GRANGEIRO, Leilson C et al. Yield of sugar beet and rocket depending on planting times in sole crop and intercropping system. Hortic. Bras. [online]. 2007, vol.25, n.4, pp. 577-581. ISSN 0102-0536.  http://dx.doi.org/10.1590/S0102-05362007000400016.

The yield of sugar beet and rocket was evaluated, as a result of planting times in sole crop and intercropping system. The experiment was carried out in Mossoró, from January to March,f 2005. The experimental design was of randomized complete blocks with nine treatments and four replications. The treatments consisted of the intercrops of sugar beet with rocket established at 0, 7, 14 and 21 days after sugar beet sowing date, as well as of sugar beet and rocket cultivated as sole crops, planted at the same times of the intercropping establishment. The highest values of fresh shoot (50.19 g/plant), dry mass (5.86 g/plant) and yield (1338.47 g/m²) of rocket were observed in the intercropping systems established at the same time. The highest values of shoot fresh mass and root yield of sugar beet were observed in sole crop. The highest land equivalent ratios were obtained in the intercropping systems where the rocket was sown at the same time of sugar beet and 7 days after sugar beet crop.
