1. Answer the following questions In three to four sentences each:

Question 1.
Why is different volume of water emitted according to the type of land?
Answer:
Drip irrigation is suitable for most soils. But the volume of water emitted differs according to the type of land. On clay soils water must be applied slowly to avoid water ponding and run off. On the other hand, on sandy soils higher emitter discharge rates will be needed to ensure adequate lateral wetting of the soil.

Question 2.
What is the role of control head In drip irrigation plant?
Answer:
The pump unit takes water from the source and provides the right pressure for delivery into the pipe system. The control head consists of valves to control the discharge and pressure. In the entire system. Some control head units contain a filter and fertilizer or nutrient tank. These slowly add a measured dose of fertilizer Into the water during irrigation.

Question 3.
It the water for Irrigation is full of sediments, … (Complete the sentence.)
Answer:
If the water for Irrigation Is full of sediments, filtration of such water is badly needed.

Question 4.

Answer:

Irrigation Advantages Limitations
1. Conventional Irrigation 1.  Does not require any technical knowledge.
2.   Has lesser economic investment.
3.   Irrigates more area.
4.   Crops get sufficient water.
1. Due to seepage in drains, wastage of water is caused.

2. Creation of problem of waterlogging.

3. Not suitable in all types of crops and for all soil compositions.

4. Due to filling of excess water, there is risk of underground salts coming up to the surface level.

5. Not possible to get balanced supply of water.

Drip Irrigation 1. Water directly reaches the roots of the plants, which takes water to plants in balanced quantities.

2. Saves 30 to 70 percent water and it is possible to irrigate three times more area with the same amount of water.

3.  Weeds do not spread because water reaches only near plants and does not spread in the whole field.

4.   Fertilizers and insecticides can also be supplied along with water.

5.   Crop production is higher by 20 to 40 percent because plants can get air and water in required quantities.

6. Lesser labourers are required for irrigation work.

7.  Bacteria causing diseases in crops do not grow because of dry atmosphere near plants.

1. This method is very expensive.

2. Requires special technical knowledge for successful operation of this method.

3. In heavy soils, it creates problems of flow and water blockages.

4. It is not suitable for every crop.

GSEB Solutions Class 11 English Unit 9 Read 3 Drip Irrigation

Question 7.
Which one would you select for your garden / farm – drip irrigation or conventional watering ? Why?
Answer:
I would surely select drip irrigation for irrigating my garden / farm because even if it is expensive, I would definitely care for saving water. I do not need to employ labourers for the irrigation work. I would save myself from the labour of weeding too.

I can supply fertilizers and insecticides along with the water-supply in pipelines. I would also like to have better results – fruits, flowers and vegetables – adopting this method.

I can also be able to keep the plants in my garden away from bacteria. Since drip irrigation is more beneficial in every respect than that of conventional irrigation, I would definitely like to go for it.

Short Notes

Write a short note focussing on the questions:

Drip Irrigation
(1) What is drip irrigation ?
(2) How is water applied to the plant ?
(3) How does it work ?
(4) What are the benefits of it ?
(5) What is the main problem of this type of irrigation ?
(6) Why is drip irrigation better than other types of irrigation ?
Answer:
Drip irrigation is a system in which dripping water is applied close to plants at very low rates (2-20 litres/hour). In this system small diameter plastic pipes are fitted with outlets called emitters. In this system, only that part of soil in which the roots grow is wetted, unlike surface and sprinkler irrigation. Drip irrigation is most suitable for row crops (vegetables, soft fruit, etc.) and tree and vine orchards where one or more emitters can be provided for each plant.

GSEB Solutions Class 11 English Unit 9 Read 3 Drip Irrigation

Drip irrigation is suitable for most soils, may it be clay soil or sandy soil. One of the main problems with drip irrigation is blockage of the emitters, in such cases, filtration of the irrigation water is needed. The pump unit takes water from the source and provides the right pressure for delivery into the pipe system. The control head consists of valves to control the discharge and pressure in the entire system.

Some control head units contain a filter and fertilizer or nutrient tank. These slowly add a measured dose of fertilizer into water during irrigation. Mainlines, submains and laterals supply water from the control head into the fields. In this system wastage of water is avoided, plants get enough water to grow and no extra arrangement is done to supply fertilizers.

