An Experiment carried out in one of the farmers' fields in Gbalah region, located 35 km northeast of the city of Hilla during the spring 2014 season by using split-split phot arrangement in accordance with randomized complete block the design and RCBD with three replications.

The results showed superiority Cultivar (V1) was significant for prescription fertility rate, the number of seeds / disk and holds the overall superiority of seeds while Cultivar (V2) in the recipe seed weight of 1000, the proportion of oil.

Samadhi (N3), significantly studied the proportion of fertile qualities, number of seeds / disk, seed weight of 1000, the sum total seeds and holds oil recipe except oil ratio has excelled at the level of Samadhi (N1).

And the superiority of the date (D2) in the recipe and the proportion of fertile seeds, while the total sum deadline superiority( D1) in Recipe percentage of oil in the seed.

As for the study interactions between factors outperformed combination (V1 × N3) in the recipe holds overall seed and holds the oil while the overlap outweigh (V2 × N3) in the prescription weight of 1000 seeds.

As well as the superiority of overlap (D1 × V1) in the recipe number of seeds / tablet while outweigh the overlap (D2 × V1) in the recipe holds overall seed, holds the oil.

And gave the combination( N3 x D1) outweigh the recipe number of seeds / tablet combination gave while( N3 x D2) exceeds the total winning recipe for seeds.
