Step 1: Definition of Agronomy.
Agronomy is a branch of agricultural science that deals with crop production, soil management, and farming practices.
It combines various aspects of biology, chemistry, and environmental science to increase agricultural productivity.
Step 2: Contribution of Jethro Tull.
Jethro Tull is regarded as the father of Agronomy because he introduced scientific methods of farming.
He invented the seed drill in the 18th century, which allowed seeds to be sown in rows at proper depth and spacing.
This invention drastically improved crop germination and yield compared to traditional broadcasting.
He also emphasized the importance of tillage and soil management in crop production.
Step 3: Analysis of options.
- (A) Jethro Tull: Correct answer, father of Agronomy due to his contributions in modern farming techniques.
- (B) J.V. Liebig: Known as the father of Agricultural Chemistry for his work on plant nutrition and mineral theory.
- (C) Peter Discresezni: Not related to Agronomy significantly.
- (D) Molisch: Known for work in plant physiology, not Agronomy.
Step 4: Conclusion.
Hence, Jethro Tull is rightly considered the father of Agronomy.
