2021-10-22	Harvest	Used Kemper harvester/weigh system to take yields on treatments G5, G6, G7, G9, G10. One pass(except trt 5, 32 feet) per each split plot(7.5' width), plot weight recorded, and subsample taken for moisture correction and lab analysis. G5, G6, G7, G9, G10 plots cleared off with Kemper harvester. Cut height, 6 inches.	MSG10R1	Kemper harvester / tractor / weigh container	5264
