In the present study Haryana state has been divided into two Agro-dimatic zones i.e. eastern zone and westerh zone. The required data for this study (1966–67 to 1998–99) were taken from various issues of Statistical Abstract of Haryana. The Compound Growth Rates (CGR) and trends of area, production and productivity were worked out for all the three periods 1966–67 to 76–77; 1977–78 to 1988–89 and 1988–89 to 1998–99 respectively and for both the zones and different forms of models were fitted. The analysis indicated that the area, production and productivity of wheat crop have increased significantly - through 1966–67 to 1998–99. The improvement in the yield will be helpful for further Increasing the area of wheat in the state.
