The aim of this investigation was to estimate the effects of total early rainfall and total rainfall during anthesis - silking interval (ASI) on grain yield and grain moisture in nine hybrids of maize. Studied hybrids belong to different maturity groups: FAO 400 (ZP 42A, ZP 434, ZP 480), FAO 500 (ZP 570, ZP 580, ZP 599) and FAO 600 (ZP 677, ZP 680, ZP 684). Field trial were carried out in dry land farming, at location Bjeljina, during 2002 and 2003. Two years differed significantly in amount and distribution of precipitation. In 2003, average grain yield for hybrids, was significantly higher then in 2002 because of better precipitation and higher amount of precipitation during ASI. In both research years, hydrids within maturity group FAO 600 produced higher grain yield (10,792 kg/ha) then hybrids within maturity FAO group 500 (9,545 kg/ha) and FAO 400 (8,725 kg/ha). It was concluded that the total amount of rainfall is not as significant for grain yield of maize, as the amount of rainfall during ASI.
