Abstract
The study was conducted with the aim to determine the impact of soil quality on the Bt cotton productivity. A sample of 150 farmers was selected by using multi-stage sampling technique from three districts i.e. Rahim Yar Khan, Multan and Mianwali. A Cobb Douglas production function was employed to assess the effect of various agronomic and demographic variables on the Bt cotton productivity. Results of the analysis indicated that land preparation cost, seed cost, fertilizer cost, labour cost and dummy variable of soil quality were significant and positively contributing towards higher Bt cotton yield. While the spray cost and irrigation cost variable were found positive but non-significant. Findings of the study suggested that focusing on maintaining and improving the quality of soils is necessary to obtain higher crop yields. All this needs attention of agricultural extension department to provide information about advance techniques to farmers for improving soil quality.
