Rain gun irrigation

Farm Questions

Dear Mr. Chandra,
I too presume that levelling is not required for rain gun irrigation. Will any one of the members confirm this presumption please.
C. Siva Sankara Reddy

Why would one need leveling. Rain gun is nothing but a large sprinkler. I have seen it in action at Krishi Mela. One attached to a tractor.

It just works like fire fighting hose. Enormous amounts of water under high pressure is sprayed into the sky having rain like effect. And some mechanisms to disrupt the flow at the nozzle, so it gets scattered.

    3)Advantages over drip for the same.

Hi?
Providing water through Rain gun spread water every part of the orchard to ensure coolness in the orchard along with micro climate to grow different variety spices for biodiversity. This is ultimate advantages to have any multicolor if required.
One can easily control the force of water delivery as per their requirement of the crops including space mentioned by you.
All the best.

Land leveling is not required for rain gun irrigation. One has to ensure the pressure level of pumped water to be 2 inch per square metre, minimum. This is accomplished by 5HP pump. Best suitable for sugarcane, groundnut, carrot type of cultivation.

Dear Mr. Vasudevan thanks for the response. A small clarification. Can a 5HP pump work for a 250 feet depth bore well with rain gun.
C. Siva Sankara Reddy

Reddygaru
one small correction, you please read 2 inch as 2 kg in my previous relpy. 5HP pump delivering water from 250 feet can not meet the stipulated pressure requirement and hence you may have to go for 7HP. In my farm, we have open well (80 feet), 5HP pump is just sufficient.

Dear Mr. Vasudevan Just a small clarification. Like the application of fertilisers and chemicals can we take up application of gobar gas slurry with the help of rain gun. If so with what efficiency.

31

Yes, it is possible. But, the slurry may deposit /spread on the green leaves of the plants, which may not be OK for the photosynthesis point of view. This is my view. If the slurry is in diluted form we can go ahead.

Dear Vasudevan,

Thanks for your posting.
This the first time I heard about the Rain Gun. Please let me know the possibility of using rain gun for cultivation of Co3 grass.
I collect the urine and waste water in to a tank and using a slurry pump to irrigate to the grass field. Is it advisable to use rain gun on this system?

Please provide the positives and negatives and also confirm the availability of this system in Kerala and their address.

Thank you.

The slurry is diluted with almost 90% of water. If possible please attach some photos of your rain gun irrigation system. So that I can grasp some idea instead of imagination.
Also provide address and contact number of the supplier in Kerala or in other state.

  1. Rain gun angle must be steep. Make it like artificial Natural rain. Otherwise grass(only taller grass) will bend because of water force.
  2. Grass must be washed before feeding to cattle otherwise they may not be interested because of urine and dung smell on it.
  3. If you are pumping from a biodigester (Jeevasara Unit) provide a seeve otherwise nozzle gets clogged with fibre particles frequently.

Thanks,

Hi Vasudevan,

Do you know if raingun works when the bore pumps intermittently? Did you get into that situation ever?

Chandra

Hi guys…
Can we use rain gun for banana plantation and vegetables lik brinjal etc

Dear Mr Chandra
As I was out of station I did not answer you question. I have two open wells with submersible pumps. No problem with that. If the bore pump is capable of discharging at least 2kg per square cm, the rain gun can work.
