Coffee Yield in Bags per Hectare

Coffee yield in bags per hectare: how to read productivity in the field

A standard coffee bag holds 60 kg of processed beans. To get yield in bags per hectare you take the harvested mass in kilograms, divide by 60, and then divide that by the area in hectares. In Brazil the arabica average sits at 30–35 sc/ha. Conilon (robusta) climbs to 50–70 sc/ha, and densely planted irrigated arabica can push past 60–80 sc/ha. Minas Gerais leads national output, with the Sul de Minas region out front. One quirk of coffee is its strong biennial rhythm: a heavy crop one year is normally followed by a lighter one, what growers call carga and contracarga. Take a 20-hectare lot that brings in 700 sacas, and you land on 35 sc/ha. The cultivar (Catuaí, Mundo Novo, Catucaí), how the trees are pruned, irrigation, and how much it rains during flowering will all nudge that number one way or the other.

Applications

Comparing your numbers with Conab safra forecasts, setting sale prices through cooperatives such as Cooxupé and COCAPEC, qualifying for specialty-coffee programs like BSCA, hedging on ICE Futures, applying for rural credit or crop insurance, deciding which year to prune and how to fertilize, and working out the economics of cost per bag.

FAQ

Why such a big gap between arabica and conilon yields? Conilon (robusta) is the more vigorous plant, it copes with heat, and in Espírito Santo and Rondônia it's usually irrigated. Arabica, on the other hand, grows in higher and cooler regions where its physiological ceiling is simply lower.

What causes the biennial cycle? A heavy fruit load drains the plant's reserves, so the next year it sets fewer rosettes and fewer beans. Pruning and irrigation can take some of the edge off that swing.

How much can dense irrigated arabica deliver? Adensado irrigado lavouras in the Cerrado Mineiro and Bahia clear 60–80 sc/ha on a regular basis, and some pilot plots have gone past 100 sc/ha.

How does Brazilian yield affect global prices? Brazil grows roughly a third of the world's coffee, so a frost or a drought here shows up almost at once in ICE Futures arabica and robusta contracts.
