In order to Determination of the planting date to achieve maximum yield in common millet forage cultivars "selected from experiments 2005 and 2006 years," this research layed out as a splitplot design based on randomized completely block design with three replications and two years. planting dates including(22 May, 5 june, 22june and 6 july) as the main plots and cultivars selected from 2 years were as sub-plots. characteristics such as tiller number, leaf number, plant height, length of panicle, stem diameter, 1000seed weight and forage yield were measured Then a combined analysis of variance using MSTAT-C software and comparison with multiple range test was performed. according to the results of these research grain yield was beter in2nd and 3rd planting date, forage yield was better in first planting date than other planting dates, also Kfm5 promising cultivar was better about grain and forage yield than other cultivars.
