Nutrient status of cauliflower in soils irrigated by sewage and tubewell water

Samples of soil and leaves as well as curds of cauliflower were collected from thirty rune locations and were analyzed for nitrogen, phosphorus, potassium, calcium, magnesium and sulphur. In soils, potassium content was higher in sludge applied fields whereas phosphorus content was more in sewage water irrigated fields. The concentrations of P, K, Mg and S in leaves of cauliflower were higher in sludge applied and sewage irrigated fields than the FYM applied and tubewell irrigated fields. Similar was the trend for P, K, Ca, Mg and S in curds of cauliflower. Inspite of addition of FYM, sewage sludge and sewage irrigation, a significant number of plant samples were below the critical levels in all the nutrients except nitrogen.
