Water quality and soil compaction are the two important parameters that influences the normal infiltration rate for the applied water or rainfall. The infiltration rate of water into soil varies widely and can be greatly influenced by the quality of the irrigation water and degree of compaction. This experiment was carried out to know the impact of these two factors on sandy loam and clay soil. To obtain the representative values, a total of 96 locations were identified covering all the plots to measure the infiltration characteristics of the soils in no tillage condition and later in primary tillage condition. In each plot two sample readings were taken with different irrigation quality water such as fresh water, 2 EC, 4 EC, 6 EC etc. The infiltration rate is found to be varying from 0.21 to 0.31 cm/hr in combine harvested field and varying from 0.78 to 3.80 cm/hr in No combine harvested field after the application of tillage. This shows the variation of infiltration rate is more in sandy loam soil when compared with clay soil.
