Scarce water resources severely limit maize (Zea mays L.) cultivation in the temperate
regions of northern Serbia. A two-year field experiment was conducted to investigate the
effects of irrigation and planting density on yield and water use efficiency in temperate
climate under sprinkler irrigation. The experiment included five irrigation treatments (full
irrigated treatment – FIT; 80% FIT, 60% FIT, 40% FIT, and rainfed) and three planting
densities (PD1: 54,900 plants ha
–1
; PD2: 64,900 plants ha
–1
; PD3: 75,200 plants ha
). There
was increase in yield with the irrigation (1.05–80.00%) as compared to the rainfed crop.
Results showed that decreasing irrigation rates resulted in a decrease in yield, crop water use
efficiency (WUE), and irrigation water use efficiency (IWUE). Planting density had
significant effects on yield, WUE, and IWUE which differed in both years. Increasing
planting density gradually increased yield, WUE, and IWUE. For the pooled data, irrigation
...
rate, planting density and their interaction was significant (P < 0.05). The highest two-year
average yield, WUE, and IWUE were found for FIT-PD3 (14,612 kg ha
), rainfed-PD2
(2.764 kg m
–3
), and 60% FIT-PD3 (2.356 kg m
–3
), respectively. The results revealed that
irrigation is necessary for maize cultivation because rainfall is insufficient to meet the crop
water needs. In addition, if water becomes a limiting factor, 80% FIT-PD3 with average yield
loss of 15% would be the best agronomic practices for growing maize with a sprinkler
irrigation system in a temperate climate of Serbia.
