SUMMARY
Crop production systems in the southwestern North Dakota are almost exclusively limited to small grains. Average yields for these crops sometimes are lower than those required to return an adequate profit margin to producers, if government price supports are not considered. Even when government payments are made, in some instances small grain crops cannot profitably be grown in most years.
Expanding cropping choices has been suggested as a possible strategy for profitable crop production (Jolliff, 1989). Crop diversity also can expand market opportunities, improve pest control, and enhance soil conservation (Jolliff and Snapp, 1988). In North Dakota, development of crambe points to the benefits which biological diversity in cropping systems can offer. Crambe is naturally resistant to many pests and can be used to break small grain disease cycles in rotations (Endres and Schatz, 1991). The seed oil is highly-valued by the chemical industry (Van Dyne et al., 1990), opening up new markets to primarily food and feed producers. Crambe also produces considerable amounts of residue and can be managed to protect cultivated fields from wind and water erosion.
Successful production of alternative crops in southwestern North Dakota would provide many benefits to producers. Crambe and other industrial crops could be grown and sold as high-value industrial feedstocks. Pulses like field pea can be intercropped with cereal feed grains to enhance protein content of annual forages (Carr and Martin., 1996). Field pea also can be grown alone as high-protein feed grains as well as soil-enhancing crops. This project is directed at evaluating several alternative crops in southwestern North Dakota. This project will collect and publish information on the performance of cereal forage crops and alternative crops and crop management strategies in southwestern North Dakota.
OBJECTIVES
INTRODUCTION
Corn is an important annual forage in southwestern North Dakota. According to Beard and Hamlin (1996), corn was planted on approximately 800,000 acres of cropland in 1994; this is approximately the same amount of acreage that was devoted to oat production. The importance of corn in the region supports adaptation trials of newly developed hybrids. These trials should reflect changes in corn production strategy, including increased planting rates and narrower row spacing.
Conlon and Douglas (1957) reported that corn produced larger yields per acre than any other feed crop grown at the Dickinson Research Extension Center between 1907-57. In summarizing earlier research, Conlon and Douglas (1953) concluded that a corn-wheat-oat rotation generated considerably greater returns than a fallow-wheat-oat rotation on diversified crop-livestock farm operations. The corn produced on the farm was marketed through livestock.
Corn grown as silage is an excellent forage crop. However, soybean meal generally is added to correct protein deficiencies (Goodrich and Meiske, 1976). The soybean meal added to the feed ration is an off-farm cost to producers in southwestern North Dakota, since soybean is not adapted to local growing conditions and little is grown (Beard and Hamlin, 1996). Adaptation screening trials suggest that pea may successfully be grown in western North Dakota (Eriksmoen et al., 1995). However, much must still be learned on how to best grow pea in the dryland environment of western North Dakota. If successful pea production practices can be developed, then pea might be grown and used as a high protein supplement in selected livestock rations.
An alternative to growing corn for silage is to grow other cereals like barley or oat as haylage. While past work indicates that both these crops produce less total digestible nutrients than corn grown for either grain or silage (Smith and Stoa, 1944; Wiidakas, 1967), it may be possible to enhance the feed value of barley or oat haylage by growing these cereals together with field pea. Izaurralde et al. (1989) concluded that intercropping barley with field peas significantly increased crude protein content of the hay produced. Similarly, protein yield sometimes was increased when oats were intercropped with field peas in western North Dakota rather than grown alone (Carter and Larson, 1964). While these North Dakota researchers reported that hay yields generally were decreased when oats were intercropped with either field pea (or vetch), their data reveal several exceptions. For example, dry matter production of oat-field pea mixtures compared favorably with monocropped oat in recropped environments at Dickinson, Minot, and Williston.
Recent work indicated that dry matter yield was maintained when oats and peas were intercropped at Dickinson (Carr and Martin, 1996). The influence of intercropping on hay yield and protein content must be determined for widespread adoption of this practice in the Southwest. For this to be known, the influence of cereal to pea plant populations on intercrop performance must be established, as must be the optimum time for harvesting the mixed forage.
