hi to everyone and GG
this is direced to GG but everyone is welcome to give me some gyaan.
i am doing a trial run of growing 3950 tomato plants in 2000 sq.mtrs,in grow bags.grow bags size is 10 inches height and 12 inches wide .each bag contains 4.5 kgs of red soil and 640 gms of basal application like enriched FYM,neemcake,N,P,K,DAP,SSP,CAN,MOP,etc etc.
as a matter of fact i've got zero experience. ive never watered the plants at my home :p
so, as i have given you an idea of what im upto. i have a series of questions.
1. how many ltrs of water does a tomato plant need per day during nov-march?or during different stages of growth?
2.can boyu pumps be used for irrigation & fertigation?
3. as my plot area area is 2000sq mtrs, the length of the drip laterals would be 46 meters long.can boyu pumps produce such kind of pressure?
im thinking hard but cant come across anymore questions to ask.that's all for now.after i get a reply,definitely some doubts will pop up in my mind and ill get back again.

sorry about the delay.
A tomato plant can consume 1-3 litres of water per day. more so if the plants are in hot weather and full of fruits.
Boyu pumps have lot of models. If youa re asking about the submersible ones that used in aquariums. NO they wont supply the pressure required.
You have to calculate how many drippers and what discharge rate your drippers are giving. lets say you have 1000 drippers of 2LPH (liters per hour) then you need to have a flow rate of 2000 liters per hour. Use this as a guide to select the power of the pump.
Why would you want to have 3950 plants when you have no experience in agriculture / gardening? Growing in 1/2 acre is no small feat that too in grow bags. Any particular reason that made you put in NPK and SSP, MOP and CAN? I know you are only looking for advice on watering but I am really surprised with your choice of combination of fertilizers and volume of the trail run.
As far as watering is concerned, you will need 1-3 liters / day as GG indicated. In your case you need at least 8000 liters discharge / day. Assuming 4 hours of power supply you would need 2000 liter capacity pump. Add 30% to 50% towards head loss due to piping etc. As you are based in Hyderabad, my suggestion is you go to Netafim's office in Balanagar (Near Vimal Theater) and ask them for advice. As you have not mentioned the layout of your farm I do not know if cheaper alternatives such as gravity feed drip will work.
and hi srikanth. i am doing this as per IIHR bangalore precision farming method. this is just a trial. ill be doing the same project in 4 acres(31600 plants) in april 2015.
ive already met netafim guys way long back. the layout for 2000 sq mtrs is 46mtrs*46mtrs.
a good discussion is always heplfull.
Please give me the link to the precision farming method from IIHR. If you are interested we can do a collaboration. I have a spare horticultural greenhouse of about 600 sq mts. It already has trellising for tomatoes. The greenhouse is in Khammam. Please call me if you are interested to discuss further at nine-eight-six-six-three-zero-zero-seven-four-five.
there's no web link on the net. i went to IIHR last month to get the info and seeds.you can get seeds through courier also.
you have a spare greenhouse??thats great man. i would like to collaborate but i stay in sainikpuri and my farm is only 18kms from my place.its near hakimpet air force station. khammam is way too far. thanks for the offer though.
i will definitely call you.
Please do call me when you get a chance. I would like to discuss further.
I am also a newbie to gardening from Madinaguda,Hyderabad.
Planning to start balcony/terrace gardening at my flat. Let me know if i can meet you personally as we are staying nearby.
