    Energetics and techno-economic feasibility of paddy straw management technologies
    (CCSHAU, 2018) Parveen; Jain, Mukesh
    Paddy straw management using different combinations of machinery i.e. T1 = Combine harvester with SMS (CSMS) + Zero till drill, T2 = CSMS + Spatial till drill, T3 = CSMS + Happy seeder, T4 = CSMS + Reversible mould board plough + Rotavator + Seed drill, T5 = CSMS + Rotavator (2 pass) + Seed drill (SD), T6 = CSMS + Disc harrow (3 pass) + Planker + SD, T7 = CSMS + Rotavator + Manual broadcasting + Rotavator, T8 = Traditional combine (TC) + Stubble shaver + Straw baler + Disc harrow (2 pass) + Planker + SD, T9 = TC + Stubble shaver + Hay Rake + Straw baler + Disc harrow (2 pass) + Planker + SD, T10 = TC + Traditional straw removing method + Disc harrow (2 pass) + Planker + SD with the objective of quantifying the energy requirement and to evaluate techno-economic feasibility. From the experiments, it is concluded that the specific energy consumption and unit cost of operation were in the range of 25 to 28 MJ q-1 and 63 to 68 Rs. q-1 for treatment T1, T2 and T3 respectively. Under the treatment T10, the specific energy consumption and unit cost of operation were 38 MJ q-1 and 74 MJ q-1, respectively. Under the treatment T4, T6, T7, and T8 the specific energy consumption was in the range of 50 MJ q-1 and unit cost of operation was in the range of 112-135 Rs. q-1. Highest specific energy consumption (58.15 MJ q-1) in treatment T5 and highest unit cost of operation (140.52 Rs. q-1) was found in treatment T9.
