Abstract: The present investigation was conducted in Jammu district of Jammu and Kashmir state during the year 2008. Two blocks were selected from Jammu district having the highest area under the ber fruit. Cobb-Douglus function was used to study the relationship between output and various inputs. The inputs involved in the production of ber cultivation varied significantly at different age groups. The regression coefficient values of selected inputs mainly human labour, manures + fertilizers, plant protection and pruning + training varied significantly at the six age groups of five years from 5^th to 28^th year. The coefficient of variation was highest in case of area, whereas it was low in case of yield and net returns.
