Abstract
Intensively managed irrigated rice of 3 varieties on a Vertisol typical of large areas in the tropics responded strongly to the application of 200 pounds of nitrogen per acre but not to phosphorus fertilization. Bluebonnet and Chontalpa varieties responded to the application of 200 pounds of potassium per acre, the Sinaloa variety to 300 pounds. All varieties responded strongly to the application of 40 pounds per acre of a complete minor element mixture.Downloads
