YIELD AND QUALITY OF RICE SEEDS PRODUCED UNDER FLOODING CONDITIONS IN DIFERENT WETLAND SOILS

Wetlands, due to their heterogeneous origins, vary significantly in their granulometric and mineralogic composition, which results in different behaviors when under agriculture. The influence of the wetlands in the productivity and seed physiological quality was tested using seeds of irrigated rice, from cultivars Capivari, Sapucai, Urucuia, Inca e MG 1, produced in 94/95 and 95/96, on three different soils: Folic Organosol, Melanic Gleisol, and Haplic Gleisol. All soils are from the Experimental EPAMIG Farm, Cambuquira (MG). The harvested seeds were evaluated using the following parameters: field production, germination (standard test), and vigor, through germination counting and root length. The results showed that the largest production of seeds came from the Haplic Gleisol and the smallest from the Folic Organosol. It was also verified that in all studied soils, the cultivars Urucuia and MG 1 were the most productive. Additionally, it was observed that, in all cultivars, the best seed physiological quality was obtained in the Haplic Gleisol.
