Προσθήκη ετικέτας | Περίληψη: | 7 SUMMARY This research was conducted in the community of Canchaguano province of Carchi Montufar Canton, St. Joseph parish is located in the following coordinates 00 ° 36 '36 "north latitude and 77 ° 50" 24" west longitude at an altitude 2,980 meters. Climatic and meteorological characteristics are temperature 12.5 ° C, 70% relative humidity, precipitation 1,450 mm. And the variety Quantum Semiverde used, from the same study area. Inductive-deductive, empirical analysis and synthesis called experimental: the theoretical methods were used. Treatments carried out in the research project were 10, which resulted from the combination of Factor A and Factor B. Randomized Complete Design (DBCA) blocks was used, combined factorial arrangement (AXB) with treatments included specific they giving a total of 10 treatments and three replications, a total of 30 experimental units and averages obtained in the variables were subjected to Duncan Tes 5% probability. The study objectives were to evaluate the agronomic performance of pea crop against the application of biological and chemical fungicides in controlling downy mildew, determine the efficacy of biological fungicide in controlling downy mildew, determine the effectiveness of chemical fungicides control downy mildew and perform economic analysis of treatments. The following variables were determined; incidence de la disease, severity of disease, efficiency of fungicides, plant height, stem diameter, days to flowering, number of pods per plant, yield per experimental unit and economic analysis, recording the variety Quantum with greater height plant, number of pods and yield per experimental unit in the control methods was obtained that biological control (Trichoderma), recorded significant averages recorded the lowest incidence and severity of the disease, had the highest efficiency, better production and yield per unit experimental. The treatments of the two varieties subject to biological control (Trichoderma) showed the best performance enabled a better agronomic performance of crop yield and economic utility. |
