you need to hand-seed the rice in the area that has a depth of up to 15cm of water and allow it to germinate for 7 to 10 days before flooding the plot. You can also plant pre-germinated seedlings of up to seven days in a tray and grow them before transplanting them to the wetland area.
It is prudent to clear all weeds and other plants that may compete with the wild rice for nutrients and water, especially in the initial growth stages. Do not add any chemicals like herbicides or pesticides to the wetland area as they may harm the plant, other aquatic life, and promote environmental degradation.
Watering Needs
Zizania palustris L. var. interior (Fassett) Dore is mostly a submerged aquatic plant. Therefore, it does not require frequent or any watering once the rice plot is flooded with water. The plant derives its nutrients and moisture from the surrounding water.
It is, however, essential to maintain the water level in the rice paddies at about 10 to 15cm throughout the growing season. Insufficient or excess water can negatively affect the germination and growth of the wild rice plant or cause waterlogging, which may lead to root rot or diseases.
Monitor the moisture content around the plot and alter the water levels accordingly.
Fertilization
Northern Wild Rice plant is relatively low maintenance and does not require much fertilization.
However, you can opt to fertilize the rice paddies with organic matter such as compost, animal manure, and green manure crops like legumes to supplement the soil's nutrients and promote plant growth.
Fertilizers such as chemical NPK fertilizers should be avoided as they may have adverse effects on the plants and surrounding ecosystems.
Apply the organic matter or manure to the rice paddies before planting and avoid applying any additional fertilizer during the growing season.
Pruning
The Northern Wild Rice plant does not require pruning as its growth takes place under the water.
However, it is essential to carry out maintenance practices like removing any weeds or unwanted plants that may compete with the wild rice for nutrients and water. Weed management is crucial as it promotes the growth of the wild rice and reduces the chances of rice crop failure.
If the wild rice plot's water levels are not enough, you can remove the excess growth that may have emerged above the water to regulate moisture loss.
Care should be taken to ensure that the practice does not cause any harm or damage to the plant's growth or the wetland ecosystem.
Propagation of Zizania Palustris L. var. Interior (Fassett) Dore
Zizania palustris L. var. interior (Fassett) Dore, commonly known as northern wild rice, is a plant that is mostly grown in wetland habitats, particularly in shallow water. Propagation of this plant can be done by using different methods, which include:
Seed Propagation
One of the most common and easiest ways to propagate Zizania palustris is through seed propagation. This method involves collecting ripe seeds from mature plants and storing them in a cool and dry place until planting time. The seeds can be sown directly into the desired location where the plant is to be grown. The best planting time for this method is late spring to early summer. Seed propagation results in a high yield of plants within a short time.
Rootstock Division
Another method of propagating Zizania palustris is through division of rootstock. In this method, mature plants are dug out of the soil, and the roots are carefully divided into sections, each with a sufficient number of roots and shoots to produce a new plant. Rootstock division is best done during the dormant season, which is from late fall to early spring. This method is suitable for propagating mature plants that have already established themselves in the desired location.
Cuttings Propagation
Cuttings propagation of Zizania palustris is also possible, but it is not a common method. This method involves taking stem cuttings from mature plants and rooting them in a medium containing water or a suitable rooting hormone. Once the cuttings have developed sufficient roots, they can be transplanted into the desired location. Cuttings propagation is a slow method of propagation and is not suitable for commercial cultivation of Zizania palustris.
In summary, Zizania Palustris L. var. Interior (Fassett) Dore propagation can be achieved through seed propagation, rootstock division, and cuttings propagation. Seed propagation is the most common and easiest method. Rootstock division is suitable for mature plants that have established themselves in the desired location, and cuttings propagation is not a common method.
