Cropping systems in farmland areas of iran are characterized by consumption of chemical fertilizers (c)leading to serious erosion and fertility decline. information regarding the influence of organic organicfertilizers (oh) and c on pumpkin traits is not available. therefore, a field experiment was conducted atresearch farm of kurdistan university in 2009. fourteen compositions of bio, o and c were done.treatments. the results indicated that the maximum seed yield (118.5 g m - 2), the oil yield (43.31 g m - 2) and fruityield (6056.2 g (m - 1) were obtained with treatment that pumpkin seeds inoculated with free - livingnitrogen than bacteria (no) and phosphate solubilizing bacteria (po) + 50% organic fertilizer. oilwhile loyal to fertilizer treatments and the maximum oil percentage (48.15%) was obtained attreatment and pumpkin seeds inoculated with psb + 50% chemical fertilizer. the fertilizer treatmentshad no significant effects on the 1000 seeds weight and fruit number per plant. it is concluded thatapplication of biofertilizers with 50% of chemical and organic fertilizers (co), reduced the need for c andproduced higher oil, seed and fruit yield.
