RESUMO:

 

Brazil, despite being the world's largest producer of passion fruit (P. edulis), with 602,651 tons in an area of 43,248 ha-1, has an average productivity considered low, around 14.1 t ha-1. This low productivity is mainly attributed to climatic factors, diseases and cultural treatments. Thus, it is important that new technologies are incorporated into this culture, which represents an excellent source of income for producers, especially in the family farming segment. Thus, the objective of this work was to evaluate the growth and development of passion fruit in different cultivation environments. The experiment was carried out in the experimental area of the State University of Mato Grosso - UNEMAT. The experimental design was in randomized blocks, in a 2 x 2 factorial scheme (cultivars x growing environment) with four replications and five plants per plot. The experiment was conducted using two cultivation environments. Environment 1 was implemented in an open field and environment 2 in an arc-type agricultural greenhouse, 7 m wide by 20 m long, with sides 3.5 m above ground level and a central arch of 5 m. The polyethylene used in the roof has a thickness of 120 microns and the sides with a thermo-reflective screen 50%. The protected environment will be predominantly oriented in a geographic north-south direction. Environment 2 will be in the field, with the plant conduction system in the form of a vertical espalier, 2.5 m posts, with a spacing of 6.0 m with a number 12 smooth wire strand from 2.0 m from the ground. Fortnightly evaluations of plant height (AP), stem diameter (DC), number of leaves (NF) and number of days to prune the main stem (NDHP) were carried out, which were the number of days spent for the main stem of the plant to reach a height of 2.00 m, when the blunting was performed to break the apical dominance. Height measurements were taken with a measuring tape, taking the soil surface to its apex as a reference. Stem diameter was measured with a caliper at a height of 5 cm from the ground. For the absolute growth rate of plant height (TACAP) and stem diameter (TACDC) and percentage increment (PI), there was a significant effect for the environments and only TACAP and TACDC showed differences in cultivars, and there was no interaction between the treatments for the environment and cultivars. The highest growth rates occurred in the use of environment 1 (agricultural greenhouse) and cultivar 2 (FB300). Thus, the use of an agricultural greenhouse can improve initial growth and passion fruit performance.
