In agro-ecological conditions of hill-mountainous regions in the Valjevo (place Planica, near Mionica) altitute 670 m on acid-gray brown forest soil there were investigated early ZP maize hybrids FAO group 100-200 for sum of effective temperature on growing season. In investigation were included 18 ZP hydrids - 9 ZP hybrids from Zea mays L. var. indentata and 9 ZP hybrids from Zea mays L. var. indurate. Growing season is on 103 days (ZP 105) to 110 days (ZP 196), and 109 days (ZP 243) to 114 days (ZP 304). Sum of effective temperature of growing season was 950 deg C (ZP 105) to 1102 deg C (ZP 304). The region of growing season is early ZP hybrids on altitute 700-1000 m.
