بررسی و مقایسه عملکرد کمی و کیفی کشت مخلوط ماشک و خلر با گراسهای یکساله در شرایط دیم استان مرکزی

To evaluate and compare the quantitative and qualitative yield of vetch and grasspea intercropping with annual Grasses under rainfed conditions of Markazi Province, an experiment during - and - Farm Research Station Dryland Agriculture and Natural Resources Research Center of Markazi Province, located in region the Frahan, Tafresh city and as a randomized complete block design with three replications. Treatments to treatments, including pure culture vetch (Vicia Panonica), grasspea (Lathyrus Sativus) with a density of seeds per square meter and annual grasses includes triticale and annual lolium (Lolium multiflorium) with a density of seeds per square meter and the ratios of various intercropping they contain legumes % + Grass %, legumes % + Grass %, legumes % + Grass % to replace and tangled were applied. Traits including both wet and dry forage yield and protein yield of forage were measured. Harvesting wet forage was % flowering stage legumes with dough stage of grain the grass. Statistical analysis on data using SAS software was performed. The results of analysis of variance combined data measured showed that between crop years, treatments and year * treatment interaction for wet forage yield, dry forage yield and forage protein with % confidence was significant difference. In comparing the mean treatments for wet forage, intercropping treatments (vetch % + triticale %), (grasspea % + triticale %), (grasspea % + triticale %), (vetch % + triticale %), (vetch % + triticale %) and (grasspea % + triticale %), respectively, with , to , kg per hectare and no significant difference had the highest yield and for dry forage, intercropping treatments , , , , and ,respectively, with to kg per ha, had the highest yield. Protein yield treatment grasspea % + triticale % with kg per hectare the highest yield and intercropping treatments, respectively , , , and are the next category. Land Eqivalent Ratio (LER) the intercropping treatments are larger than the unit. According to the results obtained is observed that intercropping treatments vetch and grasspea with triticale had the highest wet and dry forage yield and protein.Among these, intercropping vetch and grasspea % with triticale % and grasspea % with triticale % are superior to others. Overall, this study is concluded that with intercropping vetch and grasspea with triticale in above ratios can produce considerable forage in terms of quantity as well as quality which could be suitable alternative for fallow after wheat in region drylands. Key words: intercropping, legume, triticale, forage yield
