The Directorate of Statistics & Evaluation,
Bihar (SASA) releases estimates area, production
and productivity in respect of principal crops
of food grains, oilseeds, sugarcane, fibers and
important commercial and horticulture crops.
These crops together account for nearly 31.9 %
at current prices 2004-05 of agriculture output.
The estimates of crop production are obtained by
multiplication of area estimates by
corresponding yield estimates. The estimated of
area and yield rates assure prime importance in
the entire of agricultural statistics.
Form the point of view of collection of area
statistics in Bihar. It has been cadastral
surveyed and where area and land
statistics are built up as a part of the
land records maintained by the revenue
agencies (referred to as "Land Record State"
or temporarily settled states). The system
of land records is followed in Bihar. In
Bihar account for about 86 % of reporting
area and is covered under Timely Reporting
Scheme(TRS) under which 20 % villages are
selected at random for complete area
The second most important component of
production statistics is yield rates. The yield
estimates of major crops are obtained through
analysis of Crop Cutting Experiments (CCEs)
conducted under scientifically designed General
Crop Estimation Surveys(GCES). At present over
95% of the production of food grains is
estimated on the basis of yield rates obtained
from the CCEs. The primary objective of General
Crop Estimation Survey (GECS) in to obtain
fairly reliable estimates of average yield of
which is important from the point of view of
crop production. The estimates of yield rates
thus arrived at are generally adopted for the
purposes of planning, policy formulation and
implementation. The crop cutting experiments
mental plots of a specified size and shape in a
selected field on the principle of random
sampling, harvesting and threshing the produce
and recording of harvested produce for determine
the percentage recovery of dry grains or the
marketable form of the produce.
Agricultural Directorate collects and compiles
data of Rainfall from IMD and field officers of
Commission for Agricultural Costs and Prices
(CACP). Agricultural Directorate also
consolidated answers to the set of questions set
in the questionnaire for formulation price
policy for various agricultural commodities.

Department also collects and compiles Crop
Damage Reports from DM/ JDA/ DAO.
