Unformatted text preview: high-protein livestock feed and as a fertilizer.
The dry pericarp of the mature pods (known as shells or husks) is used for fuel, as a soil
conditioner, filler in fertilizers and feeds, or is processed as substitute for cork or hardboard
or composting with the aid of lignin decomposing bacteria. 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.
