| description | The effect of N, P and NP upon grain and stalk production of nonnodulated soybeans cv. Halesoy 71, was evaluated. Test were carried out during the 1974-1975 season in the Experimental Field of the College of Agrarian Sciences in Rosario, located in Zavalla, Santa Fe. The soil (in this locality) is a Brunizem, class II according to its utilization capacity. The experimental design consisted of randomized blocks with four replication. The P was applied in furrows in the form of Tribasic Calcium Phosphate at sowing time, while N (urea) was placed at the plant base at the time of flower sprouting. The response of non-nodulated soybeans to N application was lineal for grain production, showing a 21% increase at the highest rate utilised (125 kg/N/ha). This increment was significant with respect to the non-nodulated control plant. The production of unfertilized nodulate soybeans was 33% greated than that of the control plants, which was considered to be highly significant. Increased P rate reduced grain production as low as 10,5% for the 100 kg/P/ha rate. The control treatment could only be exceeded in 4% with 150 kg/P/ha, with was the highest rate tried. These difference were not significant All N and P combination increased grain production. The maximum dose of 100 kg of N and 100 kgof P brought about an increment of 18% which was a statistically significant difference. Stalk yield was lower in the fertilizer plots, regardless of the fertilizer used and of the dosis applied. The relation stalk weight/grain weight, decreased with higher fertilizer doses and its was due, in the case of the fertilization with N and NP, to decrease in stalk production and increment in grain yield, and for P, to a higher decrease in the production of stalk than that of grain. |

El ensayo se realizó durante la campaña 1974/75 en el Campo Experimental de la Facultad de Ciencias Agrarias de Rosario ubicado en Zavalie (Sta. Fe). El suelo es un Brunizem, clase II por su aptitud de uso. Se estudió el efecto del N, P y NP sobre la producción de granos y tallos expresados en kg/ha, en un diseño de bloques al azar con cuatro repeticiones. La aplicación del P (superfosfatc, triple de calcio) se hizo en surcos al momento de siembra y la del N (urea) a la base de la planta en el momento de la formación de los botones florales. La respuesta al N de soja no nodulada fue lineal para producción de granos, con un incremento del 21 % para la dosis máxima utilizada de 125 kg/N,/ha. Dicho incremento resultó significativo respecto al testigo no nodulado sin fertilizar. El tratamiento soja nodulada sin fertilizar rindió un 33 % más que el testigo, diferencia altamente significativa. Para P, a medida que aumentó la dosis de fertilizante, disminuyó la producción de granos respecto al testigo hasta un 10,5 % para la dosis de 100 kg/P/ha. Sólo con la dosis máxima ensayada, 150 kg/P/ha, la producción de granos superó en un 4 % al testigo. Dichas diferencias no fueron significativas. Todas las combinaciones de N y P aumentaron la producción de granos. La dosis máxima de 100 kg de N y 100 kg de P provocó un incremento del 18 %, diferencia estadísticamente significativa. La producción de tallos fue menor en las parcelas fertilizadas, independientemente del fertilizante utilizado y dosis aplicadas. La relación peso de tallos/peso de granos fue decreciente con el aumento de la dosis de fertilizante y se debió en el caso de la fertilización con N y NP, a una disminución, de la producción de tallos y a un aumento de la producción de granos, y para P, a una disminución mayor de la producción de tallos que de granos. Se interpretan los resultados obtenidos.
