dc.description.abstractPresent investigation was carried out in different taluks of Dharwad district to study the impact of weather parameters on rain fed crops by using multivariate analysis. Secondary data on area, production and weather parameters viz., rainfall, temperature and relative humidity were collected from different sources. Among the different models, polynomial models were found to be suitable for weather parameters for all the taluks of Dharwad district. The Mann-Kendall test was used to study the trend of weather parameters. In case of rainfall, though on an average July month receives the maximum rainfall, distribution of rainfall is such that it slowly declines till mid of October. July peak reduced in last decade. For temperature though on an average all most all months received maximum temperature, July month experienced increased trend in last decade. Multiple linear regressions indicated that only area and rainfall were contributing significantly to the production of rain fed crops, but relative humidity was also contributing significantly to the production of Paddy crop in case of Dharwad taluk. The transitional probability matrix were depicted a broader idea of change of the direction of area over a period of last twenty years. It was revealed that the retention of area was almost similar for all the selected crops in Dharwad taluk except Sorghum crop which noticed highest retention of area in case of Hubli, Kundagol and Navalgund taluks and Paddy crop had maximum retention of area in Kalaghatgi taluk. The highest direct effect was productivity and rainfall in case of Dharwad and Navalgund taluks. Highest direct effect was rainfall and maximum indirect effect was temperature in Hubli and Kalaghatgi taluks.en_US
