Abstract: Abstract This paper attempts to model the positive role of cultivation of genetically modified (GM) crops with its soil-anchoring root characteristic in conservation tillage technology. In a dynamic optimization framework, the farmer produces an optimal combination of a GM and a non-GM variety of the same or of different crops at the steady state, though the steady state is approached most rapidly by producing a single crop. The improvement in the capacity to anchor the soil and an increase in organic matter content in top soil will raise the long-run soil stock under certain conditions. However, the increase in R&D investment and imposition of an input subsidy on GM sector will lead to an increment in area under GM cultivation though their effect on long-run soil stock is uncertain. The empirical validation of the findings suggests that agricultural practices associated with GM crop cultivation will lead to positive growth of the economy.
