Abstract
In India, Karnataka stands second in area (419 thousand hectare)
and third in production (1492 thousand million nuts) of coconut. In
Karnataka, Tumkur is the largest producer of coconut with the
production of 9945.66 lakh nuts (2010).
An attempt is made to study the area, production and productivity
of coconut crop in districts of Karnataka. The analysis is based on
secondary data taken from Directorate of Economics and Statistics,
Karnataka for the period 1982-2009. The results establish an increasing
shift of coconut cropped area (130.14%), production (203.65%) and
productivity (112.71%) for the period 1982-2009.
Three models viz., Linear, power and exponential were fitted for
comparison based on R2 value reveals that 5 districts indicating power
model and 9 districts showing exponential model for area. Three districts
with power model and 6 districts with exponential model as best fit for
coconut production.
Three indices have been used, viz., Herfindhal-Hirschman’s index,
Instability index and sustainability index of area and production of
coconut crop. The Hirschman’s index showed highest in Tumkur followed
by Hassan and Chitradurga district revealing the higher specialization for
the period 1982-2009. Instability index was found to be the least in
Tumkur as compared to Chitradurga and Hassan district. Highest
sustainability noticed in Tumkur followed by Chitradurga and Hassan
district during 1982-2009 in both area and production. To study the
temporal variability, regression analysis with maximum R2 noticed in
Tumkur, Hassan and Chitradurga districts for the periods in both area
and production.
