Which irrigation method delivers water directly to roots using emitters for optimal moisture control and efficiency?

कौन-सी सिंचाई विधि एमिटर (Emitters) की सहायता से सीधे पौधों की जड़ों तक पानी पहुँचाती है, जिससे नमी का सर्वोत्तम नियंत्रण और अधिक दक्षता प्राप्त होती है?

Options / विकल्प

A. Overhead Irrigation
ओवरहेड सिंचाई

B. Flood Irrigation
बाढ़ सिंचाई

C. Drip Irrigation
ड्रिप सिंचाई

D. Sprinkler Irrigation
स्प्रिंकलर सिंचाई


Correct Answer / सही उत्तर

C. Drip Irrigation (ड्रिप सिंचाई)


Detailed Explanation / विस्तृत व्याख्या

Hindi

ड्रिप सिंचाई (Drip Irrigation) एक आधुनिक सूक्ष्म सिंचाई (Micro-Irrigation) प्रणाली है, जिसमें पाइपों और एमिटरों के माध्यम से पानी को सीधे पौधों की जड़ों तक बूंद-बूंद पहुँचाया जाता है।

इस विधि की मुख्य विशेषताएँ:

  • पानी सीधे जड़ क्षेत्र (Root Zone) में पहुँचता है।
  • वाष्पीकरण (Evaporation) से होने वाली जल हानि कम होती है।
  • जल उपयोग दक्षता 90% या उससे अधिक हो सकती है।
  • खरपतवार (Weeds) की वृद्धि कम होती है।
  • उर्वरकों को पानी के साथ देने (Fertigation) में सहायक है।
  • जल की कमी वाले क्षेत्रों के लिए अत्यंत उपयोगी है।

फल, सब्जियाँ, बागवानी फसलें तथा ग्रीनहाउस में इसका व्यापक उपयोग किया जाता है।


English

Drip Irrigation is a modern micro-irrigation system in which water is delivered directly to the root zone of plants through a network of pipes and emitters.

Key features include:

  • Direct water application to plant roots.
  • Minimal water loss through evaporation.
  • Water-use efficiency often exceeds 90%.
  • Reduced weed growth.
  • Suitable for fertigation (applying fertilizers through irrigation water).
  • Highly effective in water-scarce and arid regions.

It is widely used for orchards, vegetables, horticultural crops, and greenhouse cultivation.


Why Other Options Are Incorrect / अन्य विकल्प गलत क्यों हैं?

A. Overhead Irrigation (ओवरहेड सिंचाई)

  • Water is sprayed from above.
  • More water is lost through evaporation and wind drift.

B. Flood Irrigation (बाढ़ सिंचाई)

  • Entire field is flooded with water.
  • Large amount of water is wasted through seepage and evaporation.

D. Sprinkler Irrigation (स्प्रिंकलर सिंचाई)

  • Water is sprayed like rainfall.
  • More efficient than flood irrigation but less efficient than drip irrigation.

Important Facts / महत्वपूर्ण तथ्य

  • Drip irrigation is also called Trickle Irrigation.
  • It was popularized by Simcha Blass of Israel.
  • It is considered the most water-efficient irrigation method.
  • Particularly useful in dry and semi-arid regions.
  • Widely promoted in India under the Pradhan Mantri Krishi Sinchayee Yojana (PMKSY).

One-Liner / एक पंक्ति में

Drip irrigation delivers water directly to plant roots through emitters, making it the most efficient irrigation method.

ड्रिप सिंचाई एमिटरों के माध्यम से सीधे जड़ों तक पानी पहुँचाती है, इसलिए यह सबसे अधिक जल-दक्ष सिंचाई विधि मानी जाती है।
