Correspondence: [email protected]; [email protected] objective was to evaluate the effect of inoculation with Azospirillum brasilense
and levels of nitrogen fertilization on the productive aspects of the spineless cactus (Nopalea
cochenillifera). The experiment was carried in Ribeirão do Largo, Southwest region of the state
of Bahia, from April 2019 to April 2020. The experiment was carried out in a 2×4 factorial, in a
randomized block design with eight treatments and four replications. The treatments consisted of
the absence or inoculation with Azospirillum brasilense and nitrogen fertilization levels 0, 50,
100 and 150 kg–
¹ of N ha–¹
. There was a positive effect for the use of the bacteria on cladode area
index, height, number of secondary, tertiary and total cladodes, total weight for cladodes of all
orders and also for final weight per ha–¹
. There was a significant effect of the use of the inoculant
for the levels of total soluble sugars and starch, where there was a decrease in the values for the
treatments submitted to the use of the bacteria. There was a quadratic effect for the weight of the
tertiary cladodes, number of tertiary cladodes and total of spineless cactus when submitted to
nitrogen fertilization levels. There was a linear test for cladodes area index when nitrogen
fertilization was used. The use of Azospirillum brasilense is positive for the cultivation of
spineless cactus, improving development and increasing crop productivity
