LEONEL, Sarita  e  DAMATTO JUNIOR, Erval Rafael. Root distribution of fig trees cultivated with organic manure. Rev. Bras. Frutic. [online]. 2007, vol.29, n.1, pp.191-194. ISSN 0100-2945.  http://dx.doi.org/10.1590/S0100-29452007000100041.

The research had as purpose to evaluate the root system distribution of 'Purple of Valinhos' fig plants cultivated with manure levels, during four years. The fig orchard was planted in Botucatu-SP, at a Red Nitossolo soil with the plants designed at 3 m between lines and 2 m between plants. The treatments were constituted by increasing organic manure levels with cattle manure, according to the recommended nitrogen level for the trees: control (without manure), 25%, 50%, 75%, 100%, 125% and 150% of level manure recommended. The evaluation of root system distribution were made four years after the orchard installation. From each plant were taken four samples at 0-40 cm distance of the stem, in the depth of 0-40 cm. After, the samples were washed and dried (65 ºC) for post-evaluation of the dry weight, depth and distance of the roots. It was observed that the root development was higher in the horizontal position when compared with the vertical. The bigger root weight was obtained with the application of 150% of N level recommended and the smaller root weight was observed without manure (43,3 g).
