Abstract
An ‘on-farm’ adaptive research study was conducted during 2006-2011 in wet-temperate north-western Himalayas
to evaluate the effects of integrated crop management (ICM) technology on potato tuber productivity, profitability, energy
dynamics and carbon footprints. This ‘On-farm’ field study revealed that the ICM technology imbedded with improved
potato varieties like Kufri Shailja and Kufri Giriraj along with balanced nutrition (120:80:60 kg NPK/ha & 20 t FYM/
ha) and proper crop management and plant protection measures manures, led to higher productivity (27.8%), net returns
(34.5%) and bio-energy production (58.1%) compared to farmers’ practice (FP). The ICM resulted in slightly higher carbon
footprints (0.08 kg CE kg-1 fresh potato tuber yield) compared to FP (0.069 kg CE kg-1 fresh potato tuber yield) due to better
crop management and higher input-use. However, the total carbon output under ICM was ~31.3% higher over FP, indicating
that ICM may prove as a viable mitigation strategy to climate-change. Overall, ICM is a better option over FP w.r.t. potato
productivity, profitability, net-income gains, bio-energy and carbon output in wet-temperate north-western Himalayas.
