CROP PRODUCTION AND MANAGEMENT

Last summer, Shashank visited his aunt in Jaisalmer. He was surprised to see the small kitchen garden his aunt had maintained. “Maasi, I was told Jaisalmer has very scanty rainfall. Yet, you have such a beautiful garden” exclaimed Shashank.

“You are right”, said massi looking at the garden. “A lot of people here use very little water and conserve moisture by dry farming techniques. Infact I use a much simpler yet very effective method” added Maasi taking Shashank to the garden. Do you want to try maasi's method of irrigation in your garden too?

You will need: 

1. Two saplings of the same plant.

2. Earthen pot / surahi.

3. Nail / Any other pointed hard object to make holes.

4. Water

5. Khurpi

6. Measuring tape

7. Mixture of sand and loamy soil.

What to do:

Plant two saplings A and B at least a meter apart from each other in your garden.

Take an earthen pot / surahi and make small holes on its base and on one side of it with a sharp nail.

Bury  the  pot  in  such  a  way  that  its mouth remains above the pit and it is at a distance of about 30 cm from the base of sapling B.

Fill the pot with water and cover its mouth with a lid. 

Let the sapling A be watered directly once  a  week  while  sapling  B  be watered  only  by  filling  the  pot  with water once a week.

Do  you  notice  any  difference  in  the rate of growth of the two saplings? If so why?
