Abstract

The purpose of the data upon which this paper is based is to show:

1. The relation of the various environmental factors to the composition of the ripened grain.

2. Whether nutritional conditions of the plant, as manifested in the physical properties and the protein content of the grain, can even under identical climatic influences be affected to a marked degree by the fertility of the soil.

3. That the correlation of low protein content of the grain to deficient nutritional conditions is indicative as to the cause for the occurrence of mealiness in the kernels of hard wheats, a condition most commonly designated as “Yellow Berry.”

4. That the lack of sufficient available nitrates during the period of growth and development of the plant, especially during the period of kernel-formation and elaboration, is more closely correlated to the prevalence of yellow berry than the ratio of available nitrogen to the potassium content of the soil.
