The average yield of sugar beet crops worldwide was 60.8 tonnes per hectare. [21] The most productive sugar beet farms in the world, in 2022, were in Chile, with a nationwide average yield of 106.2 tonnes per hectare. [21] Imperial Valley (California) farmers have achieved yields of about 160 tonnes per hectare and over 26 tonnes sugar per ...
Along with climate and corresponding types of vegetation, the economy of a nation also influences the level of agricultural production. Production of some products is highly concentrated in a few countries, China, the leading producer of wheat and ramie in 2013, produces 95% of the world's ramie fiber but only 17% of the world's wheat. Products ...
This article includes the table with land use statistics by country.Countries are ranked by their total cultivated land area, which is the sum of the total arable land area and total area of permanent crops.
Coffee harvest in Ethiopia. Coffee, which originated in Ethiopia, is the largest foreign exchange earner. Agriculture accounted for 50% of GDP, 83.9% of exports, and 80% of the labor force in 2006 and 2007, compared to 44.9%, 76.9% and 80% in 2002–2003, and agriculture remains the Ethiopian economy's most important sector.

Beets are one of the most boron-intensive of modern crops, a dependency possibly introduced as an evolutionary response its pre-industrial ancestor's constant exposure to sea spray; on commercial farms, a 60 tonne per hectare (26.8 ton/acre) harvest requires 600 grams of elemental boron per hectare (8.6 ounces/acre) for growth.

Per hectare per year, the biomass produced corresponds to 0.27 TJ. This is equivalent to 0.86 W per square meter. Assuming an average insolation of 225 W per square meter, the photosynthetic efficiency of sugar cane is 0.38%. The 135 kg of sucrose found in 1 ton of b&c are transformed into 70 litres of ethanol with a combustion energy of 1.7 GJ.
For example, average yields of corn (maize) in the US have increased from around 2.5 tons per hectare (t/ha) (40 bushels per acre) in 1900 to about 9.4 t/ha (150 bushels per acre) in 2001. Similarly, worldwide average wheat yields have increased from less than 1 t/ha in 1900 to more than 2.5 t/ha in 1990.
In 2017 the yield per hectare was 15.5 tonne, or about € 4000 per ha for the farmer. In 2018 the beet suffered from draught and the harvest was much smaller. [ 19 ] To make matters worse, the world sugar price hit a 10-year low in 2018.
