Major Cropping sequence
- Old – Alluvial Zone
•Winter rice - Fallow
•Winter rice - Summer rice
•Maize - winter rice - Potato / wheat / vegetable
(emerging)
- Terai Zone
•Winter rice - Fallow
•Jute / Maize – winter rice – Potato / vegetable
Intervening Areas for Wheat Area expansion
- Old – Alluvial Zone
•Replacement of summer rice by wheat
•Expansion of wheat area through
covering fallow and utilizing excess water
from boro-paddy for supplementary use
-Terai Zone
 Expansion of area through covering
fallow utilizing residual soil moisture
 Application of supplementary irrigation at
critical growth stage through decreasing
potato area.
Major constraints of wheat production in West Bengal
•Late transplanting of paddy after jute coupled with long duration varieties
like Swarna
•Late sowing of wheat
- Loss / problem in harvesting due to occurrence of pre-monsoon
rain
- Suffering from terminal heat during panical / ripening stage
- Non-availability of good late sown variety
- Micronutrient deficiency such as boron cause spikelet sterility in
wheat
- Occurrence of foliar blight diseases like Zonate Eye Spot, Leaf
Blight, Tan Spot, Spot Blotch
Spikelet sterility
Preharvest sprouting
Foliar blight

Selection of stress tolerant wheat
• Selection of terminal heat tolerant
varieties for late (15th December) and very late
(30th December) sown conditions
•
•
Late Sown- Francolin (4.05 t/ha), and NW 2036
(3.40 t/ha)
Very Late Sown- Francolin (3.24 t/ha), and NW
2036 (2.84 t/ha)

ZERO-TILLAGE WHEAT
(Conservation Agriculture Approach)
•
•
•
•
•
Use varieties suitable for late sowing
To utilize residual soil moisture
Area expansion of wheat for high ecological land use.
To combat weed problem
Minimize disease occurrence

Weed- A major problem for NEPZ
Polygonum pensylvanicum
Polygonum persicaria
Weed pressure in wheat at Coochbehar
Polygonum hydropiper
Zero tillage had considerably reduced weed pressure,
however, it caused shifting of weed flora from
•Polygonum and
•Stellaria media
to
•Hydrocotyl ranunculoides, Solanum niagrum,
• New species of Polygonum (?)
•Ageratum conyzoides
•Stellaria acquatica

Development of system approach adopting conservation
measure :
- Zero tillage sowing for all the crops
- Introduction of medium duration paddy varieties ( 130 days)
- Direct seeded rice based on weather forecasting
- Unpuddled transplanted rice – through manually /
transportation
- Inclusion of legume in crop rotation / mix cropping during
prekharif / rabi
season
- Bio-priming of seeds / application of bio-fertilizers
- Crop residue management

micronutrients (Zn and B)
ii) Low soil organic matter
iii) Acidic pH
iv) Sandy to sandy loam texture
v) Fragmented land
