Introduction
Agro Met Field Unit (Coastal Saline Zone, Kakdwip) of Bidhan Chandra Krishi
Viswavidyalaya is situated at the South Eastern part of the state lying between
22"40'38.95" N latitude and 88"18'33.27" E longitude with a mean sea level of 7 m., at
Kakdwip, 35 km away from the Bay of Bengal and beside 117 NH. Nearby railway
station Kakdwip and nearby bus stop is Kakdwip. No airport is available there. The Agro-
Met Field Unit under Integrated Agro-Met Advisory Service (IAAS) newly named as
Gramin Krishi Mausam Sewa (GKMS), implemented on 1st June, 2008 to provide
medium range weather forecast for the farmers based on present climatic condition and
set up operational arrangements for AAS involving extension and information
disseminating agencies.
The coastal saline area in West Bengal is about 1.394 million hectare comprising
whole of South 24-Pargana district (2086 villages in 29 numbers of blocks) and Purba
Medinipur district (3048 villages in 25 numbers of blocks) and few blocks of each of
North 24-Parganas and Howrah districts. Total geographic area of the Agro Climatic
Zone (Coastal Saline Zone): 15326.4 km. Out of the total 9630 km2, 4493 km
2 is
inhibited with people, 4236 km2
is under reserve forests and 657 km2
is under river.
Moreover, nearly 69.08% area of the zone is under the Ganga delta, known as
„Sundarban‟. In South 24-Parganas district 693 number of people are living in km2. There
are 2086 number of villages in 29 blocks where 86.7% of the total population of district
live and on an average 2375 persons per village live in the district.
More than 65% of the cultivable land in coastal area of the country is in the state
of West Bengal alone where the cropping intensity is only 112%. Farmers grow mostly
low-yielding traditional rain fed rice during wet-season leaving most of the lands fallow
during dry-season (January–May) because of soil salinity and the lack of good-quality
irrigation water and also modern agro-technologies due to lack of poor communication
and transportation facility. Crop yields, cropping intensity, production levels and people‟s
quality of livelihood are much lower in this region than in other regions where farmers
are enjoying the fruits of modern agricultural technologies based on high-yielding
varieties, improved fertilizer, water management, improved pest and disease control
measures and weather based agro-advisory. At the same time, with the steady increase in
human population food demand in the area is increasing at similar paces. So, supplying
farmers with alternative production systems with high land and water productivity and
weather based crop cultivation is crucial for food security, enhancing farmers‟ livelihood
and sustaining the environment of the zone.
Present Agricultural situation of this zone
Total geographic area of the Coastal Saline Zone is 15326.4 km. Out of the total
geographical area of 1562340ha, a total of 907166ha (58%) net area is available for crop
cultivation which is also 83% of the four command districts of this Zone.

Livestock information
Livestock forms an integral part of the day to day life and activities of common
farmers of this zone. Apart from supply of milk, eggs and meat required for domestic use.
Besides these, farm yard manure requirements are also fulfilled from animal resources
and also provide some extra income through sale of surplus milk, eggs, meat, hides, skin
and other products. Some farmers possess a pair of bullock or buffalo, a few cows and
heifers. Some farmers also possess a few goats, ducks, cocks or hens. In some S.C.
families it is found few pigs. The major constraints in livestock production and
management are the predominance of genetically unproductive/low productive
indigenous and nondescript animal population of the region. Un feeding and shortage of
green fodder have an adverse effect on the productivity of cattle and buffalo including the
working efficiency of these animals.

Weather condition of South 24 -Parganas from 1st April, 2016 to 31st
March, 2017
The weather scenario of South 24-Parganas is quite variable from the period of 1st
April 2016 to 31st March, 2017. In terms of maximum temperature it has been varied
from 14.00C to 39.0
0C and the minimum 9
0C to 31.0
0C throughout the selected period.
Minimum temperature during winter, 2016 shows very low value particularly in mid
January, 2017. It was varied from 09.00C to 12.
00C (5
th January to 20
th January). As a
result rice seedlings were badly affected by blast disease.
