Pigeon pea grows as a perennial plant,
but is cultivated as an annual or biennial
crop. It is a much branching woody
shrub and grows to a height of four meters.
The branches spread upto two meters.
The flowering period varies from 65 to
200 days, the early selected cultivars generally
maturing in 120-130 days. Arhar is a tropical crop and most
adapted to drought conditions. Soil fertility
not being a limiting factor, it can be
grown on marginal to low fertility land
(Gowda and Kaul 1982). Due to the ageold
system of cultivation, less than a ton
of Arhar seeds per hectare is available
from about 3600 ha of land -under Arhar
