The experiment evaluates the effect of tillage and residue management on wheat performance and related soil, crop and profitability parameters in irrigated conditions in the Yaqui Valley of Mexico. It also assesses nitrogen management in wheat in response to the tillage-residue management treatments.
All treatments have wheat in the winter (main crop) and maize in the summer and are planted on 75 cm beds with furrow irrigation. Main plots have 5 tillage-straw treatments: (1) conventionally tilled beds with residue incorporation, (2) permanent beds with residue burning, (3) permanent beds with only 25 cm of standing wheat stubble retained, (4) permanent beds with retention of wheat and removal of maize residue, (5) permanent beds with retention of all residue. Split plots have 7 nitrogen fertilization treatments that differ in dose (0, 150 or 300 kg N/ha) and timing of N application (pre-plant, at 1st node or split application)
