摘要:
Grain sorghums were grown in field plots for three years. Soils were varied greatly in P, K, and pH and resulted in wide yield variation. Information from plant sample analyses at four growth stages was plotted individually against grain yield measurements. The diagrams were employed to estimate normal nutrient levels for each stage of growth. Low deficient, and high values are outlined as far as possible. Effects of climatic conditions are discussed.
