Question

In a drip irrigation system water is irrigated drop by drop directly at the ____ of the crop through drippers set in small plastic tubes
(a)Root system
(b)Shoot system
(c)Leaf system
(d)Venation system

Answer 1

Hint: Drip irrigation is the most efficient water and nutrient delivery system for growing crops. It delivers water and nutrients directly to the plant's absorptive zone, in the right amounts, at the right time.

Complete answer:
Drip irrigation delivers water and nutrients directly to the plant’s root system. Drip irrigation is a type of micro-irrigation system that has the potential to save water and nutrients by allowing water to drip slowly to the roots of plants, either from above the soil surface or buried below the surface. Drip irrigation systems distribute water through a network of valves, pipes, tubing, and emitters. Water and nutrients are delivered across the field in pipes called ‘dripper lines’ featuring smaller units known as ‘drippers’. Each dripper emits drops containing water and fertilizers, resulting in the uniform application of water and nutrients directly to each plant’s root zone, across an entire field. Higher consistent quality yields.

Additional Information: - When compared to other types of irrigation such as flood or overhead sprinklers since water can be more precisely applied to the plant roots. In addition, drip can eliminate many diseases that are spread through water contact with the foliage.
-Finally, in regions where water supplies are severely limited, there may be no actual water savings, but rather simply an increase in production while using the same amount of water as before.
-In very arid regions or on sandy soils, the preferred method is to apply the irrigation water as slowly as possible.
So, the correct answer is the 'Root system'.

Note: -Drip irrigation is advantageous to Plants in many ways. It helps in water savings; there will be no evaporation, no runoff, no waste.
- It ensures 100% land utilization – drip irrigates uniformly in any topography and soil type. Energy savings: drip irrigation works on low pressure.
-It helps in efficient use of fertilizer and crop protection, with no leaching. Less dependency on weather, greater stability, and lower risks. High availability of water and nutrients. Avoids high salinity caused by excessive fertilizer application. No wetting of foliage that can result in fungal diseases.
