description | 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 replication per treatment. The effect of Ne additions was valuated on grain, stalk pod yield and on protein, lipid and ash content in grains. At Power bud apperance, 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 (greatet conversion). Stalk and pod production was increased with N, being 13%a 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 he 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 conc'uded that the soybeans crop can be increased by late nitrogenous fertilization. |

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 W. RACCA r M. L. Bonrumo, Influencia de la fertilización en soja 15 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 do N, superando al testigo en un 131,1 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. De los resultados obtenidos se infiere que es posible un aumento de producción con fertilizaciones tardías de nitrógeno en cultivos de soja.
