Effect of Lodging on Yield, Test Weight, and Other Seed Characteristics of Spring Barley Grown Under Flood Irrigation as a Winter Annual¹

Abstract

Synopsis The grain yield, test weight, and weight per 1,000 seeds were decreased as a result of 90° lodging treatments of irrigated spring barley grown as a winter annual. Lodging treatments of 45° and 90° resulted in a decrease in the percentage of plump kernels and the grain color score. The percentage of thin kernels was increased as a result of 90° lodging treatments.

Control of lodging and reduction in plant length in rice (Oryza sativa L.) with the treatment of Trinexapac-Ethyl and sowing density

“…Rice is the staple food of much of humanity, and this paper examined a method of mitigating against a particular constraint on rice production, lodging. Lodging may cause the loss of grain yield and quality (Day 1957;Weibel and Pendleton 1964;Cooper 1971), and so it is vitally important to develop methods to reduce lodging. In this study, plant length, lodging, and yield ).…”

“…In a high-yielding environment, lodging is the most important constraining factor on yield for most cereals crops, including rice (Setter et al 1997). Lodging negatively impacts both grain yield and quality (Day 1957;Weibel and Pendleton 1964), in part through a 60%-80% reduction in rice canopy photosynthesis (Setter et al 1997). More practically, lodging reduces working efficiency by about 25% by making machine harvesting difficult (Lim et al 1997).…”

Screening for lodging resistance in spring wheat breeding programmes

“…Grain yield reduction in cereals almost always follows lodging, with the magnitude of loss dependent on the cultivar, growth stage and severity of lodging Stapper 1987, Jedel andHelm 1991). Reductions in kernel number, kernel weight and/or test weight have been reported as a direct result of lodging in winter wheat (Laude andPauli 1956, Weibel andPendleton 1964) and barley (Day 1957, Briggs 1990.…”

Recurrent selection for lodging resistance in oats

“…The effects of lodging on yield, grain quality, and harvesting difficulties have been reported in many studies (Weibel and Pendelton, 1964;Larson and Maranville, 1977;Day, 1957;Pendelton, 1954). Laude and Pauli (1956) reported 3 to 37 percent reduction in grain yield due to lodging of wheat (Triticum aestivum L.), and Pendelton (1954), using artificial lodging, found similar reductions with oats (Avena sativa L.).…”

“…Laude and Pauli (1956) reported 3 to 37 percent reduction in grain yield due to lodging of wheat (Triticum aestivum L.), and Pendelton (1954), using artificial lodging, found similar reductions with oats (Avena sativa L.). Day (1957), who worked with barley (Hordeum vulqare L.); reported 50 percent yield reduction from lodging, and a reduction in grain quality characters, such as test weight, kernel weight, and number of kernels per plant.…”
