Answer the following questions :
1) why irrigation is important for growing crops?
2) why traditional methods of irrigation are not adopted?
3) mention two advanced methods of irrigation and their best use of growing crops.
Answers
Answer:
1) It helps to cultivate superior crops with the water supply as per need of the crops. Ultimately it helps in economic development. Irrigation water improves water conditions in the soil, increases the water content of plant fibers, dissolves nutrients & makes them available to plants.
2) it needs more water and also more time and labour.
3)
Drip/trickle irrigation: Drip irrigation is most suitable for row crops (vegetables, soft fruit), tree and vine crops where one or more emitters can be provided for each plant
Sprinkler irrigation: Sprinkler irrigation is suited for most row, field and tree crops and water can be sprayed over or under the crop canopy. However, large sprinklers are not recommended for irrigation of delicate crops such as lettuce because the large water drops produced by the sprinklers may damage the crop.
Explanation
Answer:
1) Irrigation is the process of watering the plants plants need water to prepare their own food and to grow so what is needed for the growth of plant so thatirrihationis important for growing crops
Explanation:
2)Also called the pulley system, it involves pulling up water from a well or other such source to irrigate the land. It is an extremely time consuming and labour intensive system, but it is very cost efficient. Also, wastage of water is avoided when using a moat system of irrigation.
3)The necessity for water and the risks associated with inadequate sewage treatment have stimulated attempts to reuse domestic wastewater for diverse purposes, primarily for agricultural irrigation. This strategy has now become practical. The use of wastewater in small communities depends on a series of factors, such as community size, socio-economic aspects, relative location to other communities, and land availability for effluent reuse. Two main types of small and isolated communities can be identified. One has limited water supply and land resources, and its' main problems are associated with wastewater treatment and disposal. The second has enough land for effluent reuse, but lacks the additional amounts needed for cultivation. The extra amounts of effluent can be obtained from an adjacent municipality of the first type which, for its part, needs to solve wastewater disposal problems
