A field experiment was conducted on the sandy loam soils of CCS Haryana Agricultural University, Hisar, Haryana, India to study the effect of irrigation frequency and salinity levels of irrigation water on yield attributes of cabbage under drip irrigation. The experimental was laid out with two irrigation frequency treatments: daily (F1) and alternate day (F2) irrigation and five salinity levels of irrigation water (canal water ECiw = 0.5 (S1), saline water ECiw = 3.0 (S2), saline water ECiw = 6.0 (S3), saline water ECiw = 9.0 (S4) and saline water ECiw = 12.0 (S5)). In daily irrigation treatment, the relative value of plant height was 104.1, 88.4, 70.7 and 58.2% in F1S2, F1S3, F1S4 and F1S5 treatments, respectively, as compared to canal water irrigation (F1S1). In alternate day irrigation, the relative value of plant height was 105.9, 87.0, 69.4 and 53.1% in F2S2, F2S3, F2S4 and F2S5 treatments, respectively, as compared to the yield recorded in canal irrigation (F2S1). On comparing drip irrigation frequency treatments, 3.2, 2.9, 8.7, 16.1 and 50.2% higher crop yield in daily irrigation as compared to alternate day irrigation of respective treatments (canal water, ECiw 3, 6, 9, 12 dS/m) was observed. This indicates that increase in irrigation frequency can manage saline water in a better way. On comparing drip irrigation frequency treatments, 3.2, 2.9, 8.7, 16.0 and 50.4% higher water use efficiency in daily irrigation as compared to alternate day irrigation of respective treatments (canal water, 3, 6, 9, 12 dS/m) was observed.
