Abstract
Lodging of a rice (Oryza sativa L.) plant just before harvest can significantly impact the quality of the harvested crop yield as well as the market returns received for sale of the crop. The purpose of this study was to quantify the level and significance of lodging on the milling yield and market price of rough rice. A 2‐yr study was conducted in the major rice‐growing regions of Arkansas, Louisiana, Mississippi, and Texas to evaluate the impact of early and late lodging before harvest. The study included two rice planting dates and a range of rice varieties predominately grown in the regions. Results suggest that lodging does have a significant impact on milling yield, although impacts of planting date and time of lodging were not significant. Lodging was found to have a greater impact on whole grain (head rice) milling yield than total grain milling yield. Head rice yield reductions of 30.19 to 55.30 g kg–1 were observed. Although market price effects will vary with the general level of average rough rice market prices in a given year, results for the 2011 and 2012 crop years showed market price reductions of .0075 to .0119 per kg, due to crop lodging impacts on milling yield alone.
