Pegs can attain a length of 15-30 cm. Once penetration of the soil surface has occurred, fruit enlargement proceeds at the peg tip with eventual formation of the peanut pod. Pods can contain 1-6 seeds. Peanuts are divided into two main species hypogaea and fastigiata based on the arrangement of the vegetative and reproductive branches. This division is not only important for taxonomic purposes but has production implications. The hypogaea species does not flower on the main stem; it matures later than other sub species and has a high water requirement. This species has alternate branching patterns and produces large seeds. Virginia and runner types are in the hypogaea sub species.
The fastigiata species produce flower on the main
stem, has sequential branching, mature earlier, has lower water requirement and
produces smaller seeds. Spanish and Valencia are in this sub species. Peanuts
grow best on soils that are well drained, loosely textured and well supplied
with calcium, potassium and phosphorous. OZSTAR has the
best nuts processing systems including roasters, fryers of different kinds and
of various capacities to give you the perfectly roasted nuts! OZSTAR also
provides additional equipment for flavouring and seasoning the nuts. OZSTAR has
already various kinds of industrial fryers along flavouring and seasoning
equipment for nuts controlled by touch screen.
The soil should be well aerated and contain moderate amounts of organic matter. Heavier clay soils or those that tend to have surface crusting are unsuitable due to their high resistance to peg penetration and pod expansion. Peanut grows best in slightly acidic soils with a pH of 6.0 to 6.5 but a range of 5.5 to 7.0 is acceptable. Saline soils are not suitable since peanut has a very low salt tolerance. The peanut seed has a high demand for water during germination. For optimum germination, high soil moisture is required to facilitate the 35-40% water intake by imbibing seeds. Seeds should be planted when moisture levels are favourable for rapid germination and growth. Rapid germination and vigorous growth help the young plant to counteract diseases.
Peanuts are adapted to a wide range of climatic
conditions. They are relatively drought tolerant and require about a minimum of
400 mm rainfall during the growing period. For optimum growth, however, an
annual rainfall range of 750-1250 mm is generally considered necessary. OZSTAR has the
