Chemical and organic fertilization in oats: seed yield and quality: Español
Introduction. Oatmeal (Avena sativa L.) has its origin in Central Asia and is an important crop in Mexico, where there are high grain yields, besides as being an alternative for producers who sow in temporary. Objective. To evaluate the effect of chemical and organic fertilization on the yield and physiological quality of the seed of three oats varieties, during two agricultural cycles (years). Materials and methods. The experiment was established during the autumn-winter cycle at the Tecnologico Nacional de Mexico campus Roque, Guanajuato, Mexico. Two sowing dates were established in 2015 and 2016, considered as factor A. The varieties of the experiment were Turquoise, Diamond, and Chihuahua, assigned as factor B and five fertilizations based on vermicompost and chemical nutrition as factor C, sowed in three replications. Seed physiological quality variables and seed yield components were measured. Characteristics were analyzed in a randomized complete block design with factorial arrangement and a Tukey 0.05 mean comparison test. Results. The environmental effect influenced the seed quality, agronomic characteristics, and grain yield. In the 2016/17 cycle there was a 14.41 % increase in seed yield compared to the 2015/16 cycle. The three oats varieties maintained the same behavior pattern, statistically the same for germination, days to seedling (appearance of the flower knot on the stem), days to flowering, number of seeds per spike, weight of 1000 seeds and seed yield. Oat yield and other physiological quality characters were similar with vermicompost (6.38 t ha-1) and chemical fertilization (6.46 t ha-1). Conclusion. A similar response was found in yield, weight of 1000 seeds, and physiological seed quality, with both types of fertilization.
