The agro-ecological conditions of the city of Smederevo, maize yields were studied over a three year period (2013-2015.). A total of 13 corn hybrids (8 hybrids of Maize Research Institute Zemun and 5 hybrids Istitute of Field and Vegetable Crops, Novi Sad). Meteorological conditions, especially temperature, distribution and quantity precipitation the growing season had a significant impact on the yield of hybrids during the three years of research.
The most optimal climatic conditions for the growth of corn were in 2014, and on them were all tested hybrids reacted achieve significantly higher yields (average grain yield in 2014 amounted to 11.83 t ha-1) compared to the other two years (6.40 t ha-1 in 2013, and 5.97 t ha-1 in 2015).
Optimal and adequate agricultural techniques, proper selection of hybrids, proper selection of hybrids for a specific localities, and the application of irrigation it is possible to achieve a stable and high yields of maize and to some extent mitigate the impact of unfavorable meteorological factors, primarily drought.U agroekološkim uslovima grada Smedereva ispitivani su prinosi kukuruza u trogodišnjem periodu (2013-2015. godina). Analizirano je ukupno 13 hibrida kukuruza (8 hibrida Instituta za kukuruz Zemun Polje i 5 hibrida Istituta za ratarstvo i povrtarstvo Novi Sad). Meteorološki uslovi, a posebno temperatura, raspored i količina padavina u toku vegetacionog perioda imale su značajan uticaj na prinos ispitivanih hibrida tokom sve tri godine ispitivanja.
Najoptimalniji klimatski uslovi za uspevanje kukuruza bili su u 2014. godini, a na njih su svi ispitivani hibridi reagovali postizanjem znatno većih prinosa (prosečan prinos zrna kukuruza u 2014. godini iznosio je 11,83 t ha-1) u odnosu na ostale dve godine (6,40 t ha-1 u 2013. godini, odnosno 5,97 t ha-1 u 2015. godini).
Optimalnom i adekvatnom agrotehnikom, pravilnim izborom hibrida za odredjeni lokalitet, kao i primenom navodnjavanja moguće je postići stabilne i visoke prinose kukuruza i donekle ublažiti uticaj nepovoljnih meteoroloških faktora, a pre svega suše
