Imagine a test plot with 30 hybrids, every fifth entry is a check, one set of six rows is at 39,000 and the other is at 45,000. In the middle of the plot two strips were left where no fungicide was aerially applied. On both ends of the plot, fungicide was applied crosswise so that all hybrids were treated equally. In addition, there are some side trials at populations up to 55,000 plants per acre.
So is this a nightmare to interpret? Or will the farmer be able to take away meaningful data on this plot, put in by himself and cooperating seed reps on his farm?
Nick Wenning, Greensburg, is confident that he can make heads and tails of the data when he has a chance to analyze it this winter. He is convinced he can use it to see how hybrids compare to each other, how hybrids compare at various populations, and which hybrids responded to fungicide and which didn't.
He's not going to wave a magic wand over the data. But he is going to use software to sort out the different properties he wants to see. He will even be able to pull out the non-fungicide strips in the middle of each pass and compare them to parts of the field that got fungicide, hybrid by hybrid. The non-fungicide strips showed up as a slightly different color on the yield monitor on most hybrids as he crossed the field on each pass.
He has an Ag Leader Integra display for his yield monitor. This winter he will use software to go back into the yield files accumulated by the combine monitor and sort out what he wants to know. The data is pinpointed by GPS, using the WAAS differential correction signal. His goal is to use his results as he makes decisions for the farm for next season.
