Abstract
The yield and quality of maize, depends of the growing conditions, type of hybrids, as well their adaptation in growing area regarding vegetation period. In this research, have been evaluated the yield and quality of five maize hybrids PKB323, NSSC333, ZPSC704, NS721, NS770, growing in Shtip area.Received results for grain yield, corresponds to other investigations, where hybrids with longer vegetative period (bigger FAO group of maturity), have higher yield. Smallest average grain yield shows the hybrid NSSC 333 (4.05 t/ha), while the largest shows NS 721 (14.05 t/ha). In 2009, average yield of all hybrids was 9.3 t/ha, while in 2010, the total average yield was 9.2 t/ha. Regarding quality properties of the grain, in 2009, PKB 323 shows biggest percentage of total sugars (72.1%), compared with other hybrids. In 2010, it was ZPSC 704 (72.5%). In both years, the biggest protein content was determined in NS 721 (8.9%). The biggest oil content was received in NSSC 333 (3.4%) and PKB 323
(3.6%).
