The work was conducted in greenhouse and aimed to analyze the growth and partitioning of assimilates in Physalis peruviana subjected in intervals of leaf fertilization. The plants were collected at regular intervals of fourteen days after transplantation until the end of the cycle and determined the dry mass and leaf area. From the primary data analysis was applied to growth analysis and calculated the total dry matter production (Wt), rates of dry matter production (Ct), relative growth (Rw), net assimilation (Ea), leaf area index (L), relative growth of leaf area (Fa) and ratios of leaf area and leaf mass (Fw), specific leaf area (Sa) and dry matter partitioning between organs. Plants of Physalis peruviana subjected to leaf fertilization biweekly reached higher Wt, Ct, number of fruits and similar dry mass of fruits (Wfr) of plants subjected to foliar weekly application and higher Wfr compared to plants without application leaf of fertilization. Thus, the application of leaf fertilization provided benefits of growth and the partition of assimilates in Physalis peruviana plants.
