ABSTRACT
titled TREND ANALYSIS AND
FORECASTING IN AGRICULTURE FOR SELECTED CROPS IN ANDHRA
PRADESH was undertaken for the period from 1956-57 to
1985-86 for the three regions of the state, namely,
Coastal Andhra, Rayalaseema and Telangana and also for
the state of Andhra Pradesh as a whole. The crops
selected were rice, jowar and bajra.Two types of functions, i.e., polynomial and
exponential were considered for analysing the trends in
area, production and ~roductivity of the three selectad
crops. The method of selection of polynomials of the
appropriate degree was described and polynomial
functions of upto fifth degree were considered for this purpose. Further screening from .the selected
polynomials and exponential functions was done based on
the corresponding error mean sums of squares. As a
result, exponential functions were selected for only
five of the parameters and polynomials were selected f'o r
the remaining parameters.The method of interval estimation was found
satisfactory when these intervals were estimated for the
observed values, i.e., for intrapolation. The
polynomial functions were found unsatisfactory for
extrapolation purpose compared to the exponential
functions. The range of intervals estimated was found
smaller with the method given by Rao and Kulkarni (1988)
compared to the general method hitherto used in
literature.
