ABSTRACT
Horseradish is native to Mediterranean regions but it is mainly cultivated in the United States of America such as in Pennsylvania, Oregon, Washington, Wisconsin and California. The cooked horseradish is high in nutritional value. It is a rich source of minerals like phosphorous, potassium, calcium and magnesium. It is a valuable remedy for those who are suffering from asthma, chest complaints, coughs, colic, rheumatism, scurvy, toothache, ulcers, circulation problems, venereal diseases and cancer. Although horseradish can grow on any type of soil from sandy to alluvial soils, the best growth takes place in deep loam soil high in organic matter. Number of factors such as planting material, soil fertility, irrigation facilities, growing region, rainfall and the cultural practices adopted by the growers affect the yield of horseradish. Horseradish can tolerate some insect-pests without any serious effect on yield and quality of roots. Flea beetles, caterpillars, false cinch bugs and diamondback larvae may cause defoliation of leaves.
