| description | Inefficient fertilization practices, as well as
relatively low planting densities in garlic
crops, determine high production costs and
yields below crop potential. In order to
study the response of Mediterranean garlic
clones to combinations of planting
densities and nitrogen supply modes, three
clonal cultivars ("Unión", late white garlic,
"Gostoso INTA" and "Rubí INTA", red
garlic) were tested at the Agricultural
Experimental Station La Consulta INTA
(33.7 S, 69.7 W, 940 m.a.s.l.). Six
arrangements combining two planting
densities (28 and 56 plants.m-2
) and three
nitrogen supplying modes (without
fertilizing; 180 kg.ha-1
until bulbing
beginning; 70% of the dose until bulbing
beginning and 30% from rapid bulb
growth), were established. With 33
physiological and environmental
covariates, principal components analysis
and partial-least squares regression
analysis were performed. Doubling the
traditional plant population substantially
increased total yield of garlic, with better
response in the late white clone. The stage
of rapid vegetative growth was defined as
of main importance in determining the
response to high density in Mediterranean
clones. Nitrogen dose partitioning did not
show consistent differential responses.
Those findings provide new insights for improving crop-ecophysiology-based
management practices in garlic, in terms of
plant density and cultivar selection. |

En cultivos de ajo, prácticas de fertilización poco eficientes y el uso de densidades de plantación relativamente bajas determinan altos costos de producción y rendimientos por debajo del potencial. A fin de estudiar la respuesta de clones de ajo mediterráneos frente a combinaciones de densidades de plantación y modalidades de provisión de nitrógeno, en la Estación Experimental La Consulta INTA (33,7 S; 69,7 O; 940 m.s.n.m.) se probaron tres cultivares clonales (“Unión”, blanco tardío, y “Gostoso INTA” y “Rubí INTA”, colorados), en 6 combinaciones de dos densidades de plantación (28 y 56 plantas.m-2 ) y tres modalidades de provisión de nitrógeno (sin fertilizar; 180 kg.ha-1 hasta inicio de bulbificación; 70% de la dosis hasta inicio de bulbificación y 30% desde rápido crecimiento del bulbo). Con 33 covariables fisiológicas y ambientales se realizaron análisis de componentes principales y de regresión por mínimos cuadrados parciales. Duplicar la población de plantas tradicional permitió incrementar sustancialmente el rendimiento total, con mejor respuesta en el clon blanco tardío. Se define que la etapa de rápido crecimiento vegetativo es de principal importancia en determinar la respuesta a la alta densidad en los ajos mediterráneos. La partición de la dosis de nitrógeno no consiguió generar respuestas diferenciales consistentes. Esos hallazgos proporcionan nuevos conocimientos para mejorar las prácticas de manejo del ajo basadas en la ecofisiología de los cultivos, en términos de densidad de plantación y selección de cultivares.
