Pea Seed-borne Mosaic Virus (PSbMV) in Field Peas and Lentils - PP1704
Pea seed-borne mosaic virus (PSbMV) is an economically damaging viral pathogen of field peas and lentils that can cause significant losses in seed yield and quality, especially when infections occur before or during bloom. It has been observed on field peas and lentils in North Dakota and on field peas in Montana. PSbMV is distributed worldwide, and it presumably was introduced to North Dakota and Montana on seed imported from other regions.

North Dakota Hard Winter Wheat Variety Trial Results for 2013 and Selection Guide - A1196
During the 2012-13 growing season, 220,000 acres were planted to winter wheat, with 205,000 acres harvested. The area harvested was down substantially from last year’s record area harvested of 700,000 acres. The state’s winter wheat yield this season was estimated at 43 bushels per acre (bu/a), which also is down from last year’s yield of 55 bu/a. Establishing winter wheat was problematic due to dry conditions in the fall of 2012, which not only impacted the area planted,

North Dakota Soybean Variety Trial Results for 2013 and Selection Guide - A843
Soybean variety selection should be based on maturity, yield, seed quality, lodging, iron deficiency chlorosis tolerance and disease reaction. Later-maturing varieties tend to yield more than early maturing varieties when evaluated at the same location. After determining a suitable maturity for the farm, comparing yields of varieties that are of similar maturity is important. Although later maturity increases yield potential, later- maturing cultivars are more risky to grow than earlier-maturing varieties because an early fall frost may kill a late-maturing variety before the beans have filled the pods, which will reduce yield greatly.

North Dakota Dry Bean Variety Trial Results for 2013 and Selection Guide - A654
The agronomic data presented in this publication are from replicated research plots using experimental designs that enable the use of statistical analysis. The LSD (least significant difference) numbers beneath the columns in tables are derived from the statistical analyses and only apply to the numbers in the column in which they appear. If the difference between two varieties exceeds the LSD value, it means that with 90 (0.10 level) percent probability, the higher-yielding variety has a significant yield advantage. If the difference between two varieties is less than the LSD value, then the variety yields are considered similar. The abbreviation NS is used to indicate no significant difference for that trait among any of the varieties. The CV is a measure of variability in the trial. The CV stands for coefficient of variation and is expressed as a percentage. Large CVs mean a large amount of variation that could not be attributed to differences in the varieties.

North Dakota Corn Hybrid Trial Results for 2013 - A793
This publication reports the results of corn hybrid trials that were conducted by NDSU research and Extension personnel throughout North Dakota. The hybrids tested were entered voluntarily by the companies that market them, and the management of these trials was financed partially by the entry fee those companies paid. Links to the participating companies are summarized in Table 1. Additional information and data for a given location may be available at www.ag.ndsu.edu/varietytrials/corn. When selecting a hybrid, look at its performance at multiple locations and/or across years if possible.

Air Temperature Inversions Causes, Characteristics and Potential Effects on Pesticide Spray Drift - AE1705
Temperature inversions are micro-climatic events that can significantly contribute to off target movement of pesticides. This publication explains in detail: what they are, why they develop, how they are impacted by land condition, how to identify them, how to measure them, and how to minimize their impact on pesticide applications. Professional applicators, private applicators using pesticides on their farm or ranch, state and federal regulators, pesticide safety educators, researchers, and industry should benefit from the comprehensive explanations found in AE1705.

North Dakota Barley, Oat and Rye Variety Trial Results for 2013 and Selection Guide - A1049-13
Barley, oat and rye varieties currently grown in North Dakota are described in the following tables. Successful production of these crops depends on numerous factors, including selecting the right variety for a particular area. Characteristics to evaluate in selecting a variety are: yield potential in your area, test weight, straw strength, plant height, reaction to problematic diseases and maturity. Selecting varieties with good quality also is important to maintain market recognition. Because malting barley is purchased on an identity-preserved basis, producers are encouraged to determine which barley varieties are being purchased by potential barley buyers before selecting a variety. When selecting a high-yielding and good-quality variety, use data that summarizes several years and locations.
