Abstract:

Maize productivity, same as any other crop, is the result of the interaction between all factors involved one way oranother in vegetal production. From 11 maize hybrids considered in the experiments, the highest productions, of over9000 kg/ha, were given, in the pedoclimatic conditions of Dambovi a county, by PR38R92, Clarica and MGM 158714hybrids. The maize grain yield had average values between 81,5% and 85%. EGZ 7403 and X6R223 hybrids had thehighest yield. The most drought-resistant hybrids were Turda 201, Turda Moldova 188 and Clarica and the most heatresistantone was SUM 1093 (SUANITO). The degree of shrivelling was close to 1 for all hybrids, the lowest one beingnoticed for MONALISA, PR38R92 and EGZ 7403. Most of hybrids had a 0% degree of sterility. EGZ 7403 and X6R223hybrids were exceptions, having a 2% and 3% degree of sterility. The hybrids with the highest root strength wereCLARICA, EGZ 7211 and MGM 158714, and those with the highest stalk strength were Clarica, EGZ 7211 andX6R223.