The overall scenario of rainfall pattern showed that good pre monsoon rainfall was
received in the month of May, 2016 (130.6mm). From mid-June good amount of rainfall
was received. Maximum rainfall was received from end of July to mid August
(839.9mm) causing flood situation. In low land area of some blocks of South 24 Parganas
submerged condition was found in the main field of aman paddy. The total amount of
rainfall received in the month of July 492.4mm which is more than the normal.
The humidity range is varied from 50% to 96% throughout the selected period. Less
humidity was recorded during winter month (50%) and maximum value was recorded
during monsoon (96% in June and July).

Verification of the medium range weather forecast Medium range weather forecast of 5 days was received twice a week, i.e., on every
Tuesday and Friday forenoon from Super Computer centre, National centre for Medium
Range Weather Forecasting (NCMRWF), D.S. & T., New Delhi. For the purpose of
verification study, the weather forecasts so obtained during the period under study were
divided into 4 seasons namely-
Winter
Summer
Monsoon
Post monsoon
The verification study was carried out by taking into account both forecast and observed
weather data. The analysis of data was done following the methodologies given by
NCMRWF, New Delhi. Both the qualitative and quantitative verification studies were
conducted by using skill scores and critical values for error structures. Verification study
was done for the following meteorological parameters, which were supplied by the
NCMRWF.
Rainfall
Wind speed
Maximum Temperature
Minimum Temperature
Relative humidity
Verification methods:
Weather forecast of the centre was analyzed for verification following the
meteorologist given by NCMRWF (1999) through their publication entitled Guide for
Agro meteorological Advisory Services.
For rainfall analysis, the quantitative analysis was conducted on YES/NO basis. In
this case, the analysis was done by examining whether the event occurred or not as per
the forecasts received. In case of qualitative analysis of rainfall forecast, ratio score,
Hanssen and Kuipers score (H.K. Sscore) and other was determined using 2X2
contingency table. The quantitative verification analysis was carried out using
critical values for error structure.

Results of verification of medium range weather forecasting
1. Maximum temperature In case of maximum temperature (table-3), the percentage of correct cases was
highest during post-monsoon season followed by pre-monsoon and monsoon
respectively. When correct and usable cases were considered together it has been
observed that the success of forecast of maximum temperature ranges between 96.74 for
post-monsoon and 43.1 for winter.
The “r” value for pre-monsoon, post-monsoon, winter and annual season are not
significant.
2. Minimum temperature
In case of minimum temperature (table-4), the percentage of correct cases was
highest during monsoon season (17.89) followed by post-monsoon, monsoon and winter
seasons respectively. When correct and usable cases were considered together it has been
observed that the success of forecast of minimum temperature ranged between 96.75for
SW-monsoon and 82.75 for winter season.
The “r” value for post-monsoon (0.93) and annual season is significant (0.93)
although the same for other three seasons are not significant.
3. Relative humidity
The results of verification of RH forecasts have been presented in table-5. The
correct forecast varies between 13.82% for monsoon and 5.43% for post-monsoon.

3.1 Scenario of rainfall pattern during monsoon months for last nine years (2008-2016)
Fig: 3.1 Trend of rainfall pattern of last nine years during the monsoon months (June to
September)
The trend of rainfall pattern of last nine years is graphically represented in the
Fig: 3.1. It was found that total amount of rainfall increased from 2008 towards 2016.
From the previous year‟s study it was found that the intensity of rainfall increased from
mid July to August.
17
3.2 Rainfall scenario of South 24-Parganas(2016)
Fig: 3.2 Rainfall scenario of South 24-Parganas in the year 2016
Source: RMC, Kolkata and observatory data of AMFU, Kakdwip
It is seen from this graph (fig.: 3.2) that in the month of June, 2016 the actual rainfall
(227.6 mm) was received slightly lower than the normal rainfall (254.7mm). During July
the amount of rainfall(492.4mm) received showed that a moderate deviation from normal.
