Effects of harvest time on hay yield and quality of different bitter vetch (Vicia ervilia L.) lines
Özet
This study was carried out in Kayseri Province of Turkey in the years 2011 and 2012 for two years
to determine the effects of harvest time on hay yield and quality of different bitter vetch genotypes.
A total of 16 different bitter vetch (Vicia ervilia L.) lines supplied from EMRI, DATAE and ICARDA
were used as the plant material of the field experiments. Experiments were carried out in randomized
block design with 3 replications. Bitter vetch lines were harvested at flower-set, full-bloom and podset
periods. Green herbage and hay yields, crude protein (CP), protein yield (PY), crude ash (CA),
condensed tannin (CT), acid detergent fiber (ADF) and neutral detergent fiber (NDF) characteristics
were investigated. Results revealed increasing ADF-NDF ratios, green herbage and hay yields and
decreasing crude protein, crude ash and condensed tannin ratios with the progression of harvest
time. Pod-set period was determined as the proper harvest time. The lines VE-16, VE-5, VE-1, VE-2
and VE-6 were considered as primary lines to be used in further breeding research and agricultural
activities of the region with regard to hay yield and quality.
