Rice Yield in Bags per Hectare by Irrigation

Rice Yield Calculator (bags per hectare with irrigation factor)

In Brazil, rice (Oryza sativa) yield gets counted in 60 kg bags per hectare. The base formula reads total_bags = area_ha × base_yield_bags_per_ha × irrigation_factor. That irrigation factor runs from 0.6, for upland fields under severe water stress, up to 1.3 for flooded paddies that are well managed.

Irrigated rice from the wetlands of Rio Grande do Sul, Santa Catarina and Tocantins brings in 6,500–8,500 kg/ha, roughly 110–140 bags. Upland rain-fed rice in Maranhão, Piauí and Mato Grosso barely reaches 2,000–3,000 kg/ha. Rio Grande do Sul on its own accounts for about 70% of the country's rice, and EMBRAPA and IRGA cultivars dominate the lowland fields around Pelotas. CONAB keeps tabs on the yearly harvest plans for flooded rice areas.

Applications

Reach for this calculator when you want to weigh an irrigated system against an upland one, estimate gross revenue per area, work out a flooding schedule in the várzeas, check how a cultivar is performing, or size up the storage you'll need when the harvest peaks.

FAQ

How heavy is one bag of rice? The standard commercial bag in Brazil holds 60 kg of paddy rice, that is, rice still in the husk.

How much more productive is irrigated rice? Flooded rice usually pulls in two to three times what upland rain-fed rice does, and it swings far less from one season to the next.

Which state leads Brazilian rice production? That would be Rio Grande do Sul, which puts out around 70% of the national total, most of it from the irrigated wetlands near Pelotas and the Lagoa dos Patos region.
