Crop yield

Crop yield refers to the measure of the output of a crop per unit area of land cultivation, and it’s a critical factor in agricultural productivity. In the context of cannabis, crop yield is significant for both commercial and personal growers, as it determines the volume of cannabis produced.

Crop Yield Measurement and Historical Trends

• Crop yield is measured in kilograms per hectare or bushels per acre.
• Historical cereal yields in the UK: 500kg/ha in Medieval times, 2000kg/ha in the Industrial Revolution, and 8000kg/ha in the Green Revolution.
• Technological advances increase crop yield and reduce ecological footprint.
• Yields and agricultural productivity are related but not synonymous.
• Factors like expensive fertilizers can impact profitability despite higher yields.

Seed Multiplication Ratio and Agricultural Advancements

• The seed multiplication ratio is the ratio of seed investment to yield.
• A ratio of 1:3 is considered minimum for sustaining human life.
• Seed ratios historically varied, improving over time with agricultural advancements.
• In Europe, the seed ratio improved from 1:2.5 to 1:14 with crop rotation.
• The Indian Council of Agricultural Research recommended revisions in 2018.

Law of Physiological Relations and Crop Yield Optimization

• Alexander Mitscherlich’s 1909 study led to the Law of Physiological Relations.
• The law relates plant food quantities to crop yield.
• Concepts like Liebig’s Law of the Minimum and Blackman’s limiting factors are related.
• The law is expressed as a logarithmic function showing diminishing returns.
• The relation was reviewed by Hans Schneeberger in 2009.
