Solid soybean seeding OK with reduced tillage ST. LOUIS - It looks like con servation tillage is compatible with solid seeded soybeans, ac cording to agronomists at Purdue University. “The normal yield response we’ve come to expect from solid seeding is coming through with conservation tillage systems,” says Marvin Swearingin. Swearingin and his associate Donald Griffith recently com pleted a year’s study of solid seeded soybeans and conservation tillage. The study was in corporated into two ongoing corn soybean tillage rotation ex periments at the Purdue Agronomy Farm (PAF) at Lafayette and the Southeastern Purdue Agricultural Center OSEPAC) at Butlerville. “Although we have just one year’s information, I think no-till drilled beans will work if a specially adapted drill is used and perennial weeds are not a problem,” Griffith says. “Equipment manufacturers have come out with new drills recently that will work with conservation tillage and fanners are eager to put them to use.” The agronomists say their first year results came closer to meeting their objectives than they had anticipated. In thin part of their research, which was funded by the American Soybean Association and BASF Wyandotte, the researchers wanted to com pare the effect of crop rotation, tillage system, and row spacing on soybean seed yield and other plant characteristics. They also wanted to see what the odds were for season-long weed control in soybeans planted in untilled seedbeds using only post emergence as opposed to pre TRI-COUNTY SWINE SYSTEMS ‘"When It’s Time To Build.

Tillage systems used at the main tillage plots at PAF were fall plow, fall chisel, till-plant, and no-till both following com and as con tinuous soybeans. The main tillage plots at SEPAC were spring plow, spring chisel, spring disc, fall formed beds, and no-till, all after com. The researchers split the plots so that they could compare 10-inch rows and 30-inch rows, except on the tilt-plant and bed systems, which aren’t suitable for solid seeding. The plots were also split to compare pre- and post emergence herbicides. The agronomists were able to produce no-till soybean yields at the two locations equal to yields with conventional tillage. Under no-till, the soybean plants were slightly shorter, lodged slightly less and had more weeds, but not enough to affect seed yield, the researchers say. “All the no-till plots were treated with Paraquat at planting for knock-down of growing weeds,” Griffith says. “We did not have a problem in getting a stand of no-till beans, but extra weight must be added to the drill for dense soils.” Problems of full-season no-till soybean production are not all resolved. “Consistent and economical weed control will depend on weed species present and timely post-emergence her bicide application,” according to Griffith. “I'd still go for the combination of pre-emergence and post-emergence herbicides in many situations. With double cropping, however, no-till solid seeding has been very successful with pre-emergence chemicals.” Row spacing showed the largest and most consistent effect in the r_ HEATING PADS The Proven Plan to Increase Your Hog Confinement Profits.

Drilled plots averaged 53.2 bushels per acre across all tillage, herbicide and rotation combinations, an increase of 7.3 bushels or 16 percent over 30- inch rows. Weed control in solid stands was equal to 30-inch rows and in some cases better where solid drilled soybeans were more competitive with weeds than noncultivated rows. “The most difficult environment for weed control is, obviously, no till continuous soybeans in rows,” Swearingin says. “In a true no tillage situation, drilled soybeans offer their greatest advantage over rows.” Similar trends were observed at SEPAC. In spite of the fact that the no-till plots had slightly more weeds, the highest yields - close to 60 bushels per acre - were ob tained in the no-till drilled plots. This suggests that if weeds can be consistently controlled, excellent soybean yields are possible on the flat, poorly-drained problem soils of southeastern Indiana.
