ABSTRACT

Most public sector cotton variety trials are conducted to determine the genetic potential of each entry; hence, all varieties are produced with the same management and with a goal of producing maximum yields. Transgenic varieties have provided new tools for pest management but raised concerns about the relative performance of these varieties compared to conventional re-current parent varieties and the relative profitability of the technology systems compared to conventional management. This five year study was conducted to compare yield and economics of transgenic and conventional varieties in the respective technology systems.
