What’s the maximum yield of wheat with Sri?
Maximum wheat yield with SRI principles was 4.1 tons per acre (10.25 tons per hectare), > 3x the maximum yield with traditional methods (1.1 tons per acre). In Bihar, organic SWI has reached 5.43 tons/acre (13.57 t/ha). Wheat yields achieved with SWI methods The yields achieved show that SRI methods are better than the usual methods.
