Abstract
India ranks as second largest country for agro-based economy having
about 1.79 MKM
2
agricultural land that generates approximately 686
Million Tonnes (MT) of gross crop residues including approximately
234 MT surplus residues annually. In 686 MT crop residue,
contribution of crop types as well as states is variable. In the present
study, the role of crop residue as an important natural and renewable
resource along with their on and off farm management options
having their own benefts, drawbacks and limitations were discussed.
Various terminologies used for crops’ residue and methodoloies
used to estimate their generation potential were analysed. Different
factors regulating the crop residue usage for diverse purposes
which affects their end use were identifed and listed. As, raw and
condensed form of crop residues have different physico-chemical
properties and resource value. Various on and off farm crop residue
management options including crop residue burning, residue
removal, residue retention, residue incorporation, composting,
biochar production, livestock feed, mushroom cultivation, biofuel
biogas and bioenergy production from different crop residues were
compared. Various Government initiatives to minimise and support
the unsustainable and sustainable crop residue management options,
respectively were reviewed.
Key words: Crop residues, Crop residue generation potential, Crop
Residue management option, On and Off farm options.
1. Introduction
In India total agricultural land occupies 1.79 MKM
2
(60.5%
of total land area). As per World Bank (2010), agricultural
land basically corresponds to the portion of total land
which is arable (53.2%). 3.8% and 3.5% arable land is
under permanent crops and pasture, respectively. With net
area of around 180 Million hectare under the agricultural
cultivation and about 140% cropping intensity (Cardoen
et al., 2015), India generates huge amount of agricultural
residues. Agricultural residues include - livestock residue
(both commercial and household livestock) and crop
residue (includes non-edible plant parts that are left in the
feld after the crop being harvested, thrashed or left after
pastures grazed including leaves, stalk, stubbles, straws and
roots) (FAO, 2014; Lal, 2005).Crop residues are basically
the crop parts that remained after all the economic part
of the crop has been separated out (Shahane et. al., 2016).
As per the estimations, India generates around 686 Million
Tonnes (MT) (Hiloidhari et al., 2014; Singh et al., 2020)
of crop residue on farm plus off farm annually. Of total
residue generated, feld crops such as cereals, pulses,
sugarcane and oilseeds contribute 545 MT, 79.8 MT is
contributed by fber crops such as Jute and cotton and 61
