BACHELOR OF BUSINESS ADMINISTRATION

Detailed explanation-1: -A Tornqvist index is currently used to estimate agricultural productivity. In the past, the Laspeyres index, which uses base-period weights, was used in contrast to the Tornqvist, which uses prices from both the base period and the comparison period.

Detailed explanation-2: -The indicators measure the relationship between primary agriculture and the environment, thus excluding the agro-food chain (e.g. pesticide manufacturing, food processing) and the impact of changes in the environment on agriculture (e.g. impact of climate change on agriculture).

Detailed explanation-3: -Agricultural productivity is measured as the ratio of agricultural outputs to inputs. While individual products are usually measured by weight, which is known as crop yield, varying products make measuring overall agricultural output difficult.

Detailed explanation-4: -Productivity of land refers to the total output divided by the per unit area of land. Hence the productivity of land is measured to check the extent of efficiency.
