Abstract
Zinc deficiency has been observed at the early growth stage of seed-maize crops grown on neutral to slightly alkaline calcareous soil of the Eastern Croatia.. Maize chlorosis were in close connection with the higher soil pH and the higher extractable Zn status. Ten maize inbred lines were grown on Đakovo slightly alkaline and drained gleysol (the soil A) in the growing season 1995 and on Osijek neutral eutric cambisol (the soil B) in the growing season 1996. The trials were established in four replications. Two rows of each genotype were treated with the solution of zinc sulfate (0.75% ZnSO4.7H2O), while remaining two were a control. The first treatment of spraying was at the beginning of June and the second treatment following ten days. Maize genotypes response to foliar spraying with 0.75% ZnSO4.7H2O solution was less expressed in the first year of testing: average grain yields were similar (2890 kg/ha and 2992 kg/ha, for control and spraying, respectively) while only two genotypes responded by yield increases (17% and 13% higher yields by the Os84-49 and by the Os84-24, respectively). However, in the second year of testing average grain yields were 4078 kg/ha (control) and 4418 kg/ha (spraying): by five genotypes (Os84-24, Os84-49, Os84-28, Os64-9 and Os86-39) grain yields increased from 11% to 18% as affected by ZnSO4.7H2O application.
