Abstract :
In order to investigate the effects of fertilizer sources and intercropping ratio on elements concentration in forage of fennel and sainfoin plants, a split plot experiment was conducted as randomized complete block design with three replications at Shahrekord University research farm during the 2015 and 2016. Five fertilizer sources (manure fertilizer 100%, chemical 25%+ manure 75%, chemical 50%+ manure 50%, chemical 75%+ manure 25%, chemical fertilizer 100%), and sole cropping of fennel (F), and sole cropping of sainfoin (S), and three intercropping ratio (include fennel 75%+ sainfoin25%, fennel 50%+ sainfoin 50% and fennel 25%+ sainfoin 75%) were also considered. The results showed that the highest nitrogen, phosphorus and potassium, and iron, manganese and copper concentrations were related to the chemical fertilizer in both fennel and sainfoin plants. The highest potassium concentration of fennel in both years was related to chemical fertilizer with 31.4 mg g-1 in 25% fennel + 75% of sainfoin, and increased by15% in the first year and 10% in the second year as compared to 100% manure fertilizer treatment. Also, the highest nitrogen concentration of sainfoin in the first and second years was related to the monocropping of sainfoin under chemical fertilizer with 38.5 and 39.9 mg g-1, respectively. Therefore, it can be concluded that the chemical fertilizer alone or the combination of manure with chemical fertilizer due to the gradual mineralization of the elements, access to and more of the elements required by the plant in monocropping and intercropping can be play an important role in the absorption and nutrition concentration of plant and increase yield.
