ANALYSIS OF ENERGY INPUTS AND OUTPUTS IN PAKISTAN AGRICULTURE – PART II

Abstract

This study investigated the pattern of energy consumption and its relationship with crop production in Pakistan from 1981-82 to 2005-06. Output was a function of physical, seed and fertilizer energies in this study. Whereas physical energy included human labour, animal power, electricity, petroleum and tractor manufacturing and repair energy. The total physical energy increased from 7 GJ/ha in 1981-82 to 10 GJ/ha in 2005-06. The total energy (physical +seed + fertilizer) also increased from 14 GJ/ha in 1981-82 to 23 GJ/ha in 2005-06. Although, energy efficiency ratio fluctuated with overall marginal decrease during this period, these results revealed that fertilizer and seed energy in general and nitrogenous fertilizer energy in particular contributed significantly to output.