Alfalfa has been grown for decades in western North Dakota. Still, obstacles to successful alfalfa establishment exist for many farmers and ranchers. An important question continues to revolve around alfalfa establishment methods: should alfalfa be clear seeded or grown with a nurse crop? Work is needed to determine the best method for seeding alfalfa in western North Dakota. Research also is needed to determine optimum plant stand for maximum alfalfa hay production in western North Dakota.
Flax and crambe are industrial oilseed crops which offer advantages to crop producers if they are incorporated into crop rotations in western North Dakota. Canola is an edible oilseed crop that offers similar benefits. Adaptation screening trials are needed to identify the cultivars which are best adapted to growing conditions in this portion of the state.
MATERIALS AND METHODS
Objective 1
Cultivar Adaptation Trials and Pea Production Trials. Field pea and lentil were evaluated in cultivar comparison trials at the Dickinson. A corn cultivar trial also was conducted. Seed of 25 field pea and 9 lentil cultivars were provided by the Carrington and North Central Research Extension Centers for testing at Dickinson. Corn seed was solicited from private seed companies. Cultural practices including tillage and seeding, fertilization, herbicide application, and harvesting followed currently acceptable agronomic procedure in implementing and maintaining cultivar comparison trials.
Cultivars were evaluated using a randomized complete block design with four replicates. Individual plot dimensions were 28 by 6 ft for all crops except corn. Corn plot dimensions were 50 by 6 ft. Variables measured in each plot varied, depending on the crop being considered.
The suitability of placing 'pop-up' N fertilizer with pea seed at planting was evaluated at Dickinson and Glen Ullin, as were alternative seeding rates for pea at Glen Ullin. Experimental design and plot dimensions were the same as those for the pea cultivar adaptation trials.
Data collected from each trial were analyzed by computer using a statistical software program.
Cereal-Pea Cutting-Date Trial, Cool and Warm-season Forage Trial, Forage Barley and Oat Trial , Alfalfa Establishment and Alfalfa Density Trials.
Dumont oat and Horsford barley were sown alone and mixed with Trapper field pea at different rates to compare forage production among alternative intercropping strategies. Other cool and warm season forages were grown, and forage yield comparisons made, with the cereal-pea mixtures. Each experiment was arranged in a randomized complete block design with four replicates. Individual plot dimensions were 28 by 6 ft. An experiment was also conducted to determine which of four cereal growth stages was optimum for forage yield and quality of cereal-pea mixtures: late boot, milky kernel, soft dough, or hard dough.
Variables measured in each plot included plant(s) height and forage yield. Forage yield must still be determined.
Under the direction of Dwain Meyer, an alfalfa establishment experiment and an alfalfa density experiment were begun at Dickinson in 1994 and 1996, respectively. Experimental design are described elsewhere in this annual report by Dr. Meyer.
Data were analyzed by computer using a statistical software program.
Objective 2
Crambe, canola, and flax cultivar adaptation trials were established at Dickinson, along with adaptation trials for canola and flax at Glen Ullin. Cultural practices including tillage and seeding, fertilization, herbicide application, and harvesting followed currently acceptable agronomic procedure in implementing and maintaining cultivar comparison trials.
Cultivars were evaluated using a randomized complete block design with four replicates. Individual plot dimensions were 28 by 6 ft at all locations for all crops. Variables measured in each plot varied, depending on the crop being considered.
RESULTS
OBJECTIVE 1
Corn
Average silage yield for corn was 5.7 tons of dry matter per acre among the nine hybrids evaluated in 1996. Silage yield was comparable among 7 of the 9 hybrids evaluated; Pioneer corn hybrids 3963 (79 d) and 3970 (76d) produced less silage than the other hybrids developed by Pioneer and other corn seed developers that were evaluated at Dickinson.
Grain yield averaged 79 bu/acre among the nine corn hybrids evaluated; this was the first year grain had been produced since 1992 at Dickinson. The corn hybrids did not differ (p < 0.05) for grain yield. Test weight ranged from 50.6 lbs/bu (Dekalb 442) to 58.9 (Pioneer 3970).
The differences in silage yield were not observed among the hybrids, in part because of soil and other uncontrolled variability. Silage yield for the two hybrids included in the corn trial at Dickinson over the last three years has been around 4 tons/acre.
