Adaptation of blueberry crop (Vaccinium corymbosum) under macro-tunnel in Valle de Santiago, Gto.

In order to evaluate the adaptation of Ventura variety blueberry (Vaccinium corymbosum) cultivation under macro tunnel, an experiment was established at the Southwest Technological University of Guanajuato from January to April 2022. The study was established based on a completely randomized experimental design with five treatments and four repetitions. The treatments to be evaluated were four foliar fertilizers: Citan® (rooting hormones); formula 20-30-10 (N, P, K + Microelements); Bayfolan Forte® (N, P, K + Microelements); Demeter Poto® (K, B, Zn, P), applied weekly and an absolute control. The number of green sprouts developed three months after the first application was evaluated. The statistical analysis showed that there were no significant differences (p = 0.01) between the foliar fertilization treatments; however, an average of 13 to 16 green sprouts was counted, all with good development, vigor and physical appearance; largely due to foliar fertilization as a complement to nutrition via irrigation. The adaptation of the blueberry crop was achieved, as a recently introduced species in Valle de Santiago, under macro tunnel conditions, the microclimate and implemented agronomic management; however, it is necessary to improve some management aspects such as nutrition and above all, provide optimal protected conditions for cultivation.
