“…The index is a weighted sum of all input and output indices, the input-output included land, labor, capital stalk, chemical fertilizer conventional agricultural inputs, and the index generally includes land, labor, and physical and human capital. Many of the studies have been conducted in Pakistan, India, and other regions of the world in which total factor productivity index has been used to get the true level of productivity of the agriculture sector by employing various approaches like Wizarat (1981), used arithmetic index approach to get TFPc results using data from 1953 to 1979, rose Rosegrant and Evenson (1993), Saleem et al (2019), Sarel and Robinson (1997) Cornejo and Shumway (1997), Shabbir (2015Shabbir ( , 2016, Antle and Capalbo (1988), Jin et al (2002), Ali and Byerlee (2000), Coelli and Rao (2003), Mukherjee and Kuroda (2003), Ali (2004), and used Tornqvist-Theil Index approach, to get TFPC results. However, Wizarat (1981)'s study has many shortcomings such as non-availability of data, and perfect substitutability between inputs which make her analysis incomplete.…”
