Effects of cattle manure and plant growth promoter bacteria application on some morphological traits and yield in Coriander (Coriandrum sativum L.)

In order to study the effect of organic manure and biofertilizer on some morphological traits and yield in coriander (Coriandrum sativum L.), an experiment was conducted as factorial experiment in the base of randomized complete blocks design with twelve treatments and three replications at homand research station in Damavand of Iran in 2010. The factors were cattle manure in four levels (5, 10, 15 and 20 ton/ha) and plant growth promoter bacteria in three levels (inoculation with azotobacter, inoculation with azospirillum and inoculation together). Besides, these treatments with a control treatment (without fertilizer) were also evaluated using a randomized complete blocks design with thirteen treatments and three replications. Results showed that the highest umbel no./plant, 1000 seed weight, and seed yield were obtained with consumption of 15 ton/ha cattle manure. Plant growth promoter bacteria also showed significant effects on umbel no./plant and seed yield (except 1000 seed weight). The maximum umbel no./plant were obtained with two treatments of inoculation with azotobacter and inoculation with azospirillum and seed yield were obtained with azospirillum inoculation. Interactions between factors on umbel no./plant and 1000 seed weight were significant. Differences between control and other treatments were significant, as umbel no./plant in treatment of 15 ton/ha cattle manure application and inoculation together and also, 1000 seed weight and seed yield in treatment of 20 ton/ha cattle manure application and inoculation with azospirillum were higher than control.
