Abstract:
In this context, the objective was to study combinations of nitrogen and phosphorus
in proportions and the volume of container in the production of moringa seedlings, a
test was conducted in a protected environment (greenhouse), using the randomized
block design, with a factorial scheme of 10 x 3, referring to 10 combinations of
fertilizer: : T1 = 0% (control); T2 = N150% and P150%; T3 = N150 and P100%; T4 =
N100 and 150%; T5 = N150 and P50%; T6 = N50 and P150%; T7 = N100 and
P100%; T8 = N50 and P50%; T9 = N50 and P100P; T10 = N50 and P50% and three
volumes of container (1, 2 e 3 dm3), with 4 blocks and two plants per plot, totaling
240 plots. The application of the treatments (via irrigation water) occurred one day
before sowing, with the remaining applications every 15 days after emergence.
During the conduction of the experiment the moringa seedlings were evaluated for
growth, done every twenty days and evaluation of gas exchange at 60 days after
sowing DAS. It was verified that fertilization with the proportions of 50% N and 50%
of P responded well in the container of volume 3 dm3 providing better growth in
diameter of the neck and height, as well as in the physiological characteristics in
moringa seedlings.
