Effect of seeding rate on grain quality of winter wheat

Abstract

Planting density is important factor which influence yield and quality of wheat (Triticum aestivum L.) For this reason, in scientific investigations is constantly investigated optimization of plant number per unit area. The objective of this study was to determine the influence of seeding rate in grain quality of winter wheat cultivars. The experiment was conducted with four winter wheat genotypes ('Ana Morava', 'Vizija', 'L-3027', and 'Perla') at the Small Grains Research Centre of Kragujevac, Serbia, in 3 yr at two seeding rates (SR1 = 500 and SR2 = 650 germinating seeds m -2 ). The 1000-kernel weight, Zeleny sedimentation, and wet gluten content in divergent wheat genotypes were investigated depending on the seeding rate and ecological factors. Significant differences in quality components were established between investigated seeding rates. The highest values of all investigated quality traits were established in SR2 variant when applied 650 seeds m -2 . Genotypes reacted differently to seeding rate. 'Perla' in average had the highest mean sedimentation value (42.2 mL) and wet gluten content (33.76%) in SR2 variant and this cultivar responded the best to seeding rate. Significant differences for sedimentation value and wet gluten content were found among cultivars, years, seeding rate, and for all their interactions. Also, ANOVA for 1000-kernel weight showed highly significant differences among investigated varieties, seeding rate and growing seasons, but all their interactions were not significant. In all investigated genotypes, better quality was established in SR2 variant when applied 650 seeds m -2 .

Analysis of Agro-Morphological Characters in Wheat (Triticum aestivum L.) Genotypes for Yield and Yield Components

“…Therefore, best performing genotypes of this study can be selected and incorporated for further breeding program. Similar findings have also been reported by Zecevic et al, (2009) andAmagai, et al, (2014).…”

Effect of foliar application of Cu, Zn, and Mn on yield and quality indicators of winter wheat grain

“…This could have been influenced by different thermal conditions in the winter of 2012-2013, which encouraged the transition to the vernalization stage combined with the optimum distribution of precipitation. Zecevic et al (2014) confirmed the effect of weather conditions in the growing Sept periods on the analyzed parameters of the quality of wheat grain (proteins, gluten, and Zeleny index). After analyzing the technological indicators for the grain in the second year of the experiment, increases were found in protein content (8.9%), gluten content (29.0%), Zeleny sedimentation index (34.7%), bulk density (9.3%), and grain hardness (28.6%).…”

Grain Yield and Quality of Wheat as Affected by Cultivars and Seeding Rates

“…The reasons behind this deficit might be due to poor crop management, including seeding rates and the use of old cultivars. For achieving high yield and quality of wheat, it is necessary to use all the cultural practices completely and on time and adapt them to cultivars [5]. So, the aim of this study was to determine the effect of different seeding rates on the grain yield and quality of three bread wheat cultivars.…”