Maximum rainfall was received in the month of August (670.5mm). Both in August and
September the amount of rainfall received more than the normal. The harvesting of aman
paddy was badly affected due to stagnation of water till the harvesting period. That time
farmers were advised to harvest the paddy and keep them over the stubble for drying and
avoiding shattering loss.
18
3.3 Rainfall scenario of Purba Medinipur(2016)
Fig: 3.3 Rainfall scenario of Purba Medinipur in the year 2016
Source: RMC, Kolkata
It is seen from this graph (fig.: 3.3) that in the month of June, 2016 the actual rainfall
(216.4mm) was received which is lower than the normal rainfall (256.3mm). During
August maximum amount of rainfall(568.3mm) was received which showed a great
deviation from normal. As a result the newly transplanted kharif paddy field was
submersed in some blocks. During September rainfall was received less than that of
normal rainfall.
19
4.1 Contingency planning for water stagnation due to heavy rainfall
In the year 2016 a good amount of monsoon rainfall was received. Among the monsoon
months the maximum rainfall
was received in the month of
August. Newly transplanted
aman paddy field of some
villages of Lakshmikantapur,
Jaynagar, Kulpi and Canning
block were found in submerged
condition. Farmers were
suggested to keep seedlings in seedbed so that they can re-transplant the seedlings in
place of damaged
seedlings. No bad effect of
heavy rainfall on the aman
paddy field in Diamond
Harbour block was
noticed. In case of poultry
farming we suggested to
maintain the dryness and
thickness of litter by using old
newspaper. It is also advised to
cattle keeper to vaccinate the
cattle against foot and mouth
disease.
21
In Baruipur and Sonarpur block the orchard of Guava and papaya was found with
stagnation of water in
maximum places. Plants
were highly affected by
wilting in the orchards.
Farmers were advised to
drain out the stagnated
water from the orchard as
soon as possible and apply
copper fungicide at the base
of soil around the plants. The ponds were also found flooded somewhere. Farmers were
advised through AAS bulletin to cover the bank by net around the pond to prevent the
exit of fish from pond
and exotic fish from
outside.
22
Correlation study between minimum temperature and blast affected boro paddy seedling
Fig: 5.1 Relation of seedling blast of boro paddy and minimum temperature
In the year 2106 the seedlings of boro paddy was highly affected by blast due to
minimum temperature (below 13.00C). It is shown from the graph that when temperature
falls below 13.00C the young paddy seedling was affected by blast and the intencity of
infestation is reached in maximum when temp was varied from 9.00C-11.0
0C. So it can be
concluded that minimum temperature has a close relation with the incidence of blast of
rice. Farmers were advised to reduce Nitrogenous fertilizer and apply potash fertilizer.
Beside this farmers were advised to make a shade by transparent polythene over the seed
bed to prevent the dew deposition and conserve temperature and also spray fungicide to
prevent the disease intensity.
24
6.1 Krishi Mela
A krishi mela was organized by Bhuban Nagar Rural Development Society,
Kakdwip during the period from
12th to 13
th January, 2016. We
participated in this Krishi Mela and
met the farmers every day to
discuss the adverse effect of
weather on crop cultivation,
fishery, dairy and poultry farming.
Highlights of discussion in the krishi mela
1. Effect of minimum
temperature and
foggy weather in
winter crop
cultivation
2. Registration of
farmers‟ name and
mobile number with
crop code in farmers
portal
3. To aware the farmers about SMS service directed by Farmer Portal by IMD
4. To give suggestion on requirement basis and collect the feedback from farmers.
5. Usefulness of SMS for not only crop cultivation but also for fishery, poultry and
animal husbandry.
26
Feedback from farmers:
In the last year potato production of South 24 Parganas and Purba Medinipur was highly
affected by
minimum
temperature.
Farmers
wanted to
know that
whether in
this year
potato
production
affected or not. Beside this they want to know the symptoms of blast disease and affect of
weather for this disease of boro paddy. They also suggest us to supply good quality of
seeds if possible. Beside crop cultivation they also use the bulletins for poultry and cattle
production Some farmers want suggestion for increasing milk production of goat to
overcome the death of new born baby due to lack of milk. With the help of Animal
husbandry expert we advised them to feed leaves of Subabool to the goats after delivery
of new born baby.
