Cotton yield mapping was started at Texas A&M University in 1994 with the support of Deere & Co. and the Texas Agriculture Extension Service. The objective of the project was to develop a yield mapping system for cotton strippers using load cells to measure the weight increase of the basket during harvest. The basket is weighted continually by suspending the basket on load cells at the basket pivots and support bar. Desired accuracy for each yield data points is +/- 1/4 bale/acre. In 1997, the yield mapping system met this desired accuracy for 72% of the points.
