Author(s): Bethelhem Awoke Sheferia*, Mequanint Birhan Alem and Awel Seid
The declining availability of fresh water has become a worldwide problem, which maintains the development of alternative, secondary quality water resources for agricultural use. In this study, the effects of different irrigation intervals at different salinity levels of irrigation water impacts on soil physico-chemical properties were investigated using three irrigation intervals (I1 =3days, I2= 4days and I3= 5 days) with four salinity levels (S1= 4dS m-1, 5dS m-1 and 6 dS m-1) in a factorial combination using CRD with three replications. Statistical analysis showed that salinity, irrigation interval and their interaction highly significance effects (p<0.001) on electrical conductivity of soil. Irrigation with highest salinity level (S4) with five days of irrigation interval resulted in the salt.. View More»
