Deep and shallow fall tillage for irrigated soybean grown with different weed management systems in the midsouthern USA

Management inputs that maximize economic return from early soybean Glycine max (L.) Merr. production system (ESPS) plantings in the midsouthern USA have not been evaluated fully. The objective was to determine the effect of different weed management systems on yield and net return from irrigated ESPS plantings of soybean following deep (DT; 40-45 cm deep) and shallow (ST;
