B Nutrient index पोषक तत्व सूचकांक (Nutrient index) II Stanley A. Barber स्टेनली ए. बार्बर
C Root interception जड़ अवरोधन (Root interception) III Liebig लीबिग (Liebig)
D Weathering index अपक्षय सूचकांक (Weathering index) IV Parker पार्कर (Parker)
EXPLANATION Historical Evolution, Agricultural Education and Research Infrastructure in India

Matching concepts with their pioneering scientists:

  • Justus von Liebig established mineral plant nutrition and is hailed as the 'Father of agricultural and fertilizer chemistry' -> (III).
  • F.W. Parker et al. (1951) proposed the Nutrient Index concept to categorize fertility status of soils -> (IV).
  • Stanley A. Barber formulated the mechanistic nutrient uptake model delineating root interception, mass flow, and diffusion -> (II).
  • M.L. Jackson (1948) developed the classic weathering stages and chemical weathering index of clay-sized minerals -> (I).
Thus, the correct match is (A)-(III), (B)-(IV), (C)-(II), (D)-(I).

वैज्ञानिकों और उनकी अवधारणाओं का सही मिलान:

  • उर्वरक रसायन विज्ञान के जनक: जस्टस वॉन लीबिग (Justus von Liebig) -> (III)।
  • पोषक तत्व सूचकांक (Nutrient index): एफ.डब्ल्यू. पार्कर (Parker, 1951) -> (IV)।
  • जड़ अवरोधन (Root interception): स्टेनली ए. बार्बर (Stanley A. Barber) -> (II)।
  • अपक्षय सूचकांक (Weathering index): एम.एल. जैक्सन (M.L. Jackson) -> (I)।
अतः सही मिलान (A)-(III), (B)-(IV), (C)-(II), (D)-(I) है।
