A Front Line Demonstrations
(FLD) study on cotton for 2005-06 recently released by the
Indian Council of Agricultural
Research (ICAR) reconfirms a net 33.7% increase in seed
yield of Bt cotton hybrids over non-Bt hybrids and 73.8%
increase over open-pollinated cotton varieties (OPV). Data in
the study came from 1,200 demonstration and farmers plots in 11
cotton growing states in India.
In the demonstration plots, the
Bt cotton hybrids proved to be highly productive with an average
yield of 2,329 kg/ha of seed cotton compared to the non-Bt
cotton hybrids (1,742 kg/ha) and varieties (1,340 kg/ha).
Similarly, the average yield of Bt cotton hybrids was higher in
farmers’ plots at 1,783 kg/ha compared to non-Bt cotton hybrids
(1,362 kg/ha) and OPV in farmers' field (1,072kg/ha).

The FLD study of cotton was
conducted by the Division of Agricultural Extension of the ICAR,
in collaboration with various stakeholders under the Mini
Mission-II of the Technology Mission on Cotton (TMC).
A copy of the study "Front Line Demonstrations on Cotton
2005-06" is available on request from the Division of
