“…Barley yields generally were lowest on cereal (wheat) stubble and flax yields were lowest on oilseed (canola) stubble, whereas both crops yielded best on pulse stubble. The effect of previous crop on crop yield, which has previously been reported (Wright 1990), was significant for both barley and flax for each site-year. The greater convergence of the response curves of barley on canola stubble and barley on field pea stubble compared with the curves of barley on wheat stubble and barley on field pea stubble (Fig.…”

“…This suggests that the yield difference is due mainly to the improved soil N status following the legume (Baldock et al 1981). However, the yield gap often cannot be closed completely, indicating the involvement of some other factor(s) -the "non-N benefit" (Strong et al 1986;Wright 1990). …”

“…Enhanced seed yield of the cereal crop after the grain legume versus that after a cereal frequently is observed. Wright (1990) determined that in a field pea-barley (Hordeum vulgare L.)-wheat (Triticum aestivum L.) sequence, field pea increased barley yields by 21% and wheat yields by 12% relative to a barley-barley-wheat sequence. Rowland et al (1994) noted a 41% yield advantage of wheat following field pea compared with wheat following wheat.…”

“…Grain legumes can provide a significant yield benefit to a succeeding cereal crop, equivalent to 50-100 kg N ha -1 (Herridge 1986;Wright 1990). The N residual effect of pulses to a succeeding non-legume crop comprises N and non-N benefits.…”

. 1997. Nitrogen contribution of field pea in annual cropping systems. 1. Nitrogen residual effect. Can. J. Plant Sci. 77: 311-322. The nitrogen (N) residual effect of field pea (Pisum sativum L.) to a succeeding non-legume crop was determined in a small plot experiment at Scott, Saskatchewan in the moist Dark Brown soil climatic zone, and in a small plot and landscape experiment near Melfort, Saskatchewan in the moist Black soil climatic zone from 1993 to 1995. The N residual effect, defined as the amount of fertilizer N required for a non-legume crop grown on non-legume stubble to produce the same yield as that of the non-legume grown on field pea stubble, averaged 27 and 12 kg N ha -1 at Melfort and Scott, respectively, in the small plot experiment, and 28 kg N ha -1 in the landscape experiment. Landscape slope position and preseeding tillage did not have a significant or consistent effect on the magnitude of the N residual effect of field pea to the succeeding non-legume crop. The N residual effect, calculated using the difference (economic N rate) method, was presumably due solely to the N benefit, with no non-N benefit contribution. The non-N benefit was effectively marginalized when the crop sequence that included field pea was compared with a reference rotation that included a cereal and an oilseed crop. Based on field pea seed yields and the calculated N residual effect, the N credit (N fertilizer replacement value) of field pea to a succeeding non-legume crop in the moist Black soil climatic zone was 15 kg N ha -1 for every 1000 kg of seed. This is slightly higher than the current recommendation of 5 to 10 kg N ha -1 1000 kg -1 seed. Results from the small plot experiment at Scott indicate that current N credit recommendations for field pea are appropriate for the moist Dark Brown soil climatic zone. Nous avons mesuré l'arrière-effet de l'azote laissé par une culture de pois sec (Pisum sativum L.) sur une culture subséquente non légumineuse. Les emplacements expérimentaux étaient installés à Scott (Saskatchewan) dans la zone pédoclimatique semi-aride des sols bruns foncés en miniparcelles et près de Melfort dans la zone des sols noirs subhumides à la fois en miniparcelles et en parcelles de paysage pleine grandeur. L'effet azotés c.-à-d. la quantité d'engrais N requise par une non-légumineuse pour produire autant après une sole de non-légumineuse qu'après une sole de légumine (pois de grande culture) s'établissait, respectivement, à 27 et à 12 kg N ha -1 à Melfort et à Scott en petites parcelles et à 28 kg dans l'expérience paysagère. L'emplacement sur la pente dans le paysage et la préparation du lit de semence n'avaient pas d'effets significatifs ni réguliers sur l'importance de l'arrière-effet N du pois sur les cultures non-légumineuses suivantes. L'arrière-effet N, calculé par la méthode de la différence (taux de fumure N économiquement rentable) était vraisemblablement dû exclusivement à la présence du N résiduel. Les effets secondaires (autres que celui du N résiduel) étaient effectivement néglig...

