Con el fin de predecir rendimientos de betacianinas de raíz de Beta vulgaris L., para uso alimentario bajo condiciones de campo, se aplicó una ecuación potencial simple, ecuación de Richard y modelo de Werker en tres agroambientes, y determinaron curvas de crecimiento, desarrollo foliar, biomasa y metabolito. Se evaluaron siete variables del rendimiento, ocho de campo, cinco abióticas, 22 físico-químicas del suelo, y dos de extracción bioquímica. Los datos fueron analizados además por componentes principales. La producción de betacianinas en raíz se relacionó inversamente con su biomasa, lo que coincide con resultados de otros autores, que indican que el tamaño y peso del betabel correlacionan negativamente con la concentración de betacianinas, aunque éstos no reportan un modelo para dicha concentración. Los rendimientos de biomasa aérea estuvieron directamente relacionados con los de betacianinas (r2?0.90), resaltando que once de 17 nutrimentos esenciales fueron determinantes. Al quedar definidos los factores bióticos y abióticos que afectan el desarrollo de raíz, en los sitios de estudio, contra rendimientos de betacianinas, es posible gestionar bajo el modelo aplicado, las variables más significativas para optimizar el rendimiento, calidad y rentabilidad industrial en cada agroambiente.

Quality of Carrots Grown for Processing as Affected by Nitrogen Fertilization and Harvest TermIn 2007-2008 the effect of nitrogen fertilization and harvest term on quality of two carrot cultivars was investigated. The field experiment was carried out in Żelazna Experimental Station of Warsaw University of Life Sciences. Karotan F1and Trafford F1cultivars, commonly grown for juice industry, were the objects of the experiment. Carrot seeds were sown at the beginning of May. Nitrogen fertilization was applied in five rates, ranged from 0 to 120 kg·ha-1and in two terms — before sowing and in the middle of growing season. Roots were harvested in three terms: mid-September, mid-October and the first decade of November. After harvest there were determined: nitrates (NO3) content in carrot roots and juice, soluble solids, colour parameters of juice in CIE L*a*b*system. The dose and the term of nitrogen fertilization influenced nitrates content in carrots, and the highest NO3concentration was found in carrots fertilized with 120 kg·ha-1of N before sowing. Karotan showed higher nitrates accumulation than Trafford. The content of nitrates in the roots was markedly higher than in carrot juice. Nitrates content in carrots decreased with delaying of harvest time, in opposite to soluble solids content. Soluble solids content and colour parameters of carrot juice were not affected by nitrogen fertilization, but the lowest L*, a*and b*values were observed at the last term of harvest.
