GM crops especially Bt crops are known to have higher resistance to pest attacks. To substantiate this, an experimental study was conducted in 4 different farmlands growing Bt and non Bt-Cotton crops. The farm lands had the same dimensions, fertility and were under similar climatic conditions. The histogram below shows the usage of pesticides on Bt crops and non-Bt crops in these farm lands.

Which of the above 4 farm lands has successfully applied the concepts of biotechnology to show better management practices and use of agrochemicals? If you had to cultivate, which crop would you prefer (Bt or non-Bt) and why?

Explanation

Farm land II requires less application of pesticide. I would prefer Bt crop as it involves no application of fertilizers and pesticides and shows more yield when compared to non Bt crop. Because the use of pesticides is highly reduced for Bt crop. Decrease of pesticide used is also more significant for Bt crop.
