Abstract

Khakbazan, M., Grant, C. A., Irvine, R. B., Mohr, R. M., McLaren, D. L. and Monreal, M. 2009. Influence of alternative management methods on the economics of flax production in the Black Soil Zone. Can. J. Plant Sci. 89: 903-913. Studies were conducted at two locations on two Orthic Black Chernozemic soils over 4 yr to evaluate the economic effects of tillage system, preceding crop, phosphorus (P) fertilization of the preceding crop, and P fertilizer application on flax (Linum usitatissimum L.) production. Canola (Brassica napus L.), a non-mycorrhizal crop, and spring wheat (Triticum aestivum L.), a mycorrhizal crop, were grown as the preceding crops under conventional (CT) and reduced tillage (RT) systems, with 0, 11 and 22 kg P ha -1 applied as monoammonium phosphate (MAP). The following year, flax was planted with application of 0 or 11 kg P ha -1 as MAPside-banded at seeding. Tillage method had no impact on the net revenue of wheat or canola at either location when averaged over the 2 yr of study. Net revenue of flax was higher ($32 ha-11 to $95 ha-11) when preceded by wheat compared to can regardless of tillage system or location. Net revenue averaged across the complete crop sequences was higher ($36 ha -11 to $62 ha-11) under RT than CT. Lower net revenue variability was also associated with use of RT management, and when wheat was the preceding crop. Changes in commodity prices and input costs had little effect on the relative rankings of the treatments. Flax production with wheat as a preceding crop together with RT and lesser use of Papplication was the most economical treatment under current input and output prices.
