Introduction

Canola acreage in Montana is holding steady and in 2016 61,000 acres were harvested, yielding 91,500,000 lbs. Currently, Montana is ranked third nationally, behind North Dakota and Oklahoma for the number of acres harvested. This report summarizes canola performance from four Montana Agricultural Research Centers and is presented in table form. It is advised to pay special attention to the results of those trials grown with similar practices and environments to your own. In addition to location, it is important to review variety performance over time.

Objective

The objective of the Montana Statewide Spring Canola Variety Trial is to evaluate the agronomic performance of available canola varieties and breeding lines submitted by commercial and university entities at four research locations throughout the state. The information obtained from these trials is intended to provide canola growers in Montana with reliable, unbiased information regarding which canola varieties are best suited to their specific production environment.

Procedures

In 2016, twenty-five spring canola varieties (Brassica napus), were submitted by seven sponsors (Table 1). The seed was distributed to four agricultural research centers: Northern (Havre), Northwestern (Kalispell), Eastern (Sidney), and Western Triangle (Conrad) for testing during the 2016 growing season (Figure 1). Test protocol and management guidelines were provided to personnel at each location.

Seeding rates were calculated using the following formula: (10 plants per sqft x TKW x 9.6) / 80% survival. The entries were replicated four times using a randomized complete block design.

Seeding date, field crop history, tillage, fertility program, pesticide application, and harvest date are presented for each location.

Data was collected on: number of plants per square foot, date of 50 percent flower, plant height, percent shatter and lodging (visually estimated on a score from 0 to 100 with 0 equal to none and 100 equal to completely shattered or lodged), yield, percent oil, and test weight.

The variety data are presented by location in Tables 5 through 8. The Least Significant Difference (LSD) values are presented for making pairwise comparisons between treatment means (varieties). If the difference between two treatment values within a column does not exceed the LSD value, it means that the entries are statistically equal for that particular response variable. If the difference exceeds the LSD value, then the entries are statistically different for that particular response variable. When using the LSD values to make pairwise comparison of treatment means, it is recommended to do so only if the probability values for treatment is less than 5% (Pr>F=0.05). This is referred to as “Fisher’s” protected LSD. Using a probability level of 5 percent means that there is a 5 percent probability that the treatment differences are not statistically significant. Or stated another way, there is a 95 percent probability that the treatment differences are statistically significant. A large coefficient of variation (CV) indicates a large amount of variation that could not be attributed to differences in the varieties.

Statewide summaries of variety, yield, and oil content are presented in Tables 3, 4, and 9 through 13.

The following results and summaries are for informational purposes only. The presentation of data for the varieties evaluated does not imply approval or endorsement by MSU-MAES.

Results/Summary

Northern Agricultural Research Center (NARC), Havre

Plant densities average of 3.7 plants/sqft (Table 5), indicating that a lower percent survival should be used when calculating seeding rates for environments similar to Havre. Yields averaged 35.6 bu/A and ranged from 23.8 to 45.6 bu/A, with seven varieties yielding statistically equivalent to the highest yielding variety ‘G49773’. Test weight averaged 48.4 lb/bu and oil content averaged 48.2 percent.

Northwestern Agricultural Research Center (NWARC), Kalispell

Plant density exceeded the targeted population with an average of 14.9 plants/sqft (Table 6). Yields averaged 41.5 bu/A and ranged from 25.0 to 56.6 bu/A. Three varieties yielded statistically equivalent to the highest yielding variety, ‘HyClass 972’. Test weight averaged 49.4 lb/bu and oil content averaged 49.3 percent.

Eastern Agricultural Research Center (EARC), Sidney

The average plant density was 6.3 plants/sqft (Table 7). Yields averaged 31.1 bu/A and ranged from 15.5 to 38.4 bu/A. Twelve varieties yielded statistically equivalent to the highest yielding variety, ‘HyClass 955’. Average test weight and oil content were 49.4 lb/bu and 44.5 percent, respectively.

Western Triangle Agricultural Research Center (WTARC), Conrad

Plant density averaged 8.1 plants/sqft (Table 8). Yields averaged 20.3 bu/A and ranged from 13.5 to 25.0 bu/A. Thirteen varieties yielded statistically equivalent to the highest yielding variety, ‘HyClass 930’. Test weight averaged 47.7 lb/bu and oil content averaged 45.5 percent.

Future Plans

With global canola demand and Montana acreage increasing, coupled with continued support from the canola industry and research center personnel, multi-location canola evaluations will continue in 2017.
