Trend study of Meteorological Parameters and Crop Yield in Solan District of Western Himalayan State
Journal Title: Universal Journal of Environmental Research and Technology - Year 2014, Vol 4, Issue 4
Abstract
The study was carried out to examine the trends of important weather parameters and their effect on the production of cereal crops in Solan district of Himachal Pradesh. The descriptive statistics and regression analysis revealed no significant trend in all the selected weather parameters in annual, seasonal and monthly basis for the period (1984 – 2011). In Regression analysis cubic and quadratic functions (non significant) were found to be the best fit. Sen’s estimation analysis indicated increasing trend of maximum temperature by 2.95oC, minimum temperature by 0.50oC and decreasing trend of rainfall, relative humidity and sunshine hours. Analysis of relationship of crop yields to time in regression analysis did not show any significant trend. However, Sen’s estimate showed increasing trends for selected crops. There was no significant correlation of individual weather parameters with crop yields but in case of multiple regression analysis some effects were observed indicating thereby that crops yields are influenced by combinations of weather parameters.
