| description | Beetroot was grown in an open soilless cultivation system with nutrition supplied
by organic and inorganic sources. This low emission system was tested for microgardening
high quality red beets with high water use efficiency and less pollutant emission
in the environs. For this purpose, a pot experiment was planned according to completely
randomized design. For inorganically grown red beets, peat moss was combined with
150, 200 and 250 ppm NH4NO3, whereas for organic red beets, peat moss was amended
with compost having nitrogen equivalent to the mentioned NH4NO3 concentrations.
Rosette and roots were analysed for fresh and dry biomass. Nitrate content, total soluble
solids, titratable acidity, ripening index, ascorbic acid, betacyanins, flavonols and antioxidant
capacity were assessed as beetroot quality attributes. Combination of peat moss
with NH4NO3 showed comparatively lower fresh plant biomass, fresh and dry biomasses
of rosette and root, and root to rosette ratio. However, enhanced antioxidant activity and
bioaccumulation of ascorbic acid, total soluble solids, betacyanins, flavonols and reduced
titratable acids, resulting in higher ripening index and good quality were observed in
peat moss combined NH4NO3 treated beetroots. Overall, combination of peat moss with
NH4NO3 led to higher nutritional and antioxidant quality of red beet plants. |

La remolacha se cultivó en un sistema de cultivo abierto sin suelo con nutrición suministrada por fuentes orgánicas e inorgánicas. Este sistema de baja emisión fue probado para la microhorticultura de remolachas rojas de alta calidad con una eficiencia alta de uso de agua y menor emisión de contaminantes a los alrededores. Con esta finalidad se planificó un experimento en macetas de acuerdo con un diseño completamente al azar. Para las remolachas rojas cultivadas inorgánicamente se combinó musgo de turbera con 150, 200 y 250 ppm de NH4NO3, mientras que para las orgánicas se adecuó el musgo de turbera con compost con un contenido de nitrógeno equivalente a las concentraciones de NH4NO3 mencionadas. Se analizó el contenido de biomasa fresca y seca de la roseta y de la raíz. El contenido de nitratos, los sólidos solubles totales, la acidez titulable, el índice de maduración, el ácido ascórbico, las betacianinas, los flavonoles y la capacidad antioxidante se evaluaron como atributos de calidad de la remolacha. La combinación de musgo de turbera con NH4NO3 mostró valores comparativamente más bajos de biomasa fresca de planta, de biomasa fresca y seca de roseta y raíz, y de relación raíz‑roseta. Sin embargo, también se observaron valores más altos de actividad antioxidante y bioacumulación de ácido ascórbico, sólidos solubles totales, betacianinas, flavonoles y menos ácidos titulables, lo que resultó en un mayor índice de maduración y buena calidad. En general, la combinación de musgo de turbera con NH4NO3 condujo a una mayor calidad nutricional y antioxidante de las plantas de remolacha roja. Fil: Ejaz, Shaghef. Fil: Jezik, Karoline Maria.
