Item Adaptabilidad de trece cultivares de brócoli (Brassica oleracea var. Itálica L.) En el cantón Pujilí, provincia de Cotopaxi.(2022-11) Cuji Bunsi, Yomara Esthela; Veloz Naranjo, Walter OswaldoIn the present study, the adaptability of broccoli cultivars (Brassica oleracea var. Itálica L.) was evaluated: Avenger, EMBR940, MKS-B106, EMBR958, MKS-B116, EMBR924, MKS-B111, Roxanne, Haiyan, EMBR266, EMBR944, EMBR258 and Kin 257, where the percentage of capture was established where the cultivar EMBR924 was the one that obtained a better range of capture and the cultivar Kin 257 obtained the lowest range of capture, in terms of plant height at 30 days the best range was obtained by cultivar EMBR924 with an average of 21.50 cm, while for the height of the plant on the days of harvest it was the cultivar Avenger with an average of 75.41 cm, for the variable days to harvest after transplantation, the cultivar EMBR958 was the one that presented a shorter cycle with an average of 82 days. For the equatorial diameter and the weight of the pellet, the most representative cultivar was Avenger with an average of 942.80 grams, followed by the cultivar EMBR940 with an average of 658.67 grams, being an ideal weight for marketing, for the other variables. As for compactness, shape and color, the cultivars Avenger, EMBR940 and EMBR258 presented the best characteristics such as the well-formed and compact dome, in addition a bluish green color was observed. With these classification variables, it was possible to define the cultivar with the best response to be cultivated in the Molino Pata neighborhood sector located in the Pujilí canton, in the province of Cotopaxi, which in this case were the Avenger cultivars with a yield rate of 27.32 Tn/ha and the EMBR940 cultivar presenting balanced characteristics in the physical aspect of its pellet, in addition to a yield rate of 18.82 Tn/ha.Item Evaluación de diferentes proporciones de sustratos en el crecimiento de plántulas de uvilla (Physalis peruviana)(2022-09) Toscano Mañay, Jessica Alexandra; Dobronski Arcos, Jorge EnriqueSubstrates are of great importance to achieve a good development of seedlings, because they allow them to develop a good root system in order to obtain a better quality. The cape gooseberry (Physalis peruviana) is a fruit species from the Andean territory that is considered a wild fruit, since its seeds are more easily propagated. In the present work, the effect of different proportions of substrate on the development of cape gooseberry seedlings was evaluated in order to determine the treatment that would allow obtaining better quality plants with desirable characteristics. Six treatments were evaluated: T1 (agricultural dream 100%), T2 (agricultural soil 50% + guinea pig manure 50%), T3 (agricultural soil 40% + sawdust 20% + rock flour 40%), T4 (sand 50% + rock flour 30% + sawdust 20%), T5 (agricultural soil 70% + sawdust 30%) and T6 (agriculturalsoil 70% + rock flour 30%). A completely randomized block experimental design with three replications was used. The variables evaluated were plant height, number of leaves, stem diameter, root length and percentage of useful plants. Data were collected 30, 40, 60 and 80 days after planting. The best treatments were T1 (agricultural soil 100%) and T6 (agricultural soil 70% + rock flour 30%). The variable number of leaves, an average of 3.53 was recorded at 30 days and 5.17 at 80 days, with a difference of 1.64 leaves. Plant height was 1.03 cm at 30 days and 4.53 at 80 days. The stem diameter variable showed a difference of 0.09 cm from day 40 to day 80. For root length, mean values were 7.99 cm at 40 days and 15.58 cm at 80 days, with a difference of 7.59 cm. The percentage of useful plants was 53% with treatment T1. It is concluded that there is an influence of the different proportions of substrates on the growth and development of seedlings.
