The foliage of the crop also serves as silage and forage. With the recent thrust on bioenergy, possibilities are being tested for using groundnut as a bio-diesel crop, because groundnut produces more oil per hectare than any other food crop. 5. Growth and Development of Groundnut 5.1. Growth Stages The growth stages of groundnut plants based on visual observations of vegetative and reproductive growth have been described and defined by Boote (1982). This widely adopted system describes a series of vegetative (V) and reproductive stages (R), and all stages are discrete population-based events which are mostly determined by field observations (Table 1). Different reproductive stages of groundnut are shown in Figure 1.
