MCQ (Single Correct) +1 −0.33

Who is the father of Indian Soil Science and Agricultural Chemistry?

भारतीय मृदा विज्ञान और कृषि रसायन के पिता कौन हैं?

V.V. Dokuchaev वी.वी. डोकुचेव J.W. Leather जे.डब्ल्यू. लेदर J.V. Liebig जे.वी. लीबिग J. Thomas जे. थॉमस

Dr. J. Walter Leather is universally recognized as the Father of Agricultural Chemistry and Soil Science in India.
He was appointed as the Agricultural Chemist to the Government of India in 1892 (conducting initial work in Dehradun and Kanpur), and subsequently served as the first Imperial Agricultural Chemist upon the founding of the Imperial Agricultural Research Institute at Pusa (Bihar) in 1906.
He conducted pioneering research on water requirements of crops, soil moisture conservation, and saline/alkali soils of India.
J.W. Voelcker authored the 1891 report 'Improvement of Indian Agriculture', while Norman Borlaug pioneered dwarf wheat.

Hence, the correct option is (B).

डॉ. जे. वाल्टर लेदर (J. Walter Leather) को भारत में कृषि रसायन एवं मृदा विज्ञान का जनक माना जाता है।
उन्हें 1892 में भारत सरकार का कृषि रसायनज्ञ नियुक्त किया गया था और बाद में 1906 में पूसा (बिहार) में इम्पीरियल एग्रीकल्चरल रिसर्च इंस्टीट्यूट की स्थापना पर वे देश के प्रथम इम्पीरियल कृषि रसायनज्ञ बने।
उन्होंने फसलों की जल मांग, मृदा नमी संरक्षण तथा भारत की लवणीय व क्षारीय मृदाओं पर ऐतिहासिक शोध कार्य किया।
जे. डब्ल्यू. वोएल्कर ने 1891 में भारतीय कृषि सुधार पर रिपोर्ट दी थी, जबकि नॉर्मन बोरलॉग हरित क्रांति के जनक थे।

अतः सही विकल्प (B) है।
