Abstract: An experiment was conducted at PunjabrnAgricultural University, Ludhiana, Punjab in the year 2010 to study the effectrnof various sowing methods, mulch levels and irrigation regimes on growth andrnyield of August sown maize. The field experiment was laid out in split-plotrndesign with 18 treatments combinations, six combinations from method of sowingrn(flat, ridge  and bed) and mulch ( nornmulch and mulch @ 6t ha^-1)  as main plot treatments and three irrigationrnlevels as sub plot treatments (irrigation at IW/CPE ratio 0.50, 0.75 and 1.00).rnThe data indicated that grain yield for bed planting (78.2q ha^-1)  was significantly higher than ridge (74.8q ha^-1)rnand flat (70.6q ha^-1) . Mulch application hadrnno significant effect on various yield attributing character and yield itself.rnSignificantly higher yield was recorded under irrigation regime I_1.00rn(80.3q ha^-1)  as compared to I_0.75rn(75.9q ha^-1) and I_0.50rn(67.4 q ha^-1). The data also revealedrnthat for yield attributes such as total cobs ha^-1,rngreen cob yield (q ha^-1), stover yield (q ha^-1)  and harvest index etc., higher numeric valuesrnwere recorded under bed planting and irrigation regime I_1.00rnas compared to other sowing methods and irrigation regimes.
