Dr. Derald G. Langham, (1913-1991) PhD (Cornell), was an agricultural geneticist, known as the "father of sesame" for his work on the basic genetics of sesame. He was the founder of the Genesa Foundation. Here he contends that vegetables and flowers planted in circles attract more solar energy and hence produce better crops than if they are planted in straight lines.... This technique has been tried successfully by the author and others and is the basis of his discovery of what he named Genesa principles.
