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.
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

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-
