Abstract
A major increase in cotton area was observed in Gujarat, replacing by
groundnut in the Saurashtra region. As the agricultural production is subjected to
extent of variation, the growth and instability in agriculture has remained the subject
of deep concern in the area of agricultural economics in India and this is true for
oilseeds production also. Instability in agricultural production is also important for
agricultural product management. Hence, a critical analysis of growth and instability
of groundnut production have its own significant importance. Besides instability,
Indian agriculture is also known for sharp variations in agricultural productivity
across space which results in various types of disparities.
The present study has been taken up,
i. To study different statistical models for the growth in area, production and
productivity of groundnut crop in Gujarat.
ii. To measure the extent of variation in area, production and productivity of
groundnut crop in Gujarat.
iii. To examine the inter district inter region variability in area, production and
productivity of groundnut crop in Gujarat
The time series data on area, production and productivity of groundnut crop
for 31 years were collected for major groundnut growing districts and Gujarat state
ABSTRACT for the period 1985-86 to 2015-16 from Directorate of Agriculture, Gandhinagar,
Gujarat State. The entire study period was divided into two sub-periods on the basis
of introduction of Bt- cotton as pre Bt-cotton and post Bt- cotton. Various polynomial
as well as ARIMA model was used to study the growth. Instability in the area,
production and productivity of groundnut was analyzed using the Cuddy Della Valle
Index (CDVI) and Friedman test was used to study the inter district and inter regional
variability.
The results revealed that the area under groundnut was decreased in
Bhavnagar, Jamnagar, Junagadh, Kheda, Rajkot and Sabarkantha districts after
introduction of Bt-cotton. The production of groundnut was increased in Ahmedabad,
Banaskantha, Rajkot and Sabarkantha districts whereas decreased in Jamnagar district
and remained stable in Surat district after introduction of Bt-cotton. Productivity was
increased in Banaskantha, Bhavnagar, Jamnagar, Junagadh, Rajkot, Sabarkantha and
Surendranagar districts after introduction of Bt-cotton.
Majority of the districts showed medium level of variability for area except
Ahmedabad, Banaskantha, Kheda and Surat (High variability), Rajkot (Low
variability), all the districts showed high level of variability for production and high
level of variability for productivity except Kheda, Surat and Surendranagar which
showed medium level of variability. Significant variability was observed among
districts and regions with respect to area under groundnut, production and
productivity of groundnut.
