Maize hybrids productivity under different spatial arrangement
The more favourable sowing pattern provided by closer rows enhances a maize growth rate that led to a higher radiation use efficiency and a greater grain yield. The three maize hybrids of different maturity groups were grown in three spatial arrangements with and without herbicide application, during 2005-06 at Zemun Polje, Belgrade, Serbia. The aim was to estimate if the diferent spati al arrangements of maize plants in a combination with the herbicide application influenced the hybrids height, aboveground biomass productivity and the grain yield. The highest plant height, as well as, the aboveground biomass productivity, on the average for all observed hybrids, were achieved in the spatial arrangement of the inter-row distance of 50 cm x the distance between the plants in the row of 35 cm (SP2). The grain yield of studied maize hybrids did not significantly differ over spatial arrangements during the years of investigation. Recently developed hybrids better respond to changes in spatial arrangements of plants. The higher values of the plant height, productivity and the grain yield of studied hybrids were recorded when herbicides were applied in the recommended rate and half the recommended rate than in the untreated control. Growing maize hybrids in the adequate plant pattern and with the application of herbicides at lower rates provides the advantage to the crop over weeds with the simultaneous environmental protection.
