for biomass quick biological decomposition, in which the farm equipment come into play a
major role. The ICAR-CRIDA developed crop stalk shredder machine, which shreds both
wine type cover crop such as velvet bean and tall legumes like dhaincha, sun hemp as well.
The machine was tested intensively on several crops for in-situ biomass shredding and as
well as on green manure crops. The machine was able to shred biomass completely of
dhaincha and sun hemp, leaving a 10 – 15 cm height stubbles over the soil surface. The
machine was also found effective on some field crop stalks like castor, maize and cotton as
well, which are grown as inter crop in the early years of horticulture crops. The nature of
blades provided in the machine severed the stems of cut biomass such a way, which avoided
tillering of stubbles completely.
Conclusion
The developed machines from this study show that, the machine design parameters play a
significant role on weed or cover crop biomass cutting efficiency. It is concluded that, the
selection of machine depends on intended purpose such as soil to be manipulated or biomass
or cover crop to be managed for weed suppression.

The global average temperature has risen by around 1°C since pre-industrial times. Even if all
the commitments (called the “Nationally Determined Contributions”) made met, it is projected
that global warming will exceed 3°C by the end of the century. The average temperature in
India is projected to rise by approximately 4.4°Cover the recent past (1976–2005 average). An
increase in temperature and elevated CO 2 (eCO 2) influence crop growth significantly and in
turn affect the insect herbivores both directly and indirectly. Though it is known that the
