Crop Establishment

  • Crop establishment is the establishment of seeds or seedlings in the field in order to obtain a successful crop with an optimum potential yield.
  • Two main methods are practiced in Sri Lanka (extent of crop established with each method is given in Table 1).
  • The choice of the method of establishment depends on factors such as,
    • “age” of the variety
    • soil moisture level
    • climatic conditions
    • availability of inputs and labor
