Estimation of the Production Function of some (Modern) Wheat Cultivars in Salah Al-Din Governorate for the Agricultural Season (2020-2021)

Abstract

The study aims to measure the effect of using modern varieties on increasing the productivity of a dunum of wheat crop, and to study the economic impact of cultivar change on the transmission of the supply function of the wheat crop, and to determine the amount of increase in production by replacing high-producing varieties with low-yielding varieties, and the study used Harry’s model Ir_Edward Shaw in estimating the transfer coefficients in the resulting supply of the different varieties of the wheat crop for the districts and sub-districts of Salah al-Din Governorate (Tikrit, Samarra, Al-Alam, Al-Dur), according to a questionnaire form, where the sample size included (160) farmers for the wheat crop, as it was found that the use of modern technologies led to shift the supply function to the right by (1.192 ‘1.510 ’ 1.351) % respectively, which means an increase in the quantity supplied of wheat and the trend towards self-sufficiency of this crop, and from the estimation of the joint production function for farms applied to modern technologies, the results of the imaginary variable parameter (X8) became clear. Its value was (0.811) and its sign was positive and it is significant at the level of (1%), and this means that the use of modern technologies has a positive effect by raising the productivity of farms applying modern technologies.
