The objective of this research was to examine the concentrations of crude protein, P, K, Mg, Fe, Mn and Zn of 5 triticale genotypes and 2 barley cultivars (two-row) at different growth stages. The experiments were carried out at Süleyman Demirel University farm in Isparta during the growing season of 2012-2013. Three hexaploid triticale lines (SDÜ-21, SDÜ-27, SDÜ-43) and 2 cultivars (Karma-2000 and Tatlıcak-97), and two-row barley cultivars (Hamidiye and Cumhuriyet) were used in the experiment. The experimental design was a randomized split block design with three replication. The genotypes were used as main plots and growth stage were used as sub-plots. The basic pre-sowing fertilization rates for all plots were 30 kg N·ha-1 and 50 kg P·ha-1, the rest of 30 kg N·ha-1 was applied at the early spring (stem-elongation stage). Plants were harvested at four stages, stem elongation, milk development, dough development and mature stage. Samples taken from each plot were dried to constant weight at 65°C in oven. After cooling, the samples were milled for crude protein and mineral element analyses. According to the results of variance analysis, the nutrient concentrations of triticale and barley genotypes showed variations depending on the genotypes and different growth stages. The ...
This study was conducted during the 2020-2021 growing season at the experimental field of the Department of Field Crops, Faculty of Agriculture, Kahramanmaraş Sütçü İmam University. The objective was to evaluate the adaptation, herbage yield, and forage quality of selected barley (Hordeum vulgare L.) varieties under the ecological conditions of Kahramanmaraş province. Ten barley cultivars (Compagne, Ibaona, Arconda, Yalın, Çetin 2000, Asil, Aydan Hanım, Bozlak, Misket, and Akar) were used in the experiment. The experiment was arranged in a randomized complete block design (RCBD) with three replications. The results revealed no statistically significant differences among the varieties for the traits evaluated, except for crude ash content. Green herbage yield ranged from 1046 to 1506 kg/da, while dry herbage yield varied between 334 and 484 kg/da. Dry matter content ranged from 29.66% to 33.30%, crude protein content from 11.9% to 14.0%, and crude ash content from 6.48% to 8.67%. Neutral detergent fiber (NDF) and acid detergent fiber (ADF) ratios ranged from 62.30% to 68.17% and 32.05% to 36.58%, respectively. Digestible dry matter (DDM) values ranged from 59.58% to 64.42%, dry matter intake (DMI) from 1.76% to 1.93%, and relative feed value (RFV) from 83.28 to 95.34. Among the cultivars, Compagne had ...
