Item Adaptación de tres híbridos de tomate hortícola (Lycopersicum esculentum) bajo cubierta plástica(2023-09) Tubón Tite, Wendy Lizbeth; Curay Quispe, Segundo EuclidesThe research focuses on the behavior of three horticultural tomato hybrids (Lycopersicum esculentum) under plastic cover. A completely randomized block experimental design (DBCA) was used with 3 treatments and a commercial control and 4 repetitions. Several variables were evaluated, such as survival percentage, plant height, stem diameter, number of days to flowering, number of days to fruiting, number of days to harvest, number of fruits, distance between clusters, equatorial diameter. , polar diameter and fruit weight. For the statistical analysis of the data, the SPSS Statistics program was used and tests such as Scheffe were applied with a significance of 0.05; Homogeneity of variances with a confidence level of 95%. Showing that the three horticultural tomato hybrids successfully adapted under plastic cover in the Huachi Grande parish, Ambato canton, Tungurahua province. Where it was observed that the H1-Arsin Hybrid showed outstanding results in the variables studied during the investigation, as the third best in survival with 94.28%, greater stem diameter at 75 days with 1.41 cm, fewer days of flowering with 42.55 days, fewer days of fruiting with 57.70 days, greater polar diameter with 6.26 cm and higher yield (20,100 kg/ha), the shape of the fruit was round, which indicates a favorable fruit production in this variety and adapted to the environmental conditions of the Huachi Grande parish, which makes it the most promising option in the study.Item Evaluación del comportamiento agronómico de cuatro líneas promisorias de avena bajo las condiciones agroecológicas de Querochaca(2023-03) Moposita Taipe, Alexandra Magay; Dobronski Arcos, Jorge EnriqueOats (Avena sativa) is a very important crop worldwide, in Ecuador this crop has come to have a good adaptation thanks to the geographical characteristics that it presents, the present investigation had the purpose of evaluating the agroecological behavior of 4 promising lines of oats in the sector Querochaca in order to determine which variety of oats has the best agroecological adaptation in the study place, in the Querochaca sector, 4 promising lines of oats and a control were cultivated, which was designed an essay with 3 repetitions for each of the variables, The variables that were taken into account were: Days to spike, plant height, type of straw, spike size, number of grains per spike, yield, hectoliter or specific weight, weight of a thousand grains, type and color of grain, diseases. For the results, they were analyzed using tables and graphs obtained by the INFOSTAT software. The appearance of the panicle in line AS-17- 002 was 109 days for which it was determined with a late promising line. Finally, it was possible to determine that the AS-17-000 lines have a higher yield and a better adaptation to the agroecological conditions of the area.Item Evaluación del comportamiento agronómico de cuatro líneas promisorias de cebada bajo las condiciones agroecológicas del sector Querochaca(2023-03) Naranjo Freire, Diego Alejandro; Dobronski Arcos, Jorge EnriqueThe present research work evaluated the agronomic behavior of four promising lines of barley, under the agro ecological conditions of the sector of Querochaca, the promising lines and the improved variety were provided by the INIAP cereals program, a completely random block design was employed with 5 treatments with 3 repetitions, in the research we studied variables such as days of tasseling, plant height, spike size, thatch type, number of grains per spike, yield, thousand grain weight, hectolithic or specific weight, type and color of grain and diseases, for each variable was used the test of Shapiro Wilks, homogeneity, ADEVA and Tukey to 5%, already finished the investigation the promising lines have been adapted to the agro ecological conditions of the field Querochaca in Cevallos canton, province of Tungurahua. Promising lines were obtained that stood out much more than others, the promising line CD-19-004 was the line that was better adapted to agro ecological conditions, presenting 85.33 days to the stem, plant height 125 cm, an intermediate stem, a medium grain, round shape, white color and good appearance, there was presence of diseases yellow leaf rust (Puccinia striiformis) with a severity of 38.8%, leaf rust (Puccinia hordei) present a severity of 6.67% and yellow dwarfism barley virus (BYDV) present traces of yellowing of the tip of few leaves, vigorous looking plant, CD-19-004 was the best promising line compared to the remaining three lines (CD-19-013, CMU-19-002, CMU-19-001) and surpassing the improved variety INIAP-CAÑICAPA 2003.
