abstract = "Background: Sweet corn (Zea mays L. var. saccharata Sturt.) is an important vegetable plant that, together with peas and green beans, is grown industrially and sold frozen (in grain). Due to the specific processing during which the grain is separated from the cob with knives in the technological phase, the cob must be of the correct shape, completely filled with high-quality grain of uniform maturity, which contributes to the quality and yield of the raw material. In Serbia, sweet corn intended for industry is grown in two sowing periods, regular (spring) and late (summer) with mandatory irrigation. The aim of this work was to examine the possibility of growing sweet corn in the agro-ecological conditions of central Serbia (Velika Plana). Materials and Methods: During 2022 and 2023, the currently most popular sweet corn hybrid 'Enterprise' was tested. In both examined years, sowing was done at the beginning of May and July, and sweet corn was grown at a density of 65,000 plants ha-1 (70x22 cm). Tapes with a capacity of 10 lit•H2O•m-1•h were used for drip irrigation. Two irrigation norms (full and reduced 50%) and the regime of natural wetting conditions were applied as a control treatment. In both years of testing, the experiment was set up at the beginning of May and July by sowing the most popular sweet corn hybrid Enterprise F1 in our area. Harvesting and analysis of cobs was done on average 24 days after fertilization. Results: The dates did not have a significant effect on the length of the cob and it was 21 cm on average for both sowing dates. Treatments with watering had a length of cobs significantly greater than the control, while their values were not statistically significantly different. The diameter of the cob was on average 4.89 cm and it was significantly influenced by the time of sowing and the irrigation regime. The total mass of the cob differed significantly according to the dates and had values of 279.4 g for the May sowing, and 306.2 g for the second sowing date. In the variant without irrigation, the value for the weight of the piston was 224.5 g, which is significantly lower than the value from the treatment with watering. The weights of the pistons at reduced and full watering rates did not differ statistically significantly. The grain mass parameter behaved in an identical way, which was 196.6 g on average for all treatments. Conclusion: Taking everything into account, it can be concluded that sweet corn can be successfully grown in Serbian field conditions in both sowing periods, but that the quality of the yield is better with later sowing (later production). Excellent results are achieved by using the drip system for irrigation and at a reduced rate of irrigation.",
