Dr. Shastry

Developed Jaya, the first dwarf rice variety in India, which helped in improving yields.

Law of Minimum

J.V. Liebig (1840)

Proposed the Law of Minimum, explaining how plant growth is limited by the most limiting factor in the environment.

Law of Limiting Factor

Blackman (1905)

Developed the Law of Limiting Factor, suggesting that growth is controlled by the factor in shortest supply.

Increase Yield N Low

Wilcox (1929)

Demonstrated the relationship between nitrogen levels and increased yield when other factors are limiting.

Leaf Area Index

Watson (1947)

Introduced the concept of Leaf Area Index (LAI), which is a key indicator of photosynthetic potential in plants.

Nutrient Mobility Concept

Brays R.H.

Concept of nutrient mobility, highlighting the movement of nutrients in the soil and their availability to plants.

“A” Value Concept for Phosphorus

Dean & Friend

Developed the “A” value concept, which assesses phosphorus availability in soils.

Harvesting Index

Donald

Introduced the Harvesting Index, measuring the proportion of biomass that can be harvested as crop yield.

Photoperiodism Concept

Gardner & Allard (1920)

Developed the concept of photoperiodism, studying the effect of day length on plant growth and flowering.

Thermoperiodism

F. Went

Introduced the concept of thermoperiodism, explaining how temperature variations affect plant growth.

Vernalization

Lysenko

Contributed to the understanding of vernalization, where cold treatment is required for flowering in certain plants.

S.N. Winogradsky

Father of soil microbiology, contributing to the study of microorganisms in soil ecosystems.

Agricultural Chemistry

J.V. Liebig

Father of agricultural chemistry, known for his work on the theory of plant nutrition and the Law of Minimum.
