Effect of nitrogen fertilization on nodulated soybeans (CV. Halesoy 71)

A nitrogenous fertilization trial with nodulated soybeans cv. Halesoy 71, was carried out on a Brunizem class II soil, according to its use capacity, in the locality of Fuentes, Santa Fe Province, during 1975-1976 season. Experiments were conducted in a completely randomized design with six replicat...

L. fertilización nitrógeno en soja nodulada CV.Halesoy 71 fertilization nitrogen in nodulated soybeans CV.Halesoy 71 A nitrogenous fertilization trial with nodulated soybeans cv. Halesoy 71, was carried out on a Brunizem class II soil, according to its use capacity, in the locality of Fuentes, Santa Fe Province, during 1975-1976 season. Experiments were conducted in a completely randomized design with six replications per treatment. The effect of N additions was valuated on grain, stalk and pod yield and on protein, lipid and ash content in grains. At flower bud appearance, the nitrogenous fertilizer (urea) was applied at the plant base. A lineal response to N, expressed as grain yield, was obtained with nodulated soybean; the highest dose used (200 kgs/N/ha) resulted in 15% grain increase. However, 100 kgs/N/ha was the most effective dose (greater conversion). Stalk and pod production was increased with N, being 13,1% higher than that of the control at the maximum N level employed. The ratio stalk weight plus pods/grain weight was lower in fertilized than in non fertilized plots, mainly because of greater grain production. No correlation was observed between “vaneo”-yield and “vaneo”-total N whereas grain yield was found to be highly correlated with the total number of pods per plant. Grain protein content was greater with increased amounts of fertilizer, the reverse occurring with lipid content. Ash amount was practically constant. According to the results obtained, it is concluded that soybean crop can be increased by late nitrogenous fertilization. El presente ensayo de fertilización nitrogenada en soja nodulada cv. Halesoy 71 fue realizado durante la campaña 1975/76 en un suelo Brunizem clase II por su aptitud de uso, en Fuentes (Prov. de Santa Fe). Se condujo en parcelas totalmente aleatorizadas con 6 repeticiones por tratamiento. Se estudió el efecto del N agregado sobre la producción de granos, tallos y vainas, y el contenido de proteínas, materia grasa y cenizas en granos. El fertilizante nitrogenado (Urea) se aplicó a la base de la planta, en el momento de aparición de los botones florales. La respuesta al N de la soja nodulada fue lineal para producción de granos, con un incremento del 15% para la dosis máxima utilizada de 200 kg/N/ha; la dosis más eficiente no obstante, fue la de 100 kg/N/ha (mayor conversión). La producción de tallos y vainas se incrementó con el aumento de la dosis de N, superando al testigo en un 13,1% para la dosis máxima de N utilizado. La relación peso de tallos más vainas/peso de granos fue menor en las parcelas fertilizadas, debido fundamentalmente, a un aumento de la producción de granos. Existió independencia entre las variables “vaneo”-rendimiento y “vaneo”-nitrógeno total, mientras que estuvo correlacionado el rendimiento en granos con el número total de frutos de planta. El contenido de proteínas en granos aumentó con el aumento de la dosis de fertilizantes, ocurriendo lo contrario con el contenido de materia grasa. El de cenizas se mantuvo prácticamente constante.  Facultad de Ciencias Agropecuarias 1981-06-01 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion application/pdf https://revistas.unc.edu.ar/index.php/agris/article/view/888 10.31047/1668.298x.v2.n1.888 AgriScientia; Vol. 2 (1981); 7-16 AgriScientia; Vol. 2 (1981); 7-16 1668-298X 10.31047/1668.298x.v2.n1 spa https://revistas.unc.edu.ar/index.php/agris/article/view/888/823 Derechos de autor 1981 Walter Racca, M.L Brodero https://creativecommons.org/licenses/by-sa/4.0
