Yields of ZP sweet maize hybrids in dependence on sowing densities

The objective of the present study was to determine the effect of four sowing densities in four ZP sweet maize hybrids of different FAO maturity groups on ear qualitative traits and yields obtained on chernozem soil type in Zemun Polje, Serbia. The observed traits of sweet maize (ear length, kernel row number, number of kernels per row, yield and shelling percentage) significantly varied over years. Generally, it can be stated that sweet maize hybrids of a shorter growing season (FAO 400) could be cultivated up to 70,000 plants/ha, while those of a longer growing season (FAO 500) could be grown up to 60,000 plants/ha. In such a way, the most favourable parameters of yields and the highest yields can be obtained.
