| Abstract/Description: | A field study was conducted on maize (Zea mays L.) crop by using raised bed land configuration and different irrigation techniques for three kharif season (2011 to 2013). The three years kharif seasons pooled results revealed that a significantly superior maize grain yield of 60.0 q ha–1, gross income of Rs 51,136 ha–1, net income of Rs 31,459 ha–1 and B:C ratio of 2.60 was obtained by irrigation level of 0.6 IW/CPE irrigation treatment. A significantly higher water use efficiency of 16.65 kg (ha-mm)–1 was observed with irrigation level at 0.4 IW / CPE and this result also at par with the 0.6 IW / CPE ratio. Planting on 120 cm raised bed treatments. Significantly superior maize grain yield of 60.7 q ha–1, gross income of Rs 52,973 ha–1 and net income of Rs 35,973 ha–1 and B:C ratio of 2.87 recorded. A higher water use efficiency of 15.85 kg (ha-mm)–1 was observed with 120 cm raised bed. The interaction between irrigation 0.6 IW / CPE ratio and 120 cm raised bed configuration treatment recorded a significantly superior grain yield of 66.26 q ha–1, gross income of Rs 52,686 ha–1, net income of Rs 36,314 ha–1 and B:C ratio of 2.65. A higher WUE of 15.47 kg (ha-mm)–1 was recorded with 120 cm raised bed and 0.6 IW / CPE ratio. |
