Relative performance of low input and high input technology for potato production in India
The energy analysis at CPRS, Jalandhar farm revealed that among the various operations, irrigation consumed the maximum amount of energy, i.e. 6622.12 MJ/ha (44.4%) followed by seedbed preparation 3192.84 MJ/ha (21.4%). Total operation wise energy consumption for potato production was found to be 14...

Zusammenfassung: | The energy analysis at CPRS, Jalandhar farm revealed that among the various operations, irrigation consumed the maximum amount of energy, i.e. 6622.12 MJ/ha (44.4%) followed by seedbed preparation 3192.84 MJ/ha (21.4%). Total operation wise energy consumption for potato production was found to be 14902.77 MJ/ha. Amongst the indirect energy sources, the energy input derived through the seed material was maximum, i.e. 16320 MJ/ha (36.05%). Fertilizer contributed the next major share of energy input, i.e. 10870 MJ/ha (24.01%). The total energy requirement for potato production under mechanized system from all the sources including the direct and indirect sources was 45262.98 MJ/ha. Average output energy from potato was 62983.6 MJ/ha. The output to input energy ratio and average specific energy requirement for the crop was observed to be 1.4 and 2.6 MJ/kg, respectively. |