For the first time in three years, corn produced grain at Dickinson. Grain yield ranged from 43 bushels per acre for Pioneer 3963 to 62 bushels per acre for Pioneer 3905, though significant differences in grain yield among hybrids were not observed. Test weight was light (<56 lbs/bu), with the exception of grain produced by Cargill 1077 (58.6 lbs/bu).
Cool Season Annual Forages
The triticale cultivar '2700' produced more hay (4.2 tons/acre) than other cultivars or intercrop evaluated at Dickinson in 1996. Intercropping triticale or oat with Trapper pea reduced hay production compared to growing the cereal cultivar as a sole-crop. This was expected since the rate at which the cereal was sown was reduced in cereal-pea intercrop compared to cereal sole-crop (Carr and Martin, 1996). Intercropping 'Whitestone' oat with semi-leafless pea cultivar 'Carneval' did not affect hay production compared to intercropping Whitestone with Trapper pea.
Forage Barley and Oat Cultivars
'Bay' (forage-type) oat, 'Chopper' (forage-type) barley, 'Haybet' (forage-type), and Dumont (grain-type) oat produced the most hay among the 10 cereal cultivars and two oat-pea intercrops that were evaluated in 1996. Over the past two years, Haybet barley has produced the most hay among the cultivars and intercrops evaluated. Dumont oat-Trapper pea mixtures produced less hay than Dumont oat sole-crop, even when Dumont oat was seeded at a sole-crop rate in the mixture and Trapper pea was seeded at 1.5x the sole-crop rate. Horsford barley, perhaps the most widely grown forage-type barley grown in western North Dakota, has produced less hay than Haybet barley in both years the two cultivars have been compared for hay production. Paul oat was included in this experiment for the first time in 1996; hay production by Paul oat was less than for five other cultivars (Bay, Dumont, Chopper, Haybet, and the barley cultivar B 7518) included in the experiment.
Cereal/Pea Cutting Dates
Hay yield generally increased for oat sole-crop, oat-pea intercrop, and oat-lentil intercrop as the cutting date was delayed from early heading to the kernel hard dough stage. This general trend also existed for barley sole-crop and barley-pea intercrop, except when cutting was delayed from kernel soft dough to hard dough stages. In this instance, hay yield was reduced, probably because of leaf senescence of barley and oat plants.
Alfalfa Establishment and Density Evaluations
Establishing alfalfa with an oat nurse crop enabled an oat hay crop (1.8 tons/acre) to be produced in 1996; too little hay was produced when alfalfa was clear seeded in a no-tillage seedbed for any forage to be harvested in 1996. No difference in hay yield was measured between second and third year alfalfa stands between plots where alfalfa had been established with an oat nurse crop, and in plots where alfalfa had been clear seeded in a no-tillage seedbed.
Less than a ton of hay (avg. 0.6 tons/acre) was produced across seeding rates in the alfalfa density trial established at Dickinson in 1996. Increasing the alfalfa seeding rate from 1 lbs PLS/acre to 4 lbs PLS/acre did increase hay yield from 0.7 to 0.8 tons/acre. Increasing the seeding rate from 4 lbs PLS/acre to 16 PLS/acre did not increase hay yield, and yield was reduced as the seeding rate was increased to 32 lbs PLS/acre.
Hay yield was increased as alfalfa plants were arranged in a hexagonal, equidistant pattern and plant stand density was increased from 10 to 30 plants/m2. Further increases in plant stand density did not affect hay yield.
Warm Season Annual Forages
German millet and the sorghum x sudan cross 'Sudax ST6E) produced more hay (avg. = 4.7 tons/acre) than the other millet, sudangrass, sorghum x sudan, and forage legume cultivars evaluated. Least amount of hay was produced by foxtail dalea (1.6 tons/acre), a forage legume which may have some potential in western North Dakota as a green fallow cover crop. Overall yield of the 7 cultivars evaluated was 3.6 tons/acre.
Field Pea - Seeding Rate
More peas were established as the pea seeding rate was increased from 300 000 (100 lbs/acre) to 400 000 (130 lbs/acre) PLS/acre at Glen Ullin. However, altering the seeding rate within this range failed to affect pea seed yield. However, pea plots seemed easier to harvest mechanically as more peas were planted.
