“…We need to multiply marginal productivity by the output market price to obtain the monetary value of non‐marketed input (Grammatikopoulou et al, 2019). The general form of production function is defined as follows: where Y is the production amount of the agriculture commodity, X j is use of production input j , β is function parameters and ɛ i is coefficient of random error (Alropy et al, 2019). There are 20 functional forms of Leontief, Linear, Quadratic, Cubic, Generalized Leontief, Square root, Logarithmic, Mitscherlich, Spillman, Cobb‐Douglas, Generalized Cobb‐Douglas, Trascendental, Resistance, Modified Resistance, CES, Translog, Generalized Quadratic, Generalized Power, Generalized Box‐Cox and Augmented Fourier.…”
