Abstract
The main goal of this study was to investigate the way of affecting
of water in production of cucumber. From aspect of
econometrics, mutual relationships of production function and
expenses have been analysed in which Translog cost function
has been used. This function has been estimated using the conditional
input demand functions, the shefard theorem, chemical
fertilizer, animal fertilizer, labour force, seed, and pesticide in
the framework of a system of equations by taking advantage of
the irrelevant regression method. Applied inputs is for 151
cucumber Beneficiaries in Khash in farming year of 2011-12
that insider and crossing tendency of input demand for this
product has been investigated through collecting questionnaires
and using obtained coefficients. The results show that the translog
cost model is a good fit compared to the data of research.
According to the reviews, demand for water has a minor Insidersuccession
tendency more than one which shows possible stretch
of demand function rather than the price of the inputs. Hence,
appropriate pricing policies can be used to take a positive step in
preventing the extreme usage of this input and directing beneficiaries
for optimum use of these inputs.
