Abstract EN

A field experiment has been carried out in the field of experiments of the forest project of Kut during the period 2010 and 2011 season to compare the growth and yield of sesame varieties and the impact of adding potassium .

Follow the complete randomized block design dissident plot include three replicates the main plot ( Ishtar , Babylon , Rafedeen , Local),varieties while the sup plot include the addition of K2SO4 levels (zero , 100, 200 kg / h ) .

The results show cultivar surpass Rafedeen I n the average characteristics of plant height and weight of 1000 seeds long the first packet from the Earth to the seasonal succession, and the superiority of variety Ishtar in the characteristic of the number of packet in the stem president and yield plant and total yield the proportion of oil and yield oil for seasonal respectively it gives the highest mean yield oil 1351.56 and 1344.32 t /h as local cultivar surpasses characteristic of the number of packet in fruiting branches and the number of fruiting branches of two seasons respectively.

The gives treatment (200 kg / ha) of K2SO4 highest rate of prescriptions of the number of packet in the stem president and branches of fruiting and yield plant and total yield and highest rate of yield plant height and weight of 1000 seeds and oil content and yield oil .

A combination ( Ishtar variety with treatment 200 kg/ h of K2SO4 ) records the highest rate of the total yield to 619.00 and 611.67 kg / d for seasonal respectively, which is reflected on the quotient by giving it the highest rate of oil yield to 354.64 and 350.09kg/d seasonal sequentially .
