“…For instance, in the semi-arid region of Canada, the prevalence of fallow has decreased from 50 to 15% since the 1970s, coinciding with the development of chemical weed management and the adoption of direct seeding practices (Zentner et al, 2002a). The intensification of crop rotations enabled the expansion of pulse crops in semi-arid Canada (McVicar et al, 2000), which performed well in water-stressed environments of the Canadian prairies dominated by summer rainfall (Angadi et al, 2008;Cutforth et al, 2009;Bueckert and Clarke, 2013). Furthermore, the shallower rooting depth of pulse crops compared to cereals left behind deep residual water to support subsequent cereal and oilseed crops (Gan et al, 2009).…”

Ecological instability and low resource use efficiencies are concerns for the long-term productivity of conventional cereal monoculture systems, particularly those threatened by projected climate change. Crop intensification, diversification, reduced tillage, and variable N management are among strategies proposed to mitigate and adapt to climate shifts in the inland Pacific Northwest (iPNW). Our objectives were to assess these strategies across iPNW agroecological zones and time for their impacts on (1) winter wheat (WW) (Triticum aestivum L.) productivity, (2) crop sequence productivity, and (3) N fertilizer use efficiency. Region-wide analysis indicated that WW yields increased with increasing annual precipitation, prior to maximizing at 520 mm yr −1 and subsequently declining when annual precipitation was not adjusted for available soil water holding capacity. While fallow periods were effective at mitigating low nitrogen (N) fertilization efficiencies under low precipitation, efficiencies declined as annual precipitation exceeded 500 mm yr −1 . Variability in the response of WW yields to annual precipitation and N fertilization among locations and within sites supports precision N management implementation across the region. In years receiving <350 mm precipitation yr −1 , WW yields declined when preceded by crops rather than summer fallow. Nevertheless, WW yields were greater when preceded by pulses and oilseeds rather than wheat across a range of yield potentials, and when under conservation tillage practices at low yield potentials. Despite the yield penalty associated with eliminating fallow prior to WW, cropping system level productivity was not affected by intensification, diversification, or conservation tillage. However, increased fertilizer N inputs, lower fertilizer N use efficiencies, and more yield variance may offset and limit the economic feasibility of intensified and diversified cropping systems.

Managing Harvest Time to Control Pod Shattering in Oilseed Camelina

Camelina (Camelina sativa L. Crantz) is an oilseed crop with the potential for dryland crop production in the Great Plains. However, pod shattering may cause signifi cant yield losses. We determined the impact of diff erent harvest times on camelina seed yield (SY), water use effi ciency, protein and oil content, and estimated biodiesel yield. Spring (Blaine Creek) and winter (BX WG1) camelina cultivars were harvested at three diff erent stages, corresponding to the three-digit Biologische Bundesanstalt, Bundessortenamt und Chemische Industrie (BBCH) scales of 805 (early harvest; 50% ripe pods), 807 to 808 (midharvest; 70-80% ripe pods), and 809 (late harvest; >90% ripe pods). In addition, diff erent harvest methods were assessed to identify and quantify other sources of yield loss. Seed moisture contents at early, mid, and late harvests were 14.2, 9.8, and 6.8%, respectively. On average, the SY of early harvest was 9.5 and 23.6% greater than the mid-and late harvests, respectively. Total seed loss incurred during direct-combine harvest was 11.7%, which was attributable to the mechanical disturbance imposed on the pods and the combine settings. Camelina seed oil content was greatest at mid-harvest, but the estimated biodiesel yield was not signifi cantly diff erent between the early and mid-harvests. In general, direct combining when 75% of camelina pods are ripe will provide a balance between SY loss and the seed protein and oil contents.

. 2009. Comparing plant water relations for wheat with alternative pulse and oilseed crops grown in the semiarid Canadian prairie. Can. J. Plant Sci. 89: 823Á835. Understanding the drought physiology of alternate crops is essential to assess the production risks of new cropping systems. We compared the water relations of dry (field) pea (Pisum sativum L.), chickpea (Cicer arietinum L.), canola (Brassica napus L.) and mustard (Brassica juncea L.) with spring wheat (Triticum aestivum L.) under different moisture availabilities in field trials conducted in 1997 and 1998 at Swift Current, SK. Stress experience and stress responses varied with crop type. In general, there were similarities in drought physiology between the two pulse crops and between the two oilseed crops. The mean predawn leaf water potential of pea was frequently lowest, while the mean midday leaf water potential of wheat was at least Á0.40 MPa lower than for any other crop. The crops exhibited different strategies to overcome water stress. Wheat had the lowest osmotic potential at full turgor, except under drought when turgor was lowest for chickpea and wheat; the highest values were observed in Brassica spp. Mean midday pressure potentials were lowest in wheat (and mostly negative, indicating loss of turgor) and highest for the pulse crops. Mean midday pressure potential for canola was positive when well-watered, otherwise it was near 0. Despite lowering osmotic potential, wheat could not maintain positive turgor much of the time at midday. Pulse crops, with the contributions from both osmotic adjustment and cell elasticity, maintained positive turgor over a wider range of water potentials compared with the other crops. With regard to both osmotic adjustment and tissue elasticity, we ranked the crops from high to low ability to adjust to moderate to severe water stress as pulses wheat Brassica oilseeds.Key words: Leaf water, osmotic, turgor potentials, wheat, pulse, canola, semiarid prairie Cutforth, H.
