| description | Proceeding previous work for the adjustment of Chaminade's substractive method to soils of the central region of Córdoba, in 1972, a factorial experiment was conducted, three concentration level of the solutions for initial complete fertilization ( N, P, K, Ca, Mg, S, and minor elements) and five levels of weekly addition of N (NH4NO3 solution ) were utilized. The experience was conducted with six samples corresponding to two soil profiles: one a zonal soil of the Manfredi Agr. Exp. Station (INTA) with a texture corresponding a silt loam and the other an alluvial soil on terraces of the Río Tercero river, being a coarse sandy loam and representative of an area of peanut monoculture. Bye grass ( Loliuin multiflorunt L.) as utilized as test plant, valuating dry matter production by cuttings at two week intervals. Etch treatment was carried on with two replications, rotating the pots in each of them every time water or nitrogen solution was added. The analysis of the accumulated dry matter production of succesive cuttings permits to establish as optimum concentrations , or nearly so, the following: 0,5 times the concentration of the initial complete fertilization solutions and 0,25 times the concentration of the weekly supply of N as NH 4NO3 solution, both values in relation to those indicated in the original method. |

Prosiguiendo trabajos anteriores para adaptar la técnica sustractiva de Cilaminade a suelos de la región central de Córdoba se realizó, en 1972, un ensayo factorial utilizando tres niveles de concentración de las soluciones de fertilización completa inicial (N, P, K, Ca, Mg, S y Em) y cinco niveles de aporte semanal de N (solución de NH4NO3). El ensayo se realizó con seis muestras de suelo correspondientes a dos perfiles: uno de ellos correspondiente a un suelo zonal ubicado en la EEA Manfredii INTA, de textura franco-limosa, y el otro de un suelo aluvial próximo a la localidad de Villa Ascasubi, cercano a la margen izquierda del Río Tercero, de textura franco arenosa y representativo de áreas donde predomina el monocultivo de maní. Se utilizó "raigra4" (Loliurn ntultiflorvrm L.) como planta índice, evaluando la producción de materia seca mediante cortes bi-semanales. Cada tratamiento se condujo con 4 repeticiones, rotando dentro de cada una de ellas los recipientes en ocasión de cada riego y/o aplicación semanal de las soluciones aportantes de N. El análisis de las producciones acumuladas de los sucesivos cortes permite establecer como concentraciones óptimas, o lo suficientemente aproximadas, las siguientes: para ambos suelos: 0,5 de la concentración de las soluciones de fertilización completa inicial y 0,25 de la solución de NH4NO3 de aporte semanal de N, ambos valores con relación a lo estipulado en el método original.
