Abstract

In the period of three years, there have been established investigations, about influence of water deficit on the yield elements of maize. The research has been performed in eight hybrids of maize, which belong to four FAO groups. From the results, we can note increasing of the values of structure elements of yield, in all investigated maize hybrids. Under drought influence, the number of ear per plant was decreasing for 27,6 %, ears length for 17,5 %, diameter of ear for 20,2 %, seed length for 23,2 %, and number of rows per ear for 12,6 %.
