摘要：
Excess of cations such as sodium and anions like carbonate, bicarbonate and chloride present in irrigation water, increase soil pH, Electrical Conductivity (EC) and Exchangeable Sodium Percentage (ESP) affect the growth and yield of the crop. To realise these impacts two field experiments were conducted for poor quality irrigation water with different amendments. Field experiment (I) was conducted on sandy loam soil at Pandipalayam, TNPL, Tamil Nadu, India with treated paper mill effluent as irrigation source and experiment (II) was conducted on sandy clay loam soil at Vatamalaipalayam, Thudialur, Tamil Nadu, India with saline groundwater as irrigation source, in a split plot design, with three replications. Among the different amendment applications, pressmud @ 15 t ha-1 along with 50 % (Gypsum) the soil pH (the reduction of 1.33 % was observed under treated paper mill effluent irrigation and 1.25 % was observed under saline groundwater irrigation), registered low EC, soil organic carbon and available nutrients (N, P, and K) were also improved under poor quality irrigation water. © Society for Sugar Research & Promotion 2009.
