Prediction of area and production along with production function for area, production and productivity of linseed crop in undivided bastar region of Chhattisgarh

Abstract

Bastar region comes under Bastar plateau, agro climatic zone of Chhattisgarh. In the present study, an attempt has been made to study the predictive models for area and production of linseed crop in undivided Bastar region of Chhattisgarh. Time series data for the period from 1983-84 to 1997-98 on linseed were utilized for the study. The predictive model under study included a unique feature of structural periodic effect as a factor to capture the cyclic pattern, if any, along with trend effect in the time-series data. This periodic effect was estimated for area and production of the linseed. Apart from this model as a first case, wherein 4-year periodic cyclic effect is assumed along with annual effect working within it as a nested effect; another model has also been assumed with an overall periodic effect variable in combination with overall trend effect variable without any nesting, for comparison with the first case. Additionally, influences of area and productivity of the crops were also worked out to understand the impact of influencing factor (either area or) on the production of linseed.
