Legumes-triticale intercrops, triticale, vetch, pea, forage quality


In order to investigate forage yield and quality of vetch-triticale and pea-triticale intercrops, two years study was carried out at two locations under rainfed Moroccan conditions, considering three seeding ratios (25:75, 50:50 and 75:25). Results showed that intercrops yielded 46 and 52% higher than vetch and pea monocrops, while they produced 16 and 24% lower than sole triticale. Vetch-triticale intercrops out-yielded pea-triticale mixture by 11% in both locations. Within legume-triticale intercrops, forage yield increase when vetch and pea represented 25 and 50% of seeding ratios; and decreased when the legume ratio increased to 75%. The relative yield of individual species and mixtures increased when legume ratio increased at sowing. Vetch-triticale intercrops had conflictual relationships at SEA, while pea-triticale intercrops at 50 and 75% of legume ratios, developed beneficial relations at both locations. Furthermore, intercrops affected positively forage quality at higher legumes ratios. Protein yield from vetch-triticale mixtures was significantly higher than that of pea-triticale intercrops. It was increased by 43 and 12% respectively compared to sole triticale. NDF ADF and ADL decreased when legumes proportions increased in the harvested forage. Similar trend was noticed for digestibility, dry matter intake (DMI), total digestible nutrients (TDN) and relative feed value (RFV). All of these quality parameters were improved when legume ratios were beyond 25%.
