Abstract

Garlic is one of the important medicinal plants that it's plants in many origins. The intercropping of plants is a view of sustainable agriculture that it's very useful. To evaluate the potential of Garlic in intercropping with medicinal plants, this study was conducted as a Randomized Complete Block Design (RCBD) with three replications at the Ramin Agriculture and Natural Resources University in 2011-2012. Treatments were includingGarlic intercropping with Psyllium (Plantago ovata), Black Seeds (Nigella sativa), Ajowan (Carum copticum), Fennel (Foeniculum vulgare), Marigold (Callendula officinalis) and Dill (Aniethum graveolens) that planted withthe 50:50 proportion inan interstitial cultureand also, pure culture of above plants. Relative advantage of Garlic intercropping with medicinal plants in terms of Relative Value Total (RVT) was only shown in Garlic intercropping with Black Seeds with 2.04.The most of the amount of increasing actual yield was related to intercropping of Garlic with Psyllium with 1.78. The pure yield of Garlic (7330 kg/ha) and intercropping of Garlic with Ajowan (2300 kg/ha) were the highest and lowest yield, respectively. There was a high significant difference with high correlation between intercrop treatments in terms of the number of bolblet in Garlic. When the number of irrigation (water required plant) increased, Garlic yield was reduced. However, a direct relationship was found between total relative value and number of irrigation. Finally, intercropping of Garlic with Psyllium and Marigold because of the high amount of Actual Yield Total (AYT) is proposed in this region.
