The effect of Zinc sprinkle levels and Different Nitrogen Sources top dressing on seed oil percentage and seed oil yield of Winter Rapeseed

In order to study the effect of different zink levels sprinkle and different nirtrogen sources top dressing on seed oil percentage and seed oil yield of winter Rapeseed Opera in Takestan in 1384-1385 , An experiment carried out in factorial design on the basis of randomized complete blocks with 4 replications that Zink sprinkle amount by the form Zink sulfate in 3 levels 0 , 3/1000 and 5/1000 and different nitrogen sources top dressing uses at early stem elongation and flowering stages in 4 levels ( Urea - Urea, Amunium sulfate -Urea , Urea - Amunium sulfate and Amunium sulfate - Amunium sulfate ) were considered. Effect of Zink sprinkle levels, nitrogen sources top dressing and interaction effects between them on seed oil percentage and seed oil yield had significant effect at %1 level . At this situation application of Zink sulfate concentration 5/1000 with %47/27, Amunium sulfate - Amunium sulfate as top dressing with %46/89 and interaction effect of Amunium sulfate - Amunium sulfate and 5/1000 zink sulfate sprinkle with %47/99 showed maximum seed oil percentage . The results indicated that application of 5/1000 Zink sulfate sprinkle with 1699 Kg/hec , top dressing nitrogen forms Urea - Amunium sulfate with 1661 Kg/hec and interaction effects of mentioned characters with 203 7Kg/ hec gained to maximum seed oil yield .
