Abstract

Sunflower is planted in about 2000 hectares of Isfahan Province areas every year and most of these areas are in the country of Isfahan specially Mahyar area. Sunflower is usually planted as second cropping after end of irrigation or harvesting of cereals, in summer. There are some farmers that they get more than 2.5-3 t/ha YIELD but sunflower YIELD is low in some fields and it was caused to decrease of planted areas in recent years. This study conducted during 1378 to 1380 to evaluation limited factors of sunflower YIELD in this area, Some fields were selected every year and information about their soil, method of planting, Keeping and harvesting were collected. In addition, plant samples were selected at flowering stage from fields every year and some plant parameters were measured as their vegetative growth condition, this information were analyzed descriptively and statistically. Results showed that presentation of honey bee hives in field, head diameter of plants, irrigation times, using of herbicides, number of leaves per plant, planting date and using of land leveler, significantly correlated with sunflower YIELD and they entered to YIELD model, respectively. On the whole, R_square was %76 in this model. In the middle of this factors, using of herbicides had negatively and the others had positively related.
