Law of minimum was given by Liebig. It states that when a process, such as growth, is governed by a number of separate factors, the rate of the process is limited by pace of slowest factor.
Blackman' (1905) extended the law of minimum to formulate the law of limiting factors which in his own words is when a process is conditioned as to its rapidity by a
number of separate factors, the rate of the process is limited by the pace of slowest factor.
Calvin (1954) (Nobel Prize winner) traced the path of carbon in photosynthesis.
Amon (1960) demonstrated cychic and non-cyclic photophosphorylation.
