“…Net returns were computed and presented as annual values and as 18-yr mean values for the periods 1967(previously analyzed, Zentner and Campbell 1988. Riskiness of each cropping system was assessed using stochastic dominance analysis (Goh et al 1989) to compare the probability distributions of net returns for groups of producers having low, medium, and high risk aversion as defined by Zentner et al (1992). All purchased inputs and machine operations were valued and held constant at their 2003 cost levels (Table 2) Premium rates (at the base cost level) and payout criteria for Risk Area #10 of Saskatchewan were assumed (Table 2) (Saskatchewan Crop Insurance Corporation 2003).…”

Producers in the semiarid Brown soil zone of the Canadian Prairies have historically used fallow (F)-based cropping systems with mechanical tillage methods to produce spring wheat (Triticum aestivum L.) (W). However, in the past two decades government policies and programs have changed, as have cropping practices, market opportunities, and weather patterns. This study re-examines the economic merits of these conventional cropping systems under today’s conditions in regard to the optimal cropping frequency, value of applying N and P fertilizer at soil test rates, and the possible advantage of replacing monoculture wheat with lentil (Lens culinaris Medikus) (Lent) or flax (Linum usitatissimum L.) (Flx) grown in mixed rotations. The analysis draws on data from a long-term crop rotation experiment that was established in 1967 on an Orthic Brown Chernozem at the Semiarid Prairie Agricultural Research Centre at Swift Current, Saskatchewan. All cropping systems were managed using conventional tillage practices, which attempted to conserve as much surface crop residue as possible (i.e., stubble mulch tillage techniques were used). The findings for 1985–2002, a period characterized by above normal precipitation, were compared with those reported previously for the 1967–1984 period when growing conditions were less favorable but more typical for this area. Net returns during 1985–2002 were highest for W-Lent ($93 ha-1 yr-1) and lowest for F-Flx-W ($38 ha-1 yr-1). Net returns for well-fertilized F-W, F-W-W, F-W-W-W-W-W, and Cont W during this same period were similar, averaging about $52 ha-1 yr-1 or 44% less than for W-Lent. These results contrast with those reported for the previous 18-yr period when F-W and F- W-W generally produced higher net returns than Cont W. Within the F-W-W systems, the application of both N and P fertilizer increased the 18-yr (1985–2002) mean net returns by $18 ha-1 yr-1 compared with application of N only, and by $32 ha-1 yr-1 compared with application of P only. For Cont W the application of N and P fertilizer increased the mean net returns by $71 ha-1 yr-1 compared with application of P only. These economic benefits from N and P fertilization were much higher than those reported in 1967–1984 due to the more humid growing conditions and the increased rate of N fertilizer prescribed by the soil testing lab since 1991. Further, our findings showed that only if producers were highly risk averse, do not subscribe to all-risk crop insurance , or if the price for wheat was high or price for lentil low, would the monoculture wheat systems be preferred to W-Lent. However, producers who are highly risk averse would still opt for the cropping systems that included some summerfallow. Our findings support the recent trends in land use practices by area producers towards more diversified and intensive cropping systems which are less reliant on frequent fallowing.

Economics of monoculture cereal and mixed oilseed-cereal rotations in west-central saskatchewan. can. J. plant Sci. 76: 393-400. The effects ofproduct price and input cost on the economic performance and riskiness of nine cropping systems were assessed over a 12-yr period on a Dark Brown Chernozemic loam to clay loam soil at Scort, Saskatchewan. mJrotations included two 2-yr fallow (F)-crop systems with hard red spring wheat-(W) (Triticum aestivum L.) and canola (c) (Brassica campestris L ), four 3-yr fallow-containing rotations with combinations of wheat, canola, and barley 181 lHordeum irigor" L.), a a-yi and a 6-yr rotation that included alfalfa (Medicago sativa L') hay' and continuous wheat. All crops were fertiliied with rates of N and i, based on general guidelines for the region, except for forage hay which was unfertilized. Four rotations (F-C, F-C-W, F-C-B, and F-W-W) showed good economic,a1^O rlst performance under most price scenarios. The F-w and F-w-B rotations generally ranked intermediate, averaging about llTo lower in net return than the best systems at 1994 commodity price levels; however,-at grain prices lower than 75% of these values, net returns were highest with F-W and F-C. It was profiLble to substitute canola foiwheat grown on fallow when the ratio of canola price to ryleat p^ri-c^e exceeded l.g, and to substitute barley for wheat grown on stubble whin the barley/wheat price ratio exceeded 0.75. Including alfalfa hay in the rotation was profitable only when thi haylwheat price ratio^exc_eeded 0.8. The unit cost of producing wheat averaged idS'1 i' ;tr.r trown on i"ii"*, S r OO tjl when grown on canola stubble, $ I 16 rl when grown on wheat stubble in fallow-containing i"tutl""r, u"o"slriii.n.n grown on contin-uous wheat stubble.
