Abstract
Adoption of HYV of wheat, rice, maize and bajra, have ultimately play a key role in agricultural development. The introduction of modern agricultural technology since 1960s shown a positive impact on crop production. Inpite of the fact that as the new agricultural technology flourished by the use of assured irrigation, chemical fertilizers, pesticides and insecticides, advanced agricultural machineries and soil conservation measures it also creates some environmental problems such as the reduction of area under forests and pasture lands, salinization, lowering of underground water table soil, water and air pollution, reduction in biodiversity, decline in soil fertility, silting of rivers and emergence of several diseases and health hazards. For these ananlysis, 1996-2000 and 2001-2005 data have been considered based on secondary sources and my Ph.D thesis work. To compute the crop productivity indices there are Crop Yield Index, and Standard Nutrition Unit (SNU) have been applied. The influence of agricultural inputs was examined by applying Karl Pearson’s coefficient of correlation techniques in an attempt to establish the causative factors to ascertain variations in the districts of the state.
