Abstract
The present study is an attempt to estimate the acreage and yield response functions for major
crops in Haryana within the framework of co integration and error correction model and to compare the
short-run and long-run supply elasticities of major crops. The long-run acreage response to lagged price
was positive and significant in the case of rice, rapeseed-mustard and sugarcane with elasticity values
0.19, 0.22 and 0.29, respectively. In case of other crops except bajra and gram, very low positive but
non significant price elasticities have been observed. In the short-run, lagged price elasticities were
found to be positive for all the crops. However, the positive significant values have been observed in
case of rapeseed-mustard, sugarcane and bajra. The long-run acreage response to lagged year yield was
found to be positive and significant in case of rice, wheat and cotton (Am.) with elasticity values 0.26,
0.18 and 0.29, respectively,. Irrigation elasticity has been observed to be positive for all the crops in the
long-run, while it is positive for all the crops except gram and rapeseed-mustard in the short-run.
However, only wheat and sugarcane are found to be positively and significantly responsive to irrigation
in the long-run as well as short-run. The long- run yield response to price has been observed to be very
low and non-significant in case of all the crops except wheat, rapeseed-mustard and sugarcane. The
yield response to irrigation has been observed to be positive and significant in case of wheat, rapeseedmustard
and cotton (Am.) only.
