Monsanto study says crop in four Gujarat districts showed susceptibility to pest
The Genetic Engineering Approval Committee (GEAC) is learnt to have received a report confirming pink bollworm developing resistance to Bt cotton in four districts in Gujarat. The apex regulator of genetically modified (GM) crops is likely to consider these findings by Monsanto and Mahyco scientists in its next meeting.
A low-cost free-air carbon dioxide enrichment (FACE) system has been developed at the Indian Agricultural Research Institute, for assessing the climate change impacts on crops. In the FACE system, the supply and monitoring of CO2 is regulated by the computer-based SCADA system. Carbon dioxide concentration recorded at 5 min intervals varied from 507 to 559 ppm in an hourly period. Monthly mean values of CO2 concentration inside the ring ranged from 525 to 553 ppm from July to April. Crops grown inside the FACE ring showed increased yield over ambient CO2 condition.
