The research aims to estimate the technical and specialized efficiency and the economic efficiency of wheat crop varieties according to the data envelope analysis
method (DEA) and according to the varieties in the research sample, which are
(Bura, Adana, Iba 99), and the data was obtained by designing a questionnaire using the random sampling method for farms in the field. It determined the size of
the samples for the studied items according to their percentage in the community
for (150) farms by (50 for each item in the research sample. The results of the
efficiency analysis were obtained according to the data envelope for production
functions and costs with stability and change in capacity returns. The results of the
analysis showed, depending on the variables of the production function, The results
showed that the farms that achieved full efficiency (100%) were (11) farms, which
were divided into (3) farms for the (Bura) variety, (6) farms for the (Adena) variety,
and (2) farms for the (Ibaa 99) variety. These farms can be counted. References to
the sample farms that did not reach full efficiency and the number of farms that
achieved 100% efficiency in light of the change in yield were (18) farms, divided
(6) farms for the (Bura) variety, (8) farms for the (Adena) and (4) farms for the
variety (Ibaa 99), respectively, while the number of farms that did not reach 100%
efficiency in light of the change in the field Lead (44, 42, 46) farms for varieties
(Bura, Adana, Ibaa 99), respectively. Depending on the variables of the cost function, it turns out that the total of the farms that achieved 100% allocative efficiency
(6) farms with one farm for the Pura variety (4) farms for the variety below and
one farm for the Ibaa 99 variety. In this case, these farms do not have any surplus
inputs because they consume all inputs. The optimum size to reach the optimum
production and the results of estimating the economic efficiency of the wheat crop
and the studied varieties were also shown, as the average economic efficiency was
(0.51, 0.44, 0.41) for varieties (Bura, Aden, Iba 99), respectively. This level is low,
which is the result of the product of each From technical efficiency and allocative
efficiency, which shows that these farms can reduce costs by (49%, 56%, and 59%)
and achieve the same production level or that these farms can get the current production using (51%, 44%, 41%) of resources to become economically efficient. In
light of the results that have been reached, the research recommended encouraging
farmers to use the seeds of modern varieties with high production to make the best

use of agricultural areas in order to give the best production in addition to benefiting from the efficiency indicators obtained through the data envelope model, and
the need to activate the role of the agricultural extension system in alerting farmers
to the use of modern agricultural methods in line with the technical progress in this
field, especially in the countries of the world.
