2023-11-16 KBS Harvest GLBRC main site treatment G3 (sorghum) and G6 (miscanthus) main plots. Equipment Used: All plots were harvested with the JD 7350 self-propelled forage harvester equipped with a JD 676 cutting head. Plant material was chopped into a Gnuse forage wagon that is fitted with load cells to determine weight of harvested biomass. Cutting height of remaining plant stubble was 4-6 inches in all reps. Grab samples from each rep was placed in paper bags weighed for wet weight and placed in plant dryer and reweighed to determine percent moisture for each replication.
2023-11-16 KBS Jarrod Rhoades mowed corn stover in G1 main plots: Reps 1, 2, 3, 4, & 5. Corn stover was mowed into windrows so that they could be bailed. The 6 rows (15 ft) in the west micro-plots of each rep were not mowed. Equipment Used: JD 7420a tractor and Loftness 15 ft Draper Windrower Shredder. Joe Simmons bailed corn stover with Krone 1270 square baler. Equipment Used: JD 7520 tractor with Krone 1270 square baler. Equipment Used: JD 7420 tractor (with loader) was used to move/load bales. Equipment Used: Dodge truck and gooseneck trailer were used to move and weigh bales. Portable scale was put on the rear of gooseneck and bales were place on scale to obtain weight. Bales were taken to KBS Dairy Center to be used for bedding for the cows.
2023-11-14 KBS Harvested biomass in G4, G5, G7, G9, and G10 plots, all reps. Harvested the main-plot area. Wet grab samples were collected and placed in the Grieve plant drier to determine percent moisture in the biomass. 2023 was the first year that all the biomass was mowed with the JD discbine and chopped with the JD self-propelled chopper equipped with a 'hay (biomass) pick-up head'. In past years the biomass was 'direct' cut with the JD selp-propelled chopper equipped with 'kemper' direct harvesting head. See notes relating to the harvesting equipment heads under the JD 7350 sel-propelled harvester 'chopper'. The 7350 self-propelled forage harvester/chopper is equipped with a JD 676 Rotary Rowless Header, (Kemper Harvesting Head), 15 ft (4.57 meter) wide, or a JD 630B Windrow Pickup Head with Finger Auger, 3.0 Meter (9.8 ft) Wide.
2023-11-14 KBS Harvested corn in the main plot area of G1 plots, reps: 5, 4, 3, 2, & 1.
2023-11-13 KBS Corn Micro-plot harvest. Harvested GLBRC G1 corn from the micro-plot area, all reps, (plus corn stover, and minus corn stover micro plots)(west and east side of all plots). Harvested with the Kincaid plot combine. For each micro-plot all six rows were harvested (the six rows on the west and east side of each plot were harvested). The middle two rows of the six row micro-plot area were sampled and tested for moisture with Dickey John grain tester. Plot weight and moisture were obtained from the on-board Mirus Harvest Master computer/software weighing system.
