Resumo
The objective of this study was to evaluate the effect of chicken manure associated
with superphosphate fertilizer in the production of papaya cv THB. The experiment
was conducted in a nursery farm in Linhares-ES, in a randomized block design,
factorial scheme with additional control, with four replications, with trays distributed in
tubes with a capacity of 50 cm3
containing substrado Bioplant ®. The factors were
chicken manure and superphosphate levels: five levels of chicken manure (0, 10, 20,
30, 40% v / vt) x five levels of superphosphate (0, 5, 10, 15, 20 Kg m-3) with an
additional control, the standard mixture used in the region with the fertilizer Basacote
® at a dose of 10 kg m-3. Was evaluated the percentage of emergence (PE), the
emergence speed index (ESI), the mean emergence time (MET), the rate of
chlorophyll content, height of seedlings, stem diameter, leaf number, root length, dry
mass of roots and shoots. It was found that alternative treatments have improved
only the ESI did not affect EP, and for the other variables are presented below the
standard. Thus, it is not recommended the use of chicken manure in the production
of seedlings of papaya cv. THB. Also not recommended the addition of
superphosphate to the standard substrate.
