Effect of planting density on yield of Solanum tuberosum in Cuemal, Lamud, Chachapoyas, Peru, using basic seed 1 and Yungay variety

Abstract

This work was carried out with the objective of evaluating the effect of different planting densities (0.40 x 0.80, 0.50 x 0.80, and 0.60 x 0.80 meters) on seed production of basic potato 1 of the Yungay variety. For this study, three planting densities of 0.40 x 0.80 m, 0.50 x 0.80 m and 0.60 x 0.80 m were used, which were compared with a control planting density of 0.30 x 0.80 m. The duration of the research was 5 months. The study was conducted in the annex of Cuemal, Chachapoyas, Amazonas Region, between October 2022 and March 2023. The design used in this research work was the Completely Randomized Block Design (CRBD), which was divided into 3 blocks, with a total area of 224 m2 and an experimental area of 196 m2. The observations recorded for data collection were: weight, size and number of tubers per plant, which was done at harvest. Finally, an analysis of variance (ANOVA) was carried out with the Tukey test at 5% significance for the multiple comparison of means; in this sense, the T3 treatment obtained the best average weight/plant of 1804.92 g, likewise the T3 treatment obtained the best size in the extra and first categories with averages of 9.00 cm and 4.80 cm respectively. In the number of tubers per plant, T3 had the best result with 14.08 tubers/plant, followed by T2 with 13.56 tubers/plant. It is concluded that the T3 treatment with a planting density of 0.60 x 0.80 m presents better results in average weight/plant of 1804.92 g, where the best estimation per hectare of 51545.25 kg of potato/ha was also obtained.
