Abstract :

In order to evaluate different tillage systems and fertilizer types on grain yield and yield components on rapeseed, an experiment was done on the farm of Moghan Agro-industry Company in 1399-1400. This experiment was performed in a completely randomized with three replications. Tillage as the main factor in three levels (conventional, low tillage and no tillage), type of fertilizer as a secondary factor in two levels (animal manure 5t/ha and ammonium phosphate fertilizer 500 kg/ha and the cultivar tested to title of sub-factor was considered at two levels (Neptune and Barley). Main, number of pods per plant, number of seeds per pod, 1000-seed weight and grain yield at 1% probability level and grain yield in fertilizer type were 5%. The highest average grain yield was 5 tons / ha and the lowest It was obtained without tillage and ammonium phosphate fertilizer (500 kg / ha). 1 and 5%), number of pods per plant, number of seeds per pod and grain yield were significant at 1% probability level, with the highest mean for low tillage treatment (5 tons of animal manure). R hectares in Neptune cultivar) and animal manure 5 tons per hectare in Neptune cultivar and the lowest average was obtained without tillage (500 g ammonium phosphate fertilizer per hectare in Neptune cultivar) and animal manure 5t/ha in Neptune cultivar. The results of comparing the mean of the three interactions of tillage systems in fertilizer type and cultivar type on yield components showed that the highest mean of low tillage treatment in animal manure of 5t/ha and Neptune cultivar and the lowest average of no tillage treatment in ammonium phosphate fertilizer 500 kg per hectare and Barley cultivar.
