ABSTRACT
This chapter examines the national- and state-level changes and emerging regional patterns in area, production and yield of food grains and other crops. Spatial variability in agriculture growth ratios is mapped across different phases of economic planning. Changes in crop area and crop yield are also measured to capture growth dynamics of agriculture change. Finally, agriculture growth, which is the proportionate change in the total volume of agricultural output over time, is measured using the agriculture growth ratio (crop area growth ratio, crop yield growth ratio) and further validated through the Incremental Input Output Ratio (IIOR). Incremental agricultural output reflects the changes in agricultural production components by measuring the absolute size of output increase within a specific span of time. Understanding the absolute and proportionate change of various components of agriculture output is critical to analysing the key trends, changes and dynamics in agriculture growth patterns in India.
