Title

Application of GOSSYM to Yield Decline in Cotton. I. Systems Analysis of Effects of Herbicides on Growth, Development, and Yield¹

Other claims from this paper (6)

Intervention effect Moderate shallow root reduction gave a small predicted yield increase.
Intervention effect Deeper or greater root reduction predicted up to 40% less cotton lint yield.
Intervention effect Unfavorable weather reduced predicted yield.
Intervention effect Increasing root reduction depth or percentage and reducing permeability lowered root growth throughout the season.
Intervention effect Increasing root reduction depth or level raised nitrogen and water shortages.
Recommendation The authors concluded improper herbicide application contributed to cotton yield decline.

Other claims from this paper (10)

Intervention effect Adapted maize hybrids tended to yield more than early season hybrids when planted before 20 May.
Intervention effect The overall effects of hybrid maturity class on maize were minor.
Observation The optimum planting date for maize was near 6 May.
Intervention effect Planting either 2 weeks before or after 6 May reduced maize yields by less than 5%.
Association Averaged across environments, the interaction of planting date with plant density and plant distribution was not significant.
Recommendation Before mid May, plant density and plant distribution within the row are the major factors to consider in maize replant situations.
Association After mid May, calendar date increases in importance for maize replant decisions.
Method / resource A model for uniformly spaced maize plants predicts yield from planting date and population density.
Intervention effect Small gaps in the row reduced maize yield by an average of 1.9% compared with uniform spacing within the row.
Intervention effect Large gaps in the row reduced maize yield by 5.4% compared with uniform spacing within the row.