27
Installation of Agro-Meteorological Instrument in AMFU, Kakdwip
In RRS, Kakdwip Conventional Observatory was re-constructed and all the
meteorological instrument viz. maximum
and minimum thermometer, grass
minimum thermometer, rain gauge. Open
Pan evaporimeter, sunshine recorder, soil
thermometer, anemometer and wind vane
were installed by Mr. Sukumar Roy, SA,
RMC, Kolkata. Now the Met. data is being
recorded at 8.30AM and 14.30PM by Agro-
Met field Observer, Mr. Biswajit Kar and the
data updated in IMD website by Technical Officer, Dr. Shibani Chowdhury and every
day Met. data of 8.30am and 14.30pm were send to RMC, Kolkata.
Training programme attended
One Training programme attended by
Technical Officer and Agro-Met field observer
from 15.03.17 to 16.03.17 about
observational procedure and recording of
observational data in monthly
Meteorological Register organized by RMC, Kolkata.
.
28
Farmers Meet & field visit
Field visit and farmers meet was held on 12th
December, 2016 in Diamond Harbour
block. The subject of that meeting was the
usefulness of AAS bulletin for crop
cultivation and overcome the economic loss
due to adverse weather. Around 25 farmers
were present there and participated in
discussion. We also aware them why
they register their name, mobile number
and crop details in farmer portal and
how they receive free SMS in Bengali
through IMD Website. In that meeting
the Technical Officer collected the
email id of some progressive
farmers to disseminate the bulletin
among them and it will be helpful
for framers for farm operation like
spraying, irrigation etc. The
Technical officer also collected
the Whats App number of some
farmers so that they can send
photo of crops and take instant
suggestion from us through
message.
29
AAS bulletin and Farmers’ field visit
We prepare AAS bulletin bi-lingual and biweekly (Tuesday and Friday) on the basis
of forecast data received from RMC, Kolkata and disseminate
to the progressive farmers, three disseminating agencies, two
NGO, P.A.O. of South 24 Parganas, two KVK, KCC, ATMA
and 29 numbers of B.D.O of the district South 24 Parganas
and 25 numbers of B.D.O. of the district Purba Medinipur.
When the bulletin is prepared we incorporate the NDVI and
SPI values delivered by IMD and
also send SMS through Kisan
SMS Portal around 12099 numbers of farmers of South 24
Parganas and Purba Medinipur. In AIR the bulletin is
broadcast at 6:30 A.M. in Gitanjali and send to Doordarshan
by mail [email protected]. The total number of
bulletin disseminated by AMFU, Kakdwip in the year 2016
was 98 and the total numbers of SMS delivered through
Farmers‟ Portal are 98. Several numbers of field visits were
conducted for direct contact with farmers to solve their
problem. We always touch the farmers regarding their problems through the field visit. In
this year a large number of farmers name, mobile number and crop details were registered
in the IMD website for getting SMS at free of cost according to the season and crop. We
expect that it will be very helpful to the farmers.
31
Economic impact of AAS bulletin to the farmers
In the year 2016 it was observed that minimum temperature range was
comparatively low which resulted less pest & disease infestation was observed in potato
field. At that time farmers were advised through AAS bulletin not to use pesticides for
decreasing input cost and
increasing monetary
return. The production of
potato was one quintal
per katha and the market
price was Rs. 700/- per
quintal. Farmers who
followed the advice given
through AAS bulletin, were benefited around Rs.500/- per katha (Cost of cultivation=Rs.
200/- per katha). But in the current year (2017) there was a chance of late blight disease of
potato and advisory was given through AAS bulletin from AMFU, Kakdwip to protect
their crop by spraying fungicide as preventive measure. Maximum farmers minimize
their loss from late blight attack by using fungicide as preventive measure with the help
of weather forecasting. The farmers
who cultivate cole crop like
cauliflower, cabbage etc. were
advised them not to use excessive
nitrogenous fertilizer. They got
good yield and were benefitted
more as their cost of cultivation
