PIRES, Regina Célia de Matos et al. Vegetative growth and yield of strawberry under irrigation and soil mulches for different cultivation environments. Sci. agric. (Piracicaba, Braz.) [online]. 2006, vol.63, n.5, pp. 417-425. ISSN 1678-992X. http://dx.doi.org/10.1590/S0103-90162006000500001.
The vegetative growth and yield of strawberry in relation to irrigation levels and soil mulches are still not well known, mainly for different environmental conditions. Two experiments were carried out in Atibaia, SP, Brazil, during 1995, one in a protected environment and the other in an open field, to evaluate the cultivar Campinas IAC-2712, under different irrigation levels and soil mulches (black and clear polyethylene). Three water potential levels in the soil were used in order to define irrigation time, corresponding to -0.010 (N1), -0.035 (N2), and -0.070 (N3) MPa, measured through tensiometers installed at the 10 cm depth. A 2 × 3 factorial arrangement was adopted, as randomized complete block, with 5 replicates. In the protected cultivation, the irrigation levels of -0.010 and -0.035 MPa and the clear plastic mulch favored the vegetative growth, evaluated through plant height, maximum horizontal dimension of the plant, leaf area index, as well as by total marketable fruit yield and its components (mean number and weight of fruits per plant). In the open field cultivation, no effect of treatments due to rainfall were observed.
