A field experiment was conducted during 2012 and 2013 with three maize hybrids viz, 30V92, Sandhya and
DHM-117 treated with five levels of irrigation waters viz., BAW (Best Available Water), E 2, 4, 6 and 8 dS
iw m-1 through drip irrigation in Factorial Randomized block design with three replications. The soil physico
-1 chemical properties and nutrient contents were also studied to know the impact of saline irrigation. Considerable
variations were found in soil properties. Soil pH decreased with increased EC
levels while soil ECe values

increased. Soil NPK contents were slightly varied with higher EC levels due to non-availability of water.
Significant yield reductions were noticed in all the three maize hybrids with each increment in salinity of
irrigation water. Among three hybrids 30V92 hybrid got the highest yield (55.5 qha-1) followed by Sandhya and
DHM -117. Highest K/Na ratio was found in 30V92 hybrid revealing that, it is the significant character for
tolerant to salinity levels as compared to other hybrids