Activity

Question 1.
Imagine that you are travelling by a public vehicle. There are a few passengers in it. It’s the rainy season. There are showers of rain. It’s about 11 pm. Suddenly, your vehicle stops. After repeated attempts of the driver, it does not start. What will be your feelings ? What will you do? How will you reach your destination ? How will you help your fellow passengers and driver? Write about your feelings and experience.
Answer:
If the public vehicle, in which I am travelling with other passengers, gets out of order at 11 o’clock at night in the rainy season, it naturally becomes a difficult task to get help at the odd hour.

Still I will do my best, not only for my sake but also for the sake of my fellow passengers. Very soon I will contact the public transport agency on my cellphone. I will request them to send stand-by vehicle to make us reach our destination.

If the driver expresses his helplessness, I would take him out of tension. May be other passengers would start abusing him, I will try to pacify them that it is not the fault of the driver. If the transport agency gives us assurance that they will make some arrangement soon, we are supposed to wait till it comes. In such a situation, I would try to divert the attention of the passengers.

I would ask them to get down from the bus and enjoy the light of the moon. I will request ; them to sit in a circle and I will start singing some old film-songs. They would join me soon. Then I will request them to come along and show their talent or speciality one by one.

Write an email to your friend about this technique without sending this picture. Tell him / her what to do and how will it help the plant.
Answer:
To : harekrishna@vansali.com
Subject: watering the plants in our absence
Dear Krishna,
We are going out of station for 10 days and are worried that without water, the plants in my backyard will wither. I have taken help of technology. I have set all the plants pots in a row and run a PVC pipe all along almost 8 pots. I have tied the pipe with each of the pots and set an emitter for each pot. Then I have attached this lateral pipe with the main waterline. But I have set a timer in between as it functions in a washing machine. The timer would allow the water to flow from the main to the lateral pipe only for half an hour every morning. The emitters are hardly 0.2 mm, so naturally the flow of water would not be more than the required amount. Howz it
Affectionately yours,
Manthan Joshi.

Drip Irrigation Summary in Gujarati

ટપક સિંચાઈ પદ્ધતિમાં નાના વેહવાળી પ્લાસ્ટિકની પાઇપમાં નાનાં નાનાં કાણાં પાડેલાં હોય છે. આ કાણાંમાંથી ધીમે ધીમે ટપકતું પાણી છેક છોડના મૂળ સુધી પહોંચે છે અને છોડને જરૂરી એવા ભેજનું યોગ્ય પ્રમાણ માટીમાં જળવાઈ રહે છે. શાકભાજી, ફળો, વેલીઓ (દ્રાક્ષ વગેરે) માટે આ પદ્ધતિ વધારે ઉપયોગી છે.

જોકે આ પદ્ધતિની ગોઠવણીમાં ખર્ચ ઘણો વધારે થાય છે. આ પદ્ધતિમાં પાળાઓને સમાંતર પાઇપ્સ ગોઠવવામાં આવે છે અને કોઈ પણ પ્રકારની જમીન માટે આ પદ્ધતિ અનુકૂળ છે. આ પદ્ધતિની મર્યાદા એ છે કે પાઇપમાંથી પાણી નીકળવાનાં કાણાં પાણીમાં આવતા કચરાને લીધે વારંવાર ભરાઈ જાય છે. તેથી સિંચાઈનું પાણી કચરો ગળાઈને પછી પાઇપમાં જાય તે જરૂરી છે.

આ પદ્ધતિમાં એક પંપ યુનિટ ગોઠવવામાં આવે છે. જે સ્રોતમાંથી પાણી ઉઠાવી ખૂબ જ દબાણપૂર્વક ખેતરમાં દૂર સુધી પહોંચાડે છે. કેટલાક પંપ યુનિટ સાથે ફિલ્ટર, ખાતર કે છોડ સુધી પહોંચાડવા અન્ય પોષક તત્ત્વોની ટાંકીઓ જોડેલી હોય છે.

તેથી પાણી સાથે ખાતર, જંતુનાશક દવા તથા છોડના વિકાસ માટે જરૂરી અન્ય પોષક દ્રવ્યો પણ છોડના મૂળ સુધી પહોંચાડી શકાય. મુખ્ય લાઇન, પેટાલાઇન અને છેક છોડના મૂળ સુધી પહોંચતી પાઇપલાઇન પી.વી.સી. કે પૉલિઇથીલિનની બનેલી હોય છે. આ પાઇપ્સ ઝડપથી ફાટી જતી કે બગડી જતી અટકાવવા તેમને જમીનની અંદર દાટવામાં આવે છે.
