How to grow Radish
Radish (Raphanus sativus)
The radish is annual or biennial plant which belongs to the cabbage family (Brassicaceae). We cultivate it for its fleshy root. The stem resembles the carrot, its leaves are hairy and the root is fleshy. The shape can be spherical, conical or long, according to the variety. The radish contains vitamin C and is rich in fiber. We eat it raw, in salads and soups. The flavor is spicy.
Professional and amateur cultivation of Radish
Radishes mature very quickly and are very durable. We must first decide on the variety that we want to cultivate and then choose and prepare the site. Radishes prefer area with full sun or partial shade and loose - well-drained alkaline soils. Before planting, it is advisable to remove from the soil all the rocks. We can also add organic matter.
We sow radish seeds directly in the field. There are about 4300 radish seeds per 1 oz. of seeds (150 radish seeds per seed grammar). We need 33-44 lbs. (15-20 kg) of seed per hectare in seed depth from 0,6 to 1 inch (1.3 to 2.5 cm). We leave a distance of 8-11 inches (20-30 cm.) between rows and 1,5-3 inches (4-8 cm.) between plants. We can have an average yield of 10-15 tons per hectare.
We have to irrigate frequently so as to keep the soil moist. Irrigation generally boosts radishes development. We normally harvest the radishes when the roots reach 1 inch (2.5 cm.) in diameter. We can keep the radishes for 2 weeks in a cool dark place.
