Resumo


Physalis peruviana L. (Solanaceae) is an Andean shrub species that produces sugary fruits.
The cultivation of this species is recent, thus, aspects related to soil fertilization for it still need to be
studied. The objective of this work was to define the rates of NPK fertilizer applied at planting that
meet the requirements of physalis crops. The experiment was conducted at Institute Federal of Minas
Gerais (IFMG), Campus Bambuí, from February 25 to November 23, 2015. A completely randomized
design was used, with 8 treatments and 6 replications, totaling 48 experimental units. The treatments
consisted of N, P2O5, and K2O rates (kg ha-1), using urea (45% N), monoammonium phosphate
(9% N and 44% P2O5), and potassium chloride (58% of K2O). Morphological and bromatological
characteristics and fruit production were evaluated. Data were subjected to analysis of variance and
the means grouped by the Scott-Knott test at 5% probability. The NPK rate that generates the higher
fruit production and greater savings is 1200 mg dm-3 of N, 3600 mg dm-3 of P2O5, and 2400 mg
dm-3 of K2O, and the NPK rate that results in greater morphological development is 1600 mg dm-3 of
N, 4800 mg dm-3 of P2O5, and 3200 mg dm-3 of K2O.
