Comportamiento agronómico de las variedades de maní “INIAP 382” e “INIAP 383”, con cuatro densidades de siembra en la zona de Babahoyo

VIII. SUMMARY This research was conducted in the fields of experimental farm "San Pablo" of the Faculty of Agricultural Sciences at the Technical University of Babahoyo, located at Km. 7.5 of Babahoyo Montalvo route. The area has a humid tropical climate, with a height of 8 m.s.n.m .; located between 79º 32' geographic coordinates, longitude west and south latitude 49' 1, with an average rainfall of 162.8 mm, with an average annual temperature of 24.32 ° C. It was used as seed material peanut varieties from the National Institute for Agricultural Research, INIAP-382 and INIAP-383, whose objectives were to identify the most appropriate density for each cultivar and economically analyze seed treatments. eight treatments, on two factors, which were Factor A peanut varieties INIAP-382 and INIAP-383 and Factor B planting densities were studied 81632; 71428; 62500 and 49382 plants / ha, whose planting distances were 35 x 35; 35 x 40; 40 x 40; 45 x 45 cm. The experimental design used was the randomized complete block in factorial arrangement A x B, with 3 replications. Comparisons of treatment means were performed by multiple Duncan test at 5% probability. During assay development the work of soil testing, land preparation, seed disinfection, planting, thinning, fertilization, weed control, pest and disease control, irrigation and harvesting were conducted. To determine the effects of treatment variables days to flowering and harvest were evaluated; plant height at harvest; number of pods per plant grains and branches; seeds per pod; vaneamiento percentage; weight of 100 seeds; yield kg / ha and economic analysis. The results found that peanut varieties "INIAP-382" and "INIAP-383", studied with four planting densities, good agronomic performance achieved in the area of Babahoyo; planting peanut variety INIAP-382 with density of 49382 plants / ha was the treatment that took to blossom and harvested; the tallest plants to harvest the reported variety INIAP-383 with 81632 plants / ha density planting; the highest number of pods / plant and seeds / pod dominated the variety INIAP-382 with 62500 plant / ha; INIAP-383 variety with planting density of 81632 plants / ha obtained greater number of grains / plant; INIAP-382 with density of 81632 plants / ha showed a higher number of branches / plant; the highest percentage of vaneamiento was observed in the INIAP-382 variety with peanut planting density of 49382 plants / ha; the greater weight of 100 seeds and grain yield reached the peanut variety INIAP-383 with 62500 plants / ha with 67.4 g 3798.7 kg / ha and planting INIAP-308 with density of 62500 plants // ha higher net profit reached with $ 3591.29
