Croplan 8221 harvested on Sept 1











This is Croplan Genetics 8221 variety grown by Ralph Ross Farms and harvested the 1st day of Sept.


Hank was chopping this and he thinks it turned off 30-34 tons of silage per acre. He has weighed other using the same trucks so should be pretty acurate on this estimate.


He likes the fact that this is a little earlier relative maturity.


This is a shorter height relative to some other silage varieties but generally has exceptional grain.


This field produced 161 bushels using the formula method of counting kernels per ear x plant population.


Calculations based on actual shelled corn from randomly harvested ears measured 266 bushels. Ears are harvested by starting at a random point in the field moving forward 10 stalks and pulling an ear and then pulling an ear from every 10th stalk as you move through the field. These ears are then shelled and weighed to calculate bushel weight per acre.


Average row spacing was 29.4".


Hank specifically likes this as compared to the 8505 he planted. He could tell that with the 8221 where he sprayed herbicide a second time and ran over some plants it was much more forgiving and came back where the 8505 did not.


On September 13th I measured another field of 9009RH that they grew in the Bethel area. Row spacing and population was the same. This field tested 229 bushels based on counting the kernels method and 367 bushels based on weighing the shelled corn.
