Abstract

The Cowpea aphid borne mosaic virus (CABMV), which causes the disease known as hardening of passion fruit, has caused extremely significant losses to State of São Paulo production, reducing cultivated area by 48,6% in the main producing regions in the last five years. Faced with the slowness of conventional breeding programs to obtain resistance, plus the current system of production of seedlings that favors infection, management options were adopted for coexistence with the virus. The use of advanced seedlings produced in a protected environment associated with the annual crop reduces the period of exposure of the plant to the action of the virus, allowing to recover the productivity of the plants. However, this technology still lacks adequate fertilization and spacing information's to achieve the expected results. Thus, the objective of this research is to identify the adequate nitrogen dose and spacing for annual orchards installed with advanced seedlings (1.2 to 1.5 m height). The experimental design will be randomized blocks in split plots and four replications. (AU)
