dc.description.abstractThe present investigations entitled “Effect of weather parameter on the production of mango and citrus in Una district of Himachal Pradesh” were conducted during 2019 – 2020 in the Department of Fruit Science, College of Horticulture and Forestry, Neri. Weather data for the period 1996 to 2018 and bimonthly (December – January) weather data from 2004 – 2018 and the data on fruit production for the period 1996 – 2018 with respect to Una district of Himachal Pradesh were analyzed. Spatial data were used for preparation of physiographic map of the district. Effect of weather parameters on fruit crop production were assessed using regression analysis whereby individual parameters were correlated with fruit production and the multiple linear regression equations were obtained. To compute the trends of weather parameters and variability analysis (mean, standard error, standard deviation, skewness and kurtosis), regression coefficient whereby different functions considering linear, logarithmic, inverse, quadratic, cubic, compound, power, s curve, growth and exponential functions were fitted and best fit equations were selected on the basis of R2 and RMSE. The results of variability analysis revealed no significant trend for weather parameters. Skewness and kurtosis did not follow any normality assumptions. In case of trend analysis, regression function (cubic and quadratic) were found best fit for weather parameters with highest value of R2 (0.48) in case of minimum temperature, while R2 varied from 0.04 – 0.36. The coefficient of correlation between maximum temperature and mango production showed positive correlation (r = 0.623) whereas, citrus production also showed positive significant correlation with maximum temperature (r = 0.855) at 1 % level of significance. The analysis of regression for fruit production, minimum temperature on citrus production was found significant with an R 2 value 0.21, indicating thereby that citrus production is influenced by minimum temperature but not weather parameters in combination. The physiographic maps used to identify the topographic situation with the help of DEM, slope, contour, aspect and hillshade maps. These maps are very useful for land use planning.en_US
