“…Wamser et al (2012) studied the productivity of tomato hybrids in super-high-density cultivation fields (44,444 plants ha -1 ), reporting a maximum yield of 170.7 t ha -1 , whereas in traditional cultivation (22,222 plants ha -1 ), the maximum yield was 128.5 t ha -1 . Assuming that the proportion of 36.5 % proposed by Bettiol et al (2004) is correct, yields of 62.2 and 46.9 t ha -1 should be expected for super-dense and traditional cultivation, respectively, under an organic cultivation system. Therefore, the maximum yield obtained in the present work, 53 t ha -1 , falls in the expected range for organic system.…”
