SummaryUpland rice (Agbede) and swamp rice (BG 79) varieties grown on flooded soil, and on soil maintained at 80 and 100% moisture saturation were sprayed with solutions containing 0 ppm (MO), 10 ppm (Ml), and 20 ppm (M2) of manganese.The M 2 treatment depressed total dry weight and dry weights of leaf laminae, stems, leaf sheaths and root of both varieties grown on soil maintained at either 80 or 100% moisture saturation. The M 1 treatment increased the ear weight of Agbede grown on soil maintained at either 80 or 100% moisture saturation, while the M 2 treatment increased the ear weight of plant grown on saturated soil. In flooded soil both the M 1 and M 2 treatments significantly increased dry weight of Agbede plants, but only the M 2 treatment increased ear dry weight of BG 79. The ear weight of Agbede plants receiving M 0 and M 1 treatment decreased with increasing soil moisture while that of BG 79 increased.It is considered that manganese supply limits yield of Agbede grain grown on flooded soil.
