The groundnut belongs to the pea and bean family and is a legume. Groundnut is the third largest oilseed produced in the world and second largest in India. India occupies the second position in terms of production and first in terms of area.The country has exported 509664.85 million tones of groundnuts to the world for the worth of Rs. 3,187.69 crores during the year 2013-14.
It is necessary to dig the pods at the right time for obtaining higher yields of pods and oil. Nut takes two months to attain full development.A fully mature pod will be difficult to split easily with finger pressure. This stage is achieved when vine begins to turn yellow and leaves start shedding. Harvesting should be done when good percentage of nuts is fully developed and fairly intact.
The harvesting time of the crop is mainly in September & January.
Packaging & Storage
Like most other agriculture crops, groundnuts are semi perishable and their quality during storage can be deteriorated through microbial proliferation, insect and rodent infestation, loss flavors, viability and rancidity due to biochemical changes as well as absorption of certain odors and chemicals. Although clean and sound groundnuts can be stored for several years under suitable storage conditions, serious losses in milling quality may result when groundnuts are dried below 7% seed moisture content. The studies indicated that the unshelled ground nut in bulk could be stored best at about 7.5% seed moisture content at 100C.At these storage conditions, good quality unshelled groundnuts can be stored for at least one storage season (about 10 months) without significant loss in quality.
