Timely information is one
of the basic requisites for planning and management. Hence management &
planning for the public delivery system relating to foodgrains as well as
marketing of agricultural products, requires timely information of cropped area
and its yield. Considering this, Govt. of India has taken up a project entitled
"CROP ACREAGE & PRODUCTION ESTIMATION " using satellite data for
forecasting of acreage and yield of different crops before harvesting.
Traditional approach for estimation of acreage & yield is time consuming
& this is available only after harvesting.
In the state of West
Bengal, the approach of forecasting of acreage & yield for kharif rice,
mustard and potato using this technique has been introduced in the year 1993.
Since then the aus, aman during kharif and mustard, potato during rabi have been
estimated during different type of satellite data viz. Optical and microwave
data. This study shows that this technique is useful not only for forecasting
but monitoring the conditions of crops. This information may also be useful for
adopting a sustainable agriculture policy in West Bengal.
