Growth stages of Pearl millet

Source: http://vasat.icrisat.org/crops/pearl_millet/pm_production/html/m2_2.3/index.html

The growth and development of pearl millet can be divided into 3 major stages.

Growth stage 1

               Growth Stage 1

 

The seedling establishment with root, leaf, and tiller development takes place during this phase. Panicle initiation also begins.

Growth satge 2

                 Growth Stage 2

 Growth Stage 2

 

Elongation of all the leaves, emergence of all tillers, floral initiation in tillers, and stem elongation takes place during this phase. The elongation of the panicle and formation of floral parts are found in this phase. This stage comes to end with the emergence of stigmas on the panicle.

Growth stage 3

                  Growth Stage 3

Growth Stage 3

This phase begins with fertilization of florets and continues up to maturity of the plant. The dry matter accumulation is mainly in grain formation and partly in the enlargement of stem and leaves of the tillers. The end of this phase is physiological maturity, indicated by the development of dark layer at the bottom of the grain.

These 3 growth stages are the averages for environmental conditions during June-September at Hyderabad, India (170 North latitude). Developmental rates are a function of the environmental conditions and the variety that is grown. The duration of growth stages may vary considerably for other locations and varieties.
