| Abstract | The soybean crop is an important and growing in several areas in Brazil. To ascertain the influence of water content on seed germination of soybean (Glycine max (L.) Merrill). An experiment was done to see if the water day after sowing would interfere with the germination, applying a layer of 5 mm at different times: 1, 2 or 3 days after sowing. Blades were applied 1, 2, 3, 4, 10, 25, 30 and 35 mm in soil, on the day of sowing, irrigation and a further 5 mm of water on the 4th day after sowing in all treatments. The tests were tested in the Oxisol, medium texture, and it was evaluated the percentage of emergency and normal seedlings (force) in two periods (6th and 11th days after sowing). The cultivar used was NK7074RR obtained harvest 08/09. 300 seeds were sown at 2 cm depth, totaling three replicates of 100 seeds per tray of 0.118 m2, in a randomized design. Irrigation of 5 mm in the first or second day after sowing are sufficient to obtain an emergency around 85.92%, down 31.09% the percentage of emergency where such watering is done on the third day. Regarding the addition of different levels of water depths in the soil at sowing day, the prediction equations showed that the water depth of 9.2 mm makes it possible to obtain higher values of emergence and vigor under the conditions of this experiment. |
