Robinson)]]>AhmadiAmir Hossein Agha ChaichiMohammad Reza 8200768The study was conducted to determine the effects of nitrogen fertilizing systems and harvest frequency on dry forage, pod and seed yields of snail medic; Medicago scutellata var. Robinson. Rhizobium meliloti inoculation and four levels of chemical nitrogen fertilizer (0, 25, 75 and 125 kg N ha-1) were allocated to the main plots while four levels of harvest frequencies such as weekly, 2 and 3 weekly intervals and control with only one harvest at 50% flowering were assigned to subplots. According to the results of this experiment, harvest frequency and nitrogen fertilizing systems had significant effects on forage, pod and seed yields of M. scutellata as these traits increased with increment in harvest frequency and availability of nitrogen. Interaction between harvest frequency and nitrogen fertilizer systems was significant for forage and seed yields; hence treatment of 75 kg N ha-1 with 3 week harvest interval produced acceptable forage and seed yields in M. scutellata, which eliminated the necessity of Rhizobium inoculation and reduced the cost and environmental contamination compared to 125 kg N ha-1.]]>Alston, A.M. and R.D.
