Pepper

Botanical Name: Piper nigrum              Family: Piperaceae

Cultivation and Harvesting :

Black pepper is popularly known as the ‘King of Spices’ and mainly cultivated in the southern parts of India. India is a major producer, consumer and exporter of black pepper

Black pepper belongs to the family Piperaceae, is one of the most popular spices used worldwide and is native to southern India. The name “pepper” originated from the Sanskrit word “Pipali”.

Black pepper can be cultivated either as a mono-crop or as a mixed crop.

Black pepper is a plant of humid tropics requiring high rainfall and humidity. The hot and humid climate of sub mountainous tracts of Western Ghats is ideal for its cultivation. The crop tolerates temperatures between 10°C and 40°C. The favourable temperature range is 23°C.  - 32°C. and the ideal temperature is around 28°C.

Planting of Cuttings: Ideal time for black pepper planting is at the onset of south-west monsoons. Training and Pruning of Vines: Training of vines on the support trees is highly recommended as it facilitates the energetic growth of the fruit-yielding branches. Major purpose of this practice is to remove excessive growth of the live standards and to give them a proper shape.

Irrigation: Frequent irrigation from November - December till the end of March is recommended and afterwards, irrigation must be withheld till monsoon break. This may increase pepper yield by about 50%.

Major Products: The major products are black pepper, white pepper, canned tender green pepper, bottled green pepper in brine, dehydrated green pepper, pepper oleoresin and pepper oil.

Morphology of plant:

1.Black pepper is a perennial climbing vine that grows well in the shade with supporting trees or poles.

The plant has 10–20 primary adventitious roots developed from the base of the mature stem. The glabrous woody climbers grow up to 10 m or more height.

2.The vine has two types of branching called as dimorphic branching.

3.The orthotropic vegetative (monopodial, orthotropic branches) climbing shoots bears numerous adventitious roots, leaves and axillary buds at the swollen nodes, the roots enabling the plants to cling to tree trunks and other supports. The lateral plagiotrophic (sympodial fruiting branches) fruiting branch developing from axillary bud does not have roots.The orthotropic shoot has indeterminate growth, and leaf axils produce lateral fruiting branches.

4.The leaves are alternate ovate with sharp pointed ends and arranged alternately on the branches, leaves are dark green, shining above and pale green.

5.The inflorescence is pendulous spike arises opposite to leaves on plagiotropic branches. Wild type flowers are mostly dioecious, but the cultivated type flowers are monoecious. The flowers are partially enclosed within a bract. Each spike bears 50 to 60 single seeded fruit.

6.The fruit is indehiscent drupes also known as peppercorns. These are circular in shape and about 4-6mm in diameter. The colour of the berries changes to red on maturity. Each berry possesses a single seed enclosed in a pericarp. The embryo is embedded in a small endosperm at the apex of the seed
