Analysis of productivity growth in agriculture J. Agric. Res., 2010, 48(1) 93 DECADEWISE ANALYSIS OF TOTAL FACTOR PRODUCTIVITY GROWTH OF AGRICULTURE SECTOR IN PUNJAB, PAKISTAN: 1970-2005* Nasir Nadeem**, Muhammad Siddique Javed***, Sarfraz Hassan**** and Sultan Ali Adil***** ABSTRACT A study was conducted in the Department of Agricultural Economics, University of Agriculture, Faisalabad, Pakistan during 2008 to analyze overtime productivity growth and changes in growth pattern in Punjab’s agriculture. Input, output and total factor productivity (TFP) growth indices were estimated for agriculture for a period 1970 to 2005. For this purpose widely used index number approach namely Tornqvist Theil approximation to devisia index was employed. The results revealed that annual average growth rate of input, output and TFP indices remained 1.46, 3.49 and 2.0, respectively for the whole study period and TFP contributed 57 percent towards output growth. The decadewise results indicated that TFP growth remained maximum during 1980s. KEYWORDS: Land productivity; input output analysis; Punjab, Pakistan. INTRODUCTION The overall rate of economic growth of a country like Pakistan largely depends upon the performance of agriculture sector. Whatever happens to agriculture is bound to affect the growth of country (15). The past experience shows that periods of high or low agricultural growth have generally matched with the periods of robust/poor performance of the national economy (2). Increasing population growth especially in developing countries, limited possibilities of further extension of cultivated land, conversion of fertile land to residential and industrial areas (11), increasing resource degradation (28), wide gap between potential and national average yield (23), slow down of cereal production due to declining world prices and over-intensification of cereal production since 1980 in developing countries (30) and increasing *A part of Ph.
