Growth, accumulation and distribution of dry matter in two varieties of amaranth (Amaranthus hypochondriacus L. y A. cruentus L.) under fertigation
Amaranth crop is adapted to arid and semi-arid agroclimatic conditions. Its grain yield can be increased with fertigation, but there is limited information on growth parameters and crop yield under this system.

Its grain yield can be increased with fertigation, but there is limited information on growth parameters and crop yield under this system. The objective was to characterize growth, accumulation and distribution of biomass of two varieties of amaranth (Frondosa and Dorada) under fertigation. The experimental phase was carried out at Salinas, San Luís Potosí, at a density of 25 plants per m2. Organomineral fertilization was applied to soil, and chemical fertilization through irrigation, whose total water sheet was 321 mm. Frondosa compares to Dorada, reached faster maturity and presented higher values of: leaves number; panicle length and dry biomass; and harvest index (gain/total dry biomaas). Thermal requirement was 910.7 °C and 968.6 ºC for Frondosa and Dorada, respectively. Frondosa had higher water use efficiency (WUE) (7.1 kg mm-1) in grain production (2.3 t ha-1), but WUE for fresh biomass (69.6 t ha-1) was higher in Dorada (194.7 kg mm-1). Environmental conditions in Altiplano Potosino are favorable to produce amaranth with high yield (grain or forage) under fertigation. El cultivo de amaranto se adapta a condiciones agroclimáticas de regiones áridas y semiáridas. Su rendimiento de grano puede incrementarse con fertirriego, pero es necesario generar más información sobre parámetros de crecimiento y rendimiento del cultivo bajo este sistema. El objetivo fue caracterizar el crecimiento, acumulación y distribución de materia seca de dos variedades de amaranto (Frondosa y Dorada) bajo fertigación. La fase de campo se realizó en Salinas, San Luis Potosí, con una densidad de 25 plantas por m2. Se aplicó fertilizante organomineral al suelo y nutrición química en el agua de riego, cuya lámina total fue 321 mm. Frondosa, respecto a la Dorada, llegó más rápido a madurez y mostró valores mayores en: número de hojas; longitud y biomasa seca de panoja; e índice de cosecha (grano/biomasa total). El requerimiento térmico total fue de 910.7 °C y 968.6 ºC para Frondosa y Dorada, respectivamente. Frondosa tuvo mayor eficiencia en el uso del agua (EUA) (7.1 kg mm-1) en grano (2.3 t ha-1), pero la EUA para biomasa fresca (69.6 t ha-1) fue mayor en Dorada (216.6 kg mm-1). Las condiciones ambientales del Altiplano Potosino son favorables para producir Amaranto con alto rendimiento de grano o forraje con fertigación.

Amaranth crop is adapted to arid and semi-arid agroclimatic conditions. Its grain yield can be increased with fertigation, but there is limited information on growth parameters and crop yield under this system. The objective was to characterize growth, accumulation and distribution of biomass of two varieties of amaranth (Frondosa and Dorada) under fertigation. The experimental phase was carried out at Salinas, San Luís Potosí, at a density of 25 plants per m2. Organomineral fertilization was applied to soil, and chemical fertilization through irrigation, whose total water sheet was 321 mm. Frondosa compares to Dorada, reached faster maturity and presented higher values of: leaves number; panicle length and dry biomass; and harvest index (gain/total dry biomaas). Thermal requirement was 910.7 °C and 968.6 ºC for Frondosa and Dorada, respectively. Frondosa had higher water use efficiency (WUE) (7.1 kg mm-1) in grain production (2.3 t ha-1), but WUE for fresh biomass (69.6 t ha-1) was higher in Dorada (194.7 kg mm-1). Environmental conditions in Altiplano Potosino are favorable to produce amaranth with high yield (grain or forage) under fertigation. |
