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.
