The measure of the amount of crop produced per unit of land.
📊
Crop yield is the amount of agricultural produce harvested per unit of land area, typically expressed in tonnes per hectare, kilograms per acre, or bushels per acre. It is a key indicator of farm productivity, food security, and the efficiency of inputs such as water, fertiliser, and labour. Yield is determined by genetic potential, climate, soil quality, water availability, pest and disease pressure, and management practices. Historical yield gains have been dramatic: global wheat yields roughly tripled between 1960 and 2020, largely due to the Green Revolution's high-yielding varieties, irrigation, and fertilisers. Yield gaps—the difference between potential and actual yields—remain large in many regions, particularly in sub-Saharan Africa and South Asia. Measurement involves weighing harvested grain or produce from a known area, and modern combines use yield monitors with GPS to map variability within fields. Improving yields sustainably is central to feeding a growing global population while reducing agriculture's environmental footprint.
