GRAIN YIELD AND NUTRITIONAL QUALITY OF DIFFERENT RYE GENOTYPES

Ugur BASARAN, Erdem GULUMSER, Yusuf Murat KARDES, Medine COPUR DOGRUSOZ, Hanife MUT

Abstract

Rye (Secale cereale L.) has a high tolerance to cold, drought, diseases and pests. Besides, rye improves soil structure, builds organic matter and helps protect again water and wind erosion. The aim of this study was to determine the grain yield and quality of rye as feed in Central Anatolian conditions. For this purpose, nine landrace and one variety (Aslım-95) of rye and one variety of triticale (Karma-2000) were investigated for grain yield, crude protein content, acid detergent fiber (ADF), neutral detergent fiber (NDF), potassium, phosphorus, calcium, magnesium, total phenolic, total flavonoid, DPPH free radical scavenging activity and condensed tannin content. Experiments were carried out in Yozgat ecological conditions in 2018-2019 and 2019-2020 growing seasons in a randomized block design with three replications. There were significant (p<0.01) differences between genotypes and years in terms of grain yield and all the nutritional quality traits. According to the quality traits, it was determined that some landraces have better performance than the variety of rye and triticale. As result, it was determined that the landraces have the potential to be used as a genetic resource in breeding studies in terms of yield and quality traits for feed type rye. ><0.01) differences between genotypes and years in terms of grain yield and all the nutritional quality traits.

Effects of Different Water Stress Levels on Biomass Yield and Agronomic Traits of Switchgrass (Panicum virgatum L.) Varieties under Semi-Arid Conditio

Abstract

A field experiment was conducted in the Wielkopolska region at the Gorzyń Research Station, Poland (52.34°N, 15.54°E) in Central Europe. The study was conducted over a 3-year period (2017, 2018, 2019) as a two-factorial design with four replications in the RCBD. The aim of the research was to determine the effect of the cultivar (‘Bolero’, ‘Tytan’) and the inoculation (Nitragina–seeds inoculation, Nitroflora I–seeds inoculation, Nitroflora II–soil inoculation, HiStick® Lupin–seeds inoculation) on plant development, seeds chemical composition and yielding of narrow-leaved lupin. The weather conditions and experimental factors significantly influenced on productivity of narrow-leaved lupin ‘Tytan’. Drought during the growing season reduced seeds and protein yields. After inoculation of HiStck the seeds yield was significantly greater by 12.4% (p < 0.01) and the protein yield after application of Nitroflora I or HiStick by 13.9% (p < 0.01) and 19.2% (p < 0.01), respectively. Correlation coefficients showed strong relations between number of pods and seeds per plant in both cultivars regardless of the inoculation variant, however the strongest relations in both cultivar were proved on HiStick treatment.
