There is a close relationship among agriculture, economics,
energy and the environment. A comparison was made between
conventional and the system of rice intensification (SRI) methods of rice cultivation by conducting two experiments. One field
experiment was conducted from 2013 to 2017 at 25 locations
across India under the All India Coordinated Rice Improvement
Project and another experiment was conducted in 2017 using
surveys by collecting data from 262 randomly selected SRI farmers using a personal interview method in the Telangana state of
India. The 5-year experimental data revealed that the SRI
method of cultivation produced higher rice grain yield (up to
55%) compared to the conventional transplanting method.
Survey data revealed that total costs of rice production reduced
by 22.71% under SRI. Break even output under SRI was reduced
by 58.1%. Adoption of SRI saved total energy inputs by 4350 MJ/
ha. The energy productivities were 0.16 kg/MJ and 0.21 kg/MJ
for conventional and SRI methods, respectively. Also, SRI
resulted the lowest greenhouse gas emissions of 0.280 kg CO2
e/kg rice grain. Therefore, for ensuring higher productivity, net
returns, energy efficiency and sustainable rice production it is
recommended to adopt an environmentally friendly SRI method
of crop establishment in the Telangana region of India.
