بررسی اثر زمان های مختلف برداشت گلچه بر عملکرد گل، دانه و روغن دو رقم گلرنگ در منطقه سیستان

In order to study of time effects and floweret delete on grain yield oil and flower used from two red flowers and spineless (K.H.W.39,1I 111) in main plot and three halvest date as subplot in this study used from split plot design on loase of remdomized complete block design with 4. replications with longth of flowering period of winter carthamus is near 30-35 days, the harvesting date floweret was 366 and, day from the start of flowering till terminate flowering each plot include 12 lines with 6 meters longth and so spaces and inside of Jines, plant distances was to and characters height, head number, seed number in head and were evaluated. For determining of yield ten plant as randomly were selected and all characters on base of this evaluated. For evaluation of oil percent 40 gr seed send to oil seeds research department. Results showed grain and floweret yield don't has significant differences as K.W.IL.39 3 days after floweret harnest with 3269.25 kglha has the most yield and after 3 from after flowering has the 444.174 kg/ha harvest key words: carthamus, grain yield, oil, floweret.
