Presentation on
Emperor Grass
by
Prof. Dr. G. Kumaravelu
(Dec 2012)
5 MONTHS OLD Napier Bajra hybrid Co4
Emperor Grass
(Cumbu Napier Hybrid)
=
Napier – Elephant grass of Africa
x
Kambu (Bajra) India
Triploid Sterile Hybrid – F1
F2 – (Non viable)
Therefore, propagation only through sibs (cuttings)
From 1954, every year,
repeatedly the crossing is made
and progeny evaluated.
NBCO4 – Evolved by TNAU
during 2008
5 MONTHS OLD CROP
HARVESTING OF 5 MONTHS OLD CROP
HARVESTING OF 5 MONTHS OLD CROP
28 / 09 / 2011 Weighment of 5 months old crop tested by the author Dr. GK (28 / 09 / 2011)
Highest Yield
400 to 800 MT / ha / year (green) Data recorded by Dr. GK. on 28 / 09 / 2011
5 months old crop
640 MT / ha (green)
Sample No. No. of Culms Stem Wt in Kg Leaf Wt in Kg Total Biomass
in Kg
1 19 14.20 3.50 17.50
2 19 14.00 3.00 17.00
3 17 12.50 3.00 15.00
Average 18 13.50 3.15 16.65
TOTAL BIOMASS PER HA – 640 GREEN MT
(5 to 6 months first ratoon crop)
5 MONTHS OLD SECOND RATOON CROP
2nd Ratoon crop weight
After 5 months (22 / 02 / 2012)
1160 MT / ha (green)
TOTAL BIOMASS
First Ratoon Crop – 640 green MT / ha (80% moisture)
Second Ratoon Crop – 770 green MT / ha (80% moisture)
(This data is collected from minimum size sample plots of less than 20 cents
only. Therefore this should be taken only as an indicator of high yielding
nature of this hybrid grass. It is suggested that a field sample trial maybe
carried out by the users for one harvest upto 5 to 6 months to evaluate its
yield potential for that particular soil and management status.
Average Sugarcane yield in Tamilnadu – 40 Ton / acre
27% is the weight of the bagasse (50% moisture)
The yield of bagasse is about 11 tons per acre
Highest yield in sugarcane is 100 Tons / acre
Even in this the yield of bagasse will be 27 Tons / acre
On an average, safely, we may presume its potential as following
Emperor Grass can yield a minimum of 160 Green Tons / acre / year
@ 50% moisture it yields 80 Tons / acre / year
Emperor Grass can yield a maximum of 250 Green Tons / acre / year
@ 50% moisture it yields 125 Tons / acre / year
Applications of Emperor Grass
• Electric power production
• Briquettes for substitution of coal, lignite in Thermal Power Plants
and Industrial, Commercial heating systems
• Biogas production
• Cellulosic Ethanol / Butanol
• Probably paper pulp
• Bio chemicals and Bio plastics
• Bio oil / Biodiesel
Gross Calorific Value
4038 Kcal / kg
Direct Combustion
in Biomass Power Plant
• Similar to bagasse used in Sugar
Mills to produce electricity under co-
generation mode, the biomass from
this grass can also be used.
• We have tested it to have similar
calorific value like bagasse.

BRIQUETTING OF EMPEROR GRASS IN PROGRESS
EMPEROR GRASS BRIQUETTES – GROSS CALORIFIC VALUE 4284 Kcal
Gross Calorific Value
Briquettes
4284 Kcal / kg
MAINLY USED AS FODDER FOR MILCHING COWS
Cows like it because of its sweetness. Note the houseflies on the fresh cut
stems indicating more sweetness (sugars).
