  abstract = {{A} series of experiments was conducted where a range of injuries due to rice pests (pathogens, insects, and weeds) was manipulated simultaneously with a range of production factors (fertilizer input, water supply, crop establishment method, variety) in different seasons and years. {T}hese factors were chosen to represent lowland rice production situations characterized in surveys conducted in tropical {A}sia and their corresponding range of attainable yield. {E}xperiments complemented one another in exploring the response surface of rich yields to yield-limiting and yield-reducing factors. {T}he resulting experimental data base consisted of 445 individual plots and involved 11 manipulated injuries in a multiple regression model involving factors generated by principal component analysis on injuries that adequately described the variation in actual yield. {O}ne major finding was that some (attainable yield x injury factors) interactions significantly contributed to the description of variation in actual yield, indicating that some injuries (or their combinations) had a stronger or weaker yield-reducing effect, depending on the level of attainable yield. {F}or instance, yield losses due to sheath blight, weed infestation, and rice tungro disease tend to increase, remain stable, and decrease, respectively, with increasing attainable yields. {B}ack-computations using the principal component regression model estimated yield losses caused by individual injuries, using the mean injury levels in a population of farmers' fields surveyed across tropical {A}sia. {T}he results indicate that sheath blight, brown spot, and leaf blast are diseases that cause important losses (between 1 10%) regionally. {A}mong the insect injuries, only white heads caused by stem borers appear of relevance (2.3%) yield losses)...
