Potato Plant Research

This research was carried out in the district of Luya, province of Chachapoyas, Amazonas, with the objective of evaluating the optimal dose of gibberellic acid (Full Gib) in the induction of sprouting of potato tubers (Solanum tuberosum L.) Yungay variety. A Completely Randomized Design (CRD) with two factors three replications and seven treatments was used. Minitat 17 statistical software, ANOVA, and the Tukey mean comparison test at 5% were used for data analysis. The treatments were: Nothing was applied (T1), 7.5 mL of Full Gib in 20 L of water, for 15 min (T2), 7.5 mL of Full Gib in 20 L of water, for 20 min (T3), 10 mL of full Gib in 20 L of water, for 15 min (T4), 10 mL of full Gib in 20 L of water, for 20 min (T5), 12. 5 mL of full Gib in 20 L of water, for 15 min (T6), 12.5 mL of full Gib in 20 L of water, for 20 min (T7). The variables evaluated were: Sprouting percentage, number of sprouts, sprout length, and sprout diameter per tuber. According to the results obtained, it can be observed that treatments 5 and 3 obtained the highest germination percentages with 86.17 and 85.67%, respectively, surpassing the other treatments; there were no significant differences between treatments in the number of sprouts per tuber. Treatments 5, 3, and 4 were better, with results of 8.93, 8.83, and 8.68, respectively; on the other hand, the variable shoot length obtained the best results in treatments 5 and 3 with 7.69 and 7.50 cm, respectively. Similarly, the shoot diameter variable had positive results in treatments 3 and 5 with 6.0 and 5.9 mm, respectively.
