Cultivation Of Radish

Nutritive Value: Radish is one of the most preferred vegetable for salads. Radish contains 94 percent water, 3.4 percent carbohydrates, 0.7 percent proteins and 0.8 percent fibers, 0.6 percent minerals like calcium, phosphorus and iron, and is rich in vitamins A and C.

Soil and Climate: Radish can be grown in loose, porous, deep and well drained soil. Compact and hard soil is not good for the growth and development of radish as its shape does not remain normal in that type of soil. It is a cool season crop. A temperature of 20 °C to 25 °C is ideal for the growth and development of the root.

Important Varieties: Pusa Reshmi, Arka Nishanth and Japanese White are important varieties of radish grown in South India.

Planting and Irrigation: Radish is grown mostly in the winter season. Seeds are sown at 1 to 2 cm depth in the soil followed by irrigation. Irrigation should be provided 4 to 5 day intervals in the summer season and 7 to 8 day intervals in the winter season.

Plant Protection: Radish is mostly attacked by mustard saw fly insects that can be controlled by spraying neem seed extract on the vegetable.

Harvesting: Radish becomes ready for harvesting 45 to 60 days after sowing of the seeds. Harvesting is done by uprooting the plant. If harvesting is delayed, the root becomes mature and the central part of radish turns spongy and pithy and becomes useless for eating.
