CropInsurance TODAY 2012 Research Review By Dr. Mark Zarnstorff, NCIS Each year NCIS sponsors research projects on a variety of crops. The purpose of the research varies. The purpose of the research can be to study new crops or changes in crop varieties/practices, to verify accuracy of loss charts and procedures, or develop improved loss instructions. All research projects are conducted for a period of at least three years. If, for some reason, results are not obtained for one or more years, the research project can be extended. University experiment stations and agricultural colleges conduct the research, often at more than one location across the United States. The results of the 2012 research program are summarized below. It is important that these results are not used exclusively, but combined with the results from previous years’ research and any subsequent research. In order to provide the best loss adjustment proceedures for NCIS members. Canola–Oklahoma Research on canola has focused on the spring types which have been grown in Canada and the upper tier of states in the US from the early 1980’s. The research and loss procedures were developed based on the spring type. Recent breeding has improved the winter survival of winter types of canola. The Different stages of bolting winter canola in Oklahoma. climate and growing season/conditions differ tremendously in Oklahoma and Kansas where the emphasis in winter canola production is. The research that is being done in Oklahoma is being done on these new winter canola varieties to determine if the response to damage at the various growth stages different that that observed with spring canola types. The research in Oklahoma was done on winter canola hybrid to determine the influence of early defoliation (8 to 10 leaf) and damage to the developing flower stem (bolt/ early flower) on canola production. Previous research has studied spring canola types. It was felt that with development of viable winter canola varieties and industry, that research should be done to determine if there are differences in the response to damage between these two types. The plots were seeded in late September 2011 on a conventionally tilled seedbed with harvest occurring in mid-May 2012. Defoliation treatments of 50 and 100 percent were applied to eight to 10 leaf canola in late February 2012. The 50 percent defoliation resulted in only a four percent loss while the 100 percent defoliation resulted in a 52 percent loss. Research on spring types has shown approxi- Table 1.
