Identification of a suitable cultivation method with low energy use, GWP and high productivity is the
need of the hour. A 16-year old field study in the Indo-Gangetic Plains (IGP) with different methods of
rice cultivation viz., zero tillage (ZT), happy turbo seeder (HTS), bed planting (BP), reduced tillage (RT),
conventional sowing (CS), direct sowing (DS), broadcast method of sowing (BS), manual transplanting
(HT) and selected transplanting methods like, manual transplanter (MT) and mechanical transplanter
(MaT) was used to evaluate the energy input and GWP. HT method of rice cultivation recorded higher
energy use than ZT, HTS, BP, RT, CS, DS and BS methods, respectively. Whereas HTS method recorded
highest net grain energy (NEg) and this was followed by ZT and MaT, The PTR method recorded 61e66%
higher GWP compared with direct sown unpuddled method of rice cultivation. Among direct sown
unpuddled methods of rice cultivation, HTS, BP, RT and ZT had lower GWP than farmers' practice. MaT
recorded higher carbon output than ZT, HTS, BP, RT, CS, DS and BS methods. The study indicated that
direct seeded method of rice cultivation is energy efficient with lower GWP and thus may be
recommended.
