Interpretive Summary:

Technical Abstract: Effect of tillage (moldboard, plow, ridge till, permanent beds and no-till) on yield and leaf tissue nutrient contents at initial flowering stage of growth were compared for drained (within 4.5 m of the drain) and undrained (22.5 to 31.5 m from the drain) conditions. Corn grain yield decreased with increasing distance from the drain. Average yield was 7.8 Mg/ha within 4.5 m, 7.1 Mg/ha at 9 m, 6.3 Mg/ha at 18 m, and 6.0 Mg/ha at 27 m distance from the drain. Soybean grain yield was not affected by distance from the drain. Tillage method had no effect on grain yield of corn, but soybean was 8.5% lower in beds and no-till compared with ridge till and plow till. The Ca, Mg and B content of corn leaf tissue was significantly greater with moldboard plow and ridge till than with no-till and beds. Mn content of corn leaf tissue was significantly greater with beds and no-till than with moldboard plow and ridges. Subsurface drainage significantly increased Mg, Mn, Zn and Na contents of corn leaf tissue compared to undrained. The N content in soybean leaf tissue was significantly greater with no-till than with ridges and beds. The Ca content of soybean leaves was significantly greater with no-till and beds than with moldboard plow. The Mn content in soybean leaf tissue was significantly lower with moldboard plow than with beds, and A1 content was less with no-till than with ridges. Subsurface drainage significantly increased Cu content of soybean leaf tissue and decreased Fe content compared to undrained.
