Description The statistical investigation of impact of climate on chilli yield in Dharwad, Gadag
and Haveri districts was conducted based on secondary data of Chilli yield (1998-2010),
obtained from Directorate of Economics and Statistics, Government of Karnataka, Bangalore
and the weather parameters (1995-2012) were obtained from Assistant executive water gauge
office sub-division-2, Dharwad. Different statistical techniques such as, correlation analysis,
trend analysis, Mann-Kendall test, stepwise regression analysis and spatial lag models were
employed for drawing inference.
An effort is made to build the suitable models for the trend of weather parameters by
using different statistical models. The cubic model was found to be significant and best
suited for the trends of rainfall, temperature and relative humidity of selected districts,
followed by quadratic model. The results of Mann-Kendall test indicated that most of the
months showed no trend for rainfall, temperature and relative humidity of Dharwad district,
whereas relative humidity of Gadag and Haveri districts, showed an increasing and
decreasing trend respectively in most of the months. Stepwise regression models have been
employed to know the association between Chilli yield and weather parameters. There was a
positive significant effect of rainfall on chilli yield in Dharwad district. In case of Gadag
district, the minimum temperature had negative significant impact on yield, whereas in
Haveri district, the maximum temperature and minimum relative humidity had negative
significant impact. The spatial dependence of the Chilli yield on weather parameters of
Dharwad, Gadag and Haveri districts were observed and concluded that neighboring district
weather parameters were directly or indirectly affect the yield of Chilli in the selected
districts. In the present scenario of climate change the spatial analysis would serve as a
strategic tool for predicting the yield levels of targeted crops.
