Investigation of Cost and Productivity of per cub water from well from garden and agronomy Products impact of wheat in Fars Province

The objective this study were to investigate Cost and Productivity of per cub water from well for garden and agronomy Products in plain of Fars Province. For the purpose of study, were use purposive sampling and multy stage cluster sampling methods and entire 164 questionaries and were use Residual value and econometrics models. Results of the study reveald that Cost of per cub water from well is 839.3 Rls. Mony productivity of per cub water from well is 3875.4 Rls. and produect productivity of per cub water for weath, pop corn, vegetable and citrus fruits are 0.56, 0.52, 3.2 and 1.4 kg., respectively. The Results of transcendental and Cob-Douglas production functions for weath showed that value of marginal product of per cub water were Calculated 280 and 310 Rls respectively. Calculates of marginal productivity and water price displayed that producers use more over water input. Therefore in programming crop pattern recommended that indices of productivity of water consumers considered.
