A canal flowing at a rate of 150 liters/sec delivers 130 liters/sec of water to the field. An area of 2 hectares was irrigated in 8 hours. The effective zone of root depth is 1.7 m, available moisture holding capacity of soil is 20 cm per meter depth of soil, runoff loss in the field is 425 m³, and for healthy growth of the crop the moisture content must not fall below 50% of water holding capacity between field capacity and permanent welting point. Calculate the application efficiency (in percentage) by rounding it to the lower nearest integer.
