Soil and Plant Analysis

Management of poor quality irrigation waters

a. Saline water
1.Crop management

Growing crops that are tolerant high level soil salinity e.g.: Cotton, Ragi, Barley, sugar beat, Beet root, curry leaf, Bermuda grass, saline grass, spinach etc.
Crops that are tolerant to soil salinity at medium level are paddy, wheat, onion, maize, sunflower, castor, grape, pomegranate, tomato, cabbage and potato.
Crops that are tolerant to low level of soil salinity are garden beans, Reddish, lime etc. Black gram and green gram are sensitive to soil salinity.
Crops are to be chosen based on the soil salinity level.
