“…Grain yields are extremely variable depending upon species and genotype, site, soil and weather conditions, growing season and agronomic practices. Grain yields from 1000 to 3000 kg ha -1 have been achieved in the United States (Myers, 1996) and in several countries of Northern Europe (Croatia, Slovak Republic, Austria and Germany) (Pospišil et al, 2006;Gimplinger et al, 2008); 1800-2300 kg ha -1 and exceptionally 4500 kg ha -1 in Argentina (Tosi and Ré, 2003); 5000 kg ha -1 or more under intensive cultivation in China (Wu et al, 2000); 1200-6700 kg ha -1 in southern Italy (Alba et al, 1997;Lovelli et al, 2005). The combination of its capacity to adapt to unfavourable growing conditions, such as low nutrient availability and a wide range of soil moisture, temperature and irradiation, as well as its tolerance to drought stress (Liu and Stützel, 2004), contribute to the plant's wide geographic adaptability to diverse environmental conditions, including marginal lands and semi-arid regions (Myers, 1996;Schahbazian et al, 2006).…”

“…Seeds are considered to have a unique composition of proteins, carbohydrates and lipids with regard to quantity and quality. They are generally high in protein content (14-18%) and in essential amino acids such as lysine, triptophan and sulphur-containing amino acids (Becker et al, 1981;Bressani, 1989;Zheleznov et al, 1997;Tosi et al, 2001;Pospišil et al, 2006). Noteworthy is the high content of arginine and histidine which makes amaranth interesting for child nutrition.…”

“…Which means that the more AP you have an increase in BA and the RS. Here, Pospisil et al (2006) reported positive and significant correlations between the AP and the length of the inflorescence and between the length of the inflorescence and the RS.…”

“…These results contrast with those reported by Pospisil et al (2006), who mention that fertilization has los tratamientos y por encima del testigo con diferencia de 29.84 g. Sin embargo, es de importancia específica observar respuestas para la variable RP en el tratamiento 8 con la dosis 80-40-00-2 kg ha -1 de N y 40 de fósforo con dos t ha -1 de compost de lombriz (Cuadro 3). El RP se atribuye a la composta cuando se deja de manera constante el nivel de N y P, con una diferencia de 3.97 g. Resultados similares muestran Ramírez et al (2011); Myers (1998) para condiciones de temporal con fertilizante químico.…”

“…Estos resultados contrastan con lo reportado por Pospisil et al (2006), quienes N= nitrógeno; P= Fósforo; K= Potasio; c= composta; AP= altura de planta; RM 2 = rendimiento por metro cuadrado; RP= rendimiento por planta; CV= coeficiente de variación; DMS= diferencia mínima significativa. no significant effect on the height of amaranth plant.…”
