India has shown a remarkable progress in recent years and has attained self sufficiency in food staples. The radish (Raphanus sativus) is an edible root vegetable of the Brassicaceae family that was domesticated in Europe in pre- Roman times. In the Jaunpur city of Uttar Pradesh, a variety known newar or jaunpuri is grown which attains enormous size with a length of up to 75-90 cm and a girth of 50-60 cm, and may weigh up to 5-15 kg, or even more. However, this was not conspicuous in another cultivar of radish i.e. pusa chetki growing at the same site. It was found that the physico-chemical properties of irrigated water, soil and microbial population, supported the root growth of newar 112.5% (length), 133.3% (girth) and 2077.5% (biomass) more than that of pusa chetki. Among the two selected sites (M. N. Khan and Siddiquepur), Mandi Nasheeb Khan (experimental site) provided suitable environment for better growth of cv. newar of radish.
