Factors Influencing Yield Variability in the Arkansas Cotton Research Verification Trials (CRVT)

Donald E. Plunkett, N.R. Benson and W.C. Robertson


 
ABSTRACT

The relationship of twenty-two factors were analyzed from nine fields per year for the 1996 and 1997 cotton growing seasons in Arkansas. An above average production was seen during each year throughout the state. Regression analysis were performed on data collected from the Cotton Research Verification Trials conducted by the Cooperative Extension Service in each of those years to determine whether any of the 22 factors directly correlated to yield. Analysis indicated that the variables studied did not correlate well with yield for either year. The lack of correlation may have been due to (1) most fields being planted within the optimum planting window for the state, (2) good emergence followed by moderate weather, especially temperatures during the fruiting and boll development periods.
