Abstract: Transgenic stacked maize hybrid was developed for preventing yield losses of maize crop to improve productivity. In this view, the field experiments were conducted to study the carry over effect of glyphosate K salt applied in preceding transgenic stacked maize hybrids (Mon 89034X NK 603) in succeeding green gram in the experimental site of Tamil Nadu Agricultural University, Coimbatore during kharif, 2009 and rabi, 2009-10. Glyphosate was applied as post emergence at 900, 1800 and 3600 g a.e ha-1 in Hishell and 900 M Gold transgenic maize hybrids and it was compared with non-transgenic counterparts with pre-emergence application of atrazine at 0.5 kg/ha followed by HW on 40 DAS. Succeeding green gram crop was sown immediately after the harvest of herbicide tolerant transgenic stacked maize hybrids. Observations like germination percentage, visual phytotoxicity, plant height, total weed density, dry matter production and yield were recorded. The final results revealed that, both post emergence application of glyphosate and pre-emergence application of atrazine did not have any residual effect on succeeding crop.
