بررسی عملکرد علوفه کشت مخلوط ماشک و خلر با جو در شرایط دیم خاک شور استان گلستان

This investigation was conducted to study the performance of intercropping of two legumes with barley as autumn seeding in rainfed conditions of Golestan province. Seeds of promised line of Vicia dassycarpa cv. No 2446 was mixed with Hordeum vulgar (cv. Sahra) at 75-25, 50-50, 25-75 ratios and pure sowing and also, Lathyrus sativus cv. Zanjan was mixed with Hordeum vulgar (cv. Sahra) at 75-25, 50- 50, 25-75 ratios and pure sowing. The research site was prepared by disk in the early autumn and seeding was in the mid-October after replacement of appropriate fertilizer from N and P sources. Barley and legume seeds were planted on separated rows at each plot. Results showed a high increasing in forage yield at the second year due to increasing in rainfall related to first year (more than 133 mm). Forage yield at 25% grass pea 75% barley mixture was a little more than 50-50 and more than other ratios. Forage yield for hairy vetch with barley showed that 50-50 ratio was a little better than others. Generally, all mixture treatments were produced high protein than pure barley. The hairy vetch-barley (75-25) and grass pea barley (50-50) in terms of protein yield per area were the best treatments.
