Özet:

The research was carried out in 2014 and 2015 years in order to determination of straw quality of some grasspea genotypes. In the research; 31 different grasspea genotypes were used as plant material. The experiment was set up in a randomized block design with three replications. In the research; the characteristics such as raw ash ratio, crude protein ratio and yield, acid detergent fiber (ADF), neutral detergent fiber (NDF), digestible dry matter (DDM) and dry matter intake (DMI) ratios, relative feed value (RFV), digestible energy (DE) and metabolic energy (ME) of the straw of the grasspea genotypes harvested for the purpose of seed were investigated. In both years of the research; statistically significant differences were detected between genotypes in terms of all traits examined. According to the result of two years of research; it was determined that the crude ash ratio of straws belonging to the grasspea genotypes varied between 7.12-9.52%, the crude protein ratio between 4.71-7.36%, the crude protein yield between 6.03-11.90 kg da-1, ADF ratio between 39.73-47.42%, NDF ratio between 50.53-62.66%, DDM ratio between 51.96-57.95%, DMI ratio between 1.92-2.38%, RFV between 77.46-106.47, DE value between 2.49-2.75 Mcal kg-1 and ME value between 2.05-2.26 Mcal kg-1. According to the results of the research, it has been determined that Biflorus and Eren grasspea genotypes are superior to other genotypes for straw quality in Elazig and similar ecologies, and it can be recommended to be grown in such ecologies.
