The development of any country is a dynamic phenomenon and has to be constantly endeavored. Ever since
India became a sovereign republic, the successive Governments in all the States have been endeavoring for the rapid
economic development. Here in the present study we have studied the technological innovation (TI) of one of the
most fertile and prosperous Indian state, Punjab as a case study. In early sixties the establishment of an Agricultural
University in Punjab paid rich dividends in the shape of green revolution and white revolution. As a result,
agriculture sector got a big boost. The green revolution, the white revolution and blue revolutions helped continued
economic growth of the State, in spite of a decade of turmoil in the recent past.
Once an innovation has been introduced by one industry/firm/or a group of people/or by an individual, how soon do
others adopt it in rural India? What are important factors which determine how rapidly the innovation spreads, what
is the trend to spread rate of TI, these are the important questions for sociologists, economists, scientists, managers,
technocrats & ultimately governments! Keeping this in mind, in this paper we have studied “A Mathematical
modeling approach to study growth rate of grassroots Technological innovations” for prediction of adoption rate of
new innovations among Indian villagers especially who are depending on agriculture only. For the purpose we have
discussed an application of ordinary differential equation to construct a mathematical model to know the spread of
technological innovations in rural India. Here we have predicted the adoption process of TI as sigmoid pattern
growth or almost sigmoid pattern. In support of this, we have taken Punjab (India) as a case study and for the
purpose; we have collected the data regarding technological innovations in farming about:
a) Percentage of area in thousand hectares under high yielding varieties of major food Crops.
b) Consumption of Chemical Fertilizers in Punjab
c) Consumption of Pesticides/Insecticides in Punjab
d) Tractors registered in Punjab
e) Number of Tube wells in Punjab
