Scope and Importance of Straw Reaper Management Machinery
In Agriculture, Haryana is the most advanced state which has the highest intensity of farm mechanization after Punjab. Haryana is the third largest producer of wheat with a total production of 10.1 million tonnes which is 13.27% of the total wheat production of India and ranks first in productivity with an average of 42.32 q/ha. About 50% area of wheat is harvested by combines.
Combine harvesting results in saving time and labor but results in loss of straw (bhusa). This causes the wastage of around 5 million tonnes of straw worth Rs. 1000 crores annually in Haryana alone.
The conventional Combine harvesters leave a considerable amount of long straw and stubbles in the field.
Farmers usually burn them in situ to avoid field operational problems for the next crop. One ton of straw burning releases 3 kg PM10 particulate matter, a total of 60 kg of CO, 1460 kg of CO2, . ,.
The burning of leftover straws not only leads to environmental pollution but also causes a considerable economic loss of precious biomass.
The retrieval of straw from combined harvested rice-wheat fields is done either by straw reaper or straw baler.
We used the straw and stubble left by the grain combined and cut it into small straw and stubble. The straw is cut into pieces and passed through the concave. We use a reciprocating cutter bar for reaping the cut standing stalks.
A straw reaper consists of four main units: stubble cutting and collecting unit, feeding unit, straw bruising unit and “BHUSA” blowing unit. The serrated saw-type cylinder is mostly used in straw combines for bruising. I found Serrated knives on the bars. The bars are parallel to the doorstep axis. First pulling the tractor handle, it is found to be strange that the harrow does not power regularly. Harrow movement and share the same engine.
