This dataset is made up of data from three studies.  The first involves a flight cage trial where oilseed rape plants were grown under four fertiliser treatments and then exposed to insect pollination or not. A number of yield parameters were then collected from each plant.  The second study involved a field study across three oilseed rape fields with insect pollinator exclusion cages placed over areas of the crop. Yield parameters were then collected from plants under these exclusion cages as well as open controls. The final dataset includes field data collected from a number of oilseed rape study plots where plant yield, seeds per pod, pod number and thousand grain weight has been established from a number of individual plants across these plots.