“…However, even when wheat prices are high, the risk of economic loss is dramatically incriased in continuous-wheat systems (Zenner et al 1986 (Wright 1990) and other soils (Marcellos 1984;Welty et al 1988) but not for Dark Brown or Brown soils (Townley-Smith lggg; Campbell etal. 1992 Rice et al 1993), but they also use significant amounts of soil water, thereby reducing the amount available to a succeeding crop.…”

Alternatives to summerfallow and subsequent wheat and barley yield on a Dark Brown soil

A number of alternative options to summerfallow are feasible on the Dark Brown soils of the Canadian prairies. These include recropping to cereal or pulse crops, as well as use of summerfallow substitute crops, such as legume green manures. The objective of this study was to evaluate these options for their impact on the productivity of subsequent crops. Green-manure lentil (Lens culinaris Medic.), incorporated at either the bud or full-bloom stage of growth, field pew (Pisum sativum L.), grain lentil, and wheat (Triticum aestivum L.) grown as grain were compared with conventional summerfallow for their impact on yield of a succeeding wheat crop and of barley (Hordeum vulgare L.) grown the year after wheat on a Dark Brown Chernozemic soil at Scott, Saskatchewan. During the 5-yr period, 1984–1988, above-ground dry-matter production of green-manure lentil averaged 500 kg ha−1 at the bud stage of growth but more than doubled to 3170 kg ha−1, by full bloom. Grain yield of field pea averaged 1470 kg ha−1, while that of grain lentil, unfertilized wheat, and N-fertilized wheat averaged 1220, 1290 and 1490 kg ha−1, respectively. Considerable year-to-year yield variation occurred with all crops, variability being greatest for lentil. Yield of wheat grown after lentil green manure was similar to yield of wheat on summerfallow (2340 kg ha−1) during each of the 5 yr for both early (2360 kg ha−1) and late (2250 kg ha−1) incorporation. Wheat yield after pea (2210 kg ha−1) or grain lentil (2080 kg ha−) was reduced in 1987, but it was equal to wheat yield after summerfallow during the remaining 4 yr. Yield of wheat on wheat stubble, whether fertilized with N (1830 kg ha−1) or not (1610 kg ha−1), was generally lower than on summerfallow. Yield of barley grown the following year was generally unaffected by summerfallow or summerfallow substitute treatments. The higher value and similar productivity of pea and grain lentil, compared with wheat, combined with their favourable impact on subsequent wheat yield, should make these crops attractive alternatives to summerfallow. On fields unsuited to pea or grain lentil production, lentil green manures may be a suitable alternative to summerfallow because they should reduce soil degradation, although lentil green manures leave little residue to protect against soil erosion where through incorporation is practised. Summerfallow or green manure incorporated early or late generally resulted in greater available soil water and N for a succeeding crop than did grain lentil, pea or wheat. Key words: Green manuring, legume effect, recropping, lentil, grain yield, summerfallow alternatives

Soil nematode community structure and composition can inform crop managers about soil quality. However, few studies have assessed the nematode community under agricultural systems in cool semi‐arid regions such as the U.S. northern Great Plains. We assessed soil nematode community structure of barley (Hordeum vulgare L.) and barley–pea (Pisum sativum L.) cropping systems from 2016 to 2018 in one tilled and two no‐till field experiments under dryland management in central and southwestern Montana. Soils were sampled prior to planting in the spring and following harvest in late summer and nematodes were classified to genus level via microscopy. Both in season moisture stress and overwinter stress explained decline in nematodes in the central Montana no‐till experiments, although consistent impacts of moisture or overwinter stress on nematodes were not detected in the tilled field experiment. Cropping system or sequence did not impact the nematode population (p > .1), but barley yield was positively correlated with larger nematode populations in both no‐till experiments (r > .60). The percentage of fungivores were negatively correlated (r = –.42) to barley yield under tillage. Plant parasitic nematodes were positively correlated (r = .43) to barley yield under tillage. These results suggest that factors which enhance cereal crop growth and productivity rather than crop diversification drive short‐term nematode community dynamics when crop rotations are established in cool semi‐arid regions. Future work is needed to determine if cropping system changes can impact nematode populations after several years in cool semi‐arid regions and, if so, what ecosystem services result from these transformations.
