Evaluation of Forage Yield and Quality of Intercropping of Vetch and Grasspea with Grasses Annual under Rainfed Conditions in Markazi province.

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 ١٣٨٧-٨٨ and ١٣٨٨-٨٩ 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 ١٦ treatments, including pure culture vetch (Vicia Panonica), grasspea (Lathyrus Sativus) with a density of ٢٥٠ seeds per square meter and annual grasses includes triticale and annual lolium (Lolium multiflorium) with a density of ٤٠٠ seeds per square meter and the ratios of various intercropping they contain legumes٧٥% + Grass٢٥%, legumes ٥٠% + Grass ٥٠%, legumes ٢٥% + Grass ٧٥% 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 ٥٠% 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 ٩٩% confidence was significant difference. In comparing the mean treatments for wet forage, intercropping treatments ٩(vetch٥٠% + triticale٥٠%), ١١(grasspea٥٠% + triticale٥٠%), ٧(grasspea٢٥% + triticale٧٥%), ١٣(vetch ٧٥% + triticale٢٥%), ٥(vetch٢٥% + triticale٧٥%) and ١٥(grasspea٧٥% + triticale٢٥%), respectively, with ١٦,٥٨٠ to ١٥,٣٣٦ kg per hectare and no significant difference had the highest yield and for dry forage, intercropping treatments ٩, ٧, ١١, ٥, ١٣ and ١٥ ,respectively, with ٥٦١٥ to ٤٦٩٣ kg per ha, had the highest yield. Protein yield treatment grasspea٢٥% + triticale٧٥% with ٨٠٥ kg per hectare the highest yield and intercropping treatments, respectively ١١, ٩, ١٥, ١٣ and ٥ 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 grasspea٥٠% with triticale٥٠% and grasspea٢٥% with triticale٧٥% 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.
