Phase 1


(Starting with sowing, sprouting till formation of cotyledonous leaves and, probably, two or three full-fledged leaves; soil surface is not covered or slightly covered with plants (canopy is less than 10%)

Phase 2


Crop development stage (from the beginning of quick growth till blossoming, when development rate slows down; by the end of the stage canopy is 70% - 80%)

Phase 3


Flowering stage or mid-season stage (includes the main period of blossoming and early phase of seed and fruit formation; from effective canopy 70% - 80% till start of fading and falling off

Phase 4


Ripening stage (when crop develops, ripens and harvest is collected)
