Abstract
The objective of current study was to determine the effect of different harvest stages and ensiling periods on silage quality of grass pea (Lathyrus sativus L.) grown in the experimental field of Agricultural Application and Research Center of Bozok University during 2016-2017 vegetation period. The plants were harvested at the flowering and seed filling stage, chopped and ensiled in 2 kg special jars. Then, they were stored at 25±2 oC under laboratory condition for 15, 30 and 45 days. In this study; physical observations (color, structure, odour), dry matter, crude protein ratio, crude ash ratio, lactic acid, acetic acid, butyric acid, phosphorus (P), calcium (Ca), magnesium (Mg), zinc (Zn), iron (Fe), manganese (Mn), sulphur (S), boron (B), chromium (Cr), cobalt (Co) and molybdenum (Mo) and ODAP contents were determined. All silage samples determined in the study were in very good and good quality class of silage. The highest lactic acid was determined at 4.05%, while the lowest was 0.85%. Acetic and butyric acid were ranged 0.93-1.82% and 0.10-0.40% respectively. The highest ODAP content was determined at 2.48 mg/g, while the lowest was 0.66 mg/g. For the successful grass pea silage, harvesting at the flowering stage and ensiling for 45 days was the best treatment.