Field Pea - Cultivar Evaluations
Seed yield of the 25 pea cultivars evaluated at Dickinson averaged 1722 lbs/acre (29 bu/acre) in a field where rye had been plowed down in 1995. At Glen Ullin in a field where hard red spring wheat was grown in 1995, seed yield for the 12 pea cultivars averaged 2823 lbs/acre (47 bu/acre). These data suggest that field pea is adapted to western North Dakota conditions; total annual and growing season precipitation was less than the 30-year average in 1996.
Trapper probably remains the most widely grown pea in western North Dakota. However, the cultivar trials at Dickinson and Glen Ullin suggest that other pea cultivars exist which will produce more seed than Trapper in western North Dakota. For example, seed yield for Trapper is the lowest of the 4 cultivars that have been evaluated at Dickinson over the past three years: 'Profi' (2024 lbs/acre), 'Express' (2008 lbs/acre), 'Century' (1916 lbs/acre), and Trapper (1837 lbs/acre).
Field Pea - N Pop-Up Evaluations
Applying N as urea with pea seed reduced pea plant stand at both the 5 lbs N/acre and 10 lbs N/acre rates at both Dickinson and Glen Ullin. Across both sites, pea plant stand was reduced an average of around 15% for each 5 lbs N/acre increment that was placed with the seed. However, this reduction in pea plant stand failed to affect seed yield, test weight, or seed weight. These data indicate that there is no benefit to applying small amounts of urea with pea seed in western North Dakota under dryland conditions.
Lentil - Cultivar Evaluations
Seed yield of the 9 cultivars evaluated at Dickinson averaged around 950 lbs/acre, while that of the 6 cultivars evaluated at Glen Ullin averaged about 1400 lbs/acre. Seed yield of the cultivars developed in Canada ('CDC Matador', 'CDC Redwing', 'CDC Richlea') were the highest yielding cultivars at Dickinson; yield was comparable among the cultivars evaluated at Glen Ullin except for that of 'Chilean' and 'Laird', which was less.
'Crimson' produced less seed (810 lbs/acre) than several other cultivars evaluated at Dickinson in 1996. In past years, Crimson has generally been among the highest yielding cultivars evaluated. It is unclear why Crimson lentil was a relatively poor yielding cultivar in 1996; this cultivar was developed and released for dry regions at northern latitudes by USDA-ARS scientists located at Pullman, WA.
Objective 2
Canola - Cultivar Evaluations
Canola yield averaged around 900 lbs/acre among the 7 commercial cultivars evaluated at Dickinson in 1996, and almost 1100 lbs/acre among the 4 cultivars evaluated at Glen Ullin. Damage from blister beetles to late maturing cultivars at Dickinson reduced the amount of seed harvested from plots of 'Bullet', 'Ebony', 'Jewel', 'OAC Springfield', and 'Pearl'. This damage also increased seed yield variability within replicates since feeding by the beetles what not uniform across the experiment or across the plots of any cultivar evaluated. As a result, a high coefficient of variation (20.9%) occurred for seed yield when data were analyzed at Dickinson and cultivars could not be ranked by mean comparison methods. At Glen
Ullin, 'Hyola 308' produced more seed than the other three cultivars evaluated ('Crusher', 'Cyclone', and 'Reward').
Crambe - Cultivar Evaluation
Seed yield of the 5 commercial cultivars evaluated at Dickinson in 1996 averaged about 1750 lbs/acre. 'Meyer' crambe produced less seed than any of the other cultivars evaluated. 'Belann' crambe produced the most seed (2126 lbs/acre), although this amount was comparable to that produced by the cultivars 'Indy' (1840) and 'Prophet' (2109 lbs/acre).
Flax - Cultivar Evaluation
Seed yield of the 5 flax cultivars evaluated at Glen Ullin in a field where hard red spring wheat was grown in 1995 averaged around 35 bu/acre. 'Linora' flax produced the most seed (37.6 bu/acre), although comparable amounts were also produced by the cultivars 'Neche', 'Omega' (yellow seeded), and 'Verne'. The data indicate that flax can be productive when grown in selected environments in western North Dakota.
