• Four soil orders viz.
Entisols,
Inceptisols,
Alfisols and Ultisols have
been identified in Tripura.
• Soils of Tripura have been
grouped into five soil
reaction
classes
viz.
extremely acidic (<4.5 pH)10%, very strongly acidic
(4.6-5.0)-26%,
strongly
acidic (5.1-5.5)- 54% and
medium (5.6-6.0)-8% and

OUR AIM
We are working together through various
disciplines to fulfill the following three
aspects:
Food Security : 5.13 lakh MT (1999)
6.48 lakh MT (2010)
8.62 lakh MT ( 2012-target)
Livelihood Improvement: 1.16 lakh mostly
tribal beneficiaries, have been provided with
1.72 lakh hectares under Forest Right
Act,2006.
 Sustainable Environment
contd..
Sustainable Environment
• Efficient use of Rain Water :
(i) Integrated Water Shed Management
Programme in 238 ha.
(ii) NWDPRA, IWDP, WDPSCA- 736.35 ha.
through 6898 Water Harvesting Structures.
• Use of Bio fertilizer :1.4 tons to 758 tons
• Improving the conjunctive use of
fertilizer.
Addressing unexplored areas
• Tilla
land
utilization
through mixed cropping –
increase in net cropped
area.
Tilla land utilization with
diversified cropping
• 1.72 lakh ha land made
available to 1.16 lakh
tribals for cultivation
under Forest Dwellers’
Rights Act.
• Survey on present status,
crop suitability, mixed
cropping etc of the
allotted land
is in
progress.
Colocasia in tilla land-source of
starch to the tribal people
Tilla Land Utilization
•No tillage/minimal
tillage.
•Major crops in the
system are :
Paddy, Maize, Bottle Gourd,
Radish,Cauliflower,
Sesamum,
Rapeseed, Blackgram, Arhar,
Pineapple, Banana, Ginger, Chilli
Bamboo, etc.
Maize in Jhum
Paddy in tilla land with
minimal land development
Black gram-Bottle gourd
after paddy harvest
Comparison between Traditional and Improved System
Traditional System Modern system/ Improved system.
Slash and burn every
fourth year.
No slash and burn.
Crop harvest over two seasons in each year.
Integrated crop & soil management.
Enhancing income generation with continued
community approach in crop management.
No harvest except
Pineapple & banana in
second & third year and
Bamboo in the fourth
year.
Discontinuation of shifting Agriculture and
inducing a feeling of ownership due to assured
return which facilitated micro level planning
and development.
Deterioration in soil
fertility and
environmental
pollution.
To reckon with a socio Economic change duly
addressing to environmental concerns.
Management Approach in Terraced Land
• Systematic cultivation
permits better agricultural
operations.
• Facilitates seed treatment
,Bio fertilizer applications
etc.
• Supports use of fertilizers
soil ameliorants incubated
in organic manure.
• Use of liquid fertilizers .
• Continued use of
Indigenous Technical
Knowledge.
INTRODUCTION OF NEW VARIETIES
• Five new varieties introduced in the
Improved system of tilla land cultivation (
Bali White, Bali Red, Yapuna Yamukh,
Kimin and Nsusu).
• Introduction of short duration varieties of
paddy in plain land situation for 13000
hectares which facilitates to increase
cropping intensity up to 300% (PaddyPaddy- Vegetable) in a year.
Support needed for implementation
• The subsidy for soil ameliorants should be increased from
Rs.500/- to Rs. 1500/- per ha. Lime costing Rs.3/- per kg in
orissa costs Rs.10/- in Tripura.
• 30% of land out of 1,72,00 ha. distributed under Forest Act
needs to be covered with Agri /Horticultural crops. Support
under dry land Agriculture is needed through NFSM- pulses,
Isopom maize.
• Micro-irrigation needs support further
• Present productivity is 2.6 T/ha. may be increased to
3.5T/ha. by increasing N:P:K application from 39 kg/ha. to
100 kg/ha.
• In the 2nd Green Revolution Plan, Tripura which is not
covered in NFSM rice, NFSM pulses, Isopom maize etc.
should be included
