The Jatropha curcas L. is a shrub of the family Euphorbiaceae widely cultivated in tropical countries. Current study analyzes the effects of the manioc milky juice, known as manipueira in Brazil, and cow urine on the growth of jatropha. The experiment was conducted between January and December 2010 at CCAA, Campus II of UEPB, in Lagoa Seca PB Brazil. The assay had a 5 x 5 factorial design and randomized blocks with 25 treatments and 4 replications per treatment, divided into 4 blocks, with different volumes of cow urine and manipueira broth. The application of 1000 ml of the biofertilizer with cow urine increased the stem diameter by 4.75 %, number of leaves by 18.70 % and foliar area by 837.67 % when compared to control. Further, 1000 ml of manipueira broth increased the number of leaves and the foliar area of the jatropha plant by 53.48 % and 414.02 %, respectively when compared to the lowest rate. The interaction of cow urine and 1000 ml of manipueira broth increased the stem diameter by 23.53% when compared to the lowest rate and by 543.01 % of the foliar area. Results show that different volumes of biofertilizers with cow urine and manipueira affected the growth of jatropha plants during 360 days, except for the variable plant height.
