Light Requirements
Corchorus olitorius L. var. incisifolius Asch. & Schweinf. thrives in full sunlight. For optimal growth and productivity, the plant requires at least six hours of direct sunlight each day. In low light, the plant tends to grow spindly and produce less foliage. As such, it is recommended to grow the plant in a location that receives plenty of direct sunlight.
Temperature Requirements
The optimal temperature range for the growth of Corchorus olitorius L. var. incisifolius Asch. & Schweinf. is between 20°C and 30°C. The plant is considered a warm-season crop and does not tolerate frost or low temperatures. The ideal temperature for the plant is around 25°C, and temperatures above this range may lead to decreased yields.
Soil Requirements
Corchorus olitorius L. var. incisifolius Asch. & Schweinf. prefers well-drained soils with a pH range between 6.0 and 7.5. The plant does not tolerate waterlogged soil or heavy clay soils. For optimal growth, it is recommended to add organic matter and nutrients to the soil before planting. The plant is sensitive to high levels of salinity and may not grow well in soils with high salt content.
Cultivation of Corchorus olitorius L. var. incisifolius Asch. & Schweinf.
Corchorus olitorius L. var. incisifolius Asch. & Schweinf., also known as Jew's mallow, is a tropical plant that prefers a warm climate. It can be grown throughout the year in equatorial zones or during the warm season in other regions. This plant can grow in sandy soil but thrives in deep, well-draining soil that is enriched with organic matter.
When planting Jew's mallow seeds, plant them 1-2 cm deep in the soil. Ensure that the soil stays moist throughout the germination and seedling phase, which can take anywhere from one to two weeks. The recommended spacing between plants is 15-20 cm, with rows spacing of 40-60 cm.
Watering Needs
Jew's mallow requires regular watering, and the soil should be consistently moist. However, ensure that the soil is not waterlogged, as this can lead to root rot. During the dry season, increase the frequency of watering to at least once a day.
Fertilization
Apply a balanced fertilizer six weeks after planting and monthly thereafter. The recommended amount of fertilizer is 50-70 kg per hectare. When applying the fertilizer, take care not to let it come into contact with the leaves or stalks, as this can lead to burning.
Pruning
Regular pruning is necessary to promote healthy growth and a steady yield. The best time to prune is during the flowering stage, as this encourages the growth of new stems and leaves. Prune off the growing tips to encourage bushy growth and the development of lateral shoots.
During the harvesting phase, remove the entire plant at the base to prevent disease and to promote the growth of new plants. It's best to harvest the leaves when they are young and tender, as they can become tough and fibrous as they mature.
Propagation of Corchorus olitorius L. var. incisifolius Asch. & Schweinf.
Corchorus olitorius L. var. incisifolius Asch. & Schweinf., also known as jute mallow or Egyptian spinach, is a leafy plant that is commonly used in salads, stews, and soups in various parts of the world. To cultivate this plant, you can propagate it through different methods such as seeds, cuttings, and division.
Propagation by Seeds
The most common propagation method for Corchorus olitorius L. var. incisifolius Asch. & Schweinf. is through seeds. To get started, collect seeds from mature and fully developed fruits. Once you have the seeds, treat them with an appropriate fungicide to prevent fungal infection.
Afterward, sow the seeds in well-draining soil in a nursery bed or seed tray. The optimal temperature for germination is between 20-25°C. Water the seeds regularly to keep the soil moist but not waterlogged. The seeds should germinate within seven to ten days.
Propagation by Cuttings
Corchorus olitorius L. var. incisifolius Asch. & Schweinf. can also be propagated through stem cuttings. To propagate through cuttings, select healthy and disease-free stems, and make cuttings that are 15-20cm long. Remove any leaves and side shoots from the bottom half of the cuttings.
Prepare a potting mixture of sand and garden soil or vermiculite in a ratio of 1:1. Dip the cuttings in rooting hormone powder and plant them in the prepared potting mixture, leaving only the top few leaves exposed. Water the cuttings regularly to keep the soil moist and place them in a shaded area. The cuttings should develop roots in about three to four weeks.
Propagation by Division
You can propagate Corchorus olitorius L. var. incisifolius Asch. & Schweinf. through division as well. This method works best for mature plants that are a few years old, as they tend to develop a dense root structure. To propagate through division, carefully dig up the plant and separate the clump into several sections.
Plant each divided section in well-draining soil and water it regularly to keep the soil moist. Place the newly divided plants in a shaded area until they become established.
Propagation of Corchorus olitorius L. var. incisifolius Asch. & Schweinf. requires patience, time, and effort. But with the right techniques and care, you can easily grow this nutritious plant in your garden.
