Relationship between Input Energy Use and Land Productivity in Punjab Agriculture

The present study based on secondary data made attempt to examine energy inputs and agricultural production of major crops in Punjab State. It was observed that all the energy inputs viz., non-commercial energy inputs (direct and indirect) and commercial energy inputs (direct and indirect) showed a significant relationship with land productivity. Direct non-commercial energy input showed the highly significant negative relationship which indicates that this input was already over utilized and any further increase in the use of this input would decrease the land productivity. Indirect non-commercial energy input showed the significant positive relationship with land productivity followed by indirect commercial energy input and direct commercial energy input which indicated that the land productivity could be further increased by increasing the use of these three inputs. The total commercial energy input showed the significant negative relationship with land productivity. It means that any further increase in the use of this input would result in a decrease of land productivity.
