The negative effect of long-term consumption of chemical fertilizers on the environment and some soil properties have caused the use of organic compounds to be of particular importance. Inorderto investigatethe effectof humic acidand fulvic acidonrapeseed,thisexperimentwasconductedinthe Moghan agriculturalresearchstation during 2018-2019 crop season. The was experimentcarried outin terms of a randomized completeblockdesigninthreetreatments including control, humic acidirrigation and fulvic acid foliar application in three replications.Afterharvest,the datawereanalyzedandthe comparisonof the meanswasdonebytheleastsignificantdifference (LSD) test.The resultsshowedthattheeffectoftreatmentsonthe numberof seedsper pod,strawyield,seedyield andharvestindexwas significant at 0.05level of probability.Application offulvicacid increasedthe seed yield from3333kg/hato3600kg/ha which was significant at 0.05level of probability. The useof humicacidhadincreased the seed yield to3386kg/ha which was not significant at 0.05level of probability with control and fulvic acid treatment.Accordingtotheresult,amongthe growthfactors,the numberof seedsper pod hadthe maximumeffecton the seed yield increase.
