Abstract

The effect of development stage on the chemical composition of oats was determined under conditions of constant temperature, humidity and light. The changes in composition as a function of age were found to be small for K, Na, Ga and Mg but considerable in the case of N and P. In addition, a study was made of early diagnosis of mineral deficiencies by means of chemical analysis, oats being used as the test crop. The data were obtained from 18- and 25-day-old plants growing in sand cultures from which varying amounts of N, P, K or Mg were omitted. It was concluded that early diagnosis is possible provided that the fluctuation in chemical composition of normal plants is known. The rapid changes in chemical composition of crops in the field are most probably due to fluctuating concentrations of ions in the soil solution and not to small differences in stage of development.
