On-row seeding enhanced P and K concentrations of wheat plants at early growth stages up to flowering, relative to between-row seeding, when the respective soil-test P and K concentrations were low and/or when MAP fertiliser was not banded at seeding... Mean wheat yields (i.e. average of 2 or 3 MAP fertiliser rates ranging from 0 to 50 or 80 kg ha -1) were: (a) 11-14 per cent lower with on-row seeding at Binnu (where wheat followed wheat in 25 cm rows); (b) 7 per cent higher with on-row seeding at Mullewa (where wheat followed barley in 30 cm rows); and (c) not different at Pindar (where wheat followed wheat in 30 cm rows)... Project No.: 67F Central Farming Systems Paper reviewed by: Linda Leonard Crop Updates is a partnership between the Department of Agriculture, Western Australia and the Grains Research & Development Corporation 73..
