Economic Evaluation of Dry land and Irrigated Cropping Pattern in Jammu was conducted in the Jammu district of J&K state of India. Data was collected from the 200 sampled farmers from the four different blocks of the Jammu District with the help of pretesting schedule through personnel interviewing methods. The work was done on the resource use efficiency, cropping pattern, cost and returns in growing major crops (Paddy and wheat in Irrigated conditions and Wheat and Maize in dry land conditions) on the farm under irrigated and dry land situation. Various cost concepts were employed to explain cost and return structure. In order to study the relationship between output and various inputs, Cobb-Douglas production function was used. The instability in cropped area, yield and net returns were studied by calculating the coefficient of variation.
