An experiment was conducted on maize crop (Zea mays L.) in plastic pots in two
different soils (Qurna soil, which is poor organic matter and the other soil from
Maysan marshes, which is rich in organic matter), to study the effect of selenium,
sul
fur and phosphate and their interaction on dry weight of shoot of maize crop.
Selenium was added at four levels (0, 10, 20 and 40 g Se ha), sulfur at three
levels (0, 30 and 60 kg S ha), and phosphorus at three levels (0, 60 and 120 kg P
ha).
