Abstract

To determine the Response of yield and yield component of SUNFLOWER, cv. Eiroflor to plant density and weeds control methods, an experiment was carried out in Gareziaaddin city, during 2009. This experiment was conducted in factorial design as a base of randomized complete block design with three replications and two factors, included plant density in three levels ( 8, 9.5 and 11 plant per square meter) and weeds control methods with four levels (noncontrol weeds, terifeloralin pre emergence herbicide, nabo-s post emergence herbicide and hand weeding). The results showed that density of 11 plants per square meter with trifloralin pre emergence herbicide method had yield maximum about 741 gr/m2. Minimum yield harvested from density of 9.5 plant with non weeds control method that had yield reduction about 42%. Also harvest index maximum from density of 9.5 plant with TRIFLORALIN HERBICIDE about 41%. But grain number per anthodium maximum was to density of 8 plant and trifeloralin herbicide with 1303. With attention to experiment results, the density of 11 plants and TRIFLORALIN HERBICIDE for yield increase of SUNFLOWER is recommended.
