Abstract: A field experiment was conducted during 2015-16 and 2016-17 to compare the paired row technique and normal drip irrigation system on brinjal in Vertisols of Malaprabha command in Northern Karnataka. Drip system with irrigation treatment as 1.0 Etc, 0.8 ETc and 0.6 ETc in the paired row technique and normal drip system were considered along with farmers method as check was considered for the study. Normal row (22.74 T.ha^-1) and paired row drip system yields (21.16 T.ha^-1) brinjal which is on par with farmers method (19.15 T.ha^-1). The water use efficiency was maximum 41.17 Kg. (ha.mm)^-1 with paired layout and with farmers method was recored 41.4 Kg. (ha.mm)^-1 but also which is on par with normal drip system method of irrigation 38.7 Kg. (ha.mm)^-1. The gross and net income was recorded maximum (Rs 186080 ha^-1 and Rs 86250 ha^-1) in normal drip system and also this was on par with the paired row and farmers method of irrigation. The B:C ratio was maximum (2.07) in case of normal system which was recorded non-significant with the other treatments. The superior water use efficiency was recorded with 0.6 ETc (46.51 Kg. (ha.mm)^-1). Interaction effect between irrigation 0.8 ETc with normal row drip system was also recorded superior water use efficiency (46.51 Kg. (ha.mm)^-1. The overall water saving was recorded about 12.89 percent, 22.31 percent and 42.34 percent with 1.0 ETc 0.8 ETc, and 0.6 ETc respectively compared with farmers method.
