MORPHOLOGICAL AND CHEMICAL CHARACTERS OF Bituminariabituminosa (L) C.H. (Stirtion) GROWN NATURALLY IN THE MIDDLE BLACKSEA REGION

Erdem GULUMSER , Zeki ACAR

Abstract

In this study, morphological and chemical characters were investigated in Bituminaria bituminosa (L.) C.H. Stirtion genotypes collected from 24 different locations Middle Black Sea Region Turkey. The experiment was established in Samsun ecological conditions and carried out for two years (2009-2010). The investigated characters were; plant height, shoot number, main stem diameter, leaflet width and length, leaf number, inflorescence number, flower number per inflorescence, seed width and length, a thousand seed weight, dry matter yield, crude protein content, ADF, NDF, ADP values, ash, Ca, Mg, P, K, Fe, Zn and Mn contents. Only one cut was done in the first year as plant growth was relatively slow. Two cuts were performed in the second year due to greater regrowth ability. Plant height was 88.4 cm in 2009 and, was 80.5 and 74.2 cm for the first and second cutting in 2010 year. Main stem diameter in three cut in both years were recorded as 5.2 cm, 6.3 cm and 3.6 cm, respectively Chemical characters of the genotypes were examined in both leaves and stems, separately. Protein ratios in the leaves were found as 24.30%, 24.60% and 19.61%, respectively, These protein ratios remarkably decreased in the stems; 13.28%, 13.58% and 8.99%.

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

Erdal GONULAL, Suleyman SOYLU, Mehmet SAHIN

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.
