Abstract
The present study entitled "Short and long
term projections of area, production and productivity
of groundnut in Andhra Pradesh" has been attempted to
measure the growth rates and to estimate short term
projections from 1986-87 to 1994-95 and long term
projections from 1995-96 to 1999-2000, with a view to
provide certain guidelines for policy implications
which would bring balanced agricultural development.
The investigation was carried out for all
districts, regions and Andhra Pradesh state as a whole.
An attempt had also been made to assess the growth in
area, production and productivity of groundnut. Five
formulae viz., three linear and two multiple regression
models were tried . Formulae having maximum R2
values were used for projection purpose. Out of these
exponential function was used for long term projections
and the multiple regression model involving standard
deviations of groundnut prices as one variable was used
for short term projections.
for the
1985-86.

The secondary data was collected and analysed
period of 30 years covering from 1956-57 to
Almost all the Rayalaseema districts and some
districts showed positive growth in area,
production and productivity but negative in most of the
Telangana districts.
Short term projections of area, production and
productivity declined in most of the districts but long
term projections showed increasing trends
