New Initiatives

1) Solar Powered Treadle Pump

80W photovoltaic solar panel Expected discharge of water is 10,000 litres per day Suction lift of 7 meters.

Specifications:

• 3.5 inch diameter single cylinder reciprocating type positive displacement pump 
•  Maximum lift: 7 m suction with open delivery
• Discharge: Varies from 700lph to 1500lph depending upon solar intensity.
•  24V 120W DC motor with 18V 80W photovoltaic solar module.
•  Status: Under in- house development phase. First prototype prepared and under test.
•  Estimated Cost: US $ 200












2) Micro Sprinkler

 Micro Sprinkler: A low cost single path spinner type micro sprinkler specially designed to operate at low pressures.

Applications:

Irrigation in close growing vegetables like potato, onion, raddish, carrot, leafy vegetables etc.

Specifications:

Nozzle- single nozzle 2.5 mm diameter
Operating pressure- 5 to 10 m or 0.5 to 1.0 kg/cm2
Pipe system- low cost layflat pipes
Lateral and sprinkler spacing – 6 X 6, 5 x 5 and 4X4 (triangular spacing) m at 10, 8 and 5 m nozzle pressure head respectively
Wetted diameter- 11 m
Coefficient of uniformity- 80 %
Operating system- manually operated pressure treadle pump, diesel engines, electric motors.
Gross application rate-  4.7, 6 and 7.5 mm/hr at 10, 8 and 5 m heads respectively.
 















3) Low Cost Green House
Is being made using low cost bamboo structure and plastic rope. The structure is  oriented from east to west to harness the maximum green house effect. The maximum exposed area is towards south to harness maximum green house effect. The north side is covered with mainly high value creepers. The structure allows for tremendous natural ventilation. The technology is under in-house testing and evaluation.











4) Low Cost Cold Storage
The Low Cost On-Farm Storage is being designed to preserve vegetables for about 5 days. It works on Evaporative Cooling Process and therefore the effectiveness depends upon the climatic factors (Relative humidity). It is therefore best suited in dry areas in summers. This is also under in-house testing and evaluation.
