Aseptic culture and survival rate at the initiation of in vitro culture of soybean callus, cv Felix, on Murashige and Skoog 1962 culture medium with 0.1 mg/L 6-Benzylaminopurine + 0.1 mg/L Thidiazuron. S1—conventional soil system: plow + seedbed preparation with rotary harrow + seeding + fertilizer, no herbicide. S2—conventional soil system: plow + seedbed preparation with rotary harrow + seeding + fertilizer + S-metolachlor 960 g/L, imazamox 40 g/L and propaquizafop 100 g/L, with 1.5 L/ha, 0.8 L/ha and 1.5 L/ha. S3—conventional soil system: plow + seedbed preparation with rotary harrow + seeding + fertilizer + dimethenamid 720 g/L, bentazone 480 g/L and fluazifop-P-butyl 150 g/L, with 1.2 L/ha, 2.5 L/ha, and 1.5 L/ha. The values shown are means ± S.E (standard error). Different letters above the bars indicate significant differences according to Tukey’s HSD test (p ˂ 0.05).
