Presently 
farmers in Tamil Nadu are battling two problems — acute water shortage 
and a major power crisis. “Even to pump out the fast dwindling water 
from the wells for irrigating the crops farmers need electricity. 
Sometimes they get it after 14 hours or some days they get the supply in
 6-7 hours.
“There is no 
fixed time. A few months ago, when I was visiting a field in Kadayam 
region in Tirunelveli I saw a farmer spraying his 25 cents of rose crop 
carrying a hand operated sprayer. He was walking several times towards 
his field bund to fill his manual sprayer.
Rapidly dwindling
“Only a few 
more weeks were left for him to do the daily pickings after which he 
cannot continue, since summer is fast approaching and already the water 
level in the wells is rapidly dwindling,” says Dr. P.David Raja Beula, 
Assistant Director of Horticulture Kadayam.
Mr. David has 
developed a device called ‘Drought fighter’ that promises to be of help 
during dry season or when water availability is low.
The main 
feature of this device is that it does not require electricity to 
operate it, but works on solar energy. It is priced at Rs.15,000.
“The machine is
 mainly developed to help a farmer conserve water and use the available 
water efficiently for irrigating his crops, without using electricity. 
Already several wells in the region are fast becoming dry with no water.
 Throughout the State it is the same. Having already developed a solar 
spray I decided to apply the same idea and developed this new water 
conserving machine that runs on solar power,” he says.
The drought fighter has a two-metre-long sucking tube and a 20 metre long delivery hose with a lance and a nozzle attached.
An 18 watt 
small solar panel is attached to a 12 volt electric motor. All farmers 
need to do is place the solar panel along with the motor under the sun 
for an hour and start using it.
Running time
Once charged it
 can continuously run for three hours, after which the motor needs to be
 switched off and the panel needs to be charged again.
Whenever there 
is electricity, water from the well can be pumped into four or five 200 
litres plastic barrels. Later the drought fighter is kept on top of one 
of the barrels and the sucking hose immersed in it..
Water can be 
sprayed in a 360 degrees circle using the 20 metre-long delivery hose, 
covering 25 percents of area at a time. More area can be covered by 
periodically shifting of the entire system.
Farmers can also mix their choice of pesticides or bio-pesticides in the barrel and spray.
As water need 
not be carried on the back it reduces physical labour for the farmer. 
The device can be used to cultivate almost all crops.
Major advantage
“The major 
advantage of this over the traditional back pack sprayer is that a 
farmer need not have to carry the weight of 16 litres of water on his 
back every time. All he needs to do is place the plastic barrels in 
different places in the field, fill them with water and use this machine
 to irrigate, spray his crops,” explains Mr. David.
Mr. Mathew, a 
farmer from Thiruvananthapuram, who uses this drought fighter to spray 
his betel vine and pepper crop says, “It is quite a sturdy instrument 
and requires only one person to operate it. Since it is powered by solar
 energy I save on the cost of fuel.”
Lot of queries
“Even when the 
well has minimum quantity of water, vegetables and flowers can be 
cultivated in a few cents of land using this device. In Kadayam block, 
Tirunelveli farmers were encouraged to carry on flower cultivation with 
the help of this drought fighter and now our Horticulture office is 
flooded with requests from farmers to purchase hybrid Tomato, Bhendi, 
Brinjal, Bitter gourd and leafy vegetables seeds,” says Mr. David.
“Till date I 
have manufactured this device only on order. And nationalized banks are 
giving credit assistance to farmers to buy this machine,” he says.
