Abstract

Different deficit irrigation management scenarios as alternate FURROW IRRIGATION with regard to sensitive growth stages of CORN were assessed in terms of the effects on YIELD and YIELD components. The research was performed as a randomized full block design with six treatments and three replications. The treatments were comprised of: full FURROW IRRIGATION within whole growing season, alternate FURROW IRRIGATION in whole growing season, full irrigation at the establishment stage and alternate irrigation at the other stages, full irrigation at flowering stage while alternate irrigation at the other stages, full irrigation at establishment and flowering stage accompanied by alternate irrigation at the other stages, full irrigation at flowering and ripening stages and alternate irrigation in other stages. Overall, the effect of deficit irrigation on YIELD and YIELD components was statistically significant (p<0.01). Full irrigation in the whole growing season led to the highest wet forage YIELD (67022 kg/ha) and while alternate FURROW IRRIGATION in the whole growing season, the lowest wet forage YIELD (50064 kg/ha). The most desirable treatment was recorded as: full irrigation at the flowering stage and alternate irrigation in the other stages. With this treatment, the reduction in wet and dry forage YIELDs, leaves wet and dry weights as well as stem wet and dry weights in comparison with control were about 8 to 14 %. This is quiet acceptable as it saves 39% irrigation water. The highest irrigation WATER USE EFFICIENCY (1.88 kg/m3) was achieved through full irrigation at flowering stage with alternate irrigation of the other stages.
