| Summary: | <abstract language="eng">In the present work were studied several varieties of manihot of the Ubatuba area on the north coast of the State of São Paulo. The experiments were carried out at the Experiment Station of that locality with a view to compare the production of roots and meal of each variety with that of the variety "Vassourinha", introduced in that district in 1938 by the Division of Roots and Tubers of the Instituto Agronômico. Said variety ("Vassourinha") is the most cultivated all over the State of São Paulo. Results have shown that among the eleven varieties studied the following exceeded the others as regards production of roots and meal: N.° 1 ("Vassourinha") and N.° 120 ("Santa"). Comparing these two one with another, it was found that N.° 1 surpassed N.° 120, not only with regard to production of roots but also in regard to manufacture of meal. Through the study of production of cuttings it was found that in no variety whatever there is a relationship between the production of stems and roots. Finally, analyses are mentioned of meal obtained from each variety both of one and two vegetative cycles. |
