abstract
The present investigation was undertaken to study the “Performance and Instability Analysis of Potato-Chickpea Sequence Cropping System under Organic Production”. Secondary data of Potato-Chickpea sequence cropping system equivalent yield was collected from Institute of organic farming, Dharwad from the year 2004-05 to 2012-13. Coppack’s instability index, compound annual growth rate and CV were the statistical tools used for the analysis of instability and growth rate. The results from the analysis showed that yield of Potato-Chickpea cropping system was highly instable under integrated production system (61.09%) as compared to organic (57.19%) and inorganic production system (48.78%). Potato-chickpea integrated production gave higher yields over the years. The compound annual growth rate was found to be highest in organic production system followed by integrated and inorganic production system.
