A Parikh S Mosley This study estimates fertiliser response of wheat farms in Haryana for 1970-71. Data for three districts, viz, Ambala, Rohtak and Hissar, were made available through IARS Sample Surveys for Assessment of High Yielding Programme. These data permit us to test several other hyptheses regarding fertiliser use and its response pertaining to local and high yielding variety (HYV) crops.
